GETTING THE MOST FROM THE NAD T 752 Thank you for choosing NAD. ENGLISH The T 752 A/V Surround Sound Receiver is a technologically advanced and highly capable product — yet we have invested great effort in making it simple and easy to use. The T 752 delivers a range of genuinely useful options for surround sound and stereo listening alike, using powerful digital signal processing and superbly accurate digital-audio circuitry.
UNPACKING AND SETUP WHA T’S IN THE BOX WHAT’S Packed with your T 752 receiver you will find: • • • • • An AM loop antenna A FM ribbon-wire antenna with balun A removable AC cable (if you wish, any IEC-standard AC cable of suitable wattage may be substituted). The HTR 2 remote control with 4 (four) AAA batteries. This owner’s manual. Save the packaging Please save the box and all of the packaging in which your T 752 arrived.
ABOUT THE T 752 Though the T 752 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: ENGLISH • The T 752 uses NAD’s proprietary Power Drive™ amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker.
ABOUT THE T 752 UPGRADABILITY The T 752 receiver permits flexible system growth via individually accessible pre-out and main-in jacks for all three front 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. Of course, the T 752’s Surround Back channel outputs let a system grow from 5.1 to 6.1 or 7.
QUICKSTART In case you simply cannot wait to experience the performance of your new NAD T 752 receiver, we provide the following “Quickstart” instructions to get you underway. The steps below connect your DVD player to the T 752’s DVD input; be sure to read “Input Setup”, below. PLA Y A DVD MOVIE PLAY ENGLISH • Connect the T 752’s composite video or S-Video MONITOR OUT jack to your TV/monitor’s corresponding input.

Pressing any other front-panel key, or the HTR 2 remote’s [ON] button, will switch the receiver on, making it operational, changing the amber Standby indicator to green and illuminating the VFL display.
FRONT PANEL 11 VIDEO: Use to select a video input along with its assigned audio and digital inputs (see “Input Setup,” below). Press repeatedly to step through the T 752’s Video inputs. 12 TAPE MONITOR: Press to engage the Tape Monitor loop. The signal present at the rear-panel TAPE MONITOR IN jacks will be heard. Press again to release and return to the previously selected input. NOTE: Selecting any other input selection while Tape Monitor is engaged automatically releases it.
REAR PANEL 2 4 3 5 7 6 8 1 16 9 10 15 14 13 12 11 ATTENTION! Please make all connections to your T 752 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.) 1 FM & AM ANTENNA: The supplied wire “dipole” FM antenna will connect to the FM connector using the supplied “balun” adapter.
5 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 752 requires an outboard magnetic phono-preamp component such as the NAD PP1; you cannot connect turntable directly to the DISC inputs. 6 IR: 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.
SETTING UP THE T 752 GETTING ST AR TED STAR ARTED Before you make the first connection to your T 752, 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 752 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.
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 "None"), but note that physical size may be irrelevant.
ABOUT THE ON-SCREEN DISPLAYS (OSD) AND FRONT-PANEL READOUT As the test signal cycles around the speakers, the OSD (and the VFL front panel display) will highlight the currently playing channel. Now use the remote's [< / >] keys to adjust the loudness of the noise output from the currently playing channel to the required level (it’s usually simplest to begin with the left-front). The "level offset" reading on the right will change by 1 dB increments; ±12 dB adjustment is available.
USING THE T 752 You may operate the T 752 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 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. 7.1/ 5.
USING THE T 752 ABOUT ANTENNAS ENGLISH The supplied ribbon-wire FM antenna can be connected to the rear-panel FM-antenna input using the ‘balun’ included adapter, and should be fully extended to form a “T”. This folded-dipole antenna will usually work best oriented vertically, with the arms of its “T” full outstretched and arranged perpendicular to the origin of the desired broadcast.
USING THE T 752 ABOUT THE T 752'S LISTENING MODES The T 752 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.
USING THE T 752 • • • • Dolby Digital Dolby Digital EX DTS DTS ES 6.1 ENGLISH Digital recordings in Dolby Digital or DTS formats are reproduced via the channels employed in the original recording (up to the maximum channels present in the current setup). NOTE: The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output.
USING THE T 752 ADJUSTING LISTENING MODES Several of the T 752’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 T752’s VFL Display.
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. ENGLISH • • • • • • • • The NAD HTR 2 is ready to operate the T 752 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 752 when the DVD Device Selector page is active NOTE: The HTR 2’s [VOL] keys are pre-programmed as “punched-through” for all Device Select pages: [VOL] will operate the T 752’s master-volume regardless of the currently selected device. The [SURR.
USING THE HTR 2 REMOTE CONTROL NOTE: When a macro executes, a 1 second delay is automatically inserted between its commands. If you need more than a 1 second delay between particular commands—for example, to permit a component to power up completely—you can record “empty” steps into the macro by changing Device Selector “pages” without entering actual command functions. ENGLISH KEY -ILLUMINA TION TIMEOUT KEY-ILLUMINA -ILLUMINATION The HTR 2’s key-illumination can be set to remain lit for 0-9 seconds.
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: 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.
