GETTING THE MOST FROM THE NAD T 773

Thank you for choosing NAD.

The T 773 A/V Receiver is a technologically advanced and highly capable product — yet we have invested
great effort in making it simple and easy to use. The T 773 delivers a range of genuinely useful options for
surround sound and stereo listening alike, using powerful digital signal processing and superbly accurate
digital-audio circuitry. However, we have also been careful to ensure that the A/V Receiver is as musically
transparent and spatially accurate as possible, incorporating much of what we’ve learned from a quarter-
century’s experience designing audio and home-theater components. As with all our products, NAD’s
“Music First” design philosophy guided the T 773’s design, such that it can confidently promise you both
state-of-the-art surround home-theater 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 NAD T 773, and get the most from this powerful and flexible home-
theater component.

One more thing: We urge you to register your T 773 ownership on the NAD Worldwide Web site:
