  • NAD MASTERS SERIES M51 DIRECT DIGITAL DAC

    Product Description

    Product Details:

    The M51 Direct DigitalTM DAC uses the same high precision digital processing as our groundbreaking M2 Direct DigitalTM Amplifier,but in a new format that easily interfaces with high performance analogue components, including our M3 Dual Mono IntegratedAmplifier. Part of NAD‚¬„s Masters Digital Suite, the M51 features extremely low noise, low distortion, wide dynamic range, superblinearity and extremely low digital jitter. The M51 accepts PCM data rates up to 24 bit 192 kHz making it perfect for listening toincreasingly popular high resolution downloads.

    Features

    > Digital Innovation

    NAD‚¬„s exclusive Direct DigitalTM technology was first introduced in our groundbreaking M2 Direct DigitalTM Amplifier. The M51 is the first standalone DAC to exploit the extreme precision and speed that only Direct DigitalTM technology can offer. Instead of using the Direct DigitalTM processor to drive the high power output stage of a power amplifier, the M51 employs a line level analogue output that will perfectly interface with any analogue system.

    > The Advantage of Direct DigitalTM

    NAD‚¬„s unique technology uses a very powerful processingengine that operates at much higher speed and with muchgreater accuracy than typical D-to-A converters. Runningat 108MHz, the M51 resamples the incoming PCM (pulsecode modulated) signal and converts it to PWM (pulse widthmodulation) with a sampling rate of 844kHz. Operating in adifferential mode with double precision the M51 has state-of-the-art specifications for low noise and freedom from distortion.Digital jitter at the output, both uncorrelated and correlated, isvanishingly low even if the incoming signal is corrupted.

    > Next Generation Connectivity

    While the M51 includes the industry standard SPDIF inputs,including AES/EBU, Optical and Coaxial. The M51 alsoincludes the latest USB technology fully supporting 192kHzsample rates, allowing direct connection of a PC or Mac. HDMIprovides an encrypted HD Audio connection in PCM‚¬„s nativeI2S format up to 24 bit 192kHz.

    > Home Theatre 2.0

    The M51 offers two HDMI inputs and one output with videopass through. This opens up the possibility of using the M51Direct DigitalTM DAC as the heart of a Home Cinema 2.0 system using the linear PCM soundtrack from Blu-ray or DVD to makea compelling 2-channel high definition theatre presentation.Many symphony orchestras and some specialty music labelsare also releasing HD recordings on Blu-ray.

    > Pure Performance

    The incredible precision of the M51‚¬„s processing engine givesmusic a vibrancy and transient accuracy that must be heardto be appreciated. A pure Class A analogue stage with verylow output impedance provides the perfect interface to yourfavourite amplifier. A patented real-time digital error correctioncircuit corrects for any nonlinearities in the output buffer anddigital reconstruction filter. Both balanced and single-endedoutputs are available.

    > More Than Just a DAC

    M51 is a fully functional digital preamp with six digital inputsand one of the world‚¬„s best volume controls. As a ‚¬˜preamp‚¬„ itis totally noise and distortion free because all switching andvolume control is done in the digital domain. Whether you wantto get into Computer Audio, Home Cinema 2.0 or just wantto upgrade your CD Player, the M51 Direct DigitalTM DAC willget the best possible performance from every digital format.All this innovation, performance and flexibility comes withlegendary NAD sound quality and affordability.
