Thank you for choosing NAD: The T 754 AW 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 754 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. However, we have also been careful to ensure that the receiver is 2s musically transparent and spatially accurate as possible, incorporating much of what we‘ve learned from à quarter-centuryS experience designing audio and home-theater components. As with all our products, NADS “Music First” design philosophy guided the T 754 design, such that it can confidently promise you both state-of-the-art surround home-theater and audiophile-quality music listening for years to come We encourage you to take a few minutes now to read right through this manual. Investing a little time here at the outset might save you a good deal of time later, and is by far the best way to ensure that you make the most of your investment in the NAD T 754, and get the most from this powerful and flexible home- theater component One more thing: We urge you to register your T 754 ownership on the NAD Worldwide Web site: <http://NADelectronies.com/w/Registration.html > For warranty information contact your local distributor.

Packed with your T 754 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. The ZR 2 zone remote control with 3V CR2025 battery. This owners manual Save the packaging Please save the box and all of the packaging in which your T 754 arrived. Should you move or otherwise need to transport your receiver, this is by far the safest container in which to do so. We‘ve seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!

Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide à clear line of sight, within 25 fee meters, between the receivers front panel and your primary listeningwiewing position—this will ensure reliable infrared remote control communications. The T 754 generates à modest amount of heat, but nothing that should trouble adjacent components. It is perfectiy possible to stack the T 754 atop other components, but the reverse usually should be avoided. Nonetheless, it is generally preferable that the T 754 stand alone. It is especially important that sufficient ventilation be provided; if you are contemplating locating the T 754 within a cabinet or other furniture, consult your NAD audiohideo specialist for advice on providing adequate airflow.

Though the T 754 is among the most technically sophisticated AW 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' “Music First” design philosophy. Here are just a few examples The T 754 uses NAD' proprietary Power DriveT" amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker. This uniquely efficient power-supply topol- ogy provides the realworld benefits of high dynamic power that remains uncompromised by low- impedance speakers. The result is dynamic, detailed, “un-receiver-like” sound in stereo and multichannel modes alike. NAD' exclusive Soft Clipping"* circuitry further enhances sound quality and dynamic potential. High-performance components used throughout the receivers analog audio circuits maximize quality from all sources, including muitichannel analog sources such as DVD-Audio and SACD. Preamp output (all channels) and main-amp input jacks make potential expansion as flexible as possible. À Second set of Speaker terminals (Speakers B) for remote listening Second Zone (MULTISOURCE) pre-amp feed with assignable 12 V DC trigger control Gold-surfaced connectors are employed throughout to ensure maximum signal integrity E.A.R.S., MATRIX AND DIGITAL SURROUND A key element of the T 754% unique musical aptitude is NAD' proprietary Enhanced Ambience Recovery System (EARS). In sharp contrast to many “ambience-synthesis” music-surround modes, EARS exploits the T 754% substantial DSP power to route the ambient content that is “encrypted” in virtually all natural- acoustic recordings to the appropriate main, center and surround speakers, without resorting to artificially generated reflections or regeneration. EARS' natural ambience yields a subtle but exceptionally effective surround mode that naturally enhances the spatial presentation in a fashion suitable for serious music listening. The T 754 also incorporates a second proprietary surround mode, Matrix 7.1. This creates à full 6.1/7.1-channel environment from stereo and surround-encoded recordings, oftentimes with extraordinarily good results. Dolby ProLagic Il Music and DTS Neo:6 Music modes can also create enjoyable experience from 2-channel sources On the digital side, the T 754 combines extraordinarily high-speed DSP processing employing one of the most advanced high-speed DSP “engines” available, with fully 24-bit, 96 kHz-sampling-capable D/A converters for all channels. A single, high-precision master clock synchronizes all digital circuits to eliminate the timing errors (“jitter”) that otherwise compromise sonics. The result is legitimately state-of-the-art surround decoding from Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with genuinely superior sound quality in all modes.

Despite the effort NAD has invested in the T 754 receivers sonic performance, we expended no less in making it powerfully easy to use. Its design is uniquely simple for so sophisticated a component, and the HTR 2 universal remote control is equally understandable, as are the T 754% own front-panel and on-screen displays. its simple yet powerful system of “presets” permits you to fine-tune your listening setup for different conditions, sources, or listeners, and to recall these multiple parameters with à single keypress. INTEGRATION The T 754 receiver offers extensive, flexible system-integration options through its configurable DC trigger outputs and input, and its standard-protocol IR communications links. The DC trigger outputs can be assigned to either Local and/or Zone locations SECOND ZONE (MULTISOURCE) The T 754 receiver is equipped with a second Zone control of the Pre-amp level audio outputs from the second Zone remote control ZR 2. Completes access to volume, On/Off, and all audio analog/digital inputs, including the local input is available

ABOUT THET 75 UPGRADABILITY The T 754 receiver permis 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 on-board power-amplifier channels for additional channels, remote-100m links, or any other suitable purpose. Of course, the T 754’ Surround Back channel outputs let a system grow from 6.1 to 7.1 channels, simply by adding a 1- or 2-channel external amplifier. See “Rear Panel (Audio Pre-Out)"

ABOUT THE HTR 2 SYSTEM REMOTE CONTROL

Packed with your T 754 is the NAD HTR 2 remote control, a full-system remote especially designed to be easy to use and easy to understand. Be sure to read the section “Using the HTR 2 Remote Control”, to familiarize yourself with the remote’s layout and operations before proceeding to setup your AW receive. Chances are, you will want to use your HTR 2 as your primary way to command your entire A-V system. The HTR 2 can be employed to operate additional NAD or other-brand components such as à DVD/CD player, television, satellite/HDTV tuner, VCR, or virtually anything else that operates via standard infrared remote control.

QUICKSTART In case you simply cannot wait to experience the performance of your new NAD T 754 receiver, we provide the following “Quickstart” instructions to get you underway. The steps below connect your DVD player ta the T 754% DVD input; be sure to read “Input Setup”, below

Press in the main power switch (black pushbutton) on the T 7545 rear panel (this puts the T 754 into STANDBY mode and illuminates an amber LED to indicate it is ready to receive remote commands), then use the HTR 2's [ON] key to power up the receiver. Be sure the TV/monitor is powered up, with the correct input selected Start playback of the DVD player. Press the HTR 2 remote’s [Amp] Device Selector key, and then its (red) DVD/numeric 1 key to select the DVD input. You should hear multichannel or stereo sound, and see an image on the TV/monitar. (If one or the other fails to appear, you may need to use the receivers on-screen menu system to check assignment of audio, video, and digital inputs; see “Setting Up the T 754.) Enjoy the movie or music, but be sure to set aside time to read this manual thoroughly, and to set up, calibrate, and configure your T 754 carefully and completely.

STANDBY SWITCH: Pressing this 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. STANDBY LED: Illuminates amber when the T 754 is in Standby mode; green when it is powered on; and flashes momentaril to indicate infrared commandé received from the HTR 2 remote. Protection Mode is indicated by a red illumination, and indicates that there is a problem with your set- up or the unit itself. When the fault is removed, normal operation can be resumed (this may require turning the unit off and on again). This indicator will be steadily dark only when the main POWER switch (REAR PANEL No.9) is switched off (or the receiver is unplugged from the AC supply). AM/FM: Press to toggle between the tuners AM and FM bands FM MUTE/MODE: In the normal Mute position, only the stations with a strong signal can be listened to, and the noise between stations is muted Pressing the [FM Mute/Mode] button allows distant (and potentially noisÿ) stations to be received. (See “Listening to Radio”) DISPLAY: Press 1o display the channel mode of the currently selected source (other than the internal AM/FM tuner), in the format “front/rear/LFE." For example, a Dolby Digital or DTS 5.1-channel source will display 3/2.1. Note that the display shows signal channels, not speakers; for example, à 2-channel analog or digital source (whether stereo or surround-encoded) will show 2/0.0, even though the receivers <Speaker Settings> may indeed be set up to use the subwoofer with all sources, and the current Listening Mode may employ center and surround speakers When the AM/FM tuner is the selected input, sequentially pressing DISPLAY shows the currently tuned stations RDS data, toggling between the current stations Radio Text and Station Name displays (see Listening to Radio, below) MEMORY: Use to store tuned stations to the T 754' 40 preset-memory locations.

