THANK YOU FOR CHOOSING NAD.
The NAD C 390DD is a new concept in amplification exemplified by
leading edge audio system architecture. The C 390DD has no analog
stages in its signal path, keeping music in the digital domain right up to
the speaker output. All preamplifier functions are executed in the digital
domain without the phase shift, noise and distortion that plague all
analog designs. The C 390DD has small footprint, large power, low energy
consumption, future-proof upgradability, software defined operation,
backward compatibility, easy integration and a new high definition system
architecture. The C 390DD’s 35 bit architecture and 108MHz master clock
make it as one of the most accurate DAC technologies available.
As with all our products, NAD’s “Music First” design philosophy guided the
C 390DD design that it can confidently promise you both state-of-the-art
technology and audiophile-quality music listening for years to come.
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 C 390DD.
One more thing: We urge you to register your C 390DD ownership on the
NAD Worldwide Web site:
