ABOUT THE T 743 Though the T 743 is among the most technically sophisticated A/V receivers, we worked hard to make it one of the most musically transparent home-theater components available as well; this is what we mean by NAD’s “Music First” design philosophy. Here are just a few examples: • NAD’s exclusive Soft Clipping™ circuitry further enhances sound quality and dynamic potential.
PAGE 8
ABOUT THE T 743 UPGRADABILITY The T 743 receiver permits flexible system growth via individually accessible pre-out and main-in jacks for three channels, enabling external amplifiers to be used for any of these while still maintaining utility of the receiver’s on-board power-amplifier channels for additional channels, remote-room links, or any other suitable purpose.

SETTING UP THE T 743 GETTING ST AR TED STAR ARTED Before you make the first connection to your T 743, you should have the arrangement of your listening room/ home theater components and furniture mapped out, at least initially. Unfortunately, a discussion of the vital questions of loudspeaker placement and listening/viewing positions is beyond our scope here.
PAGE 15
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT The T 743 receiver employs a simple, self-explanatory system of on-screen display "menus" that will appear on the connected video monitor/TV. These are required during the setup process (and are useful in day-today operation), so be sure to connect the monitor/TV before proceeding with setup.
PAGE 16
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT SPEAKER SETUP Every surround-sound system requires "bass-management" to direct low-frequency content from any or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that you correctly identify your speakers' capabilities. We use the terms "Small" and "Large" (and "Off"), but note that physical size may be irrelevant.
PAGE 17
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT CHANNEL-BALANCE (TEST) SETUP ENGLISH Adjusting the relative balance of your system's loudspeakers ensures that surround-sound recordings, whether music or film, will present the balance of effects, music, and dialog that the artists intended.
PAGE 18
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT CREATING AND USING PRESETS The T 743’s simple but powerfully flexible system of “Presets” allows you to customize virtually every aspect of your audio-video playback, and recall them with a single key-press. Every parameter of T 743 operation that is available from the main menu — input settings, level settings, delay settings, speaker settings, and listening mode selection and adjustments — is stored, together, as a single Preset.
PAGE 19
USING THE T 743 You may operate the T 743 receiver from its front panel or via the HTR 2 remote control. Since the remote will be the primary controller for most cases, we will focus on remote-controlled operations. Be sure also to read the section, "Front Panel" above. SELECTING SOURCES ENGLISH With the HTR 2’s remote's [Amp] device selected, the remote’s numeric-key section directly selects the receiver’s inputs, plus the internal tuner ([Tuner), Tape Monitor ([Tape]), and multichannel input ([Ext. 7.
PAGE 20
USING THE T 743 SELECTING THE RADIO Press the AM/FM key on the T 743 front panel, the HTR 2’s orange [TUNER] (the numeric 9 key), or the yellow [AM] and [FM] keys to select the receiver’s radio mode. Each subsequent press of either key will toggle the unit between its FM and AM bands. TUNING ST ATIONS STA Press SEARCH on the front panel momentarily to step up or down between FM or AM frequencies.
PAGE 21
USING THE T 743 ABOUT DTS AND DOLBY DIGIT AL SURROUND MODES DIGITAL AL SURROUND DIGITAL DTS DIGIT ENGLISH The Digital Theater System Digital Surround (simply called DTS) is a multichannel digital signal format that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are 5.1 channel media formats, discs bearing the “DTS” symbol are thought to provide better sound quality due to the lower audio compression required.
PAGE 22
USING THE T 743 ABOUT THE T 743'S LISTENING MODES The T 743 receiver offers nine distinct listening modes, tailored for different types of recordings or program material. The table below lists which modes are available to what input signals. With a two-channel (STEREO) source the following listening modes can be selected: • Stereo • Downmix All output is directed to the left/right-front channels; low frequencies are directed to the subwoofer if one is present in the Speaker settings.
PAGE 23
USING THE T 743 The following Surround Sound Modes require a specially encoded signal that must be present in digital format to be decoded by the T 743. These modes are automatically switched on when the appropriate data stream is detected selected in the setup menu of the source media.
PAGE 24
USING THE T 743 ADJUSTING LISTENING MODES Several of the T 743’s listening modes have one or more selectable variations and adjustable parameters you can modify to suit you system, the recording, or your personal preferences. Use the HTR 2 remote's [Surr. Mode] key, or the front panel SURROUND MODE key, to select the Listening Mode you wish to display and listen to; this will display on the T 743’s VFL Display. One can also select variations using the HTR 2 [ / ] cursor keys on the line of the OSD.
PAGE 25
USING THE T 743 SURROUND SOUND CHANNEL CHART ENGLISH The following table shows which channels work when a particular mode is selected: X= X* Speaker channel available. Only if selected in Speaker Setup Menu. LFE Low Frequency Effects are not present on all films. Finally, make sure all the speaker terminals are tightened particularly if using banana plugs. ADJUSTING CHANNEL LEVELS “ON THE FL Y” FLY” You can make changes to the relative levels of center, surround, and subwoofer outputs.
