THANK YOU FOR CHOOSING NAD.

The T 747 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 747 delivers a range of genuinely useful options for surround sound and stereo listening, using powerful digital signal processing and superbly accurate digital-audio circuitry. However, we have also been careful to ensure that the T 747 is as musically transparent and spatially accurate as possible, incorporating much of what we've learned from a quarter century's experience designing audio, video and home-theater components. As with all our products, NAD's "Music First" design philosophy guided the T 747's 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 NADT 747, and get the most from this powerful and flexible home-theater component.

One more thing: We urge you to register your T 747 ownership on the NAD Worldwide Web site:

http://NADelectronics.com/warranty

For warranty information contact your local distributor.

WHAT'S IN THE BOX

Packed with your T 747 you will find

An AM loop antenna
A FM lead-type antenna
A detachable AC power cord
The AVR 3 remote control with two AA batteries.
- The ZR 5 zone remote control with 3V CR2025 battery.
This owner's manual.

SAVE THE PACKAGING

Please save the box and all of the packaging in which your T 747 arrived. Should you move or otherwise need to transport your T 747, 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!

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 23 feet/7 meters, between the T 747's front panel and your primary listening/viewing position—this will ensure reliable infrared remote control communications. The T 747 generates a modest amount of heat, but nothing that should trouble adjacent components.

It is especially important that sufficient ventilation be provided. If you are contemplating on locating the T 747 within a cabinet or other furniture, consult your NAD audio/video specialist for advice on providing adequate airflow.

DEFAULT SOURCE SETTINGS

The following table lists the default SOURCE settings. Note that the Audio Input settings show both digital and analog audio input. Digital input will always take precedence over analog audio input even if both are present.

Source	Audio Input	Video Input
Source 1	HDMI 1/ Audio 1 IN	HDMI 1
Source 2	Optical 1/ Audio 2	Component Video Input 2
Source 3	Optical 2/ Audio 3	S Video 3
iPod	Audio 4	S-Video 4
Source 5	Coaxial 1/Audio 5 IN	Video 4
Multi	7.1 Ch. Input	Component Video Input 3
Front	Optical Front Input/ Audio Front Input	S-Video Front Input
MP	MP Front Input
Tuner

For Video output, select the highest quality video format available on your TV/Monitor and utilize this for your Monitor OUT connection from the T 747 to the TV/Monitor. In most cases, this would be HDMI but for other TV/Monitor without HDMI input, the best quality connection could be Component Video, S-Video or Composite video input.

To modify the above default settings and for a better understanding of source setting and combinations, please refer to the item about "SOURCE SETUP" in the "USING THE 747 - SETUP MENU" segment of the "OPERATION" section.

On the other hand, if your source has two output jacks indicative of stereo output, insert both jacks into the T 747's corresponding Front "L" and "R (MONO)" input to achieve stereo output as well.
12 FRONT MP/MIC INPUT: Connect your MP 3's standard stereo phone jack to this input. This is also same input where the supplied microphone is connected for speaker auto calibration. Refer also to the item about AUTO CALIBRATION under the USING THE T 747 - MAIN MENU segment of the OPERATION section.

REAR PANEL

ATTENTION!

Please make sure that the T 747 is powered off or unplugged before making any connections. It is also advisable to power down or unplug all associated components while making or breaking any signal or AC power connections.

1 DIGITAL AUDIO IN/OUT (COAXIAL 1-2, OPTICAL 1-2): Connect to the corresponding optical or coaxial S/PDIF-format digital output of sources such as CD or BD/DVD players, HDTV or satellite tuners and other components. Coaxial and Optical digital input association is configurable via the Source Setup item of the Setup Menu OSD.
DIGITAL AUDIO OUT (OPTICAL, COAXIAL): Connect the optical or coaxial digital OUT port to the corresponding S/PDIF digital input of a compatible device such as CD recorders, receivers, computer soundcard or other digital processors.
2 MONITOR OUT (S-VIDEO,VIDEO): 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.
3 AUDIO 1 IN/OUT,VIDEO 1 IN/OUT, S-VIDEO IN/OUT: Connect AUDIO 1 IN/VIDEO 1 IN/S-VIDEO 1 IN to the analog audio/video output port of a recording component such as a video cassette recorder, DVD recorder or to an outboard audio/video processor. Connect AUDIO 1 OUT/VIDEO 1 OUT/S-VIDEO 1 OUT to the recording component's corresponding analog audio/video input port.

The signal present at AUDIO 1 OUT/VIDEO 1 OUT/S-VIDEO 1 OUT port is dependent upon the current active SOURCE. There will be no output at AUDIO 1 OUT/VIDEO 1 OUT/S-VIDEO 1 OUT when Source 1 is the selected source input. This prevents feedback through the recording component thereby preventing possible damage to your speakers.

4 AUDIO 2-4/VIDEO 2-4, S-VIDEO 2-4: These comprise the T 747's other principal inputs. Connect these S-Video, composite video, and analog stereo audio input ports to the corresponding output ports of source components such as DVD players and HDTV/satellite tuners. Refer also to "AUDIO 1 IN/OUT,VIDEO 1 IN/OUT, S-VIDEO 1 IN/OUT" discussion above.

5 ZONE 2: Sends zone selected video output source to the corresponding video input of another zone. Use high quality patch cables to reduce noise pickup over long distance runs. Refer also to the item about ZONE 2 CONTROLS under the USING THE T 747 - MAIN MENU segment of the OPERATION section.
6 HDMI (HDMI 1-4, HDMI MONITOR OUT): Connect HDMI inputs to the HDMI OUT connectors of source components such as DVD player, BD player or HDTV satellite/cable box. Connect the HDMI Monitor OUT to a HDTV or projector with HDMI input.

WARNING

Before connecting and disconnecting any HDMI cables, both the T 747 and the ancillary source must be powered OFF and unplugged from the AC outlet. Failure to observe this practice may cause permanent damage to all equipment connected via HDMI sockets.

7 COMPONENTVIDEOINPUT1-3,COMPONENTVIDEOOUT:

Connect the Component Video IN 1-3 inputs to Component Video outputs from compatible source components, typically a DVD player and terrestrial or satellite HDTV tuner. Connect Component Video OUT to the Component Video input of a compatible video monitor/TV. Be sure to observe consistency in connecting the Y/Pb/Pr jacks to the corresponding sources/inputs. The routing of the component video inputs is fully configurable via the Setup Menu.

The T 747's component video inputs and outputs are fully wideband and compatible with allowable HDTV formats.

