REMOTE CONTROL

(Figure 3.)

(Figure 4.)

Your NAD T 761 should be placed on a firm, level surface. Avoid placing the unit in direct sunlight or near sources of heat and damp.

Allow adequate ventilation. Do not place the unit on a soft surface like a carpet. Do not place it in an enclosed position such a bookcase or cabinet that may impede the air-flow through the ventilation slots.

Make sure the unit is switched off before making any connections.

The RCA sockets on your NAD T 761 are color coded for convenience. Red and white are Right and Left audio respectively, orange for digital input, yellow for Video Composite and NAD Link.

Use high quality leads and sockets for optimum performance and reliability. Audio RCA leads will function correctly for video signals, although it is recommended to use dedicated video leads where possible. For the digital inputs use dedicated leads for digital signal transfer. Ensure that leads and connectors are not damaged in any way and all connectors are firmly pushed home.

For best performance, use quality speaker leads of 16 gauge (1.5mm) thickness or more.

If the unit is not going to be used for some time, disconnect the plug from the AC socket.

Should water get into your NAD T 761, shut off the power to the unit and remove the plug from the AC socket. Have the unit inspected by a qualified service technician before attempting to use it again.

Do not remove the cover, there are no user-serviceable parts inside.

Use a dry soft cloth to clean the unit. If necessary, lightly dampen the cloth with soapy water. Do not use solutions containing benzol or other volatile agents.

REAR PANEL CONNECTIONS (Figure 1.)

1. FM & AM ANTENNA

AM ANTENNA

An AM loop antenna is supplied with the T 761 and is required for AM reception. Open the clip terminal lever and insert the wire from the antenna. Closing the lever will lock the wire in place (Fig. 5). Test various positions for the antenna, but always ensure the loop is placed vertically for best reception. Placing the antenna close to large metal items such as metal shelves or radiators may interfere with reception.

NOTE:

When reception is not satisfactory using the supplied AM loop antenna alone, connection of an external antenna is recommended. Do not connect anything other than a loop antenna to the AM ANTENNA terminal. Do not remove the AM loop antenna. The antenna cable to the loop antenna must not exceed 3 meters.

FM ANTENNA

A ribbon wire FM antenna is included and should be connected to the FM connector at the rear of the unit (Fig. 4) using the 'balun' adapter supplied. The ribbon aerial should be mounted on a vertical surface and placed so that it forms a 'T'.

Experiment with placement of the antenna to find the position that gives the best signal strength and lowest background noise. An inadequate FM signal normally results in high levels of hiss, especially in stereo, and interference from external electrical sources. In areas of poor FM reception, the tuner section's performance can be improved by using an externally mounted FM antenna. A qualified aerial installer will be able to advise and fit a recommended aerial for your reception conditions.

2. TAPE 1 & CD INPUT

TAPE 1

Connections for analogue recording and playback to an audio tape recorder of any type, such as a cassette, reel-reel, DAT, MD or DCC. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Output' of the tape machine to the TAPE 1 IN connectors for playback. Connect the left and right 'Audio Input' of the tape machine to the TAPE 1 OUT connectors for recording.

CD INPUT

Apart from the audio signal, these inputs will also accept a video signal which will be routed to the Monitor Out sockets (No. 8) for a television or video projector. The Video inputs also have the option of a Video Composite connection (using the yellow RCA socket) or an S-Video connection (using the Mini-Din connector).

The S-Video standard allows for higher quality video signal transfer when compared to the Video Composite standard. If your video components have an S-Video connector use dedicated S-Video leads to connect them to the T 761 in the same way as described with the Video composite equivalents.

A video signal fed to an S-Video input socket will be available on both the S-Video Monitor Out and Video composite Monitor Out.

