John is particularly proud of what he and Parasound have accomplished together. \"The circuits I design for Parasound are extremely sophisticated and are typical of products that are far more expensive,\" John says. \"I can't think of any other audio products that offer nearly as much bang for the buck.\"\r\n\r\n\u003c\/p\u003e\u003ch4\u003eEvery Part is Chosen for Accuracy and Reliability\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eEvery part used in the A 52+ is carefully chosen for its accuracy and reliability. Metal film resistors with 1% tolerance are selected for their precision and because their values don't drift as they heat up during operation. Polypropylene and mica capacitors are used extensively for their superior linearity and low dielectric absorption. Semiconductors are selected for superior performance in their specific roles in the circuit. Gold has the best conductivity of any metal, so Parasound uses high quality gold-plated input connectors and speaker terminals. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe double-sided circuit boards are FR4 glass epoxy for long-term durability. The chassis is made of heavy gauge steel to safely house the internal circuitry. This attention to detail when selecting parts makes the difference between a very good amplifier and an outstanding amplifier. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eHighly Efficient and Quiet Power Supply\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe heart of the Halo A 52+ power supply is a 1.5 kVA toroid power transformer, chosen for its efficiency, low hum field, and high power rating. Encapsulating this massive power transformer in an epoxy-filled steel canister assures ultra-quiet performance. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe A 52+ power transformer employs multiple independent secondary windings, so that each amplifier channel has its own power supply, assuring more than ample DC voltage at all times and under all conditions. It also reduces inter-channel crosstalk that can blur the sound and impair the correct sense of where instruments, dialogue and effects are positioned. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eEach channel's +\/- 80 Vdc B+ and B- supply rails use high-speed rectifier diodes and two Rubycon custom-made 10,000uF electrolytic filter capacitors, chosen for their low Equivalent Series Resistance (ESR), dielectric absorption and resistance to high temperature. In addition, these filter capacitors are bypassed with smaller polypropylene capacitors to reduce AC ripple in the DC supply and to further eliminate noise and interference that is generated in AC power lines from computers and other appliances in the home. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eRelay-Bypassed Soft Start Circuit\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eWhen the A 52+ is first turned on, there is a significant amount of in-rush current required to charge the enormous power supply capacitors. In order to slow down and suppress this in-rush current and to prevent nuisance tripping of a household circuit breaker, Parasound employs a NTC (negative temperature coefficient) thermistor. A thermistor cuts the in-rush current by approximately 50%. In a few seconds as it heats up to its operating temperature it it's essentially a jumper wire with zero ohms resistance. However, the A 52+ goes one step further for this circuit. After the NTC resistor has done its job of suppressing in-rush current a relay with gold contacts automatically activates to jump across it to completely bypass it. This extra step insures that the thermistor does not restrict any current whatsoever when the A 52+ is in full operation. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eAudio Circuit Path Topology\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eParasound's circuit topology is a hybrid of carefully chosen discrete transistors that result in superior performance at each stage. We use JFETs (Junction Field Effect Transistors) for the input voltage amplifier stage; MOSFETs (Metal Oxide Field Effect Transistors) for the drivers of a second voltage amplifier stage and bipolar transistors for the current amplifier output stage. Discrete transistors are more sonically accurate than integrated circuits commonly used by other brands. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eComplementary Configuration\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eEach stage of amplification has transistors fed by the positive DC power supply and complementary transistors fed by the negative DC power supply. Thus, half of the devices amplify the positive half of the musical waveform while the other half of the devices amplify the negative half. This complementary topology is inherently linear, which reduces distortion and improves sonic accuracy. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eInput Stage with Matched Pairs of Discrete JFETs\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe A 52+'s input stage uses matched pairs of discrete JFETs arranged in a differential configuration. JFETs are ideal for the input stage because their inherently high impedance is unaffected by the impedance of source components. (Ordinary bi-polar transistors are low impedance devices) Differential configuration provides superior noise reduction. These precision input JFETs are also cascaded to produce the current necessary to drive the MOSFET drivers in the following stage. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eDriver Stage Boasting Tube-like Sonic Qualities\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe driver stage provides critical amplification for which Parasound employed a complementary matched pair of MOSFETs selected for their tube-like sonic qualities. MOSFETs tend to generate less odd-order higher harmonic distortion than bipolar transistors. This is important because odd-order distortion sounds unnatural and fatiguing to the human ear, whereas even-order distortion is less offensive because it is consonant, rather than dissonant. The MOSFET driver stage prevents the harshness and brittle sound so often found in other solid state amplifiers. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eThe Output Stage\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe amplifier's sonic characteristics are established by its input and driver stages. Now, the sole job of its output stage is to deliver the enormous current and voltage from its power supply to the speakers. Bipolar output transistors are better than MOSFETS in the output stage because of their higher safe operating area (SOA) and inherent ruggedness. Each channel's output stage employs four pairs of high current (15-ampere) bipolar transistors to insure long-term reliability, even with continuous high power operation and challenging speaker loads. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eLightning-fast (60 MHz) transistors respond instantly to complex demands in the musical signal, virtually eliminating distortions that occur with \"slower\" transistors. Slew rate limiting and Transient Intermodulation Distortion (TIM) are simply not an issue in the A 52+. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eNatural Sounding Class A-A\/B Operation\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003ePure Class A operation provides the purest sound. However, an amplifier operating entirely in Class A would be enormous, highly inefficient, and generate far too much heat. Class A\/B combines the main advantage of Class A with the efficiency of Class B operation. It is a compromise that reduces the heat generated in pure Class A operation and the higher- order odd harmonic distortions created in class B. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eIn Class AB, the driver and output stages are always partially turned on, which provides a nominal amount of pure class A operation. At higher power levels, when the musical waveform swings from positive to negative and vice versa, each bank of transistors is allowed to rest momentarily. This resting, or quiescent time, makes it possible to deliver high amounts of power without overheating. It also makes possible the use of passive cooling and avoid fans, whose noise can be heard over the music. The A 52+ input and driver stages employ pure Class A while its output stage operates with higher level of pure Class A power than many amplifiers selling for twice or three times its price. The result is less fatiguing, more natural sound. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eTotal Protection - DC Servos\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eDirect Current (DC) burns out speakers. Every power amplifier must have some way to insure that DC from its power supply never reaches its + or - speaker terminals. Most amplifiers simply use hand-adjustable trim controls to reduce their DC offset or capacitors to block DC. Unfortunately, trim controls can allow DC offset to increase over time, and even the most expensive capacitors in the audio signal path will \"veil\" sonic clarity and attenuate bass response. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eParasound power amplifiers incorporate ingenious and fast-acting DC servo circuits, completely eliminating the need for coupling and blocking capacitors. The A 52+ is direct (DC) coupled from its input jacks to its speaker terminals. This advanced circuitry never needs adjustment or maintenance. It operates outside the audio signal path to keep the DC offset at the output of the A 52+ at a constant 0.00 Vdc. The results are startling clarity, freedom from listening fatigue, and formidable bass response. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eTotal Protection - Relays\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eEach channel of the A 52+ has a high-quality protection relay with gold-plated contacts for long-term reliability. These relays function to protect either the amplifier, the speakers, or both. When the A 52+ is first powered on, these relays remain open for three seconds as the positive and negative power supplies stabilize and reach equilibrium. This prevents annoying popping or other transient noises. Relay protection also prevents damage to your speakers in case of a catastrophic amplifier failure. Any amplifier that doesn't use relay protection for its speaker outputs compromises the safety of the amplifier and your speakers. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eTotal Protection - Current Overload\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eSpecialized current-sensing transistors are connected to the output stages of the A 52+ to constantly monitor the current flow through the output transistors. If the current drawn by this stage exceeds a predetermined safe level due to a load impedance below 1 ohm or a short circuit at the speaker terminals, the output relay will open immediately to prevent the output transistors or other parts from failing. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eTotal Protection - Fuses\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eEach channel of the amplifier has two fuses for its positive and negative DC voltage rails. These fuses provide backup protection in case the over-current protection does not work in time, or if an internal part fails. In the event of a part failure, these fuses halt operation to minimize damage to additional parts. \u003c\/p\u003e","brand":"Parasound","offers":[{"title":"New","offer_id":45981736566957,"sku":"NEW-PAHA52P-BLK","price":4000.0,"currency_code":"USD","in_stock":true},{"title":"Demo","offer_id":45981736599725,"sku":"DEMO-PAHA52P-BLK","price":4000.0,"currency_code":"USD","in_stock":false},{"title":"Open Box","offer_id":45981736632493,"sku":"OPEN-PAHA52P-BLK","price":4000.0,"currency_code":"USD","in_stock":false},{"title":"Cosmetically Blemished","offer_id":45981736665261,"sku":"BLEM-PAHA52P-BLK","price":4000.0,"currency_code":"USD","in_stock":false},{"title":"Used","offer_id":45981736698029,"sku":"USED-PAHA52P-BLK","price":3250.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/PAHA52P_BLK_FRONT-Large__69681.1712937715.1280.1280.jpg?v=1778125850"},{"product_id":"rotel-rmb-1504-four-channel-power-amplifier-black","title":"Rotel RMB-1504 Four-Channel Power Amplifier - Black","description":"\u003ch3\u003eSuperb Four-Channel Power Amp for Home Theater, Distributed Audio, and More \u003c\/h3\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe RMB-1504 Class AB four-channel amplifier delivers on the ongoing commitment of performance without compromise, building on over 55 years of Rotel amplifier design and in-house manufacturing of hi-fi electronics.

The quality of that amplification shapes everything you hear — every movie moment, every music performance, every spatial detail.\u003c\/p\u003e\n\u003cp\u003eThe Bryston 9B³ is the five-channel version of Bryston’s legendary 9B series. It delivers 200 watts per channel. And unlike most multi-channel amplifiers, it is not a single large amplifier divided into five sections.\u003c\/p\u003e\n\u003cp\u003eEach of the five channels is a fully independent, self-contained module — its own circuit board, its own power supply, its own toroidal transformer. No channel shares power with any other. The five channels are independent in the same way that five separate monoblock amplifiers would be.\u003c\/p\u003e\n\u003ch3\u003eWhy Independent Power Supplies Matter\u003c\/h3\u003e\n\u003cp\u003eIn most multi-channel amplifiers, all channels share one power supply. When one channel demands a surge of power — a loud film effect, a bass transient — it draws from the same pool as the others. That competition shows up as compressed dynamics and a flattened sense of space.\u003c\/p\u003e\n\u003cp\u003eThe 9B³ eliminates this problem. Each channel draws from its own dedicated supply. A loud moment on the center channel has no effect on what the left or right channels can deliver. All five channels can run at full rated power at the same time.