NOTE: The T 773’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 773 does not display its
on-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection between
the T 773 and the monitor/TV, and select it for menu display.
9 DIGITAL IN OPT 1-2; COAX 3-6: Connect to the coaxial S/PDIF-format digital outputs of sources such as CD or DVD players, HDTV or satellite
tuners, or other components; connect DIGITAL IN OPT1-2 to optical S/PDIF-format digital outputs.
DIGITAL OUT: Connect the optical and/or coaxial DIGITAL OUT ports to the corresponding S/PDIF digital input of a recording component such as
a CD recorder, DAT deck, or computer soundcard. See "Setting Up the T 773", below.
10 RS-232: Connect this interface via RS-232 serial cable (not supplied) to any Windows® compatible PC to allow remote control of the T 773 through
NAD’s proprietary PC software. See your NAD audio specialist for more information.
11 POWER: Press in to switch the A/V Receiver to standby mode. Pressing POWER again turns the unit OFF, recommended if you do not plan to use
your A/V Receiver for an extended period of time. It is usual (and perfectly acceptable) to leave the T 773 in Standby mode in between normal
viewing and listening sessions.
12 SWITCHED AC OUTLET: This convenience jack can supply switched power to another component or accessory. It is powered on and off by the
front panel POWER SWITCH (or the HTR2’s [On] and [Off] keys).
NOTE: The total draw of all devices connected to this jack must not exceed 120 watts.
13 AC POWER INLET: Connect to the supplied IEC-standard removable AC power cord or a compatible cord.
14 SPEAKERS A & B: Connect the left and right front, centre, left and right surround, and surround back speaker outputs to the corresponding
loudspeakers. Each output’s “+” (red) terminal and “-“ (black) terminal must be connected to the corresponding “+” and “-“ terminals of the
loudspeaker. Use extra care to ensure that no stray wires or strands cross between posts or terminals at either end.
Connect Speakers B left and right speaker outputs to the corresponding remote loudspeakers. When speakers B are activated the output is taken
from the front left and right channels and any signal source is converted “downmixed” to stereo as indicated in the florescent display.
NOTE: Use stranded wire of at least 16 gauge (AWG); specialized speaker cable may be valuable (consult your NAD audio specialist). Connections
to the T 773 can be made with banana plugs (US model only), or using bare wire, or pins, by loosening the terminal’s plastic nut, making a clean,
neat connection, and re-tightening carefully (use the transverse hole through the post for bare-wire or pin connections). To minimize the danger
of short-circuits, ensure that only 1/2-inch of exposed wire or pin is employed in connecting.
NOTE: This unit is designed to produce optimum sound quality when connected to speakers with impedances within the A/V Receiver’s operating
range. Please check front, center, and surround speakers are rated to be 4
Ω min. per speaker.
IMPORTANT NOTE: For optimum surround performance, the T 773 speaker settings and levels must be set correctly via the A/V Receiver’s setup
routines; see “Setting Up the T 773”, below.
15 DVD, SAT, VCR, VIDEO 4, VIDEO 5: These comprise the T 773’s principal inputs. Connect S-Video, composite video, and analog stereo audio from
source components such as DVD players and HDTV/satellite tuners (see "Input Setup," below). VCR and VIDEO 4 may be used with recording
components such as videocassette or DVD-recorders; connect the T 773 S-Video/composite video OUT jacks to these components’ record-inputs.
(Note that VCR/VIDEO 4 may freely be used for play-only components, in which case their OUT jacks would remain unconnected.)
16 MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT: The T 773’s 7 built-in power amplifier channels will deliver excellent quality with even very
demanding, low sensitivity home-theatre speaker systems. However, it is also possible to use the T 773 as a pre-amplifier with external power
amplifiers for some or all channels (remove the supplied jumpers) if necessary. Unlike the six full range channels, there is no power amplifier built-
into the T 773 for a subwoofer.
Connect the SW output 1, 2 or both to powered (“active”) subwoofers (or to power amplifier channels driving a passive system).
SURR-BACK-R jack will supply the same signal from the surround-back Left channel if the T 773 is so configured (see “Speaker Setup,” below).
Either one or both channels are available mono or stereo as per “Speaker Setup”. Your NAD audio specialist will be happy to advise you.
NOTE: Never connect the T 773’s speaker outputs and the speaker outputs of an external amplifier to the same speakers.
17 TAPE IN/OUT: Connect the T 773’s TAPE OUT jacks to the stereo analog audio inputs, of an audio recording component such as a cassette deck
or CD recorder, or of an outboard analog audio processor such as a stereo equalizer; connect the A/V Receiver’s TAPE IN jacks to the component’s
corresponding outputs. The signals present at the TAPE IN jacks can be heard by selecting the front panel TAPE MONITOR button, or the HTR 2’s
[Tape] (zero) key.
NOTE: The signal present at the TAPE OUT jacks is determined by the source last selected via the front panel Video or Audio keys (or the HTR
2’s input-select keys).
NOTE: Digital input signals are not available at the analog TAPE OUT jacks; they are only available at the DIGITAL OUT jacks.
18 DISC: Connect the analog stereo audio output from a second CD player or other line-level audio source to this input.
NOTE: Connecting a phonograph turntable to the T 773 requires an outboard magnetic phono-preamp component such as the NAD PP2; you
cannot connect turntable directly to the DISC inputs.
19 7.1 CH. INPUT: Connect to the corresponding analog audio outputs of a multi-channel source component such as a DVD-Audio or multichannel-
SACD player, or external multi-channel decoder. Typically, these sources will produce 5.1-channel output, in which case the SURROUND BACK
jacks are left unconnected. The signals present at these jacks may be heard by selecting the front-panel EXT. 7.1 key or the HTR 2’s [Ext 7.1/
5.1] button. See “Selecting Sources," below.
NOTE: There is no bass-management or other processing (other than master-volume control) available to this 7.1 CH. INPUT. While the multi-
channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 773’s own Dolby Digital and DTS decoding and digital-
analog converters, via a digital connection, will usually produce superior results.