Inputs for the audio playback and video signal from a video device such as a stereo TV, DVD player, satellite cable TV receiver or a Laser Disc. Using twin RCA-to-RCA leads, connect to the left and right 'Audio Out' of the video device to these inputs. Using a single RCA-to-RCA lead (Video Composite) or S-Video lead, also connect the video output of the video device; refer also to the description of S-Video and Video Composite in section No. 5 of this chapter. VIDEO 1 &VIDEO 2 can be used for video playback only. Use VIDEO 3 orVIDEO 4 if you want to connect a VCR for recording and playback through the T 761.

Using twin RCA-to-RCA leads, connect to the left and right 'Audio Out' of the VCR to the VIDEO 3 or VIDEO 4 IN connectors for playback. Connect the left and right 'Audio In' of the VCR to theVIDEO 3 orVIDEO 4 OUT connectors for recording. Using a single RCA-to-RCA (Video Composite) lead or S-Video lead, also connect the video output of the VCR to Video In for Video playback. Connect the Video Input of the VCR to Video Out of the NAD T 761 receiver for recording of video signals. Refer also to the description of S-Video and Video Composite above in this section.

The coaxial Digital Input 3 (No. 6) is linked to the Video 3 input. Select Video 3 to hear a source connected to Digital Input 3.

The coaxial Digital Input 4 (No. 6) is linked to the Video 4 input. Select Video 4 to hear a source connected to Digital Input 4.

5. 5.1 CHANNEL INPUTS

Inputs for the multi-channel audio signals from an external decoder, such as an MPEG decoder or a DVD player with integrated decoder. Use two twin RCA-to-RCA lead to connect the decoder's front left and right "Audio Outputs" to the Front left and right inputs, and the decoder's Surround left and right outputs to the Surround left and right inputs. Use a third

twin RCA-to-RCA lead to connect the decoder's subwoofer output to the Subwoofer input and the decoder's Center channel output to the Center channel input. Make sure you to follow color coding of the plugs to ensure that both Center and Subwoofer are connected correctly, for instance, use the red plugs at either end to connect the center channel and the white plugs for the subwoofer channel.

6. DIGITAL AUDIO INPUTS & DIGITAL AUDIO OUTPUT

The T 761 has five digital audio inputs to allow for connection of DVD, CD, Laserdisc, Satellite receiver or other digital sources:

Digital Audio Input 1 and 2 allows for connection of a digital source with an Optical output. Use a cable terminated with a TOS Link connector. Digital input 1 is linked to the Video 1 input; Digital input 2 is linked to Video 2.

Digital Audio Inputs 3,4 & 5 allow for connection of a digital source with a Coaxial digital output. Use a cable with the right impedance, specifically designed for the transfer of digital signals. These digital inputs are linked respectively to VIDEO INPUT 3,VIDEO INPUT 4 and CD input.

The T 761's coaxial digital output allows for connection to a digital recording device, such as a CD or MD recorder. The digital output passes through the digital signal from the selected digital input, either coaxial or optical.

NOTE:

Most digital recorders accept only very specific types of digital signal. It is likely it's impossible to record the digital signal from a DTS or Dolby Digital encoded disc.

7. AUDIO PRE-OUTS / SUBWOOFER OUT AUDIO PRE-OUTS

The NAD T 761 receiver has five power amplifiers built-in to power all the speakers connected to it (Left, Right, Center, Left Surround, Right Surround). It is also possible to use the T 761 as a pre-amplifier to drive external power amplifiers. This way, you use all the control functions the T 761 provides, such as input select, surround mode, volume, tone controls, etc., but the external power amplifier actually powers the speaker connected to it instead of the T 761's integrated power amplifier for that channel.

Connect the RCA-to-RCA leads from the Front left and Right, Center, and/or Surround Left and Right Audio pre-out connectors to the external amplifiers. Connect speakers to the external amplifiers.

NOTES:

Never connect the T 761's speaker outputs and the speaker outputs of an external amplifier to the same speakers. When headphones are inserted the signals from all audio pre-out outputs will be muted.

Before making any connections, check that the T 761 and the power amplifiers it will be connected to are switched off. With volume turned down to a low level, switch power on only after all connections have been made.

