Power amplifiers are a weak link in most audio systems. Most power amplifiers are well matched to the limitations of the CD format, but they fall well short of the capabilities of high-resolution formats. In contrast, the revolutionary AHB2 was specifically designed to deliver true high-resolution performance.\u003c\/p\u003e\n\u003ch4\u003eThe Need for Better Amplification\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eD\/A conversion technology has outpaced the development of new power amplifiers. This means that the power amplifier has become a limiting factor in many audio systems. For example, the noise and distortion produced by the Benchmark DAC2 D\/A converter is 20 to 30 dB lower than that produced by most high-quality power amplifiers. Until now, this meant that the DAC2 could not be fully appreciated. Benchmark set out to solve this problem by creating an amplifier that matches the performance of the DAC2.\u003c\/p\u003e\n\u003ch4\u003eA New and Different Power Amplifier\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eBenchmark had to look beyond existing amplifier technologies and explore some new and radical solutions. In its search, Benchmark engineers learned of two new patents on a new amplifier technology from THX. This was exactly the technology needed to build the new amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 uses the new and revolutionary THX-patented AAA™ technology to virtually eliminate all forms of distortion. This technology uses feed-forward error correction to eliminate the distortion that is normally produced by the output stage. No other audio amplifier comes close to delivering the clean, quiet, and robust power of the AHB2.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn its quest, Benchmark also focused on frequency response, output noise, drive current, damping factor, and reliability.

