GETTING THE MOST FROM THE NAD T 773
Thank you for choosing NAD. The T 773 A/V 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 773 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 A/V Receiver is as musically transparent and spatially accurate as possible, incorporating much of what weve learned from a quartercenturys experience designing audio and home-theater components. As with all our products, NADs Music First design philosophy guided the T 773s 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 773, and get the most from this powerful and flexible hometheater component. One more thing: We urge you to register your T 773 ownership on the NAD Worldwide Web site: < http://NADelectronics.com/w/Registration.html > For warranty information contact your local distributor.

UNPACKING AND SETUP

WHATS WHATS IN THE BOX
Packed with your T 773 A/V 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 773 arrived. Should you move or otherwise need to transport your A/V Receiver, this is by far the safest container in which to do so. Weve seen too many otherwise perfect components damaged in transit for lack of a proper shipping carton, so please: Save that box!
LOCATION CHOOSING A LOCATION
Choose a location that is well ventilated (with at least several inches to both sides and behind), and that will provide a clear line of sight, within 25 feet/8 meters, between the A/V Receivers front panel and your primary listening/viewing positionthis will ensure reliable infrared remote control communications. The T 773 generates a modest amount of heat, but nothing that should trouble adjacent components. It is perfectly possible to stack the T 773 atop other components, but the reverse usually should be avoided. Nonetheless, it is generally preferable that the T 773 stand alone. It is especially important that sufficient ventilation be provided; if you are contemplating locating the T 773 within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.

3 Extend the antenna cord.

ABOUT THE T 773

Though the T 773 is among the most technically sophisticated A/V Receiver, we worked hard to make it one of the most musically transparent home-theater components available as well; this is what we mean by NADs Music First design philosophy. Here are just a few examples: The T 773 uses NADs proprietary Power Drive amplifier technology for all channels to preserve accurate, linear reproduction regardless of the loudspeaker. This uniquely efficient power-supply topology provides the real-world benefits of high dynamic power that remains uncompromised by lowimpedance speakers. The result is dynamic, detailed, un-receiver-like sound in stereo and multichannel modes alike. NADs exclusive Soft Clipping circuitry further enhances sound quality and dynamic potential. High-performance components used throughout the A/V Receivers analog audio circuits maximize quality from all sources, including multi-channel analog sources such as DVD-Audio and SACD. Preamp output (all channels) and main-amp input jacks make potential expansion as flexible as possible. A Second set of Speaker terminals (Speakers B) for remote listening. Second Zone (MULTISOURCE) pre-amp and video feed with assignable 12 V DC trigger control. An RS-232 port for advanced zone control and software update through a Windows compatible PC. Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.
MATRIX DIGITAL E.A.R.S., MATRIX AND DIGITAL SURROUND
A key element of the T 773s unique musical aptitude is NADs proprietary Enhanced Ambience Recovery System (EARS). In sharp contrast to many ambience-synthesis music-surround modes, EARS exploits the T 773s substantial DSP power to route the ambient content that is encrypted in virtually all naturalacoustic 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 773 also incorporates a second proprietary surround mode, Matrix 7.1. This creates a full 6.1/7.1-channel environment from stereo and surround-encoded recordings, oftentimes with extraordinarily good results. Dolby ProLogic II Music and DTS Neo:6 Music modes can also create enjoyable experience from 2-channel sources. On the digital side, the T 773 combines extraordinarily high-speed DSP processing employing one of the most advanced high-speed DSP engines available, with fully 24-bit, 192 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.

EASE OF USE

Despite the effort NAD has invested in the T 773 A/V 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 773s 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 a single keypress.

INTEGRATION INTEGRATION

The T 773 A/V 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.
(MULTISOURCE) SECOND ZONE (MULTISOURCE)
The T 773 A/V Receiver is equipped with a full second Zone control through the ZR 2 remote and the use of Video and pre-amp level audio outputs. Complete access to volume, On/Off, all inputs including the local input is available.

RS-232

Flexible system configuration is possible with the RS-232 interface and NADs proprietary Windows compatible software. This interface allows complete remote control of the T 773 from any remote location via the PC. Complete remote control functionality is available to the user by interface software. See your NAD audio specialist for further information.