SUBWOOFER OUT

Unlike for the full range five channels as described above, there is no power amplifier built-in for an additional subwoofer. The Subwoofer pre-out allows for connection to a sub-bass speaker system with its own external or integrated power amplifier ("active" subwoofoers).

8. COMPONENT VIDEO IN & COMPONENTVIDEO OUT

The Component Video Input is linked to Video 1. Selecting Video 1 will route a component video signal connected to the Component Video In sockets to the Component Video Out sockets.

Using dedicated high-quality video leads, connect the output from a Component Video device, such as a DVD player to this input. Connect the Component Video output to the projector or monitor.

NOTE:

With Component Video, the video signal is separated into three different signals. This approach potentially offers the best video playback possible. Component Video Y/C/B is also known as Y/Pb/Pr, Y/Cb/Cr or Y/R-Y/B-Y.

Make sure that the component output type of the video source is compatible with the monitor or projector and that all connections are correct, with no cross-wiring.

9. MONITOR OUT

Composite Video and S-Video outputs for connecting a TV or Video Monitor to view video sources connected to VIDEO 1 toVIDEO 5. Using a Video RCA-to-RCA lead, connect the "Video Line In" on the TV or monitor to the MONITOR OUT.

Note that an S-Video signal will also be available as a Video Composite signal on Monitor out, if the corresponding source is selected. The composite video input signals (No. 5; yellow sockets) will also be avail-able as S-Video signal on the Monitor Out socket. If you use both S-Video and Video composite sources, you will only need to connect the S-Video Monitor Out to the television or projector.

Connect the right speaker to the terminals marked 'FR' ensuring that the red terminal is connected to the ^+ terminal on your loudspeaker and the black termi

nal is connected to the loudspeaker's '-' terminal. Connect the terminals marked "FL" to the left speaker in the same way.

Always use heavy duty (16 gauge; 1.5mm or thicker) stranded wire to connect loudspeakers to your T 761.

Unscrew the speaker terminal's plastic bushing. Insert the bare cable end into the hole of the terminal and then secure the cable by tightening down the terminal's bushing (Fig. 6).

To avoid any danger of bare metal from the speaker cables touching the back panel or another connector, ensure that there is only 1/2 (1.27cm) of bare cable and no loose strands of speaker wire.

NOTE:

This unit is designed to produce optimum sound quality when speakers with impedance within the set's ranges are connected. Please check the following information and choose speakers with the correct impedance for the connections.

FRONT SPEAKERS A: 4 ohms min. per speaker;

with Speakers B

connected also,

min. 8 ohms.

CENTER SPEAKER B: 4 ohms min.

SURROUND SPEAKERS: 4 ohms min. per speaker

CENTER SPEAKER

The terminal marked 'C' connects to the center loudspeaker that is used when the T 761 is operated in Dolby Digital, DTS, Dolby Pro Logic, EARS surround sound mode or with the 5.1 Ch. input selected.

Connect the center speaker in the same way as described with FRONT SPEAKERS above.

SURROUND SPEAKERS

This connects the Surround loudspeakers that are used when the T 761 is operated in Dolby Digital, DTS, Dolby Pro Logic, EARS Surround sound modes or with the 5.1 Ch. input selected.

Connect the surround speakers in the same way as described with FRONT SPEAKERS above; connect the left surround speaker to the set of terminals marked 'SL' and the right surround speaker to the terminals marked 'SR'.

NOTE:

The Center and/or Surround speakers must be selected as Large or Small in the Set-up menu "SPEAKER SELECTION" when speakers are connected to these outputs. Refer also to chapter "On Screen Display (OSD)" for more information.

11. SPEAKERS B

Connect the right speaker to the terminals marked 'R' ensuring that the red terminal is connected to the +^ terminal on your loudspeaker and the black terminal is connected to the loudspeaker's - terminal. Connect the terminals marked L' to the left speaker in the same way.

NOTE:

The minimum impedance for both Speakers A and Speakers B must not be below 8 ohms if both Speakers A and Speakers B are connected.