LEVELS: Press repeatedly to select the channel, and then use the VOLUME(SETUP) knob to adjust the levels of the T 754 7 channels /pairs in turn: front-left, -center, -right; surround; surround back; subwoofer. The selected channel appears on the VFL and on-screen displays; use the VOLUME(SETUP) knob to adjust its level relative to the others over a range of +12 dB. Channel levels may also be adjusted via the on-screen menus; see *’Adjusting Channel Levels,” below. NOTE: The HTR 2 remotes [Surr.], [Center], and [Sub] 4 / » keys provide direct access to those channels’ relative levels, however in this case the level changes are only temporary and are not saved in memory: TONE DEFEAT: Press to disable the tone controls; press again to re-enable them for instance, to compare a tone setting to unmodified sound NOTE: While TONE DEFEAT is engaged, the TONE CONTROLS key will have no effect. TONE CONTROLS: Press to adjust treble using the VOLUME (SETUP) knob over a +10 dB range: press again to adjust bass, and a third time to exit tone-control adjustment. SPEAKERS À & B: Press either speaker À or B or both to select the set of speakers you wish to listen to. The Speakers A are the main set of 6 multi- channel front and surround speakers. The Speaker B are an auxiliary set for remote locations such as other rooms of your home. For Speaker B selection all surround sound sources are downmixed to stereo as shown in the florescent display. VIDEO 6 INPUT: Use these convenience jacks for occasional sources, such as à camcorder, portable MP3 or tape player, or à video game console, or any other analog audio, or composite or S-Video video source. Select the Video 6 input using the HTR 2 remote, or the front-panel VIDEO 6 key. PHONES: Accepts stereo headphone using a standard 1/4-inch stereo phone plug (use a suitable adapter for headphones equipped with a smaller plug); set the Listening Mode to “Stereo.” NOTE: For headphone listening the front leftright speakers must be set to “Large” on the OSD's Speaker Settings page, otherwise headphone bass response will be restricted NOTE: Plugging in headphones will automatically switch the T 754 to “Stereo” mode

ATTENTION! Please make all connections to your T 754 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. 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 à professional antenna installer. The AM loop antenna supplied with the T 754 (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 substantiallÿ; consult your NAD audio specialist or à professional antenna installer. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna: 2 SOFT CLIPPING: Enables NADS proprietary Soft Clipping circuitry on all channels. Soft Clipping gently limits the output of the T 754 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. 3 MONITOR 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. 4 CD: Connect the analog stereo audio output from a CD player or other line-level audio source to this input. 5 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. Consult your NAD audio specialist for more information. 6 +12VTRIGGERIN/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 projectr-lifts) to automate turn on/off or activation. See Trigger Setup”, your NAD audio specialist also can provide more information on using the T 7545 triggers. AUTO TRIGGER SWITCH when in the AUTO position, forces the T 754 to turn on only when a trigger signal is present at the trigger input. When in the OFF position, the trigger inputs are disabled. 7 COMPONENT VIDEO IN 1-2; OUT: Connect the COMPONENT VIDEO IN 1, and 2 inputs to component-video outputs from compatible source components, typically à DVD player and terrestrial or satellite HDTV tuner. Connect the T 754 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; da not rely purely on the colour-coding of the jacks, which may not always be consistent among brands. The routing of the companent-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 12 8SSigned to DVD, and SAT will be used (see also, "Input Setup”)

REAR PANEL NOTE: The T 7545 component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 754 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 754 and the monitor/TV, and select it for menu display. DIGITAL 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. DIGITAL OUT: Connect the optical and/or coaxial DIGITAL OUT ports to the corresponding S/PDIF digital input of a recording component such as à CD recorder, DAT deck, or computer soundcard. See "Setting Up the T 754" POWER: Press in to switch the AI Receiver to standby mode. Pressing POWER again turns the unit OFF, recommended if you do not plan to use your AN Receiver for an extended period of time. It is usual (and perfectiy acceptable) to leave the T 754 in Standby mode in between normal viewing and listening sessions. 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 POWER SWITCH (or the HTR2S [On] and [Off] keys) NOTE: The total draw of all devices connected to this jack must not exceed 120 watts AC POWER INLET: Connect to the supplied IEC-standard removable AC power cord or a compatible cord SPEAKERS À & B: Connect the left and right front, centre, left and right surround, and surround back speaker autputs to the corresponding loudspeakers. Each output “+” (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 754 can be made with banana plugs (US model only), or using bare wire, or pins, by loosening the terminalS 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-cireuits, 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 receivers operating range. Please check front, center, and surround speakers are rated to be 4Q min. per speaker. IMPORTANT NOTE: For optimum surround performance, the T 754 speaker settings and levels must be set correctiy via the receiver's setup routines; see "Setting Up the T 754" DVD, SAT, VCR, VIDEO 4, VIDEO 5: These comprise the T 7545 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 754 S-Video/composite video OUT jacks to these components’ record-inputs. {Note that VCR/VIDEO 4 may freely be used for play-onlÿ components, in which case their OUT jacks would remain unconnected ) MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT: The T 7545 six 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 754 as à pre-amplifier with external power amplifiers for some or all channels (remove the supplied jumpers) if necessary. Unlike the six full range channels, there is no power amplifier built- into the T 754 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 754 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 754% speaker outputs and the speaker outputs of an external amplifier to the same speakers. TAPE IN/OUT: Connect the T 754 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 à stereo equalizer; connect the receiver TAPE IN jacks to the components corresponding autputs. NOTE: Digital input signals are not available at the analog TAPE OUT jacks. MS OUT (MULTISOURCE OUT): Connect this pre-amp outputs to other zones using high-quelity patch cables to reduce noise pickup over long distance runs. 7.1 CH. INPUT: Connect to the corresponding analog audio outputs of a multichannel source component such as à DVD-Audio or multichannel- SACD player, or external multichannel decoder. Typicall, 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 EXT. 7.1 key or the HTR 25 [Ext 7.1/5.1] button. See “Selecting Sources" NOTE: There is no bass-management or other processing (other than master-volume control) available to this 7.1 CH. INPUT. While the multi- channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 754'5 own Dolby Digital and DTS decoding and digital- analog converters, via a digital connection, will usually produce superior results.