8 7.1 CH INPUT: Connect to the corresponding analog audio output ports of multichannel source components such as a DVD-Audio or multichannel-SACD player or external multichannel decoder (disc copy protected formats only allow analog signal transfer). 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 Multi (7.1 Channel Input is defaulted to this Source setting).

There is no bass-management or other processing (other than master-volume control) available to this 7.1 Channel Input. While the multi-channel audio outputs of a DVD-Video player can be connected to these jacks, using the T 747's own Dolby Digital and DTS decoding and digital-analog converters via a digital connection will usually produce superior results.

9 AUDIO PRE-OUT:The Audio PRE-OUT makes it possible to use the T 747 as a pre-amplifier to external power amplifiers for some or all channels. Connect FRONT L, FRONT R, CENTER, SURR R, SURR L, SURR-BL and SURR-BR to the respective channel input of a power amplifier or an amplifier driving the applicable speakers.

Unlike the full range channels, there is no power amplifier built into the T 747 for a subwoofer. Connect the SUBW output to powered ("active") subwoofer or to power amplifier channels driving a passive system.

10 FM, AM ANTENNA INPUT: Connect the supplied lead-type FM antenna to the FM antenna input. Extend the lead. Experiment freely with your antenna placement and orientation until you get the clearest sound and lowest background noise. Fix the antenna in the desired position by using thumb tacks, push pins or any suitable means.

The AM loop antenna supplied with the T 747 (or a suitable replacement) is required for AM reception. Open the clip terminal lever; insert the wire making sure to match the color-coded (white and black) ends of the wire to that of the terminal and close the lever 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.

Refer also to the "LISTENING TO AM/FMRADIO" segment of the "OPERATION - LISTENING TO AM/FM/XM RADIO" section.

11 XM MODULE INPUT (120V version only): Connect XM radio cable to this socket. Follow the instructions that came with your XM radio. With XM radio, there are more than 100 channels of music, news, sports, comedy, talk and entertainment. You will find that the coverage is continent wide.

NOTE

The external XM radio is not supplied with your T 747.

12 upload (MCU, HDMI), RESET: The MCU, HDMI and RESET tact switches are used for software program updates (if any) in combination with the RS232. Your custom installer or dealer can assist you in the proper upgrade and setup of your T747.

13 IR IN/IR OUT 1-2: These mini-jacks accept and output remote-controlled codes in electrical format, using industry-standard protocols, for use with "IR-repeater" and multi-room systems and related technologies.

IR IN: This input is connected to the output of an IR (infrared) repeater (Xantech or similar) or the IR output of another component to allow control of the T 747 from a remote location.

IR OUT 1, IR OUT 2: Both IR OUT 1 and IR OUT 2 have dual-features - they can act as an infrared command repeater or stand alone as IR OUT. Connect the T 747's IR IN to the IR OUT of ancillary equipment. Connect also the T 747's IR OUT 1 (or IR OUT 2) to another equipment with IR IN feature. With this setup, the T 747 acts as an "IR-repeater" allowing the equipment connected to the T 747's IR IN control or command of the other equipment linked to the T 747's IR OUT 1 (or IR OUT 2).

As a stand alone IR OUT, connect IR OUT 1 (or IR OUT 2) to the IR IN of an ancillary equipment. Direct the ancillary equipment's own remote control to the T 747's infrared receiver to command or control the linked unit.

14 +12V TRIGGER OUT: The +12V TRIGGER OUT is used for controlling external equipment that is equipped with a +12V trigger input. Connect this +12V TRIGGER OUT to the other equipment's corresponding +12V DC input jack using a mono cable with 3.5mm male plug.

MAIN MENU

The Main Menu contains the menu options for "Listening Mode", "DSP Options", "Tone Controls", "Zone 2 Controls" and access to "Setup Menu".

To navigate through these Main Menu options and their sub-menu selections, please refer to above section about "DISPLAY THE OSD" and "NAVIGATING THE OSD AND MAKING CHANGES".

LISTENING MODE

The T 747 offers distinct listening modes, tailored for different types of recording or program material. With a two-channel (Stereo) source, the following listening modes can be selected:

STEREO

All output is directed to the front left/right 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 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 as recorded. Multi-channel digital recordings (Dolby Digital and DTS) are reproduced in "Stereo Downmix" mode via the front left/right channels only as Lt/Rt (left/right-total) signals.

Dolby Virtual Speaker technology creates a highly compelling 5.1-channel listening experience from as few as two speakers, making it an ideal entertainment solution for locations where space for multiple-speaker setups is limited.

Dolby Virtual Speaker models the sound of a playback system into two different listening environments, based on acoustic measurements of real rooms:

DVS Reference is a small, well-damped room appropriate for both movies and music-only recordings.

DVS Wide is a larger room, more like a concert hall or movie theatre.

PRO LOGIC IIx

Dolby Pro Logic IIx processes both stereo and 5.1 signals into a 6.1 or 7.1 channel output. At Dolby Pro Logic IIx, you can choose PLIIx Movie or PLIIx Music modes to tailor your listening experience to the source material. Dolby Pro Logic IIx surround processing 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. For two channel signals, PLIIx Music mode also features three additional user controls - Dimension, Center Width, and Panorama. See also section about "ADJUSTING LISTENING MODES" below.

The following chart shows the channels available assuming they are enabled in the "Speaker Configuration" menu.

Listening Mode Two-Channel Sources	Active Decoded Output Channels
	6.1 Speaker System	7.1 Speaker System
PLIIx Music PLIIx Movie	Front (left & right), Center, Surround (left & right), Back Surround, Subwoofer	Front (left & right), Center, Surround (left & right) and Back Surround (left and right) and subwoofer

USING THE T 747 - MAIN MENU

NEO:6

Two-channel recordings, whether stereo or surround-encoded, are reproduced with Neo:6 surround with output to front left/right, center and discrete left/right surround channels plus subwoofer (assuming these are present in the current "Speaker Configuration"). The T 747 provides two DTS NEO:6 variations - NEO:6 Cinema and NEO:6 Music. See also section about "ADJUSTING LISTENING MODES" below.

EARS

Two-channel recordings, whether stereo or surround-encoded, are reproduced with proprietary NAD surround processing with output signals to the front left/right, center and discrete left/right surround channels, plus subwoofer (assuming these are present in the current "Speaker Configuration"). 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 remain 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. Its virtues include realistic, stable "front-stage" sonic imaging and spacious but unexaggerated ambient "virtual acoustics" that remain faithful to the original recording.

ENHANCED STEREO

All recordings are reproduced in stereo via the maximum speaker complement configured in the current "Speaker Configuration". Enhanced stereo can be useful for maximum volume from all channels or for multispeaker background music (cocktail party) listening. For this mode, Front, Center, Surround and Back speakers can be turned ON/OFF as desired.