No amplifier delivers lower noise or lower distortion. The small, passively cooled chassis, cleanly delivers 480 Watts bridged mono into 6 Ohms, with additional reserves for driving difficult speaker loads. Unlike power-hungry Class A amplifiers, the AHB2 achieves a power efficiency that rivals that of a Class D (switching) power amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 will never produce audible distortion. In most playback systems, the distortion produced by the AHB2 will never even reach the 0 dB SPL threshold of hearing. This means that the distortion could not be heard, even if it could be played while the music was muted.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"I very much enjoyed my time evaluating the Benchmark AHB2 amplifier and can heartily recommend it to those seeking one of the lowest distortion and lowest noise amplifiers on the planet – one that is very musically transparent and easy on the ears to boot,\" reports Frank Alles at \u003cem\u003eStereo Times\u003c\/em\u003e.\u003c\/p\u003e\n\u003ch4\u003eDifficult Speaker Loads Are Handled with Ease\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eMany loudspeakers have frequencies at which their impedance drops to levels that are much lower than the \"nominal\" impedance. The AHB2 drives difficult phase angles and low impedances with ease. Stereo loads as low as 1.4 Ohms can be cleanly driven to full output levels. Most power amplifiers produce higher levels of distortion when the load impedance decreases. In contrast, the feed-forward error correction system in the AHB2 keeps the output clean when driving difficult loads. The AHB2 produces almost no measurable distortion at any rated load condition.\u003c\/p\u003e\n\u003ch4\u003eHigh Damping Factor, High Output Current\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 has a high damping factor that augments its extended low-end to deliver solid, well-controlled bass. This high damping factor also keeps the frequency response absolutely flat while driving speakers with large frequency-dependent impedance variations.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 can deliver up to 29 A peak to each channel simultaneously. This robust drive current easily handles some of the most demanding loudspeakers. The AHB2 has tightly regulated power supplies that keep the output clean while delivering high current.\u003c\/p\u003e\n\u003ch4\u003eExtreme Performance Often Requires a Radical Approach\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 amplifier is radically different than traditional audio amplifiers. Two new THX-patented feed-forward error-correction technologies eliminate most sources of distortion. An unconventional power supply maintains tight regulation and low ripple while minimizing magnetic fields. A low-gain topology optimizes the gain staging between the D\/A converter and the power amplifier while minimizing noise. Sophisticated shielding and star-quad signal distribution provide outstanding immunity to interference. A unique output stage incorporates Class H tracking power supply rails to improve efficiency. The result is that the cool-running AHB2 has a signal to noise ratio of 132 dB while distortion is at or below the measurement limits of the finest test equipment.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is the only amplifier that leverages the patented THX-AAA Technology™. This patented system reduces distortion to vanishingly low levels while enabling several power-saving techniques. A bipolar Class AB output stage delivers high output current and low noise. The THX-AAA Technology provides accurate cancellation of zero-crossing errors, exceeding the performance of the best Class A amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"The Benchmark AHB2 is a powerful and efficient amplifier with prodigious low levels of noise and distortion. The fact that it is also very musical and non-fatiguing, courtesy of THX's patented AAA Technology, is the icing on the cake. Benchmark Media and THX have a lot to be proud of for the development and implementation of the new technology the AHB2 represents,\" notes Frank Alles at \u003cem\u003eStereo Times\u003c\/em\u003e.\u003c\/p\u003e\n\u003ch4\u003eFeed-Forward Error Correction\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eTraditional Class AB amplifiers generate crossover distortion every time the push-pull output stage crosses 0 volts. This crossover distortion can be especially problematic at low playback levels.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, Class A amplifiers eliminate crossover distortion by keeping all output devices turned on at all times. This brute-force Class A approach solves the crossover distortion problem but it consumes lots of power while delivering very little to the speakers. The wasted power produces heat which must be dissipated into the listening space.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eClass A amplifiers eliminate crossover distortion but they suffer from high power consumption, poor damping, and limited output power. The AHB2 is the first amplifier to virtually eliminate crossover distortion without incurring the undesirable side effects of Class A amplification.\u003c\/p\u003e\n\u003ch4\u003eThe Importance of the First Watt\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eDick Olsher once said that \"the first Watt is the most important Watt\". From the first Watt to the last Watt, the AHB2 shows no evidence of crossover distortion.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, all conventional Class AB amplifiers have crossover-distortion artifacts. Traditional Class AB designs attempt to control distortion through the use of feedback. Unfortunately, these feedback systems have a limited ability to reduce the abrupt transients that are caused by output device crossover transitions. Feedback networks attempt to correct errors after they occur. In contrast, feed-forward networks can prevent errors before they occur.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eTHX-AAA Technology includes an ultra-clean low-power error-correction amplifier that runs in parallel with the high-power main amplifier. The correction amplifier actively drives the output while the main output devices transition between push and pull states. Like a Class A amplifier, the AHB2 shows no signs of crossover distortion. The feed-forward system virtually eliminates the errors that would have been produced by the output devices in the main amplifier.\u003c\/p\u003e\n\u003ch4\u003eHigh Efficiency – Green Never Sounded So Good!\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe THX-patented feed-forward error correction used in the AHB2 is so effective that biasing of the Class AB bipolar output devices can be reduced to unusually low levels. Benchmark has chosen to maintain a small bias current in the output stage, but this bias current is not critical to the distortion performance of the unit. The benefit of low bias current is that very little power is wasted as heat when the amplifier is idle. The AHB2 only draws 12 watts when idle, and less than 1\/2 watt in standby.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe feed-forward error correction also allows the use of Class H tracking power supply rails without the usual distortion-performance penalty. These tracking rails significantly improve the overall efficiency of the amplifier while the error correction keeps distortion nearly nonexistent. The AHB2 rivals the efficiency of Class D amplifiers while exceeding the sonic performance of power-hungry Class A designs. Green never sounded so good!\u003c\/p\u003e\n\u003ch4\u003eInnovative Low-Noise Power Supply\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eMost high-quality power amplifiers have linear power supplies, large toroidal transformers, and large banks of energy-storage capacitors. These linear supplies are usually unregulated and the capacitors help to remove ripple produced by the audio and by the AC line. In contrast, the AHB2 uses a tightly regulated resonant switching power supply that includes a very fast control loop. This control loop responds to audio-frequency load changes and keeps the supply voltage constant without the use of a large bank of capacitors. This active regulation is much more effective than capacitive energy-storage. Consequently, the peak power output of the AHB2 does not vary with line voltage or audio loading. The power supply rails maintain a constant voltage during audio peaks.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply in the AHB2 switches at frequencies that are well above audible frequencies. This eliminates mechanical hum while significantly reducing the strength of stray magnetic fields. For a given amount of power, magnetic field strength decreases as switching frequency increases. The lower field strengths also provide a significant reduction in size. High-frequency transformers and coils are also much smaller than line-frequency components. This size reduction contributes to the small physical size of the AHB2.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe switching power supply used in the AHB2 is a zero-voltage switching, resonant power converter. This means that the power devices in the supply switch near zero voltage and zero current, eliminating the large switching transients produced by conventional switching power supplies. The power supply in the AHB2 is actually much cleaner and quieter than a conventional linear supply.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply In the AHB2 is well over 90% efficient, much more efficient than linear supplies. This means that little power is lost to heat. The power-efficient AHB2 uses passive heat sinks to maintain cool operation. The AHB2 delivers high power without the need for fans. The unit runs cool, even when playing audio at full output levels. The absence of fan noise is absolutely essential in a high-resolution listening environment.\u003c\/p\u003e\n\u003ch4\u003e\"You Won’t Get a Cleaner Sounding Amp at Thrice Its Price\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"You won’t get a cleaner sounding amp even at thrice its price; you wouldn’t find a lower distortion amp that could drive almost anything out there and you can quote me on that anytime,\" reports Sandu Vitalie, \u003cem\u003esoundnews.net\u003c\/em\u003e, February 28, 2022, honoring the AHB2 with a Gold Award.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"With the right source and loudspeakers, it will sound highly engaging, always making you move, smile and toe-tap. While it’s indeed a linear and straight as a line amplifier, it was still highly dynamic and engaging sounding, trying to exceed my highest expectations.\"\u003c\/p\u003e\n\u003ch4\u003eLow-Noise Input Amplifiers\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe precision balanced inputs on the AHB2 are equipped with low-noise input amplifiers. Benchmark considers balanced inputs essential in a true high-resolution system. If balanced sources are not available, Benchmark sells unbalanced to balanced adapter cables that extend a 3-wire balanced connection back to the unbalanced source connectors. These adapter cables provide many of the advantages of fully balanced interconnects while providing full compatibility with all unbalanced sources.\u003c\/p\u003e\n\u003ch4\u003eLow Gain for Low System Noise\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is a low-gain design. Maximum output is not reached until the balanced inputs reach +22 dBu. This is a much higher signal level than is used at the input of most power amplifiers. High interface signal levels are required to achieve the best possible system signal to noise ratio (SNR). Most power amplifiers have far too much gain and consequently they suffer from poor noise performance. The AHB2 is 10 dB to 30 dB quieter than some of the very best power amplifiers on the market. A rear-panel gain switch can be used to set the AHB2 at higher gain settings if necessary. The low-gain setting is designed to interface directly with Benchmark DAC2 converters and other professional audio products.\u003c\/p\u003e\n\u003ch4\u003e\"Very Musically Transparent\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"I very much enjoyed my time evaluating the Benchmark AHB2 amplifier and can heartily recommend it to those seeking one of the lowest distortion and lowest noise amplifiers on the planet — one that is very musically transparent and easy on the ears to boot,\" remarks Frank Alles, \u003cem\u003eStereo Times\u003c\/em\u003e.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"Two remarkable things about the AHB2 are its relatively high power output, especially in mono mode, and its vanishingly low noise and distortion. Once you have heard a high-powered, ultra-clean amplifier, it’s hard to go back. When playing a top-quality recording, a high-powered amp like the AHB2 can give effortless reproduction of musical peaks with consistent timbres, no audible limiting, and no fear that the sound will fall apart when music gets loud and complex,\" reports Mike Prager, \u003cem\u003efutureaudiophile.com\u003c\/em\u003e, September 23, 2024.\u003c\/p\u003e\n\u003ch4\u003eBulletproof Protection System with No Relays\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 has a unique protection system that prevents damage from overloads and short circuits. The protection system monitors output voltage, output current, output distortion, output device SOA (safe operating area), power supply current, power supply voltage, AC line voltage, case temperatures, and power device temperatures. Fault conditions silently mute both output channels in order to protect the speakers and amplifier from damage. The amplifier outputs are also muted while the amplifier is turning on or off.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe mute circuits are fully electronic. There are no mechanical relays in the mute circuits. Our tests showed that relays are too slow to protect against certain fault events. Our tests also showed that relay contacts can add significant distortion as they deteriorate with use. The AHB2 is one of very few amplifiers that avoids the use of relays in the output stage. This means that the AHB2 will maintain its rated distortion performance after an unlimited number of power on\/off cycles.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's unique distortion monitoring system mutes the amplifier if it is excessively driven into clipping. This system protects tweeters from an overdriven amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's short circuit detection system is fast enough to fully protect the amplifier from events occurring at any output voltage or current.