GETTING STARTED Before you make the first connection to your T 754, you should have the arrangement of your listening room/ home theater components and furniture mapped out, at least initial. Unfortunately, a discussion of the vital questions of loudspeaker placement and listeninghiewing positions is beyond our scope here. Suffice it to say that these two questions will influence your system's ultimate performance every bit as powerfully as your selection of electronics and speakers. Your NAD audio specialist dealer will be happy to advise you, and Lo recommend reference materials. NOTE: You will need the HTR 2 remote handset to configure your T 754. See “Using the HTR 2 Remote”, below

DEALING WITH HUM AND NOISE

Hum and noise sometimes prove a challenge in complex, multichannel audio systems. Note these consider- tions to help prevent hum and noise problems. Power all your system's audio component from AC outlets originating from the same circuit of your house wiring. As far as possible, power all audio components from the same outlet, or adjacent outlets on the same circuit. t may be useful to power video displays (and computers!) from outlets on another circuit, especially if that circuit is supplied from the other “leg” of the house wiring, Do not bundie analog audio cables with AC power cables, or with coaxial digital-audio cables. It is best if they cross at right angles if they must be in close proximity. Employ high-quality, well-shielded audio cable throughout, and ensure that all connections are secure A pencil-eraser can be used to burnish copper- and gold-plated contacts to ensure good, low-resistance contact; specialized contact-cleaners can also be useful. Avoid unnecessary unplugging and re-plugging, since the gold (or copper) contact plating of typical cable connectors, even very high-quality ones, is very thin and easily worn Track down hum/noise problems one component at à time, working backwards from the receiver. That is Connect the speakers to the receiver only, and check for hum. Then connect one component only (a CD player, for example) alone, with no other components connected and check for hum. Connect additional components, one at à time, to the receiver and check for hum. At each stage, if hum/noise appears, examine the audio cabling and AC-power routing of the new component. In some cases, moving the new components AC cord to a different outlet, or installing a ground-lft (3-to-2-prong adapter) on its power cord, will eliminate the hum

The T 754 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. NOTE: The on-screen displays are carried on both the S-Video and composite MONITOR OUT jacks, but are not incorporated into the component-video output

Press any of the HTR 2 remote's central cursor keys ([ 4 ], [A], [ 1, [+], and [Enter]) to display the T 754% main <Setup> menu on your video monitor/TV. If the OSD does not appear, check your MONITOR OUT connections NOTE: The OSD does not appear on the T 754's component-video output, nor does it appear on the VIDEO 3 and 4 record-outputs; these are for recording, not monitoring

NAVIGATING THE OSD AND MAKING CHANGES

Use the HTR 2 remote's [ A / + ]keys to move up or down among the Setup menus list of items; use [Enter] to select à menu item, and use [ 4 / } ] to change the parameter-value (setting) of any item. Selecting the <Save and Exit> returns “up” to the <Setup> menu while saving any parameter-value changes to the T 754‘ memory; selecting <Do Not Save and Exit> also returns to the main <Setup> menu, but abandons any changes made on the previous menu. Selecting <Exit> from the main Setup menu exits the OSD altogether, retaining parameter-value changes, if any, made previously. INPUT SETUP The T 754 is equipped with nine configurable and nameable inputs: six audio-video inputs labeled DVD, SAT, VCR, and VIDEO 4-6 (including VIDEO 6 on the front panel), and two audio-only inputs labeled CD and EXT 7.1. These are flexibly configurable and nameable: For each labeled video input-jack position (DVD, SAT, VCR, VIDEO 4-6) as displayed on the <Video In> line of the <input Settings> menu, you may freely assign: an analog audio input selected on the <Audio In> line; and a digital input selected on the <Digital In> line. These will become active whenever that input is selected NOTE: An incoming digital signal present at the assigned digital input will always take precedence over the assigned analog-audio input, even if both are present. The digital signal can be temporarily selected “OFF” using the front panel DIGITAL AUDIO SELECTOR button. INPUT SETTINGS From the main <Setup> menu, select the <input settings> menu item using the HTR 2 remote's [A /+ ], and [Enter] keys. Using the [ / } ] keys select the video input (DVD, SAT, VCR, VIDEO 1-6) you wish to configure. Use the [A /+ ] keys to move to the <Audio In> line, and then use the [ € / à ] keys to select the analog audio input you wish to be linked to that input (usually, this will be the same, Le. “DVD” with “DVD," “Video 4" with “Video 4," and so on). NOTE: I is not necessary to have an analog audio input connected for every video input you employ. In fact, in some cases—for example for à DVD player—it may be preferable to make only a coaxial or optical digital audio link to the T 754 for audio playback. This avoids possible confusion, and ensures that the T 754% high- performance surround and digital audio circuitry will always be employed Now use the [A / + ] keys to move to the <Digital In> line and select the digital input (“Opt 1-2," “Coax 1- 4") you wish linked to that input. If you set <Digital n> to “Off,” no incoming digital signal will be selected by that input. (Set an input <Digital in> to “Off” only if you wish to ensure that that input will not play an incoming digital bitstream, even if one is present.) NOTE: The <Trigger Out:> line of the <input Settings> menu is used to configure the T 754' 12-volt trigger. See “Trigger Setup,” below. The component-video inputs are not configurable. Selecting the DVD input routes the COMPONENT VIDEO IN 1 to the COMPONENT VIDEO OUT jacks; selecting SAT routes COMPONENT VIDEO IN 2 to the COMPO- NENT VIDEO OUT jacks. Note that the OSD does not appear on the component-video output. NOTE THAT: The combination of analog-audio input and digital input assigned above will always be recalled whenever that input is selected via the front-panel VIDEO key, or the HTR 2 remotes input-select keys, or by recalling a Preset: The digital and analog audio inputs assigned to à video input can be overridden by using the front-panel AUDIO and DIGITAL AUDIO SELECTOR keys, however, the assigned input will return whenever that video input is reselected, either via the front panel VIDEO key or using the HTR 2' input-select keys (or à Preset); Any audio input and any digital input may be configured with any video input, and the same analog and/or digital inputs may be assigned to multiple video inputs; The analog audio input selected on the <Audio In> line is also routed to the TAPE OUT jacks NOTE: That signals from digital inputs are not available on the analog TAPE OUT jacks.

INPUT SETTINGS DIGITAL IN

T-PANEL READO 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 correctiy identify your speakers’ capabilities. We use the terms “Small” and “Large” (and “Off"), but note that physical size may be irrelevant. + A “Small* speaker is any model, regardiess of physical size, that lacks significant deep-bass response, that is, below about 80 Hz. + A “Large* speaker is any full-range model, that is, one with deep-bass response +_ An “Off” speaker is one that is not present in your system. For example, you might not have any surround- back speakers installed, in that case, you would set the <Surr Back> setup item to * OFF" Depending on the relationship between speakers, the possible selections for each speaker are as follows Front LR Center Sur. LR Surr. Back Subwoofer LARGE LARGE SMALL LARGE OF LARGE SMALL SMALL OF OF LARGE LARGE SMALL OF eo LARGE SMALL LARGE or

OF OF LARGE LARGE SMALL OF LARGE SMALL SMALL OF OF SMALL SMALL SMALL OF OF OF SMALL SMALL on

OF OF SPEAKER SETTINGS From the OSD's main <Setup> menu select the <Speaker Settings> line using the HTR 2 remote's [A / ], and [Enter] keys. Using the [ 4 / } ] keys, set <Front:> to “Large” or “Small” as your main-front speakers require according to the guidelines noted above. Similarly, set <Center:>, <Surround:>, and <Surr Back:> to “Large,” “Small,” or “None” as your system's loudspeakers require. Set <Sub:> to “On or “Off,” selecting “On” only if you have a subwoofer connected to the T 754's SUB analog output jack NOTE: The Speaker Settings configuration is “global”; that is, it remains in force with all inputs and in all listening modes. However, speaker settings are part of the T 754 Preset system; consequentiy, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require See “Creating and Using Presets,” below NOTE: You can set Subwoofer to "On" even with "Large" front speakers, in which case bass content from any channels set to “Small” will be routed to both the subwoofer and to the front speakers; LFE-channel signal will pass only to the sub. in most subwoofer-equipped systems, setting front speakers to *Small* is usually the better option. From the OSD's main <Setup> menu select <Advanced Options> line using the HTR 2 remote's [A /+ ], and [Enter] keys. Using the [ 4 / ] keys select main and zone listening for 5.1/2.0 or 7.1/OFF. NOTE: lf 7.1 input is selected then the zone output is switched off LISTENING MODE From the OSD main <Setup> menu select the <Listening Mode> line using the HTR 2 remote's [A /v ], and Enter] keys. Using the [A / ] and [ 4 / P ] keys you can select mode variations, and adjust various parameters, depending on the current Listening Mode. For more information, see “About the T 754 Listening Modes, ” below NOTE: Listening Mode is part of the T 754% Preset system. See “Creating and Using Presets,” below; NOTE: The Listening Mode used the last time a given input was selected will be recalled the next time that input is selected, unless overridden by à Dolby Digital or DTS signal, which automatically invoke their native Listening Modes.

