COMPONENT VIDEO IN 1-2; OUT

: Connect the COMPONENT VIDEO IN 1, and 2 inputs to component-video outputs from compatible source

components, typically a DVD player and terrestrial or satellite HDTV tuner. Connect the T 743 COMPONENT VIDEO OUT to the component-video
input of a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Cr/Cb jacks (some source and TV components label
these Y/ Pb/Pr) to the corresponding sources/inputs; do not rely purely on the colour-coding of the jacks, which may not always be consistent
among brands. The routing of the component-video inputs follows the S-Video/composite, but is default as: COMPONENT VIDEO IN 1 is routed
to the COMPONENT VIDEO OUT jacks when the DVD input is selected; COMPONENT VIDEO IN 2 is selected when the SAT input is active; the audio
and digital inputs assigned to DVD, and SAT will be used (see also, "Input Setup”).

NOTE

: The T 743’s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 743 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 743 and the monitor/TV, and select it for menu display.

AC POWER CORD

: After you have completed all connections to the amplifier, plug the AC line cord into a “live” wall socket.

10 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 743 in Standby mode in between normal
viewing and listening sessions.

11

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 

STANDBY 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.

12 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 743 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 receiver’s operating

range. Please check front, center, and surround speakers are rated to be 4

 min. per speaker.

IMPORTANT NOTE

: For optimum surround performance, the T 743 speaker settings and levels must be set correctly via the receiver’s setup

routines; see “Setting Up the T 743”.

13

DVD, SAT, VCR, VIDEO 4, VIDEO 5

: These comprise the T 743’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 743 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.)

14 MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT

: The T 743’s five 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 743 as a pre-amplifier with external power
amplifiers for some of all channels (remove the supplied jumpers) if necessary. Unlike the six full range channels, there is no power amplifier built-
into the T 743 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 743 is so configured (see “Speaker Setup,” below).
Either one or both channels are available mono or stereo as per “Speaker Setup”. Connect to one or two channels of an appropriate external
power amplifier or other amplified component to furnish amplification for one or two surround back speakers. Your NAD audio specialist will be
happy to advise you.

NOTE

: Never connect the T 743’s speaker outputs and the speaker outputs of an external amplifier to the same speakers.

15 TAPE IN/OUT

: Connect the T 743’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 receiver’s TAPE IN jacks to the component’s
corresponding outputs.

NOTE

: Digital input signals are not available at the analog TAPE OUT jacks.

16 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 743 requires an outboard magnetic phono-preamp component such as the NAD PP2; you

cannot connect turntable directly to the DISC inputs.

17

5.1 CH. INPUT

: Connect to the corresponding analog audio outputs of a multichannel source component such as a DVD-Audio or multichannel-

SACD player, or external multichannel 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 soure Down and Up key or the HTR 2’s [Ext
5.1] button. See “Selecting Sources," below.

NOTE:

 There is no bass-management or other processing (other than master-volume control) available to this 5.1 CH. INPUT.  While the multi-

channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 743’s own Dolby Digital and DTS decoding and digital-
analog converters, via a digital connection, will usually produce superior results.