12. SOFT CLIPPING

When any amplifier is driven beyond its power output capabilities, a hard, distorted sound can be heard on very loud sounds. This is caused by the amplifier cutting off or 'hard clipping' the peaks of sound that it was not designed to reproduce. The NAD Soft Clipping circuit gently limits the output of the system to minimize audible distortion if the amplifier is overdriven.

If your listening involves moderate power levels you may leave the Soft Clipping switch off. If you are likely to play at high levels that exceed the amplifier's power capability, then switch Soft Clipping on.

13. NAD-LINK IN OUT

The NAD-Link connector is used to pass commands from other units fitted with NAD-Link connectors. This allows centralized control of a complete system, and also allows some of the basic functions of other NAD components (such as a CD player) also equipped with NAD-Link to be controlled with the receiver's remote control. To function with such other units, connect the T 761's NAD-Link Out to the NAD-Link In on the other unit. NAD-Link connectors can be daisy-chained, IN to OUT, so that a whole system can be controlled from the remote control facilities of one unit.

NOTES:

It is advisable not to connect NAD-Link if these units that have their own built-in remote control command receiver and are positioned together, in direct view from the remote control handset. If you are unsure, try operating the products without NAD-Link first; If the unit responds to the remote control command, it will not be necessary to connect NAD-Link.

Never loop the last unit back to the first NAD unit in the NAD-Link chain.

Unplug all units from the mains before connecting or disconnecting NAD-Link.

14. 12V TRIGGER IN OUT

The 12V Trigger input allows the T 761 to be

switched remotely to stand-by and and vice-versa by ancillary equipment such as a preamp, AV processor, etc. which are equipped with a 12V trigger output.

The 12V Trigger output allows to remotely switch on or off ancillary equipment such as a tuner, power amplifier, etc. which are also equipped with a 12V trigger input. This can also be an AC outlet power strip equipped with a 12V trigger input. The 12V trigger output is activated whenever the T 761 is switched to normal operational mode from Stand-by or Off.

For switching Stand-by/Power On of the T 761 or an external component, connect the 12V-trigger in/output of the T 761 to the remote component's DC out/Input jack. The plug required is a standard 3.5mm Mini-Jack plug ("mono"): The tip is the live or + connection, the shaft of the input jack is the 12V-trigger -or ground connection.

NOTES:

Check the specifications of the Trigger input and output terminals on the other components to ensure these are compatible with respectively the T 761's 12V-trigger output and input.

The T 761's 12V Trigger input will work within a range of 6 to 15V DC level and typically draws less than 10mA of current.

The T 761's 12V-trigger output voltage is 12V DC. The total maximum current must not exceed 200mA . Typically, NAD 12V input triggers draw less than 10mA of current.

NAD components equipped with 12V input or output triggers are fully compatible with the T 761's 12V output and input trigger.

Before making any connections to any 12V trigger input or output, make sure all components are disconnected from the AC mains.

Failure to observe the above may result in damage to the C-530 or any ancillary components attached to it. If in doubt over the connections, installation and operation of the 12V trigger output consult your NAD dealer.

15. SWITCHED POWER OUTLETS

The AC power cords of other stereo components, such as a CD player, may be plugged into these accessory outlets.

Components plugged into the outlets will be switched on and off as the T 761 is switched from stand-by or off to on and vice versa.

NOTE:

The total power consumption of any components connected to the AC outlets may not exceed 120 Watts. Never connect the mains lead of a power amplifier to the switched power outlets of the NAD T 761.

NOTE:

The AC outlets should be used with units with a COMBINED power consumption of no more than 120 Watts.

16. AC POWER CORD

After you have completed all connections to the amplifier, plug the AC line cord into a "live" wall socket.

17. COOLING FAN

The cooling fan allows T 761 to deliver high amounts of power without the unit becoming too hot. The fan will only operate when the temperature of the internal components starts to become hot.

NOTE:

Ensure that the air outlets of the fan aren't blocked in any way.

FRONT PANEL CONTROLS (Figure 2.)