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 Additionally, if your system incorporates à subwoofer it establishes à correct relationship between the volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic elements

I is quite practical to perform the T 754 Level setup routines “by ear,* and careful work will produce acceptably accurate results. However, the use of an inexpensive sound-pressure level (SPL) meter, such as Radio Shack part number 33-2050, makes this task easier, more accurate and more repeatable. Ownership of such a meter could prove a valuable audio tool, your NAD audio specialist may be able to help you with temporary use of à meter. The SPL meter should be placed at the primary listening position, at approximately the height of the seated listener's head. À tripod is helpful, but with a little duct tape almost anything — a pole lamp, music-stand, or ladder-backed chair, for example — can do as well. Just be sure that no large acoustically reflective surfaces obstruct or are near the microphone element. Orient the meter with its microphone (usually at end) pointing straight up toward the celling (not forward toward the speakers) and ensure that its weighting scale is selected. Set the meter to display 75 dB SPL. (On Radio Shack meters this necessitates either setting the meter to its 80 dB range and taking your readings at the -5 point, or selecting the 70 dB range and reading at the +5 point.)

SETTING CHANNEL BALANCE

Press the HTR 2 remote‘s [Test] key, activating the T 754‘ channel-balancing test signal and displaying the <Channel Levels> menu on the OSD. You will hear à “surf” sound that cycles through your speakers, beginning with the left-front. (If you do not hear the test signal, check your speaker connections (above), and your <Speaker settings> OSD menu settings, (above.) 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 [ 4 / à 1 keys to adjust the loudness of the noise output from the currently playing channel to the required level (its 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 NOTE: li you are balancing levels “by ear°, choose one speaker—usually the center—as a reference and adjust each of the others in turn to “sound as loud" as the reference. Be sure that you remain in the primary listening position while balancing all channels Using the remote's [A /v ] and [ 4 / D ] keys adjust each speaker to produce the same SPL meter reading {or subjective loudness). Note that Al speakers must be in their final locations before level-setting Your subwoofer (if any) should be set with its integral crossover defeated, or if undefeatable, set to its highest-possible frequency if you are using the T 754's SUBWOOFER output. Final subwoofer-level adjustment “by-ear," using music and film sound material, is frequentiy useful Due to the effects of room acoustics, matched-pair speakers (front; surround; back) will not always calibrate to exactly the same level offset readings SPEAKER DISTANCE Your system's speaker distance settings are à subtle but important refinement of your setup. Informing the T 754 of the loudspeaker-to-lstener dimensions of each speaker automatically imposes the correct delays, optimizing imaging, intelligibility, and surround-sound ambience. Enter your dimensions with precision within about 1 foot (30 cm).

SETTING SPEAKER DISTANCE

From the OSD's main <Setup> menu, select the <Speaker Distance> item using the remote's [A / ] and [Enter] keys. Using the [ € / ] keys, set <Front> and <Center:> to the distance measuring from your principal listening position ta the front surface of the front and center loudspeakers. Using the same remote keys, set <Surround> to the distance of the nearest surround-channel speaker. NOTE: Distance can be displayed as feet or meters selectable by the <DISTANCE> item in the Speaker Distance menu. ADVANCED OPTIONS The T 754 allows for setting of special listening and system options. These are usually one-time options settings and once set do not need to be changed. Main/Zone DSP Decoding From the OSD' main <Setup> menu, select the DSP decoding options. There are two options, 5.1 and 7.1 decoding. With 7.1 decoding, the Zone output will be switched off. Dolby Digital Surround EX Decoding Select either Auto or On. If On is selected, the Surround EX decoding will be forced on thus Dolby Digital

5.1 will become 6.1 matrix.

DTS-ES Matrix Select either Auto or On. If On is selected, the ES Matrix will be forced on thus DTS 5.1 will become 6.1 matrix. BACKGROUND to “ON” or “OFF” When “ON” is selected, on-screen menus will appear against a black background, obscuring the current video program (if any), when “OFF” is selected menus will appear in white text superimposed upon the current video program if any) TEMP OSD TEMP O$D. When “ON” is selected, the temporary OSD such as volume, and speaker levels are displayed When “OFF” no temporary OSD wil be displayed

CREATING AND USING PRESETS

The T 754% simple but powerful 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 754 operation that is available from the main <Setup> menu — input settings, level settings, delay settings, speaker settings, and listening mode selection and adjustments — is stored, together, as a single Preset. You might create one Preset optimized for pop music and another for classical, or Presets that recall each family members favorite setup, or one for fully cinematic home-theater playback and another for late-night movies, with each Presets surround mode, channel levels, and speaker-setup fine-tuned to à particular scenario or preference. CREATING PRESETS Creating a Preset consists simply of storing a complete set of all settings accessible from the main <Setup> menu, including Tone Control settings. To save a collection of settings to a Preset, use the HTR 2 remote‘s LA + 1keys to scroll to the to main <Save to Preset> item. Use [A / v ] to scroll to the desired Presets line 1-5E <Stored> will be flashing. Now press the HTR 2 [Enter] to store the Preset; <Stored> will be stop flashing, confirming that the Preset has been stored NOTE: The selected Preset remains in force until you select a different Preset. NOTE: It is strongly recommended to leave Preset 1 “empty”; that is, memorized with no changes at all made to the calibrated values you have entered on all of the <Setup> menu lines. This will make returning to your calibrated setup defaults easy. RECALLING PRESETS You may recall a Preset at any time; the newly recalled Preset will replace the previous Preset (if any). Presets can only be recalled using the HTR 2 remote Press the HTR 25 square [AW Preset] key (red dot), then press the numeric key 1-5 corresponding to the desired preset. NOTE: The [AW Preset] key works as a momentary “shift” key: You must press it every time before invoking à Preset via à numeric key.

USI THE T 754 You may operate the T 754 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 25 remote's [Amp] device selected, the remote numeric-key section directly selects the receivers inputs, plus the internal tuner (Tuner), Tape Monitor (Tape)), and multichannel input ([Ext. 7.1/ 5.1) refer to the red labels directly above each key. + When an audio-only source (CD, DISC, TUNER) is selected, the most recently-selected video signal remains selected, until another audio-video input is selected + When you change sources, the VFL will display the new input in its primary display. + A newly selected input's listening mode (Stereo, EARS, Pro Logic 1, etc.) will revert to the mode to which it is configured on the <input Settings> line of the setup menu, unless the incoming signal is à Dolby Digital or DTS source, in which case the input will be set automatically to the appropriate decoding mode

ADJUSTING THE VOLUME

Use the HTR 2 remote’s <Volume up/down> keys to adjust the "master volume" of the T 754, raising or lower all channels together. Note that: +_ A momentary keypress will change the master volume by 1 dB increments; if you hold down <Volume up/ down> the master-volume change will *run-on" until the key is released +_ The T 754's OSD will show the volume setting as a line graphic with a numeric display above in dB relative to the reference level Since recordings vary considerably in overall average level, there is no imperative to listen at any particular master-volume setting. À setting of -20 may sound “as loud" from one CD or DVD as -10 does from another. +_ If muting has been activated (below), adjusting master-volume via the HTR 2 remote or the front-panel Knob automatically releases the mute function +_ The T 754 will power-up from Standby mode at whatever master volume setting was last used; however, ifthe prior setting was greater than -20 dB the T 754 will power up to -20 dB. This prevents inadvertently beginning à session at excessive volume.

