NAD M51 Amplificator

Descrierea produsului
What Hi-Fi, Five
Star Award: This NAD can display details and sonic textures that
cheaper DACs struggle to convey. This is as relevant when listening to
16-bit/44.1kHz CD playback as it is when indulging in a 24-bit/192kHz
high-res file. Hi-Fi World, M51 Best DAC for 2012: It has a rare beauty of sound to
it that so many others lack, it has a superb preamplifier built-in, and
may be the instrument of choice for those people who value these
qualities above all others. Stereophile: rdquo;Nothing raised an eyebrow, and the claimed benefits in
jitter rejection and filter design have obviously paid offrdquo;, rdquo;all the
musical detail was there, and it sounded as if there were more meat on
the musical boneshellip;rdquo;Digital Innovation: Best DAC NAD\'s Direct Digitaltrade; technology is
unique in both its extreme precision and in its speed. This advancement
was first introduced in the NAD M2 Direct Digital Amplifier to worldwide
acclaim. Now this innovative Direct Digitaltrade; technology is available as
a standalone DAC. Instead of using the Direct Digitaltrade; processor to
drive a high power output stage, we employ a line level analogue output
that will perfectly interface with any analogue system with the M51
Direct Digital DAC. How Direct Digitaltrade; Operates: NAD\'s technology uses a very powerful
processing engine that operates at much higher speed and with much
greater accuracy than typical Digital-to-Analogue converters. Running at
108MHz, the M51 resamples the incoming pulse code modulated (PCM)
signal and converts it to a pulse width modulation signal (PWM) with a
sampling rate of 844kHz. Operating in a differential mode with double
precision, the M51 has state-of-the-art specifications for low noise and
freedom from distortion. The extreme headroom afforded by the 35-bit
architecture allows for a DSP-based volume control that does not reduce
resolution. Even with 24-bit high definition signals, the output can be
attenuated by 66dB (very, very quiet) before bit truncation begins. Pure Performance: The incredible precision of the M51\'s processing
engine gives music a vibrancy and transient accuracy that must be heard
to be appreciated. The conversion process from PCM to PWM completely
eliminates any jitter present on the incoming signal; again, offering
state-of-the-art performance in this most important parameter. Best DAC
2012 CEPro AwardDue to the very high clock speed and mathematical
precision of our reconstruction filters, the resulting audio signal is
totally free of digital artifacts like ringing. A Pure Class A analogue
stage with very low output impedance provides the perfect interface to
your favourite amplifier. Also, both balanced and single-ended outputs
are available. Next Generation Connectivity: While the M51 includes the industry
standard SPDIF, AES/EBU, Optical and Coaxial inputs, it also includes
the latest USB technology called USB Audio Class 2. USB Audio Class 2
supports sample rates of 192kHz releasing the previous limitation of USB
at 96kHz. A device USB port is included allowing direct connection of a
PC or Mac. The M51 offers two HDMI inputs and one output with video
pass through. This opens up the possibility of using the M51 Direct
Digital DAC as the heart of a Video 2.0 system using the mandatory
two-channel linear PCM soundtrack from Blu-ray or DVD to make a
compelling two-channel high definition theatre presentation. Many
symphony orchestras and some specialty music labels are also released in
HD recordings on Blu-ray or DVD. The M51 is fully 3D video compatible
but there is no surround sound decoding or video processing. More than Just a DAC: M51 is a fully functional digital preamp with
seven digital inputs and one of the world\'s best volume controls. As a
\'preamp\' it is totally noise and distortion free because all switching
and volume control is done in the digital domain. There are no analogue
circuits except for the Class A buffer at the output of the DAC. While
input selection is available from a front panel control, volume can only
be selected via remote control. The supplied IR remote also features
controls for NAD\'s matching M50 Digital Music Player. Serial control is
available via RS-232 IR and 12V trigger inputs allow the M51 to fully
integrate with advanced automation systems. The M51 introduces many \'firsts\' for the DAC product category: first
to support HDMI, first to support USB Audio Class 2 with support for
192kHz, the first to use digital error correction, and the first 35-bit
architecture to be found in a DAC. Whether you want to get into computer
audio, \'Home Cinema 2.0\' or just want to upgrade your CD player, the
M51 Direct Digital DAC will get the best possible performance from every
digital format. All this innovation, performance and flexibility come
with NAD\'s legendary sound quality and affordability. NAD USB 2.0 Audio Driver for Windows PCs (XP, Vista and 7): In order
to stream your computer audio via the M51, ensure that the Sound or
Audio device setting of your computer is set to NAD USB Audio 2.0.
Download the NAD USB 2.0 Audio Driver (click on the downloads tab on
this page) and install this driver to your computer by following the
instructions provided. Minimum system requirement: Microsoft Windows XP
Service Pack 2 or higher, Microsoft Windows 78. Note: Any drivers
previously loaded must be uninstalled prior to installing this driverFor MAC Users: Minimum Mac OS X Snow Leopard (version 10.6) and later
versions include USB Audio 2.0 drivers and therefore it is not
necessary to install the NAD USB 2.0 Audio driver. Ensure the Sound
device of your Mac is set to NAD USB Audio 2.0.