To the best of our knowledge, no other D\/A converter has lower THD than the Benchmark DAC3.\u003c\/p\u003e\n\u003ch4\u003eHybrid Gain Control\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"HGC\" is Benchmark's unique Hybrid Gain Control system. The DAC3 combines active analog gain control, passive low-impedance attenuators, a 32-bit digital gain control, and a servo-driven volume control. All inputs are controlled by the rotary volume control. This volume control moves in response to commands from the remote control. Analog inputs are never converted to digital, and digital inputs never pass through an analog potentiometer. Digital inputs are precisely controlled in the 32-bit DSP system. The DSP system preserves precise L\/R balance, and precise stereo imaging, while avoiding any source of noise and distortion.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's unique passive output attenuators provide distortion-free gain reduction without reducing the dynamic range of the converter. The attenuators optimize the gain staging between the DAC3 and the power amplifier. This optimization is absolutely essential for maximizing the dynamic range of the entire playback system. Much of the success of the DAC1 and DAC2 converters can be attributed to the passive output attenuators. Musical details can be obscured by system noise whenever a preamplifier and power amplifier are improperly matched. The\" HGC \" system will make full use of your power amplifier's dynamic range.

Most digital systems clip signals that exceed 0 dBFS. The 0 dBFS limitation seems reasonable, as 0 dBFS is the highest sinusoidal signal level that can be represented in a digital system. However, a detailed investigation of the mathematics of PCM digital systems will reveal that inter-sample peaks may reach levels slightly higher than +3 dBFS while individual samples never exceed 0 dBFS. These inter-sample overs are common in commercial releases, and are of no consequence in a PCM system until they reach an interpolation process. But, for a variety of reasons, virtually all audio D\/A converters use an interpolation process.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe interpolation process is absolutely necessary to achieve 24-bit state-of-the art conversion performance. Unfortunately, inter-sample overs cause clipping in most interpolators. This clipping produces distortion products that are non-harmonic and non-musical . We believe these broadband distortion products often add a harshness or false high-frequency sparkle to digital reproduction. The DAC3 avoids these problems by maintaining at least 3.5 dB of headroom in the entire conversion system. We believe this added headroom is a groundbreaking improvement.\u003c\/p\u003e\n\u003ch4\u003eMulti-Mode Asynchronous USB System\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eBenchmark's USB system supports USB Audio 2.0, DSD, and USB Audio 1.1. It is frequency agile, and will follow sample rate changes initiated by the computer and\/or the media playback software. In all modes the USB communications are asynchronous in order to eliminate unnecessary sources of jitter.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe DAC3 has a low-jitter master clock which controls the transfer of audio data from the computer to the USB sub-system. The computer asynchronously transfers audio data to a buffer in the DAC3. The contents of the buffer are then asynchronously transferred to the D\/A conversion subsystem. This second asynchronous transfer eliminates any traces of jitter that accumulate as the data is transferred between the USB and conversion subsystems. No traces of jitter-induced distortion are measurable to our measurement limits (better than -150 dBFS).\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThis truly represents the state-of-the art. Enjoy the convenience of computer playback without compromise. The Asynchronous USB system supports USB Audio 2.0 for high-resolution 192kHz, and DSD playback.