Use the HTR 2 remote's <Mute> key to silence all channels completely. Muting is always available, regardiess of source or listening mode selections. Note that: + Cycling through Standby or powering off does release muting: the T 754 will return from Standby with muting off if Standby was invoked with muting on! + Changing input or listening-mode selections does not release muting. + Adjusting the master-volume upward via the HTR 2 or the front-panel knob automatically releases the mute function.

The T 754% internal AM/FM tuner offers very high quality sound from radio broadcasts. Note that reception and sound quality will always be dependent to a degree on the type of antenna(s) used, as well as proximity to the broadcast origin, geography, and weather conditions. ABOUT ANTENNAS 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 antenne will usually work best oriented vertically, with the arms of its ‘T” full outstretched and arranged perpendicular to the origin of the desired broadcast. There are no ‘rules,’ however, and experimenting freely with antenna placement and orientation may yield the clearest sound and lowest background noise. In areas of poor FM reception, an exterior FM antenna can improve performance dramaticall. If radio listening is important to you, consider consulting an antenna installation professional to optimize your system The supplied AM ‘loop’ antenna will usually provide adequate reception. However, an exterior AM antenna can be used to improve reception; consult an antenna professional for more information.

Press the AM/FM key on the T 754 front panel, the HTR 2% orange [TUNER] (the numeric 9 key), or the yellow [AMI and [FMI keys to select the receivers radio mode. Each subsequent press of either key will toggle the unit between its FM and AM bands. TUNING STATIONS Press SEARCH 4} on the front panel momentarily to step up or down between FM or AM frequencies. Press and hold SEARCH 4 P for more than 2 seconds to search up or down; the T 754% tuner wil stop at the next sufficientiy strong signal it encounters. See “Front Panel,” above. Pressing the SEARCH 4 D keys momentarly during the search process will stop the search After first pressing amber [TUNER] mode-select key on the HTR 2 to set the remote to control radio functions, press [TUNE DOVVNI or [TUNE UP] on the HTR 2 (yellow lettering); hold in to perform slow manual search, press momentarily to automatically search (see above)

SETTING RADIO PRESETS

The T 754 can store as many as 40 of your favorite radio stations for immediate recall, 30 FM stations and 10 AM. To store a radio preset, first tune the desired frequency (see above), then press the front panel MEMORY key. Press the PRESET 4 D key to select the preset number to be assigned. Then press the MEMORY key once again. The STORED message will appear in the VFL Display. NOTE: The Radio Presets must be stored from the front panel; this setup function is not accessible from the HTR 2 remote. NOTE: The T 7545 Radio Presets are distinct from its “global” Presets that can be used to manage listening and setup modes and levels. See “Using Presets,” above.

SELECTING RADIO PRESETS

Press PRESET 4 D on the front panel to step up or down between presets; press and hold PRESET 4 to “scroll” continuously up or down. The HTR 2 remote's [PRESET 2 / + ] keys work similarly

CHOOSING THE FM MUTE / MODE

The front-panel FM MUTE/Mode key is a dual-purpose control. First, it “toggles” the T 754 between stereo mute and unmated stereo reception (assuming that à multiplex-stereo station of sufficient strength is tuned). FM Mute eliminates noise from “empty” FM frequencies but also mutes very weak or distant stations; it also causes the search function to skip them. Toggling off the FM Mute will result in reduced noise if the FM station signal level is less than the FM Stereo threshold (since mono FM is inherently less noise-prone), though at the sacrifice of the stereo effect. NOTE: The one can store the same channel in two preset locations; one with FM Mute On, and with FM Mute Off. NOTE: Toggling between FM Mute on or off also defeats the T 754% FM muting circuit. f you wish to listen to à particularly weak or distant broadcast, toggle off the FM Mute and tune it manually. ABOUT RDS The Radio Data System (RDS) permits compatible FM receivers to display text determined by the broadcaster. The T 754 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). However, not every FM station incorporates RDS in its broadcast signal; in most areas you will find from one to several RDS- enabled stations, but it is by no means impossible that your favorite stations will not be broadcasting RDS data

When an RDS-enabled FM broadcast is tuned, after a brief delay the “RDS” symbol will light in the T 7545 front-panel readout and the readouts character section will show its station-name (PS) text: “ROCK 101," for example. Press the front-panel DISPLAY key to toggle the readout between this and the station‘s radio- text (RD) readout, if any, which might scroll song- or artist-name, or any other text of the station's choosing

You can assign an eight character “User Name” to each radio preset, which will show in the front-panel readout whenever that preset is recalled

For example, to name a radio preset “NEWS”: recall the desired radio preset, and then press the front-panel MEMORY key once, then within five (5) seconds, press the front-panel DISPLAY key; the readout shows à blinking box. Use the SEARCH 4 keys to select the first character of the name (“N” from the alphabetic list; press either PRESET 4} key to select the character and move to the next position. Repeat this process for each character in sequence; press the MEMORY key again to store the User Name and exit the text-entry mode

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 I also offers a broader dynamic, producing magnificent sound quality. DTS - ES EXPANDED SURROUND TM (DTS ES) This is a new multichannel digital format which greatly improves the 360° spatial sensation of the Surround impression thanks to the greater space expansion of the surround signals, providing high compatibility with the conventional DTS format. In addition to the 5.1 channels, the expanded DTS-ES Surround also offers the back surround (also sometimes called the “surround centre") in reproduction, providing a total of 6.1 channels. The expanded DTS-ES Surround includes two formats, with two different methods of surround signal recording, as follows DTS-ESTM DISCRETE 6.1 Since the signals of the 6.1 Surround channels (including the back channel) are completely independent, it is possible to achieve the sensation that the acoustic image is moving about freely among the background sounds, 360 degrees surrounding the listener. Although maximum quality is achieved with sound tracks recorded using this system and reproduced using the DTS-ES decoder, when played with a conventional DTS decoder, the back surround channel is automati- call downmixed in the surround right and surround left channels of the surround system, in such a way that none of the signal components are lost.

DTS - ESTM MATRIX 6.1

In this format, the additional signals of the back channel receive à matrix encoding and are inputted into the right and left surround channels. During reproduction they are decoded to the right, left and back surround channels Since this bit-stream format is 100% compatible with conventional DTS signals, the DTS-ES Matrix 6.1 format effect can also be achieved from sources with DTS-ES 5.1 signals. Natural, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in DTS-ES 6.1 When à DTS-ES decoder processes decodes a discrete DTS-ES 6.1 or in Matrix 6.1, these formats are automatically detected and the Optimum Surround mode is selected However, some DTS-ES Matrix 6.1 sources may be detected as DTS. In this case the DTS-ES Matrix mode should be selected manually in order to reproduce them

DTS NEO: 67 SURROUND

This mode applies the conventional 2-channel signals such as digital PCM or analog stereo signals to the high precision digital matrix decoder used for DTS-ES Matrix 6.1, to achieve 6.1-channel surround playback DTS Neo: 6 surround includes two modes for selecting the optimum decoding of the signal sources

This method is ideal for the reproduction of movies. The decoding takes place by emphasising the separation in order to achieve the same atmosphere with 2-channel, as with 6.1-channel sources.

Meinly recommended for music reproduction. The right and left front channels do not pass through the decoder and are reproduced directly so there is no loss in sound quality, and the effects of the right surround, left surround, central and back surround channels add a natural sensation of expansion of the sound field “DTS", “DTS-ES Extended Surround” and "Neo: 6" are registered trademarks of Digital Theater Systems, Inc. DOLBY DIGITAL Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs bearing the “DOLBV/Digital” symbol were recorded with up to 5.1 channels of digital signals, reproducing a much better sound quality, with dynamic and spatial sound sensations that are much better than in the previous Dolby Surround.