UPGRADABILITY

The T 773 A/V Receiver permits flexible system growth via individually accessible pre-out and main-in jacks for all channels. We have made the more likely scenario of software upgrades easy to accomplish via the high speed RS-232 port on the rear panel of the T 773. Owners who register their T 773 on our international web site www.NADelectronics.com will be advised of updates. Some of these may be free of charge, and some may require royalty payments depending on the type of upgrade. The advanced user will be able to perform these upgrades by downloading files from our web site via e-mail, and installing them by connecting the T 773 to a PC. Alternatively the dealer from whom you purchased your T 773 should be able to assist in performing these upgrades.

ABOUT THE HTR 2 SYSTEM REMOTE CONTROL
Packed with your T 773 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 remotes layout and operations before proceeding to setup your A/V Receiver. 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 a 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 773 A/V Receiver, we provide the following Quickstart instructions to get you underway. The steps below connect your DVD player to the T 773s DVD input; be sure to read Input Setup, below.

PLAY PLAY A DVD MOVIE

Connect the T 773s composite video or S-Video MONITOR OUT jack to your TV/monitors corresponding input (Cables not supplied). Connect your DVD players composite video or S-Video output to the T 773s corresponding DVD input. Connect the DVD players optical digital output to the T 773s optical DIGITAL IN 1 input (Optical cable not supplied). Connect your left and right front speakers to the T 773s FRONT L and R outputs, being sure to connect red to red (+) and black to black (-), with care to avoid stray wires or strands crossing between terminals. (Connect center, surround, and surround-back speakers as well, if you like). If your system includes a powered subwoofer, connect the T 773s AUDIO PRE-OUT SW1, 2 or both jacks to its line inputs. Press in the main power switch (black pushbutton) on the T 773s rear panel (this puts the T 773 into STANDBY mode and illuminates an amber LED to indicate it is ready to receive remote commands), then use the HTR 2s [ON] key to power up the A/V Receiver. Be sure the TV/monitor is powered up, with the correct input selected. Start playback of the DVD player. Press the HTR 2 remotes [Amp] Device Selector key, and then its (red) DVD/numeric 1 key to select the DVD input. You should hear multi-channel or stereo sound, and see an image on the TV/monitor. (If one or the other fails to appear, you may need to use the A/V Receivers onscreen menu system to check assignment of audio, video, and digital inputs; see Setting Up the T 773.) 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 773 carefully and completely.

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 a professional antenna installer. The AM loop antenna supplied with the T 773 (or a suitable replacement) is required for AM reception. Open the clip terminal lever, insert the wire and close, ensuring that the lever locks the wire in place. Testing different positions for the antenna may improve reception; vertical orientation will usually produce the best results. Antenna proximity to large metal objects (appliances; radiators) may impair reception, as will attempts to lengthen the wire to the loop. NOTE: An external AM antenna can improve long-distance reception substantially; consult your NAD audio specialist or a professional antenna installer. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna.