An easy-to-install driver adds 192 kHz and DSD capabilities to Windows operating systems.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eAn asynchronous, driverless USB Audio 1.1 mode supports sample rates up to 96 kHz. This USB mode can be selected from the front panel or from the remote control. The driverless USB Audio 1.1 mode allows quick plug-and-play connections to Windows, MAC, iOS, and Linux operating systems without installing drivers. Just plug in the USB, and the DAC3 becomes an available audio device.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe USB subsystem remains active when the DAC3 is powered down.

The 4:1 redundancy reduces noise and distortion to levels that set new benchmarks. The conversion system at the core of the DAC3 is as good as it gets. The analog circuits that follow the D\/A converter are carefully designed. Benchmark has leveraged its long history of building high-end analog audio equipment, in order to create an outstanding output stage.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe conversion system in the DAC3 achieves a 6 dB signal to noise improvement through the use of 4:1 summing. The ES9028PRO D\/A is an 8-channel 32-bit converter. In the DAC3, four channels are summed in the analog domain to form each of the two output channels.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe 4:1 summing also improves the THD. The non-linearities in individual conversion channels are averaged across the four summed channels and incoherent non-linearities are attenuated by 6 dB.\u003c\/p\u003e\n\u003ch4\u003eHome Theater Bypass\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe DAC3 can be integrated into a home theater system.

Sophisticated shielding and star-quad signal distribution provide outstanding immunity to interference. A unique output stage incorporates Class H tracking power supply rails to improve efficiency.

In contrast, feed-forward networks can prevent errors before they occur.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eTHX-AAA Technology includes an ultra-clean low-power error-correction amplifier that runs in parallel with the high-power main amplifier. The correction amplifier actively drives the output while the main output devices transition between push and pull states. Like a Class A amplifier, the AHB2 shows no signs of crossover distortion. The feed-forward system virtually eliminates the errors that would have been produced by the output devices in the main amplifier.\u003c\/p\u003e\n\u003ch4\u003eHigh Efficiency – Green Never Sounded So Good!\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe THX-patented feed-forward error correction used in the AHB2 is so effective that biasing of the Class AB bipolar output devices can be reduced to unusually low levels.

Benchmark set out to solve this problem by creating an amplifier that matches the performance of the DAC2.\u003c\/p\u003e\n\u003ch4\u003eA New and Different Power Amplifier\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eBenchmark had to look beyond existing amplifier technologies and explore some new and radical solutions.

This was exactly the technology needed to build the new amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 uses the new and revolutionary THX-patented AAA™ technology to virtually eliminate all forms of distortion. This technology uses feed-forward error correction to eliminate the distortion that is normally produced by the output stage. No other audio amplifier comes close to delivering the clean, quiet, and robust power of the AHB2.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn its quest, Benchmark also focused on frequency response, output noise, drive current, damping factor, and reliability.

No amplifier delivers lower noise or lower distortion. The small, passively cooled chassis, cleanly delivers 480 Watts bridged mono into 6 Ohms, with additional reserves for driving difficult speaker loads. Unlike power-hungry Class A amplifiers, the AHB2 achieves a power efficiency that rivals that of a Class D (switching) power amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 will never produce audible distortion. In most playback systems, the distortion produced by the AHB2 will never even reach the 0 dB SPL threshold of hearing.

The AHB2 drives difficult phase angles and low impedances with ease. Stereo loads as low as 1.4 Ohms can be cleanly driven to full output levels. Most power amplifiers produce higher levels of distortion when the load impedance decreases. In contrast, the feed-forward error correction system in the AHB2 keeps the output clean when driving difficult loads. The AHB2 produces almost no measurable distortion at any rated load condition.\u003c\/p\u003e\n\u003ch4\u003eHigh Damping Factor, High Output Current\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 has a high damping factor that augments its extended low-end to deliver solid, well-controlled bass. This high damping factor also keeps the frequency response absolutely flat while driving speakers with large frequency-dependent impedance variations.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 can deliver up to 29 A peak to each channel simultaneously. This robust drive current easily handles some of the most demanding loudspeakers.