1. POWER

Press the POWER button to switch the receiver to normal operation mode. The display will light up indicating which input was selected; the Stand-by indicator will extinguish.

Pressing the POWER switch again will turn the unit OFF completely. The NAD T 761 receiver uses a memory back-up system to store surround sound trim settings and Preset station information for the tuner section. This information is retained for several weeks, even the unit is switched off completely or unplugged.

REMOTE CONTROL:

STAND-BY button (green):

Press this button to switch the unit from operating to the Stand-by mode and vice versa. Press this button again to switch to unit on from Stand-by; the last selected source will be indicated in the display.

NOTE:

Stand-by mode is indicated by the Stand-by indicator (No. 2) just over the green POWER button on the front panel (No. 1).

In Stand-by mode the T 761 uses very little power. However, it is recommended that you switch the unit totally off if it is not going to be used for more than a couple of days. Switch off completely by pressing the POWER button on the front panel (No. 1), all lights will extinguish.

2. STAND-BY

This green LED will light up when the receiver is switched On, but in Stand-by mode. Refer to section 1 in this chapter for more information.

3. DISPLAY

The T 761's FM tuner supports RDS PS and RDS RT. With stations carrying RDS information, "RDS" will light up in the display panel, and the station is RDS name is automatically displayed (RDS PS).

Some radio stations, which support RDS, also transmit additional information, known as Radio Text (RDS RT). To view this information, use the DISPLAY button.

With stations carrying RDS information, the DISPLAY button scrolls between three different display modes, each successive push of the button engages the next one of the three modes:

a) In the default mode, the station's RDS name is displayed, Program Service (PS; normally the station's calling letters, BBC R3, for instance).
b) From the default mode, press the button once to view Radio Text (RT). This can be additional information such as the presenter's or program's name; what song is playing, etc. This text scrolls continuously over the 8 alphanumeric display segments. It takes a few seconds for the tuner to gather the RT information, so immediately after tuning to a station and selecting to view RT the display will indicate "NO TEXT" and default to the station name. If no RT information is available, the display will also show "NO TEXT" for three seconds before reverting to the default mode.
c) Press the button from the display RT mode to display the station frequency. Press again to return to the default mode (a).
When the DISPLAY button is pressed when tuned to a non-RDS station the display will show "NO NAME" for three seconds before reverting to the default display:

The DISPLAY button toggles the display to show either the station frequency or user entered station name. If no user name was entered the display will just flash once.

4. AM/FM

The AM/FM button switches the tuner section from the AM band to the FM band and vice-versa. The Display Panel shows the frequency of the tuned station and which band is selected. The FM tuning is in 0.05 MHz increments, AM tuning is in 9 kHz or 10kHz increments, depending on the version (9 kHz for the 230V version or 10 kHz for the 120V version).

To change the AM increment tuning steps, press the FM Mute (No. 5) and Digital Audio Selector (No. 15) at the same time. After switching the unit on and off once, the AM tuning steps will be changed.

5. FM MUTE / MODE

This button combines two functions; it switches the tuner from Stereo to Mode and disengages the muting circuitry at the same time. The muting circuit will mute the tuner in between radio stations when searching or tuning. This way the tuning noise is avoided.

Very weak radio station signals however may be suppressed by the muting circuit. if such a very weak station is in stereo it will have a high level of background hiss. Switching to Mode and disengaging the muting circuit by depressing the FM MUTE/MODE button will allow the station to be heard and will cancel most or all of this background noise.

In normal operation the mute circuit is engaged, the display indicates "FM MUTE". Press the FM MUTE/MODE button to disengage the muting circuit and switch from stereo to mono reception. "FM MUTE" will extinguish in the display. Also, "STEREO" will extinguish if a stereo broadcast was received. Press the FM MUTE/MODE switch again to return to Auto Stereo FM operation.

In combination with the MEMORY button (No. 6) a preset number can be emptied. (Refer to the separate chapter "Storing and Recalling Presets" for more information.)