Using a Matrix decoder this method creates the back channel (sometimes also called the “surround center”) by means of signals on the left and right surround channels recorded in Dolby Digital 5.1, reproduction being provided in Surround 6.1. This method should be selected with sources bearing the “DOLBY/Digital -EX" symbol, recorded in Dolby Digital Surround EX. With this additional channel you will experience improved dynamics and a better sensation of movement within the sound field If media sources recorded in Dolby Digital EX are decoded with a Digital EX decoder, the format is detected automatically, and the Dolby Digital EX mode is selected However, some media sources recorded in Dolby Digital EX can be detected as simple Dolby Digital media sources. In this case Dolby Digital EX should be selected manually.

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 à 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. to surround processing which offers improvements over conventional Dolby Pro Logic circuits. Dolby Pro Logic Il surround has two decoding modes

DOLBY PRO LOGIC II MOVIE

Designed for the cinema, this method highlights the cinematic sound quality by adding à process that emphasises the special effects of action scenes

DOLBY PRO LOGIC II MUSIC

Designed for music, this method highlights the sound quality of music by adding a process that emphasises the musical effects Manufactured under license from Dolby Laboratories. “Dolby”, “Pro Logic”, and the double D symbol are registered trademarks of Dolby Laboratories.

ABOUT THE T 754'S LISTENING MODES

The T 754 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 Alloutput is directed to the leftright-front channels; low frequencies are directed to the subwoofer if one is present in the Speaker settings. Select Stereo when you wish to listen to a stereo (or monaural) production, such as a music CD or FM broadcast, without surround enhancement. Stereo recordings, whether in PCM/digital or analog form and whether surround-encoded or not encoded, are reproduced s recorded multichannel digital recordings (Dolby Digital and DTS) are reproduced in “Downmix" mode via the left- and right-front channels only, as LUR (left/ight-total) signals. Dolby Pro Logic Dolby Pro Logic Il (PLII) Two-channel recordings, whether stereo or surround-encoded, are reproduced with Dolby Pro Logic, or ProLogic Il surround processing, yielding output to left., center., and right-front channels, and discrete leftright surround channels (assuming these are present in the current <Speakers Setup>. PLII does not employ the surround back speakers (if any) NOTE: ProLogic I is à more recent evolution of the original Dolby ProLogic surround processing that yields more stable imaging and full bandwidth sound to the rear channels in Movie mode, offering sound that is more similar to Dolby Digital decoding. The T 754 provides two PI variations: MOVIE and MUSIC. See “Adjusting Listening Modes,” below DTS Neo:6 Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround with output to left, center., and right-front channels and discrete left/right surround channels (assuming these are present in the current <Speakers Setup>) The T 754 provides two DTS Neo:6 variations: CINEMA and MUSIC. See “Adjusting Listening Modes," below + EARS TWwo-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD surround processing with signals output to the left, center, and right-front channels and discrete left/ right surround channels, plus subwoofer (assuming these are present in the current <Speakers Setup>); EARS does not employ the surround back speakers (if any). EARS extracts the natural ambience present in nearly all well-produced stereo recordings. It does not synthesize any ambience or other sonic elements and thus remains truer to the sound of the original musical performance than most other music-surround options Select EARS for listening to stereo music recordings and broadcasts. EARS produces a subtle but highly natural and believable ambience from nearly all “natural-acoustic” stereo recordings; typically, these include classical, jazz, and folk genres as well as numerous examples from others. It's virtues include à realistic, stable “front-stage* sonic imaging and spacious but unexaggerated ambient “virtual acoustics* that remain faithful to the original recording. Matrix 7.1 Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary surround processing via the full suite of front, surround, and one or two surround back speakers (if these are present in the current Speaker Settings setup), plus subwoofer (if any). Matrix 7.1 can produce à very natural, cohesive all-channels surround from high-quality recordings, both for stereo music and for surround-encoded music or movie programs. Enhanced-Stereo 1 (ST1) All recordings reproduced in stereo via the maximum speaker complement configured in the current <Speakers Setup>. STI can be useful for maximum volume from all channels, or for multi-speaker background music (cocktail party) listening

+ 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 <Speakers Setup>. ST2 can prove useful in certain late-night or very low-volume listening situations. The following Surround Sound Modes require à specially encoded signal that must be present in digital format to be decoded by the T 754. These modes are automatically switched on when the appropriate data stream is detected selected in the setup menu of the source media. + Dolby Digital + Dolby Digital EX + Dolby Digital Surround Sound EX + DTS + DTS ES Matrix + DTSES 6.1 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 <Speaker Settings> setup). NOTE: The DVD player must be sending a Dolby Digital or DTS bit-stream from its digital output. Your DVD player probably includes its own setup menu that (among other things) lets you select the default bit- stream format, and usually includes an “Auto” setting that directs the player to choose the Dolby Digital” DTS signal whenever these are available. In à few cases, you may have to set the players bit-stream manually to “DD/DTS" or an equivalent. In the case of DVDS that carry both Dolby Digital and DTS, you will select one or the other from the disc (not the player) main menu Note also that while most Dolby Digital recordings are 5.1-channel surround productions, older examples may be multichannel, 2-channel, or even monaural, the T 754 will automatically reproduce the Dolby Digital signal with the maximum number of channels available. Both Dolby Digital’EX and DTS/ES 6.1-channel recordings are reproduced using the surround back channel, if present in the current Speaker Settings setup; additionally, the T 754 creates surround-back signal from non-EX/ES, 5.1-channel Dolby Digital and DTS recordings. Dolby Digital EX creates six full-bandwidth output channels from any 5.1-channel Dolby Digital recordings. The very best results occur with movies or other programs bearing the Dolby Digital Surround EX mark, which are produced to take full advantage of this playback mode The table below indicates which listening modes are available with the to types of audio signal sources: digital- or analog-input 2-channel (whether the actual signal is monaural, stereo or surround-encoded), and digital-multichannel (Dolby Digital or DTS). Where a listening mode is not available to a given signal source, it will not appear in the <Listening Mode selection rotation 2-ch analog or PCM Multi-ch.

Keying the front panels DISPLAY or HTR 2 remote's [DISP] key will display on the VFL the channel-mode of the currently selected input signal, in the format “front/surround.subwoofer” (see 5 DISPLAY” in the “Front Panel” section) The following table shows examples of displays seen with various signal types: Source Readout/OSD Analog Analog Digital PCM/HDCD Digital PCM/HDCD Multichannel (Dolby Digital) Dolby D 3/2/.1 (full surround) Dolby D 3/1/.1 Dolby D 2/0 etc. Multichannel (DTS) ds 3/2/.1 (full surround) dts 3/1/.1 dts 2/0 etc.

