NAD M15 HD2 AV Surround Sound Preamplifier
'Music First' Digital Audio

With full 24-bit 192kHz analogue-to-digital and digital-to-analogue conversion, our M15 HD2 will make the most of even the best available source material. In yet another uncommon approach, we have employed multiple 2-channel DACs in a dual differential mode, a configuration that yields superb sonic results. We have tailored our circuit design to deliver a level of technical precision and audio performance that could be considered perfect.

Award-Winning MDC Innovation

MDC is our uncommon answer 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 reddot design award.

Optimal Flexibility

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 our IPD 2 Dock for iPod so you can take advantage of your iPod's digital music library.

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 M15 HD2 will carry you into a new world of home theatre. 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).

Smart Power

By using separate analogue and digital power supplies, the M15 HD2 can provide maximum audio performance. A high power switch mode for the digital and video section, and linear power supply for the ultra high-speed audio processing, provides the required high current and stable voltages to maintain audio precision. Analogue and Digital sections are kept completely separate for maximum sonic performance. Standby power consumption is also ultra-low at <0.5W.

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.

Customized Sound

The M15 HD2 supports all popular surround sound formats, including our exclusive EARS and the latest Dolby TrueHD and DTS-MA formats with excellent musical dynamics. In addition to Audyssey MultEQ Pro, you are presented with 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.
NAD M25 7-Channel Amplifier
Power is a critical component to sound quality. The demand placed on amplifiers by today's elaborate home theatre systems requires additional headroom so that they reproduce clean sound free from the distortion of a taxed amplifier. Fortunately for the M25, at 160-watts per channel, it is one of the most powerful amplifiers built today. It's one of the cleanest amplifiers with a rated distortion of 0.03 (All channels driven simultaneously, from 20Hz to 20kHz.) The M25 easily exceeds THX's most stringent certification level, Ultra 2.

Unlike most receivers and amplifiers, the M25 can deliver its full-rated power, free from distortion for hours on end. Custom designed heat sinks and temperature regulated, variable speed cooling fans work to keep the M25 running cool under the most severe operating conditions.

The M25 is actually made up of seven individual mono block amplifiers with each channel using a balanced junction FET input stage to eliminate cross-talk, resulting in exceptionally low levels of noise and distortion. Additionally, NAD employs a unique electronic ground isolation circuit to prevent ground loop noise in the system—a common problem with many complex multi-channel systems.

NAD's proprietary PowerDrive circuitry measures each channel's dynamic impedance individually and computes the optimum power supply voltage required to drive the output stage for maximum power and efficiency.