6. MEMORY

The MEMORY button is used to store stations into the Preset Memory (1-30 Presets on FM, 1-10 Presets on AM), used in conjunction with the DOWN/UP (No. 8) buttons on the front panel. In combination with the FM MUTE/MODE button (No. 5) a preset number can be emptied. When Memory is active, the Preset number flashes and the red "MEMORY" indicator is shown in the Display Panel. If no other button is pressed within 10 seconds "MEMORY" will stop flashing and the receiver will default to its previous state.

Refer to the separate chapter "Storing and recalling Presets" for more information.

7. PRESET/TUNE

The PRESET/TUNE button toggles between the Preset and Tune mode. When Preset mode is selected, "PRESET" lights up in the display area.

Up to 40 Presets, either AM (10 Presets) or FM (30 Presets), can be stored.

Refer also to separate chapter "Storing and Recalling Presets" for more information.

8. DOWN / UP and

The function of these buttons depends on the tuning mode selected with the PRESET/TUNE button (No. 6). The PRESET/TUNE button toggles between the two operation modes:

a) Preset mode (indicated in the display area): Press the “ ” (down) button to scroll to a lower number Preset; press the “ ” (up) button to scroll to a higher Preset number. This is a “wrap-around” function, so that going from the highest number Preset, the tuner will go to the lowest Preset number or vice-versa when tuning either up or down.
b) Tune mode: Press the “ ” (down) or “ ” (up) button for more than 1/2 second to engage automatic tuning respectively up or down the frequency band. The tuner will search automatically for the first reasonably strong radio station, where it will stop. Press the Down/Up button again for 1/2 second to start searching again.

NOTE:

Automatic tuning is available on both FM and AM.

By briefly tapping the “ ” (down) or “ ” (up) buttons you can engage manual tuning respectively down or up the frequency band for precise tuning to a specific frequency. With each successive tap of the keys, the tuner will take 0.1 MHz steps (120V version) or 0.05 MHz steps (230V version) on FM so you can accurately tune into the desired frequency.

This tuning mode can also be useful when trying to receive a radio station which is too weak for the auto search mode. When tuned accurately to a station, “▶TUNED ” will light up in the display. Very weak radio station signals however may be suppressed by the muting circuit. If such a very weak station is in stereo it will have a high level of background hiss. Switching to Mode and disengaging the muting circuit by depressing the FM MUTE/MODE button (No. 5) will allow the station to be heard and will cancel most or all of this background noise.

Refer to the separate chapter "Storing and Recalling Presets" for more information.

9. VFL DISPLAY

Vacuum Fluorescent Display. The display area will show all vital information when the unit is operational.

10. VOLUME & SET UP

In the default function, this control acts as a Volume control, adjusting the overall loudness of the signals being fed to the loudspeakers. Unlike conventional controls, the T 761's volume control doesn't have a start of end position. Volume can also be adjusted from the remote control handset using the MASTER VOLUME Up or Down buttons. The Volume control does not affect recordings made using the Tape, Video 3 and Video 4 outputs but will

affect the signal going to the Pre-amp output (Audio Pre Out). The volume level is indicated in the display panel when it is being adjusted. After three seconds the display defaults to its previous status. Volume setting can range from -∞ to +18dB ....

On the remote control handset, press the MUTE button to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by "MUTING" flashing in red in the display area. Press MUTE again to restore sound. Mute does not affect recordings made using the Tape, Video 3 and Video 4 outputs but will affect the signal going to the Pre-amp output (Audio Pre Out).

The control is also used to adjust various set-up settings and levels for the T 761. In conjunction with the Levels button (No. 18) the relative volume levels of all speakers can be adjusted; in conjunction with the Tone Control button (No. 19) the Bass and Treble levels can be adjusted. Refer also to sections "Level" and "Tone controls" in this chapter.

The Surround Mode buttons scroll through the available surround sound modes:

With any of the Digital Inputs 1, 2, 3, 4 or 5 selected, the T 761 automatically recognizes if the selected source carries a Dolby Digital ^TM or DTS ^TM signal. When no Dolby Digital or DTS signal is available, the Surround Mode buttons scroll through the other available surround sound modes:

Stereo Pro Logic Ears Stereo, etc.