7 CH STEREO (7 CHANNEL STEREO)

Two-channel recordings are reproduced with output signals to the front left/right, center, discrete left/right surround and back surround left/right channels, plus subwoofer (assuming these are present in the current "Speaker Configuration"). The Back Surround (left/right) output level is -3 dB lower than the other channels.

ANALOG BYPASS

All analog signals remain in the analog domain without analog-to-digital conversions. At Analog Bypass, the DSP circuitry is bypassed but full tone control functions remain. "Bass management" or "Speaker Setup" are also not in effect as these are DSP functions.

ADJUSTING LISTENING MODES

Several of the T 747's listening modes have one or more selectable variations and adjustable parameters that you can modify to suit your personal preferences. At Listening Mode menu, use a combination of the [▲/▶] and [▲/▼] keys to navigate and effect desired settings.

NOTE

Listening Mode parameter changes are maintained when you change listening modes. You may also save a modified Listening Mode for easy recall by saving it to a Preset (See "A/V PRESETS" below under Setup Menu discussions).

PRO LOGIC IIx

PLIIx MOVIE is optimized for film soundtracks.

PLIIx MUSIC for music recordings.

Center Width (0 to 7): Modifies the "hard-centeredness" of the center image, by gradually mixing mono center content to the Front left/right speakers as well. A setting of 0 retains the center-channel-only default while a setting of 7 yields a fully phantom center channel.

Dimension (-3 to +3): Adjusts front-rear emphasis of the surround effect independently from the relative channel levels.

Panorama (On/Off): Adds a "wrap around" effect by extending some stereo content into the surround channels.

NOTE

Pro Logic IIx mode will decode as Pro Logic II mode when the "Back" surround speakers are set to "Off" from "Speaker Configurations" menu. Refer also to the item about "SPEAKER CONFIGURATION" under the "SPEAKER SETUP" segment of "OPERATION - USING THE T 747 - SETUP MENU" section.

NEO:6

NEO:6 Cinema is optimized for film soundtracks.

NEO:6 Music for music recordings.

Center Gain (0 to 0.5): Adjust for better center image in relation to the surround sound channels.

DSP OPTIONS

DSP Options has the feature "Lip Sync Delay" whose function is to match any delay that may occur in the picture relative to the audio.

By varying "Lip Sync Delay" from 0ms to 120ms, one can delay the audio output in order to synchronize it with the video image.

Another DSP option is the "HDMI Audio to TV". This option is applicable only when using an HDMI source and a video output display that is HDMI-capable. "HDMI Audio to TV" setting can be set to either "On" or "Off".

On: When set to "On", audio will be available via both the HDMI-capable TV's own speakers and the T 747's speakers.

Off: When set to "Off", audio will only be available via the T 747's speakers. There will be no audio at the HDMI-capable TV's own speakers.

TONE CONTROLS

"Tone Defeat" gives one the choice of varying or completely bypassing the tone control section of the T 747. If "Off" is selected, the Tone Control circuits are active. Select "On" to bypass the Tone Controls effectively defeating the effect of the tone control circuits.

The T 747 has two Tone Control levels - Treble and Bass. Bass and Treble controls only affect the low bass and high treble leaving the critical midrange frequencies free of coloration.

These controls allow one to tweak on-the-fly, the frequency response of the source. Use the [ / ] keys to adjust Treble and Bass within the range ± 10 dB.

ZONE 2 CONTROLS

The Zone feature allows one to simultaneously listen to an active Source of the T 747 that is different from the currently selected Source.

Power

Select "On" to activate the Zone 2 function. If "Power" is set to "Off", the Zone 2 feature is deactivated or powered off.

Source

When activated, Zone 2 can be allocated a Source input by selecting through the following inputs – All enabled Sources (Source 1-3, iPod, Source 5, Source 6), Multi, Front, MP and Tuner. Select the particular Source input to be associated to the Zone 2 output. As long as the associated Source input is active, it will continuously be available at ZONE 2 OUT regardless of the Main Zone settings. For example, while the T 747 is at Source 1 mode, you can set the Zone 2 Controls"Source"item to "Source 2", the active Source 2's audio and video output will be directed to ZONE 2 output port in the rear panel even though the T 747 is at Source 1 mode.

You can then feed the ZONE 2 OUT jacks to another amplifier or receiver that maybe located in another area of your home or building. With your separate amplifier or receiver selecting the fed signal and with speakers connected, you can then enjoy the zone selected source's audio/video signal.

Volume

"Volume" refers to the adjustable secondary Zone 2 Volume level that can be increased or decreased depending upon its settings. "Volume" can either be set to "Fixed" or "Variable". This is applicable only if the selected ZONE 2 Audio Output port is the ZONE 2 VAR. If ZONE 2 FIX is the selected Zone 2 audio output port, the "Volume" settings in this Zone 2 Controls OSD will not apply.

Fixed: If "Volume" is set to "Fixed", you can set a desired preset dB level and thereafter the zone's volume level can be varied via the volume control of the separate amplifier it is fed into.

Variable: When set to "Variable", the Zone 2 Volume level is directly adjustable using [VOL / ] keys of ZR 5 remote control or can be varied via the volume control of the separate amplifier it is fed into. At "Variable" setting, you have to exit from the Main menu OSD for you to use ZR 5's [VOL / ] buttons in adjusting the Zone 2 volume level.

NOTE

When Zone 2 is activated, "Z2:_" (__ corresponds to the selected Source) is displayed in the VFD when "Zone 2 Source" is selected at either "Line 1" or "Line 2" of the "Front Panel Display Setup" menu (See "Front Panel Display Setup" below under Setup Menu discussions). If the Zone function is not turned OFF, the same zone display settings will still be shown in the VFD even though the T747 is powered OFF. Turn OFF the Zone function either by pressing ZR 5's OFF button or setting "Power" to "Off" at the Zone 2 Controls menu.

USING THE T 747-SETUP MENU

SETUP MENU

The Setup Menu allows one to customize the operation of the T 747 to the ancillary equipment used in one's specific AV system. Unless your system exactly matches the factory defaults, you will need to use the Setup Menu to configure the settings of your T 747.

At Setup Menu, the following are configurable - A/V Presets, Source Setup, Speaker Setup, Amplifier Setup, Trigger Setup, Listening Mode Setup, Front Panel Display Setup and Video Setup.

To navigate through these Setup Menu options and their sub-menu selections, please refer to above section about "DISPLAY THE OSD" and "NAVIGATING THE OSD AND MAKING CHANGES".