Two new THX-patented feed-forward error-correction technologies eliminate most sources of distortion. An unconventional power supply maintains tight regulation and low ripple while minimizing magnetic fields. A low-gain topology optimizes the gain staging between the D\/A converter and the power amplifier while minimizing noise. Sophisticated shielding and star-quad signal distribution provide outstanding immunity to interference. A unique output stage incorporates Class H tracking power supply rails to improve efficiency. The result is that the cool-running AHB2 has a signal to noise ratio of 132 dB while distortion is at or below the measurement limits of the finest test equipment.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is the only amplifier that leverages the patented THX-AAA Technology™. This patented system reduces distortion to vanishingly low levels while enabling several power-saving techniques. A bipolar Class AB output stage delivers high output current and low noise. The THX-AAA Technology provides accurate cancellation of zero-crossing errors, exceeding the performance of the best Class A amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"The Benchmark AHB2 is a powerful and efficient amplifier with prodigious low levels of noise and distortion. The fact that it is also very musical and non-fatiguing, courtesy of THX's patented AAA Technology, is the icing on the cake. Benchmark Media and THX have a lot to be proud of for the development and implementation of the new technology the AHB2 represents,\" notes Frank Alles at \u003cem\u003eStereo Times\u003c\/em\u003e.\u003c\/p\u003e\n\u003ch4\u003eFeed-Forward Error Correction\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eTraditional Class AB amplifiers generate crossover distortion every time the push-pull output stage crosses 0 volts. This crossover distortion can be especially problematic at low playback levels.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, Class A amplifiers eliminate crossover distortion by keeping all output devices turned on at all times. This brute-force Class A approach solves the crossover distortion problem but it consumes lots of power while delivering very little to the speakers. The wasted power produces heat which must be dissipated into the listening space.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eClass A amplifiers eliminate crossover distortion but they suffer from high power consumption, poor damping, and limited output power. The AHB2 is the first amplifier to virtually eliminate crossover distortion without incurring the undesirable side effects of Class A amplification.\u003c\/p\u003e\n\u003ch4\u003eThe Importance of the First Watt\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eDick Olsher once said that \"the first Watt is the most important Watt\". From the first Watt to the last Watt, the AHB2 shows no evidence of crossover distortion.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, all conventional Class AB amplifiers have crossover-distortion artifacts. Traditional Class AB designs attempt to control distortion through the use of feedback. Unfortunately, these feedback systems have a limited ability to reduce the abrupt transients that are caused by output device crossover transitions. Feedback networks attempt to correct errors after they occur. In contrast, feed-forward networks can prevent errors before they occur.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eTHX-AAA Technology includes an ultra-clean low-power error-correction amplifier that runs in parallel with the high-power main amplifier. The correction amplifier actively drives the output while the main output devices transition between push and pull states. Like a Class A amplifier, the AHB2 shows no signs of crossover distortion. The feed-forward system virtually eliminates the errors that would have been produced by the output devices in the main amplifier.\u003c\/p\u003e\n\u003ch4\u003eHigh Efficiency – Green Never Sounded So Good!\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe THX-patented feed-forward error correction used in the AHB2 is so effective that biasing of the Class AB bipolar output devices can be reduced to unusually low levels. Benchmark has chosen to maintain a small bias current in the output stage, but this bias current is not critical to the distortion performance of the unit. The benefit of low bias current is that very little power is wasted as heat when the amplifier is idle. The AHB2 only draws 12 watts when idle, and less than 1\/2 watt in standby.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe feed-forward error correction also allows the use of Class H tracking power supply rails without the usual distortion-performance penalty. These tracking rails significantly improve the overall efficiency of the amplifier while the error correction keeps distortion nearly nonexistent. The AHB2 rivals the efficiency of Class D amplifiers while exceeding the sonic performance of power-hungry Class A designs. Green never sounded so good!\u003c\/p\u003e\n\u003ch4\u003eInnovative Low-Noise Power Supply\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eMost high-quality power amplifiers have linear power supplies, large toroidal transformers, and large banks of energy-storage capacitors. These linear supplies are usually unregulated and the capacitors help to remove ripple produced by the audio and by the AC line. In contrast, the AHB2 uses a tightly regulated resonant switching power supply that includes a very fast control loop. This control loop responds to audio-frequency load changes and keeps the supply voltage constant without the use of a large bank of capacitors. This active regulation is much more effective than capacitive energy-storage. Consequently, the peak power output of the AHB2 does not vary with line voltage or audio loading. The power supply rails maintain a constant voltage during audio peaks.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply in the AHB2 switches at frequencies that are well above audible frequencies. This eliminates mechanical hum while significantly reducing the strength of stray magnetic fields. For a given amount of power, magnetic field strength decreases as switching frequency increases. The lower field strengths also provide a significant reduction in size. High-frequency transformers and coils are also much smaller than line-frequency components. This size reduction contributes to the small physical size of the AHB2.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe switching power supply used in the AHB2 is a zero-voltage switching, resonant power converter. This means that the power devices in the supply switch near zero voltage and zero current, eliminating the large switching transients produced by conventional switching power supplies. The power supply in the AHB2 is actually much cleaner and quieter than a conventional linear supply.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply In the AHB2 is well over 90% efficient, much more efficient than linear supplies. This means that little power is lost to heat. The power-efficient AHB2 uses passive heat sinks to maintain cool operation. The AHB2 delivers high power without the need for fans. The unit runs cool, even when playing audio at full output levels. The absence of fan noise is absolutely essential in a high-resolution listening environment.\u003c\/p\u003e\n\u003ch4\u003eLow-Noise Input Amplifiers\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe precision balanced inputs on the AHB2 are equipped with low-noise input amplifiers. Benchmark considers balanced inputs essential in a true high-resolution system. If balanced sources are not available, Benchmark sells unbalanced to balanced adapter cables that extend a 3-wire balanced connection back to the unbalanced source connectors. These adapter cables provide many of the advantages of fully balanced interconnects while providing full compatibility with all unbalanced sources.\u003c\/p\u003e\n\u003ch4\u003eLow Gain for Low System Noise\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is a low-gain design. Maximum output is not reached until the balanced inputs reach +22 dBu. This is a much higher signal level than is used at the input of most power amplifiers. High interface signal levels are required to achieve the best possible system signal to noise ratio (SNR). Most power amplifiers have far too much gain and consequently they suffer from poor noise performance. The AHB2 is 10 dB to 30 dB quieter than some of the very best power amplifiers on the market. A rear-panel gain switch can be used to set the AHB2 at higher gain settings if necessary. The low-gain setting is designed to interface directly with Benchmark DAC2 converters and other professional audio products.\u003c\/p\u003e\n\u003ch4\u003eBulletproof Protection System with No Relays\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 has a unique protection system that prevents damage from overloads and short circuits. The protection system monitors output voltage, output current, output distortion, output device SOA (safe operating area), power supply current, power supply voltage, AC line voltage, case temperatures, and power device temperatures. Fault conditions silently mute both output channels in order to protect the speakers and amplifier from damage. The amplifier outputs are also muted while the amplifier is turning on or off.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe mute circuits are fully electronic. There are no mechanical relays in the mute circuits. Our tests showed that relays are too slow to protect against certain fault events. Our tests also showed that relay contacts can add significant distortion as they deteriorate with use. The AHB2 is one of very few amplifiers that avoids the use of relays in the output stage. This means that the AHB2 will maintain its rated distortion performance after an unlimited number of power on\/off cycles.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's unique distortion monitoring system mutes the amplifier if it is excessively driven into clipping. This system protects tweeters from an overdriven amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's short circuit detection system is fast enough to fully protect the amplifier from events occurring at any output voltage or current. This system detects abnormal loads and instantly mutes the outputs.