\u003c\/p\u003e\n\u003ch3\u003eThe Salomie Circuit — Bryston’s Patented Innovation\u003c\/h3\u003e\n\u003cp\u003eEvery Cubed Series amplifier uses Bryston’s patented Salomie input circuit, developed with the late Dr. Ioan Alexandru Salomie. According to Bryston, the circuit uses an array of 12 active devices at the first gain stage to act as a super-linear input buffer.\u003c\/p\u003e\n\u003cp\u003eThe buffer’s job is to catch and remove distortion and noise before they enter the main signal path. In most amplifiers, anything that gets into the input gets amplified right along with the music. The Salomie circuit stops that before it starts.\u003c\/p\u003e\n\u003cp\u003eBryston describes the results as dramatically less input-stage distortion, improved rejection of electromagnetic and radio-frequency noise, and standby power below 500mW. The 9B³ is the first five-channel Bryston amplifier to include this circuit.\u003c\/p\u003e\n\u003ch3\u003eModular Design — Built for the Long Term\u003c\/h3\u003e\n\u003cp\u003eThe 9B³ is orderable in three-, four-, or five-channel versions. Additional channel modules can be added later as your system grows. And if a channel ever needs service, it can be removed and replaced independently — without returning the whole amplifier.\u003c\/p\u003e\n\u003cp\u003eThis modular serviceability is rare in multi-channel amplifiers. Most competing designs require the entire unit to be returned for even a single-channel repair. The 9B³’s construction makes long-term ownership significantly more practical.\u003c\/p\u003e\n\u003ch3\u003eNetwork Monitoring and Control\u003c\/h3\u003e\n\u003cp\u003eThe 9B³ has a built-in Ethernet port that hosts its own web page. From any browser on your network, you can monitor each channel’s temperature, see clipping alerts, mute individual channels, and power the amplifier on or off. Firmware updates can also be applied this way.\u003c\/p\u003e\n\u003cp\u003eFor custom installation and home automation, an RS-232 serial port integrates with Crestron, Control4, Savant, and similar platforms. A DC trigger input and output handle automated power switching with processors and other components in your system.\u003c\/p\u003e\n\u003ch3\u003eSoftStart — Protection Built In\u003c\/h3\u003e\n\u003cp\u003eSoftStart is a microprocessor-controlled startup sequence. When the 9B³ powers on, it gradually ramps up its current draw instead of pulling full load all at once. This protects your speakers from startup transients and prevents tripping household circuit breakers — a real concern with a 65-pound amplifier drawing significant startup current.\u003c\/p\u003e\n\u003ch3\u003eBuild and Finish\u003c\/h3\u003e\n\u003cp\u003eThe chassis is machined and anodized aluminum.

Your processor needs dedicated pre-out connections, one per channel. From there, the 9B³ drives your speakers directly. You’ll also need speaker cables from each output to each speaker. Balanced XLR connections are recommended.\u003c\/p\u003e\n\u003ch3\u003eIs the 9B³ compatible with my speakers?\u003c\/h3\u003e\n\u003cp\u003eAt 200 watts per channel into 8 ohms and 300 watts into 4 ohms, the 9B³ handles the vast majority of home theater speakers, including demanding low-efficiency designs. Because each channel has its own independent supply, all five can run at full power simultaneously. Call us at \u003ca href=\"tel:+18009420220\"\u003e800-942-0220\u003c\/a\u003e if you’d like help confirming a match.\u003c\/p\u003e\n\u003ch3\u003eCan I start with fewer than five channels?\u003c\/h3\u003e\n\u003cp\u003eYes. The 9B³ is available in three-, four-, or five-channel configurations. If you start with three or four channels, you can add modules later. The chassis and internal infrastructure are already in place. Bryston sells individual channel modules separately for this purpose.\u003c\/p\u003e\n\u003ch3\u003eWhat is the Salomie circuit?\u003c\/h3\u003e\n\u003cp\u003eIt is Bryston’s patented input circuit, developed with the late Dr. Ioan Alexandru Salomie. According to Bryston, 12 active devices at the first gain stage act as a super-linear buffer, removing distortion and filtering EMI and RFI noise before they reach the signal path. The 9B³ is the first five-channel Bryston amp to use it.\u003c\/p\u003e\n\u003ch3\u003eWhy does modular construction matter for service?\u003c\/h3\u003e\n\u003cp\u003eEach channel module is a self-contained, removable assembly. If a channel needs repair, that module can be pulled and replaced without returning the whole amplifier. This matters over a 10-year ownership horizon. Most competing multi-channel amplifiers require a full return for any single-channel failure — the 9B³ does not.\u003c\/p\u003e\n\u003ch3\u003eDoes the 9B³ work with home automation systems?