NOTE: The T 773s component-video inputs and outputs are fully wide-band, compatible with all HDTV formats. The T 773 does not display its on-screen menus on its component-video output. To use on-screen menus, you will need to make an S-Video or composite connection between the T 773 and the monitor/TV, and select it for menu display. 9 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 a CD recorder, DAT deck, or computer soundcard. See "Setting Up the T 773", below. 10 RS-232: Connect this interface via RS-232 serial cable (not supplied) to any Windows compatible PC to allow remote control of the T 773 through NADs proprietary PC software. See your NAD audio specialist for more information. 11 POWER: Press in to switch the A/V Receiver to standby mode. Pressing POWER again turns the unit OFF, recommended if you do not plan to use your A/V Receiver for an extended period of time. It is usual (and perfectly acceptable) to leave the T 773 in Standby mode in between normal viewing and listening sessions. 12 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. 13 AC POWER INLET: Connect to the supplied IEC-standard removable AC power cord or a compatible cord. 14 SPEAKERS A & B: Connect the left and right front, centre, left and right surround, and surround back speaker outputs to the corresponding loudspeakers. Each outputs + (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 773 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-circuits, 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 A/V Receivers operating range. Please check front, center, and surround speakers are rated to be 4 min. per speaker. IMPORTANT NOTE: For optimum surround performance, the T 773 speaker settings and levels must be set correctly via the A/V Receivers setup routines; see Setting Up the T 773, below. 15 DVD, SAT, VCR, VIDEO 4, VIDEO 5: These comprise the T 773s 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 773 S-Video/composite video OUT jacks to these components record-inputs. (Note that VCR/VIDEO 4 may freely be used for play-only components, in which case their OUT jacks would remain unconnected.) 16 MAIN IN/AUDIO PRE-OUTS/SUBWOOFER OUT: The T 773s 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 773 as a 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 builtinto the T 773 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 773 is so configured (see Speaker Setup, below). Either one or both channels are available mono or stereo as per Speaker Setup. Your NAD audio specialist will be happy to advise you. NOTE: Never connect the T 773s speaker outputs and the speaker outputs of an external amplifier to the same speakers. 17 TAPE IN/OUT: Connect the T 773s 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 a stereo equalizer; connect the A/V Receivers TAPE IN jacks to the components corresponding outputs. The signals present at the TAPE IN jacks can be heard by selecting the front panel TAPE MONITOR button, or the HTR 2s [Tape] (zero) key. NOTE: The signal present at the TAPE OUT jacks is determined by the source last selected via the front panel Video or Audio keys (or the HTR 2s input-select keys). NOTE: Digital input signals are not available at the analog TAPE OUT jacks; they are only available at the DIGITAL OUT jacks. 18 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 773 requires an outboard magnetic phono-preamp component such as the NAD PP2; you cannot connect turntable directly to the DISC inputs. 19 7.1 CH. INPUT: Connect to the corresponding analog audio outputs of a multi-channel source component such as a DVD-Audio or multichannelSACD player, or external multi-channel decoder. Typically, 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 2s [Ext 7.1/ 5.1] button. See Selecting Sources," below. NOTE: There is no bass-management or other processing (other than master-volume control) available to this 7.1 CH. INPUT. While the multichannel audio outputs of a DVD-Video player can be connected to these jacks, using the T 773s own Dolby Digital and DTS decoding and digitalanalog converters, via a digital connection, will usually produce superior results.

SPEAKER SETUP

Every surround-sound system requires "bass-management" to direct low-frequency content from any or all channels to the speakers best able to reproduce it. For this function to operate correctly, it is important that you correctly identify your speakers' capabilities. We use the terms "Small" and "Large" (and "Off"), but note that physical size may be irrelevant. A "Small" speaker is any model, regardless 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 surroundback 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 L/R Center Surr. L/R Surr. Back LARGE SMALL OFF LARGE SMALL OFF LARGE LARGE SMALL SMALL OFF LARGE OFF SMALL OFF SMALL SMALL OFF SMALL OFF SMALL OFF SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF LARGE SMALL OFF LARGE SMALL OFF OFF SMALL OFF OFF SMALL OFF OFF ON ON or OFF Subwoofer

LARGE LARGE

SPEAKER SETTINGS
From the OSDs main <Setup> menu select the <Speaker Settings> line using the HTR 2 remote's [ / ], and [Enter] keys. Using the [ / ] 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 773'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 773s Preset system; consequently, 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 OSDs main <Setup> menu select <Advanced Options> line using the HTR 2 remotes [ / ], and [Enter] keys. Using the [ / ] keys select main and zone listening for 5.1/2.0 or 7.1/OFF. NOTE: If 7.1 input is selected then the zone output is switched off.

ABOUT RDS

The Radio Data System (RDS) permits compatible FM A/V Receiverss to display text determined by the broadcaster. The T 773 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.

VIEW RDS TEXT

When an RDS-enabled FM broadcast is tuned, after a brief delay the RDS symbol will light in the T 773s front-panel readout and the readouts character section will show its station-name (PS) text: ROCK101, for example. Press the front-panel DISPLAY key to toggle the readout between this and the stations radiotext (RT) readout, if any, which might scroll song- or artist-name, or any other text of the stations choosing.

ABOUT USER NAMES

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.