The high-current SpeakON connectors are designed for heavy-duty commercial sound systems and provide much better electrical connections than binding posts. Benchmark highly recommends the use of the twist-lock SpeakON output connectors. We also highly recommend the use of our top-quality professional-grade speaker cables.\u003c\/p\u003e","brand":"Benchmark","offers":[{"title":"New \/ Black \/ Standard \/ New","offer_id":45983319949485,"sku":"NEW-BEAHB2-BLK","price":3499.0,"currency_code":"USD","in_stock":true},{"title":"New \/ Black \/ Standard \/ Demo","offer_id":45983319982253,"sku":"DEMO-BEAHB2-BLK","price":2758.51,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Open Box","offer_id":45983320015021,"sku":"OPEN-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Cosmetically Blemished","offer_id":45983320047789,"sku":"BLEM-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Factory Refreshed","offer_id":45983320080557,"sku":"RFRB-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/beahb2_blk-large__31203.1724186561.1280.1280_b6413201-d0bb-4f1d-8557-557030aae473.jpg?v=1778130526"},{"product_id":"benchmark-dac3-hgc-digital-to-analog-converter-black","title":"Benchmark DAC3 HGC Digital-to-Analog Converter - Black","description":"\u003ch2\u003e\n\u003ca name=\"X0239498a489bbf646bb2153c8f2c1fd00bffec3\"\u003e\u003c\/a\u003eBenchmark DAC3 HGC Digital-to-Analog Converter\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003ca name=\"what-you-need-to-know\"\u003e\u003c\/a\u003eWhat You Need to Know\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\n\u003ca name=\"one-box-that-masters-three-jobs\"\u003e\u003c\/a\u003eOne Box That Masters Three Jobs\u003c\/h4\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"FirstParagraph\"\u003eThe Benchmark DAC3 HGC is a reference-grade digital-to-analog converter, a true analog-and-digital preamplifier, and a world-class headphone amplifier in a single half-rack chassis.

The AHB2 drives difficult phase angles and low impedances with ease. Stereo loads as low as 1.4 Ohms can be cleanly driven to full output levels. Most power amplifiers produce higher levels of distortion when the load impedance decreases. In contrast, the feed-forward error correction system in the AHB2 keeps the output clean when driving difficult loads.

Two new THX-patented feed-forward error-correction technologies eliminate most sources of distortion. An unconventional power supply maintains tight regulation and low ripple while minimizing magnetic fields. A low-gain topology optimizes the gain staging between the D\/A converter and the power amplifier while minimizing noise. Sophisticated shielding and star-quad signal distribution provide outstanding immunity to interference. A unique output stage incorporates Class H tracking power supply rails to improve efficiency. The result is that the cool-running AHB2 has a signal to noise ratio of 132 dB while distortion is at or below the measurement limits of the finest test equipment.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is the only amplifier that leverages the patented THX-AAA Technology™.

