Outstanding Technical Precision and Audio Performance
With full 24-bit, 192 kHz analog-to-digital and digital-to-analog conversion, NAD's Masters Series M15 HD2 7.1-channel surround sound preamplifier will make the most of all of your source material. In yet another of the company's unique approaches, NAD has employed multiple two-channel DACs in a dual differential mode, a configuration that yields superb sonic results. The engineers have also tailored the M15 HD2's circuit design to deliver a level of technical precision and audio performance that is among the best you'll find at anywhere near the price, and even way beyond.
Stunning Video Performance
With a masterful level of video performance, the latest digital video technology, and full support for all 3D formats up to 1080p, the Masters Series M15 HD2 will carry you into a new world of home theater. With six HDMI inputs and two outputs, one simple connection decodes digital signals for a true HD display. All sources are output in their native resolution, so you can watch movies and videos in their purest and intended form. The M15 HD2 also fully supports the latest HDMI standards, including Audio Return Channel (ARC) and Consumer Electronic Control (CEC).
Maximum Audio Performance
Even though the M15 HD3 excels with video material, it takes full advantage of NAD's decades of experience designing components with a 'Music First' audiophile philosophy. The sophisticated power supply plays a key role here.
By using separate analog and digital power supplies, the M15 HD2 can provide maximum audio performance. A high power switch mode for the digital and video section, and a linear power supply for the ultra high-speed audio processing, provides the required high current and stable voltages to maintain audio precision. Analog and digital sections are kept completely separate for maximum sonic performance. Standby power consumption is also ultra-low at <0.5W.
The M15 HD2 supports all popular surround sound formats, including NAD's exclusive EARS and the latest Dolby TrueHD and DTS-MA formats with excellent musical dynamics.
Award-Winning MDC Innovation
Don't worry about the M15 HD2 becoming obsolete anytime soon as technology changes. The M15 HD2 uses NAD's advanced MDC Modular Design Construction architecture.
MDC is NAD's innovative solution to the ever-changing world of AV technology. With the ability to replace simple plug-in modules, MDC gives you peace-of-mind. You no longer have to be frustrated by technology obsolescence, because MDC allows you to upgrade to new features and technology without destroying your original AV investment. Recognized as one of the most important innovations in the past decade, MDC has also received the prestigious international Red Dot Design Award.
Beauty AND Brains
The M15 HD2 offers the best 'brains' and processing power for the most advanced surround sound system. Everyday operation is simple and intuitive with multiple customizable settings, so all you have to do is sit back and enjoy your music and movies. Its simplicity is evident in the elegant industrial design that is fresh yet classic.
The M15 HD2 simplifies the process of speaker calibration, thanks to onboard Audyssey technology, a user-friendly option for sound balancing and room correction. By using a supplied microphone and Audyssey MultEQ XT, you can finely tune the sound in a specific room for an optimal audio experience. It's like having your own acoustic engineer set up your system. The Audyssey MultEQ Pro software and calibration system is also included with the NAD.
Optimal Connection Flexibility
You get a whole system's worth of audio and video connections with the M15 HD2. In the analog audio realm, you have seven analog line level inputs, one analog external 7.1 input, Zone 2, 3, and 4 analog outputs, an analog audio 7.1 pre output, and two subwoofer outputs. Digital audio connections consist of four coaxial digital audio inputs, four optical digital audio inputs, two coaxial digital audio outputs, and two optical digital audio outputs.
How about video connections? The M15 HD2 gives you six HDMI inputs, two HDMI outputs, four S-video inputs, one S-video output, three component video inputs, one component video output, and one monitor output.
Equipped with a rear panel IR remote input and outputs, programmable 12V triggers, and an RS-232 port, the M15 HD2 can easily integrate with many advanced home automation systems, such as AMX and Creston. A popular option for the M15 HD2 is NAD's IPD 2 Dock for iPod, so you can take advantage of your iPod's digital music library. |
