ABOUT THE T 773 Though the T 773 is among the most technically sophisticated A/V Receiver, 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: ENGLISH • The T 773 uses NAD’s proprietary Power Drive™ amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker.
ABOUT THE T 773 UPGRADABILITY The T 773 A/V Receiver permits flexible system growth via individually accessible pre-out and main-in jacks for all channels. We have made the more likely scenario of software upgrades easy to accomplish via the high speed RS-232 port on the rear panel of the T 773. Owners who register their T 773 on our international web site www.NADelectronics.com will be advised of updates.
QUICKSTART In case you simply cannot wait to experience the performance of your new NAD T 773 A/V Receiver, we provide the following “Quickstart” instructions to get you underway. The steps below connect your DVD player to the T 773’s DVD input; be sure to read “Input Setup”, below. PLA Y A DVD MOVIE PLAY ENGLISH • Connect the T 773’s composite video or S-Video MONITOR OUT jack to your TV/monitor’s corresponding input (Cables not supplied).

REAR PANEL 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.
SETTING UP THE T 773 GETTING ST AR TED STAR ARTED Before you make the first connection to your T 773, 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.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT The T 773 A/V 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-to-day operation), so be sure to connect the monitor/TV before proceeding with setup.
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.
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.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT CREATING AND USING PRESETS The T 773’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 773 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.
USING THE T 773 You may operate the T 773 A/V 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.
USING THE T 773 SELECTING THE RADIO Press the AM/FM key on the T 773 front panel, the HTR 2’s orange [TUNER] (the numeric 9 key), or the yellow [AM] and [FM] keys to select the A/V 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.
USING THE T 773 ABOUT DTS AND DOLBY DIGIT AL SURROUND MODES DIGITAL DTS DIGIT AL SURROUND DIGITAL ENGLISH The Digital Theater System Digital Surround (simply called DTS) is a multi-channel 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.
USING THE T 773 DOLBY PRO LOGIC Dolby Pro Logic is a surround format consisting of four channels (front right, centre, front left and surround. Media sources with the “Dolby Surround” feature produce a theatre–like surround sound. The surround channel is monophonic, but it is reproduced in both surround speakers. DOLBY PRO LOGIC II SURROUND This mode applies conventional 2-channel signals such as digital PCM or analog stereo signals as well as Dolby Surround signals, etc.
USING THE T 773 • Enhanced-Stereo 2 (ST2) All recordings reproduced in stereo via the surround speakers only (plus subwoofer, if any), assuming these are configured in the current . ST2 can prove useful in certain late-night or very low-volume listening situations. • • • • • • ENGLISH The following Surround Sound Modes require a specially encoded signal that must be present in digital format to be decoded by the T 773.
USING THE T 773 ADJUSTING LISTENING MODES Several of the T 773’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 773’s VFL Display. One can also select variations using the HTR 2 [ / ] cursor keys on the line of the OSD.
USING THE T 773 SURROUND SOUND CHANNEL CHART ENGLISH The following table shows which channels work when a particular mode is selected: X= Speaker channel available. X* X** Only if selected in Speaker Setup Menu. Must be selected to access this Mode. X*** LFE Must have both Back Surround speakers selected. Low Frequency Effects are not present on all films. Finally, make sure all the speaker terminals are tightened particularly if using banana plugs.
USING THE HTR 2 REMOTE CONTROL SPECIFICA TIONS SPECIFICATIONS • • • • • • • • Controls up to 8 devices. 44 function keys. Learns up to 352 commands. Records up to 44 macros with a maximum of 64 commands each. Configurable punch-through. Key illumination with programmable timeout. Upgradable. Contains pre-programmed library of NAD remote codes. The NAD HTR 2 is ready to operate the T 773 A/V Receiver right out of the box, but it is really eight remotes in one.
USING THE HTR 2 REMOTE CONTROL PUNCH-THROUGH The HTR 2’s “punch-through” function allows you to retain a function key from one Device Select “page” on another, so that, for example, the AMP [SURR MODE] function might still control the T 773 when the DVD Device Selector page is active ENGLISH NOTE: The HTR 2’s [VOL] keys are pre-programmed as “punched-through” for all Device Select pages: [VOL] will operate the T 773’s master-volume regardless of the currently selected device. The [SURR.
USING THE HTR 2 REMOTE CONTROL KEY -ILLUMINA TION TIMEOUT KEY-ILLUMINA -ILLUMINATION The HTR 2’s key-illumination can be set to remain lit for 0-9 seconds. The default value is 2 seconds. To set the illumination timeout, simultaneously press-and-hold for 3 seconds both the HTR 2’s [DISP] and the [0-9] key, with the digit corresponding to the desired timeout duration; the Learn LED will flash twice to confirm the new setting. When set to zero, the illumination will not turn on at all.
USING THE HTR 2 REMOTE CONTROL Search Mode If none of the codes from the table, when entered, turns on the component, and if you are quite sure you have followed the above procedure completely and carefully, you may want to try the “search” method as follows: ENGLISH Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired Device Selector key and the [A/V PRESET] key, until the Learn LED turns green.