This crossover distortion can be especially problematic at low playback levels.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, Class A amplifiers eliminate crossover distortion by keeping all output devices turned on at all times. This brute-force Class A approach solves the crossover distortion problem but it consumes lots of power while delivering very little to the speakers. The wasted power produces heat which must be dissipated into the listening space.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eClass A amplifiers eliminate crossover distortion but they suffer from high power consumption, poor damping, and limited output power. The AHB2 is the first amplifier to virtually eliminate crossover distortion without incurring the undesirable side effects of Class A amplification.\u003c\/p\u003e\n\u003ch4\u003eThe Importance of the First Watt\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eDick Olsher once said that \"the first Watt is the most important Watt\". From the first Watt to the last Watt, the AHB2 shows no evidence of crossover distortion.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eIn contrast, all conventional Class AB amplifiers have crossover-distortion artifacts. Traditional Class AB designs attempt to control distortion through the use of feedback. Unfortunately, these feedback systems have a limited ability to reduce the abrupt transients that are caused by output device crossover transitions. Feedback networks attempt to correct errors after they occur. In contrast, feed-forward networks can prevent errors before they occur.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eTHX-AAA Technology includes an ultra-clean low-power error-correction amplifier that runs in parallel with the high-power main amplifier. The correction amplifier actively drives the output while the main output devices transition between push and pull states. Like a Class A amplifier, the AHB2 shows no signs of crossover distortion. The feed-forward system virtually eliminates the errors that would have been produced by the output devices in the main amplifier.\u003c\/p\u003e\n\u003ch4\u003eHigh Efficiency – Green Never Sounded So Good!\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe THX-patented feed-forward error correction used in the AHB2 is so effective that biasing of the Class AB bipolar output devices can be reduced to unusually low levels. Benchmark has chosen to maintain a small bias current in the output stage, but this bias current is not critical to the distortion performance of the unit. The benefit of low bias current is that very little power is wasted as heat when the amplifier is idle. The AHB2 only draws 12 watts when idle, and less than 1\/2 watt in standby.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe feed-forward error correction also allows the use of Class H tracking power supply rails without the usual distortion-performance penalty. These tracking rails significantly improve the overall efficiency of the amplifier while the error correction keeps distortion nearly nonexistent. The AHB2 rivals the efficiency of Class D amplifiers while exceeding the sonic performance of power-hungry Class A designs. Green never sounded so good!\u003c\/p\u003e\n\u003ch4\u003eInnovative Low-Noise Power Supply\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eMost high-quality power amplifiers have linear power supplies, large toroidal transformers, and large banks of energy-storage capacitors. These linear supplies are usually unregulated and the capacitors help to remove ripple produced by the audio and by the AC line. In contrast, the AHB2 uses a tightly regulated resonant switching power supply that includes a very fast control loop. This control loop responds to audio-frequency load changes and keeps the supply voltage constant without the use of a large bank of capacitors. This active regulation is much more effective than capacitive energy-storage. Consequently, the peak power output of the AHB2 does not vary with line voltage or audio loading. The power supply rails maintain a constant voltage during audio peaks.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply in the AHB2 switches at frequencies that are well above audible frequencies. This eliminates mechanical hum while significantly reducing the strength of stray magnetic fields. For a given amount of power, magnetic field strength decreases as switching frequency increases. The lower field strengths also provide a significant reduction in size. High-frequency transformers and coils are also much smaller than line-frequency components. This size reduction contributes to the small physical size of the AHB2.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe switching power supply used in the AHB2 is a zero-voltage switching, resonant power converter. This means that the power devices in the supply switch near zero voltage and zero current, eliminating the large switching transients produced by conventional switching power supplies. The power supply in the AHB2 is actually much cleaner and quieter than a conventional linear supply.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe power supply In the AHB2 is well over 90% efficient, much more efficient than linear supplies. This means that little power is lost to heat. The power-efficient AHB2 uses passive heat sinks to maintain cool operation. The AHB2 delivers high power without the need for fans. The unit runs cool, even when playing audio at full output levels. The absence of fan noise is absolutely essential in a high-resolution listening environment.\u003c\/p\u003e\n\u003ch4\u003e\"You Won’t Get a Cleaner Sounding Amp at Thrice Its Price\"\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003e\"You won’t get a cleaner sounding amp even at thrice its price; you wouldn’t find a lower distortion amp that could drive almost anything out there and you can quote me on that anytime,\" reports Sandu Vitalie, \u003cem\u003esoundnews.net\u003c\/em\u003e, February 28, 2022, honoring the AHB2 with a Gold Award.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003e\"With the right source and loudspeakers, it will sound highly engaging, always making you move, smile and toe-tap.