\u003c\/h3\u003e\n\u003cp\u003eYes. The built-in Ethernet interface provides a web page for monitoring and control from any browser. RS-232 serial integrates with Crestron, Control4, Savant, and similar platforms. DC trigger in and out handle automated power sequencing. Network control allows per-channel temperature monitoring, clipping alerts, muting, and firmware updates.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between the 17-inch and 19-inch versions?\u003c\/h3\u003e\n\u003cp\u003eThe 17-inch faceplate fits standard home audio furniture. The 19-inch version adds front handles and suits rack installation. A 19-inch PRO version is also available — it adds a rack-mountable dress panel and rear per-channel trim pots for fine level adjustment.\u003c\/p\u003e\n\u003cp\u003eThe amplifier electronics and specs are identical across all faceplate options. Both versions’ dimensions are listed in the spec table above.\u003c\/p\u003e\n\u003ch3\u003eWhat does SoftStart do?\u003c\/h3\u003e\n\u003cp\u003eSoftStart is a microprocessor-controlled power-on sequence. Instead of pulling full current at startup, the 9B³ ramps up gradually. This protects your speakers from the transient that would otherwise occur at power-on, and prevents the amplifier from tripping household circuit breakers — a practical concern with a large, high-power amplifier.\u003c\/p\u003e\n\u003ch3\u003eDoes the 9B³ need ventilation? Can I rack-mount it?\u003c\/h3\u003e\n\u003cp\u003eYes, it needs ventilation. The 9B³ runs warm and uses convection cooling — heat rises through the chassis naturally. Leave clearance above and around the unit. Do not install it in a sealed enclosure.\u003c\/p\u003e\n\u003cp\u003eFor rack use, leave at least one rack unit of open space above the amplifier, or use a rack with active ventilation. The 19-inch PRO version is the correct rack-mountable configuration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2\u003eWhat’s in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eBryston 9B³ Five-Channel Amplifier — Black, 19-Inch Faceplate, Green LED\u003c\/li\u003e\n\u003cli\u003eIEC AC power cable\u003c\/li\u003e\n\u003cli\u003eOwner’s manual\u003c\/li\u003e\n\u003cli\u003eWarranty and registration documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Audio Advisor?\u003c\/h2\u003e\n\u003cdiv class=\"ec-titlebox-text\"\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f3b5.svg\" alt=\"music note emoji\" width=\"20\"\u003e \u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e40+ Years of Expertise\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— Since 1981, we’ve helped over a million music lovers find the right gear.\u003c\/p\u003e\n\u003cp\u003e\u003cimg class=\"emoji\" role=\"img\" draggable=\"false\" src=\"https:\/\/s.w.org\/images\/core\/emoji\/17.0.2\/svg\/1f504.svg\" alt=\"repeat emoji\" width=\"20\"\u003e \u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003e60-Day Money-Back Guarantee\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003e— Take your time.

Thanks to its high performance, build quality, and Parasound engineering, ZoneMaster is the new standard in residential and commercial amplification. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eAmong the ZoneMaster 12's many specialized features are a speaker level input for expanding systems without pre out jacks, two bus inputs that can be routed to any zone, bus loop output jacks for passing audio to another amp, summed Mono mode that combines L and R for single speaker applications, and separate level controls for all twelve channels. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eSystem integration features include independent audio sensing triggers (one for each zone), six independent 12 volt trigger inputs (one for each zone), looping 12 volt trigger outputs for each zone, and a master 12 volt trigger input to turn all zones on-off. Zone 1 (channel 1 and 2) are higher power for more demanding applications. Detachable speaker connectors accept up to 12 gauge wire. ZoneMaster also has short circuit and overheat protection with front panel indicators and 0.5 watt standby power consumption, which meets Energy Star specs. \u003c\/p\u003e\r\n\r\n\u003ch4\u003eThe Speaker Level Input Connector\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe speaker level input is an additional type of audio input that any zone can select as its source. The speaker level input enables the ZoneMaster 12 to connect to any audio receiver or stereo system even if it lacks preamp output jacks. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThis is a high impedance input and the ZoneMaster 12’s speaker level input can connect to the speaker terminals on any receiver or amplifier. This will not reduce its output power or degrade the sound quality of the speakers that are already connected directly to the “host” receiver or amplifier. Audio connected to the Speaker Level input connector can be routed to any zone by setting each zone’s Input switch to the Bus position. Speaker level audio is also converted to line level and routed to the Bus Loop Out jacks which provide a line level output to drive additional amplifiers.