ENTERING USER NAMES

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 a blinking box. Use the SEARCH keys to select the first character of the name (N from the alphabetic list; press either PRESET 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.
DIGITAL ABOUT DTS AND DOLBY DIGITAL SURROUND MODES DIGITAL DTS DIGITAL SURROUND
The Digital Theater System Digital Surround (simply called DTS) is a multi-channel digital signal format that can process higher data rates than with Dolby Digital. Although both Dolby Digital and DTS are 5.1 channel media formats, discs bearing the DTS symbol are thought to provide better sound quality due to the lower audio compression required. It also offers a broader dynamic, producing magnificent sound quality.
DTS - ES EXPANDED SURROUND (DTS ES)
This is a new multi-channel 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-ES 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 automatically 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.

Controls up to 8 devices. 44 function keys. Learns up to 352 commands. Records up to 44 macros with a maximum of 64 commands each. Configurable punch-through. Key illumination with programmable timeout. Upgradable. Contains pre-programmed library of NAD remote codes.
The NAD HTR 2 is ready to operate the T 773 A/V Receiver right out of the box, but it is really eight remotes in one. Each of the 8 Device Selector keys at the top of the handset can call up a new page of remotecontrol codes to be transmitted by the remaining 44 keys. You may teach codes from any infrared-remotecontrolled component, regardless 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 televisions codes to the [TV] page, and so on, but there is no required scheme: You may load any commands to any key on any page (see Learning Codes From Other Remotes, below). The HTR 2 is already preprogrammed with a full complement of commands for the T 773 A/V 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 commands are permanent: Even if you teach the HTR 2 new commands to take their place, the underlying 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 773, 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 your specific NAD-brand components you may need to load one or more different code-libraries; see Loading Code Libraries, below.

CONTROLLING THE T 773

The HTR 2 is divided into two main sections. Eight Device Selector keys at the top[AMP], [DVD,] [TV,] and so onset the handsets remaining keys to a page of commands 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 A/V Receiver. All 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 773. All of the function keys on the [AMP] Device Selector page perform T 773 functions. (The HTR 2 can also command many other NAD components, from its [DVD,] [CD,] [TUNER,] and [TAPE] pages.) It is 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 centrally, the red [AMP] Device Selector page corresponds to the red input-select labeling adjacent to the numeric keys: When the HTR 2s [AMP] Device Selector page is active, these keys select the A/V Receiver inputs. Similarly, 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 [] record key (just below the [DISP] key), until the Learn LED at the center of the HTR 2 turns steady green. Press the HTR 2s 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 2s Learn LED will flicker amber for a second or two, then turn solid green. The command is learned. Press the HTR 2s 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.

Press [SURR MODE]; the Learn LED turns amber. Press [AMP] twice; the Learn LED turns green. Press [DVD] again to exit the learning mode.

TRIGGER SETUP

The T 773s 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 a connected component or system. See your NAD audio specialist for more information.
ASSIGNING THE TRIGGER OUTPUT
From the OSDs main <Setup> menu, select the <Input Settings> item using the remote's [ / ] and [ / ] keys; use the same keys to toggle the <Trigger 1 or 2, 1 +2, MAIN, or ZONE> line. One can select the video input (DVD, SAT, VCR, or VIDEO 4-6) you wish to assign to the TRIGGER 1 output. Furthermore the selected Trigger 1 or 2 can be assigned to the main room, zone, or both locations. See ADVANCED OPTIONS to assign MAIN and/or ZONE control. Select <Save and Exit> to store the trigger assignment.

