T 773 OWNER'S MANUAL ADDENDUM
2 2 2 2 2
One of the benefits of the T 773 A/V Receiver is its capability for software upgrades. As NAD develops new
features, we issue new operational software.
This T 773 has a new version of software installed. There are several new features that are not described
in the Owner's Manual that are outlined below, along with the page reference to the original instruction.
One exciting new feature is the substitution of the HDCD decoding format with the new Dolby Digital Pro
Logic IIx.

Dolby Pro Logic IIx (page 24)
Dolby Digital Pro Logic IIx and Dolby Prologic IIx processes both stereo and 5.1 signals into a 6.1*- or 7.1-
channel output. For both Pro Logic IIx processes you can choose Movie or Music modes to tailor your listening
experience to source material. For two channel signals Pro Logic IIx Music mode also features three
additional user controls; Dimension, Center Width, and Panorama. The following chart shows the channels
available assuming they are enabled in the SPEAKER SETTINGS OSD menu;

Setup Menus
Since the T 773 was introduced, we have been asked for more flexible options in the Setup Menus. This
resulted in adding a more ergonomic interface and new options such as a menu for the Zone settings.
Zone Settings (page 17 Advanced Options)
POWER STATE
There are two settings to allow the second zone to power on or off from the HTR 2 remote control instead
of using the ZR 2 remote control. With the HTR 2; toggling the POWER STATE to ON will power on the second
zone as indicated in the T 773's VFD, toggling the POWER STATE to OFF will power off the second zone.
VOLUME CTRL
There are now two primary settings for the second zone volume control; FIXED and VARIABLE. When set to
VARIABLE the second zone volume will be adjustable via the ZR 2. When set to FIXED the second zone
volume will be set to the preset level as shown on the ZONE SETTINGS, LEVEL. The FIXED setting is the
preferred setting when the second zone amplifier has its own volume control (or when using a distribution
amplifier with passive 'impedance matching' volume controls).
LEVEL (page 12 MS OUT)
This sets the audio volume level at initial power on of the second zone MS OUT (MultiSource Out). Set this
level from -75dB to +18dB (the default setting is -20dB). To change this level the VOLUME CTRL setting must
be set to VARIABLE. Once the VOLUME CTRL setting is set to FIXED, the level cannot be adjusted. To mute
the MS OUT; press ENTER on the HTR 2 and an "M" will show beside the audio volume level to indicate
muting.
AUTO TRIG IN
This feature was formerly named AUTO TRIGGER, and still functions as it did before.
ZONE SPEAKER
The internal amplifiers can be used by the MS OUT, either all or some of SPEAKERS A or SPEAKERS B. Assign
either speaker set to be active when the second zone powers on. The settings for ZONE SPEAKER are;
SPEAKER A, SPEAKER B and NONE.
Note: Using this feature requires that the Pre-Out/Main-In jumper be removed and the MS Out be connected
to the Main-In of the desired channels using RCA to RCA cables (not supplied). To access the Speaker A
+ B feature, the Front L + R amplifier channels should be used. The Front L +R Pre-Out should then be
connected to the Surround Back L + R Amp-In jacks with the main zone front speakers attached to these
speaker outputs. Obviously, any amplifier channels used for second zone will no longer be available in the
main zone. This does allow the 7 channel T 773 to operate a 5.1 surround system in the main zone and a
simultaneous independent stereo feed to a second remote zone.
Advanced Options (page 17)
Dolby Digital Pro Logic IIx is now a surround mode selection available by the HTR 2's and T 773's front panel
button, SURROUND MODE.