A/V PRESETS

The T 747's simple but powerfully flexible system of "Presets" allows you to customize virtually every aspect of your audio-video playback, and recall them with a single key-press. The parameters "Listening Mode", "DSP Options", "Tone Controls", "Speaker Setup" and "Front Panel Display Setup" settings are stored together as a Single Preset.

You might create one Preset optimized for pop music and another for classical. One more Preset can be set up to recall each family member's favorite setting or one for fully cinematic home-theater playback and yet another one for late-night movies, with each Preset fine-tuned to a particular scenario or preference.

CREATING PRESETS

Creating a Preset consists simply of storing a complete set of the parameters set forth in the "Listening Mode", "DSP Options", "Tone Controls", "Speaker Setup" and "Front Panel Display Setup" configurable through "Setup Menu".

Go to "A/V Presets" to save a collection of said parameter settings to a Preset. Select a Preset number and you can then selectively include in this particular Preset number any of the above-mentioned parameter settings by choosing "Yes". If you decide not to include in the particular Preset a certain parameter setting, select "No".

Now in order to save the settings chosen for the particular Preset number, scroll down to "Save Current Setup to Preset" and press the [▶] key. If you chose to load instead the default settings, scroll down to "Load Defaults to Preset" and press the [▶] key to restore the default settings.

In addition to the parameter settings, the Preset label itself can be assigned a new name. This new Name will be shown in the VFD as well as on the OSD.

To rename the Preset label, scroll to "Name" and press [▶] to go the character. Then, press [▲/▼] to pick and select through the alphanumeric selections. Press [▲/▶] to move to the next character or back to the previous character and at the same time save the changes done on the current character.

S-Video 1, S-Video 2, S-Video 3, S-Video 4, S-Video Front
Composite 1, Composite 2, Composite 3, Composite 4, Composite Front

Another option is "Off" wherein the particular Source is prompted not to select any Video input.

A/V Presets

A particular Source can be assigned a stored Preset. The parameters set up in the selected Preset number will be adopted into the particular Source it is assigned (Please refer to the separate section on "A/V PRESETS" above for further understanding of Preset settings).

Scrolling to "A/V Presets" and by pressing [▶] and then [▲/▼] keys, a Source could be assigned a Preset number ranging from Preset 1 to 5.

If it is desired not to assign the particular Source a Preset setting, select "None".

Trigger Out

The Trigger Out for a particular Source is dependent on the configurations done in a separate menu on Trigger Setup (See "TRIGGER SETUP" below). If Trigger output is assigned to "Source Setup" in the separate "Trigger Setup" menu window, +12V will be available at +12V TRIGGER OUT port whenever a Source with "Trigger Out" set to "Yes" is recalled.

Another option is "None" whereby the particular Source is not assigned any Trigger Out.

SOURCE SETUP (TABLE VIEW)

The Source Setup (Table View) reflects the settings made in the Source Setup (Normal View) menu. All the Source settings are summarized and displayed in tabulated form in the Source Setup (Table View).

Navigating through the Source Setup (Table View) via a combination of [ ] and then [ / ] keys, one will have the benefit of directly changing the settings for "Audio, Video, Preset, Trigger and Name" without going back to the Source Setup (Normal View) menu. Note that to effect a change in the settings, you have to press [ENTER]. Toggle [ENTER] also to enable or disable a Source.

ABOUT FIRST TIME SETUP OF NAD T 747

The T 747 includes a high performance video processor that can upscale Standard Definition (SD) video to High Definition (HD) video. The HD video is only available on the HDMI (up to 1080p resolution) or Component Video (up to 1080i resolution only) output.

If you are using an HD capable TV, you should connect either HDMI or Component Video, not both. All SD sources will be upscaled to HD over these HD connections. Be sure your TV is HD capable before selecting an HD resolution. Note that the default SD is backward compatible with non-HD sets.

For the On Screen Display (OSD) to be shown at your connected TV, set your T 747 to the Source number that corresponds to your TV's signal type:

Source 1: defaulted to HDMI Monitor OUT

Source 2 : defaulted to Component Video Monitor OUT

Source 3 : defaulted to S-Video Monitor OUT

These default settings can be changed, but should be used to get started. It must be noted from the above that with Source 1 defaulted to HDMI, the OSD will only be available via HDMI Monitor OUT when at Source 1. Select Source 2 or other enabled Source numbers (except Source 1) for the OSD to be available at Component Video, S-Video or Video (Composite) Monitor OUT.

iPod SETUP

The iPod Setup menu allows you to preset the following associated settings when iPod is the selected source:

Enabled: Select "Yes" to default Source 4 to iPod mode or "No" for Source 4 to be an assignable source input.

Auto Connect: Select "Yes" to automatically enable and connect the iPod player docked in the linked NAD iPod docking station when Source 4 (the default iPod source allocation in the T 747) is selected. Select "No" if you do not want for the iPod connection automatically connected.

Menu Timeout: Set the time for the OSD to revert to the "Now Playing" display when the iPod menu has been left idle (no scrolling or navigation being done) for the specified time out time. For the "Now Playing" OSD to be shown, there should be a song paused or being played before going to the iPod menu. You can set the "Menu Timeout" between the range 5s to 60s at 5s increments. If you do not want for the menu to timeout, select "Off".

Audiobook Speed: Set the playback speed with the following options - Normal, Fast and Slow. Note that for"Audiobook Speed"to be available in the menu, an iPod player must be docked in the linked NAD IPD model.

SPEAKER SETUP

After connecting all ancillary sources and other combinations, the Speaker Setup menu will guide you on how to manage and setup your speakers in order to achieve optimum sound acoustics in your listening environment. The following are the Speaker Setup Menu sections.

USING THE T 747 - SETUP MENU

AUTO CALIBRATION

It has been shown that many, if not most, surround sound systems are not accurately setup and calibrated. To be done properly, calibration requires special knowledge and instrumentation that the average person probably doesn't possess.

The Auto Calibration featured in T 747 uses a microphone, along with sophisticated digital electronics built into your T 747, to automatically setup and calibrate the T 747 to the exact speakers and speaker placement of your own unique Home Theatre.

The following parameters are automatically measured and adjusted accordingly.

• Noise Level: Check noise level relative to each speaker and subwoofer.
• Number of Speakers : Speaker configuration is detected including number of surround speakers and whether a subwoofer and center channel is connected.
• Speaker Distance: Accurately set the appropriate distance of each speaker position as well as the subwoofer with respect to the microphone position.
• Speaker Level and Size: T 747 crossover is set based on each channel's signal handling capability and the subwoofer crossover is automatically set. SPL (Sound Pressure Level) of each speaker is matched with respect to the microphone position.
• Equalization: Adjust tonal quality (bass/treble level) for each speaker. This applies to all sound fields and for each speaker.

This is a one-time set up, unless speakers are moved or changed, in which case the calibration should be performed again.

MEASUREMENT IS THE FIRST STEP

Connect the microphone jack into the front panel's MP/MIC input. Place the supplied microphone in the listening position at about the same height as your listening ears. The microphone has a threaded insert at its base that makes possible for it to be mounted on a tripod.

The sound at your main listening position is setup using the supplied microphone. Depending upon the availability of speakers, you can select either 7.1 or 5.1 setup. Upon selection of either 7.1 or 5.1, the auto calibration starts – refer to the OSD as auto calibration steps through each measurement parameter.

A special test tone is sent to each speaker and the data is memorized by the T 747. The duration of setup may take some time depending on the number of speakers. After the measurements, the T 747 calculates the ideal system response for your particular room and speaker setup. If some inconsistencies or discrepancies are detected during the setup, the process maybe interrupted or the problem is shown in the particular setup window. A notice screen is correspondingly displayed. After following and undertaking the displayed instructions, re-start the Auto Calibration setup again. When the measurements are finalized, the ideal system response is calculated for your particular room and speaker setup.

NOTES

• Auto calibration is possible only for a 7.1 or 5.1 speaker configuration. For other speaker configurations, like a 2.1 setup, you have to manually set them up by referring to the guidelines below for Speaker Configuration, Speaker Distance and Speaker Levels.
• The test tone emitted during measurement is loud. This maybe bothersome for you and may affect as well your other household members and even your neighbor.

ABOUT EQUALIZATION

Equalization is one of the parameters automatically adjusted when the Auto Calibration feature is initiated. If after Auto Calibration, the resulting equalization effect does not suit your taste or preference, you have the option to turn off such equalization effect. Below is the procedure on how to turn off equalization.

1 Ensure that auto calibration is completed. Equalization cannot be turned ON or OFF if auto calibration is not performed and completed.
2 Using the AVR 3 remote control and with Device Selector set to AMP page, direct the AVR 3 to the T 747's remote sensor.
3 Press and hold AVR 3's TEST button until the upper line of the VFD shows "Adjusting EQ" and the lower line "OFF"; equalization is now turned OFF.
4 If you decide to turn ON again the calibrated equalization effect, press and hold AVR 3's TEST button until the upper line of the VFD shows "Adjusting EQ" and the lower line "ON"; equalization is now turned back ON.

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 "S" (Small), "Large" and "Off", but note that physical size may be irrelevant.

• A "S" (Small) speaker is any model, regardless of physical size, that lacks significant deep-bass response, that is, below about 150Hz .
• 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 "Back" setup item to "Off".

The Speaker 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 747's Preset system. Consequently, multiple speaker settings can be stored for easy recall as different types of recordings or listening modes require.

Speaker Configuration can be managed and adjusted by pressing a combination of [ ] and then [ / ] keys. Set "Front", "Center", "Surround" and "Back" to "Large", "Small" (Small 60 Hz up to Small 150 Hz) or "Off" as your subsystem's speakers require.

Set "Subwoofer" to "On" or "Off", selecting "On" only if you have a subwoofer connected to the SUBW output jack. If the "Subwoofer" is set to "Off", "Front" speaker will automatically be set to "Large".

SPEAKER LEVELS

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 a subwoofer it establishes a correct relationship between the volume of the subwoofer and the other speakers, and thus of low-frequencies (bass) to other sonic elements.

USING AN SPL METER

It is quite practical to perform the T 747 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.

The SPL meter should be placed at the primary listening position, at approximately the height of the seated listener's head. A 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 one end) pointing straight up toward the ceiling (not toward the speakers) and ensure that "C" 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.

USING THE T 747 - SETUP MENU

SETTING SPEAKER LEVELS AT TEST MODE

While at "Speaker Levels" menu, press the AVR 3 remote's "Test" key activating the T 747's Speaker Levels balancing test signal. You will hear a Test tone. To test each channel, use AVR 3's [/] keys to move up or down the speaker channels. If you do not hear the Test tone, check your speaker connections or "Speaker Configuration" settings.

To adjust the level of a particular channel, press [ ] to display "^v" on the extreme right of the selected channel. Adjust the selected channel to desired level by pressing [ / ] - the level will change by 1 dB increments up to ± 12dB . After adjusting a channel, press [4] to effect the change in level. Press [ / ] to select the next channel for adjustment.

You can exit "Test" mode at any time by pressing the [ ] key, bringing you back to "Speaker Setup" menu.

NOTES

All speakers must be in their final locations before level-setting.
- If 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.
- 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 747's Subwoofer output. Final subwoofer-level adjustment "by-ear", using music and film sound material, is frequently 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 a subtle but important refinement of your setup. Informing the T 747 of the loudspeaker-to-listener 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

While at "Speaker Distance" menu, use the [▲/▼] keys to individually set Front Left, Center, Front Right, Surround Right, Back Right, Back Left, Surround Left and Subwoofer to the distance measuring from your principal listening position to the front surface of their corresponding loudspeakers. Distance can be set up to 30 feet or 9 meters.

Distance can be displayed as feet or meters selectable at the "Unit of Measure" item.

ADJUSTING THE VOLUME

In addition to the front panel VOLUME knob, use the AVR 3's [VOL / ] to adjust the volume of the T 747, raising or lowering all the channels together. A momentary keypress will change the master volume by 1 dB increments. If you hold down [VOL / ] the volume change will "run-on" until the key is released.

Since recordings vary considerably in overall average level, there is no imperative to listen at any particular volume setting. A setting of -20 dB may sound "as loud" from one CD or DVD as -10 dB does from another.

The T 747 will power-up from Standby mode at whatever master volume setting was last used; however, if the prior setting was greater than -10 dB, the T 747 will power up at -10 dB. This prevents inadvertently beginning a session at excessive volume.

MUTING THE SOUND

Use the AVR 3's "Mute" key to silence all channels completely. Muting is always available regardless of the source or listening mode selections.

NOTES

• Changing input or listening-mode selections does not release muting.
• Adjusting the volume level via the AVR 3 or the front panel volume knob will automatically release the mute function.

AMPLIFIER SETUP

If the surround back speakers are not used in the main zone, their surround back amplifier channels could be assigned for Main Back or Zone 2.

The Surround Back amplifier is configurable through the following settings

• Main Back: Assign as surround back speakers.
• Zone 2: Assign the surround back amplifier channels to supply Zone 2 speaker level outputs from the surround back speaker terminals.