\u003c\/p\u003e\r\n\r\n\u003ch4\u003eSpeaker A and B Outputs\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eThe ZoneMaster 12 is equipped with connections for two speakers on each channel (labeled A and B). This unique feature gives system designers greater flexibility and can usually avoid the added expense, complexity, heat and power consumption of additional amplifiers. The ability of the ZoneMaster 12 to drive two pair of speakers per channel is credited to Parasound’s 2 ohm stable high current design. \u003c\/p\u003e\r\n\r\n\u003cp align=\"justify\"\u003eTypical applications for using both Speaker A and B outputs might include a large living room with four ceiling speakers. Another use for the B speakers could be in a subzone like a bathroom or hallway adjacent to the room where the A speakers are installed. This adjacent subzone might also use a passive in-wall volume control to adjust its listening level separately.\u003c\/p\u003e\r\n\r\n\u003ch4\u003eSpeaker A and B Impedance\u003c\/h4\u003e\r\n\r\n\u003cp align=\"justify\"\u003eWhen you select the Stereo Mode the R and L channels are each capable of driving speaker loads as low as 2 ohms. An example of a 2 ohm load is one 4 ohm speaker connected to a channel’s speaker output A while another 4 ohm speaker is connected to the same channel’s speaker output B. When driving 2 ohm loads ensure the amplifier has adequate ventilation.\u003c\/p\u003e","brand":"Parasound","offers":[{"title":"New","offer_id":45983202869421,"sku":"NEW-PAZM12-BLK","price":3000.0,"currency_code":"USD","in_stock":true},{"title":"Used","offer_id":45983202902189,"sku":"USED-PAZM12-BLK","price":3000.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0750\/3708\/1773\/files\/PAZM12_BLK_01-Large__17726.1693418692.1280.1280__90210.1750690274.1280.1280_20b99d6a-27f7-4670-baab-f4a66ee6ecfa.jpg?v=1778162984"},{"product_id":"bryston-9b-five-channel-amplifier-silver-17-inch-faceplate-with-green-leds","title":"Bryston 9B³ Five-Channel Amplifier - Silver - 17 Inch Faceplate with Green LEDs","description":"\u003ch2\u003e\n\u003ca name=\"bryston-9b%C2%B3-five-channel-amplifier\"\u003e\u003c\/a\u003eBryston 9B³ Five-Channel Amplifier\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\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\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=\"Xd49492fe69b38dd4f1679dc72180fdfea6bafac\"\u003e\u003c\/a\u003eFive True Bryston Amplifiers in One Chassis\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 Bryston 9B³ Five-Channel Amplifier is not a home theater compromise—it’s five fully independent Bryston amplifier modules sharing one chassis, each with its own toroidal transformer and power supply, each delivering 200 watts into 8 ohms and up to 300 watts into 4 ohms.

Using technologies originally developed for the exclusive Marantz Reference Series, this flexible amplifier boasts many possible uses.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eFor example, the MM7055 is ideal for a 5.1 home theater system. You can use it to power speakers in different areas of your home; stereo reproduction in two rooms plus a mono channel for secondary areas such as a den or kitchen. For more complex home theater systems, the MM7055 pairs with one or several MM7025s to help create a totally immersive “7.1” or “9.1” audio experience.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe MM7055 produces 140 watts of high current output from each of its five channels. This is “real world” power measured across the full audio bandwidth (20 Hz – 20 kHz) at 8 ohms with 0.08% Total Harmonic Distortion. Among other attributes, this means the MM7055 is capable of long-term power delivery into low impedance speakers.\u003c\/p\u003e\n\u003ch4\u003eInside the MM7055\u003c\/h4\u003e\n\u003cp align=\"justify\"\u003eA massive power supply includes a multiple-secondary EI-core transformer and over 65,000 µF of custom-designed energy storage capacity. Critical circuit components from many world-class suppliers were chosen only after extensive listening tests. Among these, the LAPT Hyper Power output devices were first used in Reference Series components. Current feedback topology insures astounding accuracy and control under high-drive conditions.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003ePhysically, the MM7055’s output stages mount on an extruded aluminum “thermal tunnel” for efficient heat dissipation.
