ATTENTION!

Please make all connections to your T 743 receiver with the unit powered off or unplugged. (It is also advisable to power-down or unplug all associated components while making or breaking any signal or AC power connections.)

1FM & AM ANTENNA: The supplied wire “dipole” FM antenna will connect to the FM connector using the supplied “balun” adapter. It will usually work best when mounted on a vertical surface such as a wall, with arms fully outstretched forming a horizontal “T” perpendicular to the origin point of the signal. Experiment with placement and orientation of to yield the clearest sound and lowest background noise. In areas of difficult FM reception an external FM antenna can yield dramatic gains in quality; consult your NAD audio specialist or a professional antenna installer.

The AM loop antenna supplied with the T 743 (or a suitable replacement) is required for AM reception. Open the clip terminal lever, insert the wire and close, ensuring that the lever locks the wire in place. Testing different positions for the antenna may improve reception; vertical orientation will usually produce the best results. Antenna proximity to large metal objects (appliances; radiators) may impair reception, as will attempts to lengthen the wire to the loop.

NOTE: An external AM antenna can improve long-distance reception substantially; consult your NAD audio specialist or a professional antenna installer. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna.

2MONITOR OUT: Connect to video input of the monitor/television, using quality dual-RCA and/or S-Video cables designed for video signals. In general, the S-Video connection is superior and should be used if your TV/monitor provides the corresponding input.

NOTE: The T 743 “transcodes” S-Video to composite-video signals, so that S-Video signals connected to the DVD, SAT, VCR, and VIDEO 4-6 inputs will be present at both the S-Video and composite MONITOR OUT jacks when any of these inputs is selected. This provides the convenience of requiring only a single video connection (usually S-Video) between the T 743 and the TV/monitor.

3CD: Connect the analog stereo audio output from a CD player or other line-level audio source to this input.

4DIGITAL 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.

5SOFT CLIPPING: Enables NAD’s proprietary Soft Clipping circuitry on all channels. Soft Clipping gently limits the output of the T 743 to minimize audible distortion, even should the receiver be over-driven.

NOTE: Soft Clipping may simply be left on at all times to reduce the likelihood of audible distortion from excessive volume settings. However, for critical listening, to preserve optimum dynamics you may wish to defeat it by setting this switch off.

6IR: These mini-jacks accept and output remote-control codes in electrical format, using industry-standard protocols, for use with “IR-repeater” and multi-room systems and related technologies. Consult your NAD audio specialist for more information.

7+12V TRIGGER IN/OUT:

TRIGGER IN connects to the 12-volt trigger outputs of compatible components such as power controllers and home automation devices. The TRIGGER AUTO/OFF switch selects the 12V Trigger Input and disables the remote and front panel ON function.

TRIGGER OUT connects to 12V Input of compatible devices (such as amplifiers and projector-lifts) to automate turn on/off or activation. See “Trigger Setup”, your NAD audio specialist also can provide more information on using the T 743’s triggers.

AUTO TRIGGER SWITCH when in the AUTO position, forces the T 743 to turn on only when a trigger signal is present at the trigger input. When in the OFF position, the trigger inputs are disabled.