IMPORTANT NOTICE

If "Back Amp" is set to Zone 2, it is not possible to select "7.1" in the Auto Calibration menu since the surround back speakers are effectively not included in the configuration anymore. Only "5.1" is selectable at this condition.

TRIGGER SETUP

The T 747 features a configurable +12V DC Trigger Output that can be used to activate a component or system it is fed into.

TRIGGEROUT

Triggers are low voltage signals used to turn on/off other compliant devices. There are three choices where +12V DC output can be assigned and these are - Main, Zone 2 and Source Setup.

Main: +12V DC is available at the assigned Trigger Out when the T 747 is at powered state.

Zone 2: When the Zone 2 is at powered state, +12V DC is available at Trigger Out.

Source Setup: If Trigger Output is linked to "Source Setup", +12V DC is available at Trigger Out whenever the particularly assigned Source is selected.

DELAY

The availability of +12V DC at Trigger OUT can be regulated. If it is desired that +12V DC is available without delay the moment Trigger OUT is linked to its assigned setting, set Delay to 0s. Otherwise, one can select through a delay time of 1s to 15s.

LISTENING MODE SETUP

The T 747 has various listening mode options and is mostly configurable. These are provided to reproduce a variety of sound effects depending upon the content of the source to be played.

LISTENING MODE

The audio format as detected by the selected Source can be automatically configured and processed through the following options:

Dolby Digital

Dolby Digital is the multi-channel digital signal format developed in the Dolby laboratories. Discs bearing the double-D 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.

A Dolby Digital audio input can be configured relative to its format.

2 Channel: If the detected audio is a 2 Channel Dolby Digital signal, you can default it to one of the following settings - PLIIx Movie, PLIIx Music, DVS Wide, DVS Reference or None.

Surround: If the detected audio is a Surround Dolby Digital signal, you can default it to one of the following settings -Dolby Digital EX, PLIIx Movie, PLIIx Music, DVS Wide, DVS Reference, Stereo Downmix or None.

None: If "None" is selected, the Dolby Digital format will follow the "Digital" setting set forth at "Other" option under this menu section. See discussion below about "OTHER".

USING THE T 747 - SETUP MENU

DOLBY DIGITAL SURROUND MODES

The following are further descriptions about the Dolby Digital surround modes.

Dolby Digital Plus

Dolby Digital Plus is the next-generation audio technology for all high-definition programming and media. Dolby Digital Plus delivers multi-channel audio programs of up to 7.1 channels and supports multiple programs in a single encoded bitstream with the maximum bit rate potential of up to 6 Mbps and the maximum bit rate performance of up to 3 Mbps on HD DVD and 1.7 Mbps on Blu-ray Disc. It outputs Dolby Digital bitstreams for playback on existing Dolby Digital systems. Dolby Digital Plus can accurately reproduce the sound originally intended by directors and producers.

It also features multi-channel sound with discrete channel output, interactive mixing and streaming capability in advanced systems. Supported by High-Definition Media Interface (HDMI), a single-cable digital connection is possible for high-definition audio and video.

Dolby TrueHD

Dolby TrueHD is a lossless encoding technology developed for high-definition optical discs. Dolby TrueHD delivers tantalizing sound that is bit-for-bit identical to the studio master, unlocking the true high-definition entertainment experience on high-definition optical discs in the next generation.

It supports bit rates of up to 18 Mbps and records up to 8 full-range channels individually with 24-bit/96 kHz audio. It also features extensive metadata including dialogue normalization and dynamic range control. Supported by High-Definition Media Interface (HDMI), a single-cable digital connection is possible for high-definition audio and video. HD DVD and Blu-ray Disc standards currently limit their maximum number of audio channels to eight, whereas Dolby Digital Plus and Dolby TrueHD support more than eight audio channels. Note that the T 747 only supports 7.1 channel.

Dolby Digital EX

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 (double-D symbol)-EX, 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.

NOTE

Please refer to the section "LISTENING MODE" at the Main Menu discussions for a description of PLIIx Movie, PLIIx Music and Stereo Downmix modes.

DTS

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.

A DTS input can be defaulted to one of the following options - DTS+NEO:6 Music, Neo:6 Cinema, Neo:6 Music, Stereo Downmix or None.

If "None" is selected, the DTS signal will follow the "Digital" setting set forth at "Other" option under this menu section. See discussion below about "Other".

NOTE

Please refer to the section "LISTENING MODE" at the Main Menu discussions for a description of Stereo Downmix and DTS NEO:6 surround modes.

OTHER

If "None" is selected above for any of the Dolby Digital, 2 Channel, Surround and DTS options or if the audio input is an analog signal, this "Other" section will manage the default audio format as per the "Digital" or "Analog" settings.

Digital: The detected digital input can be configured by way of one of the following options - 7 ch Stereo, Enhanced Stereo, EARS, Neo:6 Music, Neo:6 Cinema, PLIIx Music, PLIIx Movie, DVS Wide, DVS Reference or None.

Analog: If the audio input is an analog signal, the following are the surround modes the input can be defaulted - 7 ch Stereo, Enhanced Stereo, EARS, Neo:6 Music, Neo:6 Cinema, PLIIx Music, PLIIx Movie, DVS Wide, DVS Reference, Stereo or None.

NOTE

All these Listening Modes for "Dolby Digital", "DTS" and "Other" can be directly changed by pressing the "LISTENING MODE" button on the front panel or through the "Listening Mode" option at the Main Menu window. The chosen audio format will be reflected back to the appropriate setting at the "Listening Mode Setup".

DOLBY SETUP

Under this menu, the Dolby Digital's Dynamic Range Control can be adjusted as well as the settings for Dolby Digital Pro Logic IIx Music.

Dyn Range Ctrl (Dynamic Range Control): 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 100% , the default. Settings of 75% , 50% , and 25% progressively reduce dynamic range, making soft sounds comparatively louder while limiting the peak loudness of loud ones.

The 25% 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.

Dolby Pro Logic IIx Music: Please refer to the item about "PRO LOGIC IIx" under the topic "ADJUSTING LISTENING MODES" at the "OPERATION - USING THE T 747 - MAIN MENU" discussions above.

DTS SETUP

Under this menu, the Center Gain settings of NEO:6 Music can be adjusted. Please refer to the item about "NEO:6 Music" under the topic "ADJUSTING LISTENING MODES" at the "OPERATION - USING THE T 747 - MAIN MENU" discussions above.

DTS SURROUND MODES

The following are further descriptions about the DTS surround modes.

