THANK YOU FOR CHOOSING NAD.
The M12 Digital Preamp DAC is a technologically advanced and highly
capable product — yet we have invested great effort in making it simple
and easy to use. The M12 is an ultra-high resolution digital audio hub that
interfaces to musical sources and renders the digital or analog source
perfectly to power amplifiers and active loudspeakers.
Overall 24 bit accuracy is guaranteed by the 35 bit data path with 24 bit
coefficients and 62 bit accumulation which is dithered back to 35 bits after
DSP functions. And because of the super high resolution, even 24 bit files
are processed without truncation or loss of information.
As with all our products, NAD’s “Music First” design philosophy guided the M12’s
design. The M12 delivers a range of genuinely useful options using powerful
digital signal processing and superbly accurate digital-audio circuitry. However,
we have also been careful to ensure that the M12 is as musically transparent,
faithful to every detail and spatially accurate as possible, incorporating much of
what we’ve learned from more than a quarter-century’s experience designing
audio, video and home-theater components.
We encourage you to take a few minutes now to read right through this
manual. Investing a little time here at the outset might save you a good
deal of time later, and is by far the best way to ensure that you make the
most of your investment in the M12.