NAD T773/T763 RECEIVERS UNDERGO LATEST UPDATES
NAD Electronics, leaders in innovative audio and video development, now feature the latest in video up-conversion in their flagship classic T773 and T763 A/V Home Theatre receivers. The latest up/down conversion with output via Component connection, means analogue sources such as Composite and S-Video can now be converted to Component. These models also incorporate NADs proprietary V2.0 operating system that facilitates higher levels of support for many of the T773 and T763 features, including more flexible control of the multi-zone features The T773 (7-channel 110W/ch) and T763 (6-channel 100W/ch) A/V receivers offer fully featured, flexible processor/preamplifier/tuner sections with formidable multichannel amplifiers. Aside from both units supporting all of the present processing modes such as Dolby Digital, Dolby Digital EX, DTS, DTS EX Matrix, DTS ES 6:1 and Dolby Pro-Logic, they also feature the latest Dolby Digital IIx and Dolby Pro-Logic IIx decoding circuitry. Both of these formats increase versatility in processing stereo and 5.1 signals into 6.1 or 7.1 channel outputs. These latest decoding formats also allow you to choose Movie or Music Modes and tailor the listening experience to the source material. NADs Enhanced Ambience Recovery System (EARS) circuitry is also featured in the T773 that provides a proprietary stereo to 5.1 channel algorithm and Matrix 7.1.
NADs V2.0 software upgrade enables Quick Start A/V presets for the five most common speaker setups, including 7.1 large speakers, 7.1 small speakers, 5.1 large speakers, 5.1 small speakers and 4.1 small speakers. There are five independent Scenario Presets, which can store speaker level and tone control settings for instant recall, making it easier to customise your system for different types of program material. Supporting a philosophy of investing in technology where it truly makes an appreciable sonic difference, NAD employ high quality 192kHz/24 bit DACs and other critical components that are selected on the merit of their musical sound quality. Particular attention is given to the front main channels, which are fed from a specially selected two-channel DAC for the best possible sonic performance with CDs and uncompressed PCM recordings. For 2-channel signals Dolby Pro-Logic IIx Music Mode features three additional user controls: Dimension, Centre Width and Panorama, while Dolby Digital EX is now selectable from the front panel and the remote. Both models offer the latest surround sound DSP algorithms together with several proprietary modes. To create a virtual transparent path for SACD and DVD-audio sources, the 7.1 input has only the main volume control and an output buffer stage in the circuit. Similarly, to maintain purity, the analog stereo inputs are not digitalised unless a surround mode is engaged this means the best quality sound is available from CD, tuner and other 2-channel stereo sources. NADs PowerDrive circuitry is designed to extract maximum performance under varying power output and load conditions, and with the T773, the output power is provided by two Holmgren toroidal transformers, one dedicated to the left, centre and right main channels, the other covering the remaining four surround channels. Both models include powerful Multi-zone features including a second zone Multisource audio/video pre-amp, complete with independent source and volume control that could address a second 7.1 power amplifier set-up. With direct pre-
amp outputs for connecting to an external amplifier, two subwoofer outputs together with a multitude of additional connections to accommodate the most complex switching and custom installation needs, the NAD T773 and T763 are suited to the most demanding Home Theatre and media living requirements. There is both a Variable and Fixed second zone volume control, whereby when Variable is selected the second volume control can be adjusted via the second ZR2 remote control. The Fixed setting is selected when a separate amplifier with its own volume control is being used for the second zone. The zone setting menu also allows for a 5.1 surround sound set-up in the main zone and a 2-channel music system in a second zone. You can also assign 12-volt trigger outputs to compatible components such as your controller to lower/raise screens etc. Both the T773 and T763 have an abundance of audio, video and control connections including six sets of audio and video inputs, including S-Video and Composite, while Component Video is handled by three sets of inputs and one output. Each of the receivers incorporate six user assignable digital inputs (four coaxial, two TOS link), and two digital outputs (one coaxial, one TOS link) to manage direct digital sources. Both models feature NADs HTR-2 remote control that can control up to eight different components and can be programmed with up to 64 individual commands via a macro function. For example, all the commands required for watching a DVD are executed automatically by the HTR-2 Macro function. For custom installations, IR inputs and outputs plus a RS232 port allow for easy integration of the T773 to a variety of advanced control systems. The NAD T773 and NAD T763 are all covered by a nationwide two-year warranty.

About NAD NAD entered the audio industry in 1972 and the companys philosophy is equally relevant today as it was then to design and develop great sounding audio equipment. Over the years NAD has received many awards and accolades making it somewhat of a legend in the hifi world. While featuring the latest stylish finish titanium for several of the models, many of the companys products continue to have the simple charcoal grey front panel of the classic NAD component look. A design that is unassuming, however, when it comes to performance NAD products are anything but unassuming. Released for and on behalf of Audio Products Group Pty Ltd by High Profile Communications.