DTS-HD Master Audio

DTS-HD Master Audio is a technology that delivers master audio sources recorded in a professional studio to listeners without any loss of data, preserving audio quality. DTS-HD Master Audio adopts variable data transfer rates, facilitating data transfer to the maximum rate of 24.5 Mbps in the Blu-ray disc format, 18.0 Mbps in the HD-DVD format, which by far exceeds that of a standard DVD. These high data transfer rates enable lossless transmission of 96 kHz/24-bit 7.1-channel audio sources without deteriorating the quality of the original sound. DTS-HD Master Audio is an irreplaceable technology that can reproduce sound faithfully as intended by the creator of music or movies.

DTS - ES EXTENDED SURROUND ^TM (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 extended DTS-ES Surround also offers the back surround (also sometimes called the "surround centre") in reproduction, providing a total of 6.1 channels. The extended 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.

DTS-ESTM MATRIX 6.1

In this format, the additional signals of the back channel receive a 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.

Naturally, it is also possible to reproduce from a DTS 5.1 channel decoder, signals recorded in DTS-ES 6.1.

When a DTS-ES decoder processes 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:6™ 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:

DTS NEO:6 CINEMA : This method is ideal for the reproduction of movies. The decoding takes place by emphasizing the separation in order to achieve the same atmosphere with 2-channel, as with 6.1-channel sources.

DTS NEO:6 MUSIC : Mainly 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.

ENHANCED STEREO

Please refer to the same item about "ENHANCED STEREO" under the topic "LISTENING MODE" at the "USING THE T 747 - MAIN MENU" discussions above.

USING THE T 747-SETUP MENU

FRONT PANEL DISPLAY SETUP

The Vacuum Fluorescent Display (VFD) and On-Screen Display (OSD) can be shown in various ways by navigating through the parameters at the "Front Panel Display Setup" menu.

DISPLAY

Select "On" to display all applicable data or characters at the VFD. Nothing will be shown at VFD if "Temp" is selected. However at "Temp" setting, whenever any of the front panel controls or their corresponding keys in the remote control is activated, the appropriate VFD characters will be shown temporarily and then fade away.

The configurations set forth at "Front Panel Display Setup" are carried over whenever it is enabled during A/V Preset setting. Refer also to the item about A/V PRESETS under the USING THE T 747 - SETUP MENU segment of the OPERATION section.

VIDEO SETUP

This menu allows you to set the display resolution of the T 747 along with the compatible video format setting and picture setup.

VIDEO FORMAT

There are 2 options under Video format - Resolution to Display and Frame Rate.

Resolution to Display: The T 747 has the excellent ability to

upconvert standard definition video contents to high definition video signal. Depending upon your TV/Monitor's resolution capabilities, select the applicable resolution settings - Auto, 480i/576i, 480p/576p, 720p, 1080i and 1080p. When "Auto" is selected, the T 747 automatically selects the highest resolution compatible with the connected TV/Monitor.

Note that if the display is connected to Composite or S-Video Monitor OUT, the video output resolution must be set to 480i or 576i to view content.

When you change the resolution setting, you will be prompted to Save or Cancel the resolution change as per the message shown in OSD.

Press the [▶] to save the new resolution or [←] to cancel the change in resolution.

IMPORTANT NOTES

• When using component video output, a standard definition video can be upscaled only up to 1080i.
• If you inadvertently selected a resolution setting (like 1080p) that your TV/Monitor does not support, the video display will go blank. To restore video display, press [<] or turn OFF/ON the T 747.

Frame Rate: Frame rate refers to the number of frames or images that are projected or displayed per second in motion pictures, television or computer video display.

Depending upon your area and video resolution capability of your TV/Monitor, the following "Frame Rate" options are available

50Hz: setting normally for Europe and most of Asia
60Hz: setting normally for North America
24Hz: select to deliver film-like motion characteristics; available or selectable only if your TV/Monitor supports 1080p.

When the "Resolution to Display" is set to "Auto", "Frame Rate" as an option will not be available.

IMPORTANT NOTES

• The source component, the T 747 and the TV/Monitor must have the same frame rate settings. If they do not have the same settings, video output maybe distorted.
• Selectable Frame Rate for 120V version models of T 747 is limited only to 60Hz and 24Hz . If your TV/Monitor does not support 1080p, 24Hz will not appear as an option.
• For 230V version models of T 747, 50Hz, 60Hz and 24Hz are the selectable Frame Rate options. If your TV/Monitor does not support 1080p, 24Hz will not appear as an option.

PICTURE SETUP

Picture setup can be defaulted to "Normal" or "Custom". These settings can be accessed at "Video Modes" menu item of the "Picture Setup" OSD.

Select "Normal" to retain the default picture setup settings. If you would like to further improve the picture settings or adjust the parameters according to your preference, set "Video Modes" to "Custom". The following parameters can be adjusted at "Custom" setting

Brightness: Adjust overall brightness of the video display.

Contrast: Adjust bright areas (white level) of the video display.

Color: In combination with brightness and contrast levels, adjust the color level to suit your preference. Set the level so that the colors look strong but still natural, not overdone.

MPEG Noise Reduction: This setting addresses video distortion like video noise and blocking artifacts. Set MPEG Noise Reduction level to High, Medium and Low.

Cross Color Suppressor: Remove cross color artifacts that can occur when high-frequency luminance (brightness) signals are misinterpreted as chroma (color) signals. This can cause unwanted flickering, flashing colors or rainbow patterns. Select "On" to turn ON this feature; otherwise, select "Off".

Film Mode Detect: While normally set to "Off", turn "On" this setting to compensate for authoring errors that may have occurred during the process of converting film programs to video.

LISTENING TO AM/FM RADIO

The T 747's internal AM/FM tuner offers very high quality sound from radio broadcasts. The reception and sound quality will always be dependent to a degree however on the type of antenna(s) used as well as proximity to the broadcast origin, geography and weather conditions.

ABOUT ANTENNAS

Connect the supplied lead-type FM antenna to the FM antenna input. Extend the lead. Experiment freely with your antenna placement and orientation until you get the clearest sound and lowest background noise. Fix the antenna in the desired position by using thumb tacks, push pins or any suitable means. In areas of poor FM reception, an exterior FM antenna can improve performance dramatically. If radio listening is important to you, consider consulting an antenna installation professional to optimize your system.

The AM loop antenna supplied with the T 747 (or a suitable replacement) is required for AM reception. Open the clip terminal lever; insert the wire making sure to match the color-coded (white and black) ends of the wire to that of the terminal and close the lever 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.

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.

IMPORTANT NOTICE

Unless otherwise specifically stated, navigating or accessing AM/FM functions can be undertaken by using either the AVR 3 remote control or the front panel buttons. If the control button or icon button being referred to is available on the AVR 3 remote control and front panel, then the reference to said button is applicable to both the AVR 3 remote control and front panel.