SELECTING LISTENING MODES

Keying the HTR 2 remate's [SURR MODE] button steps through each of the T 7545 Listening Modes available to the current input signal. It also momentarily displays the Listening Mode in the OSD. NOTE: Changing the type of input signal may automatically change the Listening Mode: f the new signal is a Dolby Digital or DTS recording, it will automatically invoke its native mode. The reverse is also true if Dolby Digital or DTS was previously selected 23

Several of the T 754% listening modes have one or mare 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 754% VFL Display. One can also select variations using the HTR 2 [ € / } ] cursor keys on the <MODE:> line of the OSD. Use the HTR25[4/v] and [ 4 / à ] cursor keys to navigate among and modify that mode's adjustable parameters (if any NOTE: Listening Mode parameter changes are maintained when you change listening modes. You may also save à modified Listening Mode for easy recall by saving it to a Preset (see “Using Presets”, above.) Dolby Pro Logic II (PLII) PLI MOVE is optimized for film soundtracks. PLII MUSIC for music recordings. DIMENSION (-3 to +3): Adjusts front-rear emphasis of the surround effect independentiy from the relative channel levels CENTER WIDTH (0 to 7): Modifies the “hard-centeredness” of the center image, by gradually mixing mono-center content to the front-lefright speakers as well; a setting of O retains the center-channel- only default, while a setting of 7 yields à fully phantom center channel. PANORAMA (ON/OFF): Adds a “wraparound" effect by extending some stereo content into the surround channels DTS Neo :6 Neo: 6 CINEMA is optimized for film soundtracks, Neo:6 MUSIC for music recordings. Stereo HDCD (stereo PCM) Downmix Dolby Digital Dolby Digital EX Enhanced-Stereo 1 (ST1) Enhanced-Stereo 2 (ST2) DYN. RANGE (25, 50, 75, 100PCT): You can select the effective dynamic range (subjective range from soft to loud) for playback of Dolby Digital soundtracks. For fully cinematic effect, always select 100PCT, the default. Settings of 75, 50, and 25PCT progressively reduce dynamic range, making soft sounds compara- tively louder while limiting the peak loudness of loud ones; the 25PCT setting will yield the least dynamic range and is best for late-night sessions or other times when you wish to retain maximum dialog intelligibility while minimizing overall volume levels

ADJUSTING CHANNEL LEVELS “ON THE FLY"

You can make changes to the relative levels of center, surround, and subwoofer outputs. This may prove useful in à number of circumstances; for example, to increase (or tone down) a film's dialog level by raising lowering) the center channel, or to reduce excessive deep bass (or enhance deep bass) by lowering {raising) the subwoofer level without having to go into the CHANNEL LEVELS OSD menu.

TO ADJUST CHANNEL LEVELS

Use the HTR 2 remote's [Surr:], [Center], and [Sub] [A / + ] keys for direct-access level adjustment of these channels, over a range of +12 dB. You can also adjust all channel levels using the front panels Levels key (see “Front Panel,” above), or via the <Channel Levels> line of the main <Setup> menu NOTE THAT: The surround back channels (if any) adjust in lockstep with the surround channels; Channel Level changes made via the HTR 2 are retained even if you cycle the receiver through Standby. Channel Levels are part of the T 754% Preset system. See “Creating and Using Presets,” below. Level settings are added/subtracted to the setup levels established by the T 754 level-calibration routine, invoked by the HTR 2 [Test] key, However, selecting any Preset will revert channel levels to those stored in the preset.

ADJUSTING THE TONE CONTROLS

The T 754 bass and treble controls are adjusted using the front panel's TONE CONTROLS (and TONE DEFEAT) buttons; see “Front Panel," above. NOTE: Bass/reble settings affect only the front lefright channels, and are active in all listening modes. BassAreble settings are part of à Preset: Bass/treble settings in effect when a Preset is stored will be reinstated whenever that Preset is recalled

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 754 receiver right out of the box, but it is really eight remotes in one. Each of the 8 Device Selector keys at the top of the handset can call up a new “page” of remote- control codes to be transmitted by the remaining 44 keys. You may “teach" codes from any infrared-remote- contrelled component, regardiess of brand, to any or all of these. Obviously, the most logical system is that you teach the codes from your DVD player to the [DVD] Device Selector “page,” your television's codes to the [TV] “page,” and so on, but there is no required scheme: You may load any commandé to any key on any page (see “Learning Codes From Other Remotes,” below) The HTR 2 is already preprogrammed with à full complement of commands for the T 754 receiver on its [AMP] Device Selector page, and as well as with library commands to operate most NAD-brand DVD, CD, or TAPE components on the corresponding Device Selector pages." These default commandés are permanent: Even if you teach the HTR 2 new commandé to take their place, the underying library commands remain in place and can easily be recalled should you add an NAD component to your system later (see “Delete Mode”, below NOTE: For use with the T 754, it should not be necessary to re-program any keys on the HTR 2 [AMP] page. However, in order for the HTR 2 to control our specific NAD-brand components you may need to load one or more different code-libraries; see “Loading Code Libraries,” below.

CONTROLLING THE T 754

The HTR 2 is divided into two main sections. Eight Device Selector keys at the top—[AMPI, [DVD,] [TV] and so on—set the handsetS remaining keys to à “page” of commandés to control a particular component. A Device Select key determines only what component the HTR 2 will command; it does not perform any function on the receiver. AI of the remaining keys are function keys that can “learn” control codes from virtually any infrared remote controller, allowing you to teach the codes of your equipment, regardless of brand, to the HTR 2. However, the HTR 2 is already preprogrammed to operate the T 754. All of the function keys on the [AMP] Device Selector “page” perform T 754 functions. (The HTR 2 can also command many other NAD compo- nents, from its [DVD] [CD,] [TUNER] and [TAPE] pages.) Itis important to note that certain HTR 2 keys perform different functions depending on the selected Device Selector “page.” The color of the Device Selector key-labeling corresponds to the labeling of the function Keys. Most central}, the red [AMP] Device Selector “page” corresponds to the red input-select labeling adjacent to the numeric keys: When the HTR 25 [AMP] Device Selector page is active, these keys select the receiver inputs. Similar, the purple [DVD] Device Selector “page” corresponds to several purple labels, the green [TV] page to green labels, and so on

LEARNING CODES FROM OTHER REMOTES

Begin by positioning the HTR 2 “nose-to-nose” with the source remote so the two devices’ infrared windows are about 2 inches apart Enter Learning Mode: On the HTR 2, simultaneously press-and-hold for 3 seconds both a Device Selector Key and the [e] “record” key (ust below the [DISP] key), until the Learn LED at the center of the HTR 2 turns steady green Press the HTR 2% function key you wish to teach a command the Learn LED will turn amber. Press-and-hold the function key on the source remote: The HTR 25 Learn LED will flicker amber for a second or two, then turn solid green. The command is learned Press the HTR 25 Device Selector key again to exit the learning mode If the Learn LED does not flicker amber you may need to vary the distance between the remotes. If the Learn LED turns red rather than green, that particular command of that source remote command could not be learned Cancel Operation: You can cancel configuring a key, by pressing the active Device Selector key before the learn is complete; the Learn LED will turn red. Example: Learning “DVD Pause": Position the HTR 2 and your DVD player remote as described above. + On the HTR 2, simultaneously press-and-hold [DVD] and [+]; the Learn LED turns steady green Press the HTR 25 [ |] ] (pause) key; the Learn LED turns amber. Press-and-hold the DVD players remote pause key; the HTR 2 Learn LED flickers amber and then turns solid green. The command is learned Press [DVD] again to exit the learning mode.

PUNCH-THROUGH The HTR 25 “punch-through” function allows you to retain à function key from one Device Select “page” on another, so that, for example, the AMP [SURR MODE] function might still control the T 754 when the DVD Device Selector page is active NOTE: The HTR 2' [VOL] keys are pre-programmed as “punched-through” for all Device Select pages. VOL will operate the T 7545 mastervolume regardiess of the currently selected device. The [SURR.] ICENTER,] and [SUB] Channel Volume controls similarly are pre-programmed as punched-through To set a punch through, after entering the Learning Mode, and pressing the desired key to be punched- through, simply press the device key twice of the device to punch through to. The status LED will turn green; press the Device Selector key again to exit Learning Mode. Example: Punch-through the from the DVD “page” to the AMP [SURR MODE] key: + On the HTR 2, simultaneously press-and-hold [DVD] and [+] (record); the Learn LED turns steady green + Press [SURR MODE], the Learn LED turns amber. + Press [AMP] twice; the Learn LED turns green + Press [DVD] again to exit the learning mode