Benchmark considers balanced inputs essential in a true high-resolution system. If balanced sources are not available, Benchmark sells unbalanced to balanced adapter cables that extend a 3-wire balanced connection back to the unbalanced source connectors. These adapter cables provide many of the advantages of fully balanced interconnects while providing full compatibility with all unbalanced sources.\u003c\/p\u003e\n\u003ch4\u003eLow Gain for Low System Noise\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is a low-gain design. Maximum output is not reached until the balanced inputs reach +22 dBu. This is a much higher signal level than is used at the input of most power amplifiers. High interface signal levels are required to achieve the best possible system signal to noise ratio (SNR). Most power amplifiers have far too much gain and consequently they suffer from poor noise performance. The AHB2 is 10 dB to 30 dB quieter than some of the very best power amplifiers on the market. A rear-panel gain switch can be used to set the AHB2 at higher gain settings if necessary.

The protection system monitors output voltage, output current, output distortion, output device SOA (safe operating area), power supply current, power supply voltage, AC line voltage, case temperatures, and power device temperatures. Fault conditions silently mute both output channels in order to protect the speakers and amplifier from damage. The amplifier outputs are also muted while the amplifier is turning on or off.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe mute circuits are fully electronic. There are no mechanical relays in the mute circuits. Our tests showed that relays are too slow to protect against certain fault events. Our tests also showed that relay contacts can add significant distortion as they deteriorate with use. The AHB2 is one of very few amplifiers that avoids the use of relays in the output stage. This means that the AHB2 will maintain its rated distortion performance after an unlimited number of power on\/off cycles.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's unique distortion monitoring system mutes the amplifier if it is excessively driven into clipping. This system protects tweeters from an overdriven amplifier.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eBenchmark's short circuit detection system is fast enough to fully protect the amplifier from events occurring at any output voltage or current. This system detects abnormal loads and instantly mutes the outputs. A status display shows the exact cause of the fault so that the problem can be corrected.\u003c\/p\u003e\n\u003ch4\u003eSpeakON Output Connectors\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eThe AHB2 is equipped with high-quality binding posts, and SpeakON output connectors. The high-current SpeakON connectors are designed for heavy-duty commercial sound systems and provide much better electrical connections than binding posts. Benchmark highly recommends the use of the twist-lock SpeakON output connectors. We also highly recommend the use of our top-quality professional-grade speaker cables.\u003c\/p\u003e","brand":"Benchmark","offers":[{"title":"New \/ Silver \/ Standard \/ New","offer_id":45982851793069,"sku":"NEW-BEAHB2-SIL","price":3499.0,"currency_code":"USD","in_stock":true},{"title":"New \/ Silver \/ Standard \/ Demo","offer_id":45982851825837,"sku":"DEMO-BEAHB2-SIL","price":2998.37,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Rackmount \/ New","offer_id":45983232065709,"sku":"NEW-BEAHB2-BLK-RAK","price":3599.0,"currency_code":"USD","in_stock":true},{"title":"New \/ Silver \/ Rackmount \/ New","offer_id":45983257952429,"sku":"NEW-BEAHB2-SIL-RAK","price":3599.0,"currency_code":"USD","in_stock":true},{"title":"New \/ Black \/ Standard \/ New","offer_id":45983319949485,"sku":"NEW-BEAHB2-BLK","price":3499.0,"currency_code":"USD","in_stock":true},{"title":"New \/ Black \/ Standard \/ Demo","offer_id":45983319982253,"sku":"DEMO-BEAHB2-BLK","price":2758.51,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Open Box","offer_id":45983320015021,"sku":"OPEN-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Cosmetically Blemished","offer_id":45983320047789,"sku":"BLEM-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false},{"title":"New \/ Black \/ Standard \/ Factory Refreshed","offer_id":45983320080557,"sku":"RFRB-BEAHB2-BLK","price":2899.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/beahb2_sil-large__33236.1725995001.1280.1280_b3072b33-a6bf-46ff-a422-350d9eb6f0e9.jpg?v=1778095239"},{"product_id":"benchmark-dac3-hgc-digital-to-analog-converter","title":"Benchmark DAC3 HGC Digital-to-Analog Converter","description":"\u003ch2\u003e\n\u003ca name=\"X0239498a489bbf646bb2153c8f2c1fd00bffec3\"\u003e\u003c\/a\u003eBenchmark DAC3 HGC Digital-to-Analog Converter\u003c\/h2\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003ca name=\"what-you-need-to-know\"\u003e\u003c\/a\u003eWhat You Need to Know\u003c\/h3\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003ch4\u003e\n\u003ca name=\"one-box-that-masters-three-jobs\"\u003e\u003c\/a\u003eOne Box That Masters Three Jobs\u003c\/h4\u003e\n\u003cp class=\"MsoNormal\" style=\"margin-bottom: 0mm; line-height: 6.0pt; mso-line-height-rule: exactly;\"\u003e\u003cspan style=\"font-size: 6.0pt; mso-bidi-font-size: 12.0pt;\"\u003e \u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"FirstParagraph\"\u003eThe Benchmark DAC3 HGC is a reference-grade digital-to-analog converter, a true analog-and-digital preamplifier, and a world-class headphone amplifier in a single half-rack chassis.