NOTE

When using the AVR 3 remote control to carry out AM/FM commands, ensure that the DEVICE SELECTOR is set to "TUN".

ASSEMBLING THE LOOP ANTENNA

1 Rotate the outer frame of the antenna.
2 Insert the bottom edge of the outer frame into the groove on the stand.
3 Extend the antenna cord.

SELECTING A TUNER BAND

Press the [AM/FM/DB] button on the AVR 3 while at AMP or TUNER device selector page. Each subsequent press of either button will toggle you through AM, FM and XM (or DAB) band. Stop (release button) at your desired tuner band.

TUNING AM/FM STATIONS

Upon selecting AM or FM band, use [TUNE / ] on the AVR 3 to perform slow manual search; press and hold to automatically search.

The front panel or AVR 3's [▶] buttons can also be used to tune for stations.

Press [▶] momentarily to step up or down between AM or FM frequencies.
2 Press and hold [▶] for more than 2 seconds to search up or down - the T 747's tuner will stop at the next sufficiently strong signal it encounters.
3 Pressing the [ / ] during the search process will stop the search.

DIRECT TUNING

If you know your desired station's frequency allocation, you can tune directly to the station.

1 Toggle [ENTER] button to switch between "Preset" and "Tune" mode (see the lower line of the VFD). Select "Tune" mode.
2 Using the numeric keys of the remote control, key-in the frequency allocation of the station. For example, to enter 104.50MHz, press "1", "0", "4", "5" and "0" or press "1", "0", "4" and "5".

SETTING RADIO PRESETS (AM/FM)

The T 747 can store up to 30 FM and 30 AM stations for immediate recall.

1 To store a radio preset, first tune the desired frequency (see above), then press AVR 3's [MEMORY] key.
2 The VFD will show the next available Preset number (If there are no more vacant Preset number, you can overwrite an existing Preset number by pressing the [ / ] buttons to select the Preset number you want to overwrite). Press the [MEMORY] button again to store the desired frequency on the Preset number shown (or use the [ / ] buttons to select another available Preset number and then, press [MEMORY] button again). Your desired frequency is now stored in the assigned preset.

Press [▲/▼] to step up or down between presets. Press and hold [▲/▼] to "scroll" continuously up or down. The AVR 3 remote's [PRESET▶/▶] keys work similarly.

AUTOMATIC PRESET

Preset stations may also be programmed automatically for the entire FM (or AM) band.

1 Toggle the [AM/FM/DB] button to select FM (or AM) band.
2 Press and hold the AVR 3's [MEMORY] button until the station frequency indication begins to increase.
3 Release the button and note that the tuner will search the entire FM (or AM) band, and stop briefly at each station that has acceptable signal strength. The T 747 will automatically assign a preset number to each station, and then search for the next station. Up to 30 of the best received FM stations (or 30 AM stations) will be automatically stored.

DELETEING A STORED PRESET

You can empty a preset by deleting the stored information.

1 Select the preset number to be deleted.
2 While at the selected preset number, press the AVR 3's [DELETE] button.
3 The preset will then be deleted and "DELETED" scrolls on the display.
4 To clear all the Presets at the same time, repeat step 2 again but this time do not release the [DELETE] button. Press and hold [DELETE] button until the current Preset number shown in the VFD is extinguished (P--). All Presets are now deleted.

CHOOSING THE TUNER MODE

The AVR 3's [TUNER MODE] key is a dual-purpose control. Toggle [TUNER MODE] toggle to switch between FM Stereo mode or FM Mono. In the normal position, "FM STEREO ON", only the stations with a strong signal can be listened to, and the noise between stations is muted.

Pressing the [TUNER MODE] button again ("FM STEREO OFF") allows distant and potentially noisy stations to be received. Noise is reduced 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.

ABOUTUSERNAMES

You can assign an eight character "UserID" to each radio preset, which will show in the front-panel readout whenever that preset is recalled.

ENTERING USER NAMES

To name a radio preset "NEWS", follow the procedure as below.

1 Recall the desired radio preset.
2 Then, press and hold [INFO] of the AVR 3 until the display shows a flashing cursor point.
3 Use the [ / ] buttons to select the first character of the name ("N" from the alphabetical list).
4 Press [▶] button to select the character and correspondingly move forward to the next position. (Press [▲] to go back to the previous character). Repeat this process for each character in sequence.
5 Press the [MEMORY] key again to store the User Name and exit the text-entry mode.

ABOUTRDS

The Radio Data System (RDS) permits sending small amounts of digital information using conventional FM radio broadcasts. The T 747 supports two RDS modes, station-name (PS mode) and radio-text (RT mode). 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, the readout's character section will show its station-name (PS) text: "ROCK101", for example.

Press the AVR 3's INFO key to toggle the readout between this and the station's radio-text (RT) readout, if any, which might scroll song- or artist-name, or any other text of the station's choosing.

Until now, analogue radio signals such as FM or AM have been subject to numerous kinds of interference on their way from the transmitter to your radio. These problems were caused by mountains, high-rise buildings and weather conditions. With Digital Audio Broadcast (DAB), you can now receive CD-like quality radio programs without any annoying interference and signal distortion. DAB broadcasts use digital signals rather than traditional analogue transmissions, thus providing clear high quality reception. You get far more robust reception and virtually hiss or crackle free sound with DAB as long as you are within a good coverage area.

With DAB, the listener can scroll through a list of available stations - then instantly tune to the station of his choice. There is no need either to remember channel frequencies. All broadcasts are selected by simply selecting the service name.

The T 747 makes it possible for you to enjoy listening to DAB broadcasts. The T 747 has a Digital Audio Broadcast (DAB) module socket on the rear panel for adding a separately sold and NAD-specified outboard DAB module – the NAD DAB Adaptor DB 1. All the control software for this format is included; just plug-in the module and start enjoying the CD-like quality sound and expansive content selection available with DAB.

IMPORTANT NOTICE

Unless otherwise specifically stated, navigating or accessing DAB functions can be undertaken by using either the AVR 3 remote control or the front panel buttons. If the control button or icon button being referred to is available on the AVR 3 remote control and front panel, then the reference to said button is applicable to both the AVR 3 remote control and front panel.

NOTES

• When using the AVR 3 remote control to carry out DAB commands, ensure that the DEVICE SELECTOR is set to "TUN".
• At DAB mode and with DEVICE SELECTOR set to "TUN", AVR 3's [TUNER MODE] button has the same function as that of front panel's [MENU] button.

CONNECTING THE DAB MODULE