COPY A COMMAND FROM ANOTHER KEY

You may copy à command from any HTR 2 key to any other. To copy a key function, after entering the Learning Mode, and pressing the desired key to be copied to, simply press the device key from which you wish to copy, having first pressed its Device Selector key if it resides on another “page.” The status LED will turn green; press the Device Selector key again to exit Learning Mode. Example: Copy the Pause command from the CD page to the AMP [ ||] key: + On the HTR 2, simultaneously press-and-hold [AMP] and [e] (record); the Learn LED turns steady green. + Press [ 11] (pause); the Learn LED turns amber. + Press [CD]; press [ 11] (pause); the Learn LED turns green. + Press [AMP] again to exit the learning mode NOTE: The copy and punch-through functions are similar. However, if you copy à command and then subsequentiy delete, or over-write the original (source-key) command , the copied-to keys command remains unchanged. If you punch-through to a command and then delete or over:write the original key, the punched-through functions also change accordingly. MACRO COMMANDS À “macro” command is a series of two or more remote codes issued automatically from a single keypress You might use à macro to automate a simple command sequence, such as, “Turn on the DVD player and then press ‘play. Or you might compose an elaborate macro to power up an entire system, select a source, choose a Listening Mode, and begin playback—again, all from a single keypress. The HTR 2 can store one macro on each of its function keys (these exclude the Device Selector keys). NOTE: Macros are independent of the currently selected device RECORDING MACROS To record à macro, simultaneously press-and-hold for 3 seconds both the [MACRO] key and the HTR 2 function key to which you wish to assign the macro, until the status LED turns green. The macro button will also light up. Press the sequence of function keys to be recorded into the macro, being sure to first press the requisite Device Selector key for each function (you may switch devices while recording the macro as many times as necessary) allowing you to create macro containing commandé from more than one Device Selector “page.” When you have finished entering the desired command sequence, press [MACRO] again to store the macro; the Learn LED and [MACRO] key illumination will turn off. NOTE: Each macro can store a maximum of 64 command steps. If you exceed this number, the macro will be stored automatically after the G4th command is added Example: Record a Macro to the [0] key to Turn on the T 754, Select the DVD Input, and Commence Playback: + On the HTR 2, simultaneously press-and-hold [MACRO] and [0] (numeric zero); the Learn LED turns steady green Press [AMP]; press [ONI; press [1] (red “DVD*); press [DVD]; press [play] (the Learn LED blinks as each step is added) Press [MACRO] again to exit the macro-record mode To clear a macro, perform the above steps without entering any functions EXECUTING MACROS To execute à macro, press and release [MACRO/; its key illumination lights for 5 seconds. While it remains lit, press an HTR 2 key to which a macro has previously been stored. The corresponding macro will run; as each step executes, its “parent” Device Selectors key flashes lights briefly; when execution is finished, the IMACROI key illumination goes out. Pressing any other HTR 2 key while à macro is executing will abort the macro. Remember that you must hold the HTR 2 so that its infrared emitter can activate the target components 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. 27

KEY-ILLUMINATION TIMEOUT The HTR 25 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' [DISP] and the 10-9] 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 NOTE: Keyillumination is the biggest drain on the HTR-25 batteries. A short key-illumination timeout will extend battery life appreciably; turning it off altogether (set it to 0 seconds) will lengthen it still further. FACTORY RESET The HTR-2 can be reset to its factory state, deleting all learned commands, copied and punched-through Keys, macros, and other setup information, reverting all keys to their pre-programmed library commands. To perform a factory reset simultaneously press-and-hold for 10 seconds the HTR 2'5 [ON] and [RTN] keys; the Learn LED will start to flash green. Release [ON] and [RTN] before the second flash is complete; the Learn LED will turn red, indicate the remote has been reset NOTE: You must release [ON] and [RTN] before the second flash goes out, otherwise the unit will not reset; should this occur, repeat the full procedure. DELETE MODE The HTR 2 can store learned, copied, and “default library” commands on any single key. (The default library commandé are the pre-programmed NAD codes, such as the native T 754 commands on the [AMP] “page. “) You can delete commands by layers back “down” to the default library command on any key, removing learned commands, punched-through functions, and copied keys NOTE: The default library commands cannot be deleted, so you need not worry that using Delete Mode might cause irreparable changes To enter Delete Mode, simultaneously press-and-hold for 3 seconds both the desired keys Device Selector Key and the [RTN] key, until the Learn LED turns green. Press the function key whose command you wish to delete; the Learn LED flashes; the number of times indicates which type of function has become active— see the table below. Press the active Device Selector key again to exit Delete Mode. NOTE: You may delete multiple function-key commands on the same Device Selector “page,” but to delete from mare than one Device Selector page you must exit Delete Mode and then re-enter it on the required page Flashes Command Type 1 Default Library Command 2 Copied Library Command Learmed Command LOADING CODE-LIBRARIES The HTR 2 can store a different library of default NAD codes for each of its Device Selector “pages.” If the original default library does not control your NAD CD player, tape deck, DVD player, ar other component, follow the procedure below to change the code-library. Begin by ensuring that the component you wish the HTR 2 to control is plugged in and powered-up (“on,” not merely in standby). To enter the HTR 25 Library Mode, simultaneously press-and-hold for 3 seconds both the desired Device Selector key and the [AW PRESET] key, until the Learn LED turns green. While keeping the HTR 2 pointed toward the component, enter the first appropriate three-digit code-library number from the table below. If the component turns off, press [ENTER] to accept that code-library number and exit the Library Mode. If the component does not turn off, enter the next three-digit code-library number from the table. When you enter the correct number the component will turn off; press [ENTER] to accept that code- library number and exit the Library Mode NAD-brand component HTR 2 code-library numbers

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 simultaneousiy pressing-and-holding for 3 seconds both the desired Device Selector key and the [AW PRESET] key, until the Learn LED turns green. Now press-and-hold the HTR 2 [A ] (or LD key, the remote will step through al the available codes at a rate of approximately 1 per second. When the component turns off, immediately release the cursor key; press [ENTER] to accept that code-library and exit the Library Mode. Try a few commandés; should you prove to have stepped past the needed code-library, re-enter the Library Mode and use the cursor key to step back to it. NOTE: it is possible that search mode will find code-libraries that operate, at least partially, some other- brand (non-NAD) components. You may certainly exploit such capabilities as you find them. However, since we can only ensure the completeness or accuracy of NAD code-libraries, we cannot support the HTR 2 operation with other-brand components. Checking Code-Library Number You can check the current code-library on any Device Selector key as follows. Enter Library Mode by simultaneously pressing-and-holding for 3 seconds both the desired components Device Selector key and the [AW PRESET] key, until the Learn LED turns green. Press the [DISP] key; the HTR 2 indicates the current code-library by flashing its TAPEI, [VCRI, and [MACRO] keys. For example, to indicate code-library #501 the HTR 2 will flash [TAPE] 5 times, pause, and then flash [MACRO] once. You might wish to make a note of your components’ code-library numbers.

The ZR 2 remote control is a discrete compact remote for controlling the T 754 from various rooms other than the main room. The ZR 2 remote allows full separate control of the source selection irrespective to the main room. This means the zone input may be completely different, audio and video, from the main input and thus corresponding volume levels as well. If one wishes to enjoy the same source, as the main room the ZR 2 remote has a [LOCAL] button to allow simultaneous listening, but with full separate volume levels The T 7545 front florescent display will show activity of the zone control so that main room occupants are aware of the zone remote activity. Furthermore if there is no main room activity, only the zone indicator will be active in the T 7545 fluorescent display TRIGGER SETUP The T 7545 rear-panel TRIGGER output can be assigned to any of its six AV inputs: DVD, SAT, VCR, VIDEO 4-6. Whenever the assigned input is selected, either manually or by recalling a Preset, the TRIGGER output will produce +12 V DC, which can be used to activate à connected component or system. See your NAD audio specialist for more information.

ASSIGNING THE TRIGGER OUTPUT