With either Dolby Digital or DTS surround mode engaged, the Dolby Pro Logic and Ears surround modes cannot be selected. Dolby Digital and DTS has six independent channels available in total: Left, Center, Right, Surround left, Surround Right and an "Effects Channel" (Subwoofer).

The Dolby Digital signal allows for several channel configurations.

DTS digital surround is an Encode/Decode system that currently delivers six discrete channels (5.1) of "Master-Quality" up to 24-bit audio.

Dolby Pro Logic decodes the center and surround sound signals embedded in stereo movie sound tracks from e.g. video, Laser Disc or TV. To decode correctly, the source must be a Dolby Surround or Dolby Stereo soundtrack.

In the EARS (Enhanced Ambiance Retrieval System) Surround Mode, a realistic level of ambience of surround sound is added to a normal stereo source such as a CD or FM radio.

NOTES:

Dolby Digital or DTS are only available as a Surround Mode if the source is either Dolby Digital or DTS and a Digital Audio input is used.

An external source such as a decoder or DVD player with a decoder built-in (MPEG for instance) can be connected to the Ext. 5.1 input (No. 16 on the front panel). When the EXT 5.1 CH. input is selected, no other surround modes are available.

To obtain the best performance possible it is important that the system and all speakers have been set up correctly. Refer to the chapters "On Screen Display" and "Setting Up the Surround System".

18.LEVELS

With the Levels button adjustments can be made to the relative loudness of all speakers. With each successive press (within the 5 second default time) the display scrolls through the available channels/speakers:

Using the Volume (Set up) control (No.10) the relative level for the selected speaker/channel can be adjusted by +10 or -10dB .

On the remote control, use the Curser Left and Right buttons to respectively de-or increase relative level for selected speaker.

NOTES:

When using Level Adjustment, the "Channel Balance" On-Screen-Display menu is activated. Adjustments to the settings are retained in memory for all surround sound modes.

Only those speakers can be adjusted that have been selected in the Speaker Settings Menu. For more information refer also to the chapters "On Screen Display (OSD) and "Setting up the Surround System".

19. TONE CONTROLS & TONE DEFEAT

The T 761 is fitted with BASS and TREBLE tone controls to adjust the overall tonality of your system. These can be adjusted only with Tone Defeat set to ON.

The Tone Defeat button activates or de-activates the tone controls. Press once to activate the tone controls, the display area will indicate "TONE ON". Press again to de-activate the tone controls, the display area will indicate "TONE OFF". In the Tone Off

position, the tone control is "flat", no bass or cut for Bass or Treble.

To adjust Bass and Treble, activate the tone controls as indicated above and press the Tone Controls button. Upon the first press, the Bass can be adjusted, the display area indicates "BASS" and the relative bass level. Within the default time (5 seconds) press again to adjust Treble.

Using the Volume (Set up) control (No.10) the relative level for Bass and Treble can be adjusted by +10 or -10dB in 2dB steps.

These controls affect the Left and Right Front speakers. The Tone controls do not affect recordings made using the Tape or Video line outputs but will affect the signal going to the Pre-amp outputs (Audio Pre Out).

STORING AND RECALLING PRESETS

To store a Preset:

• Tune to the radio station you wish to enter into a Preset (refer to chapter "Front Panel Controls"; sections 7 and 8). If the station is transmitting RDS information, the RDS indicator will light up and station initials will be shown in the Display Panel. If a non-RDS station is found, then just the frequency will be shown.
• To store that station as a Preset, press MEMORY (No. 6). "MEMORY" and the preset section in the display panel will start to flash. If no other button is pressed within 10 seconds, "MEMORY" will stop to flash and the receiver will default to its previous state.
• Press either the “ ” (down) or “ ” (up) button (No.8) to select which Preset number you wish to assign to the station (from 1 to 30 on FM and 1 to 10 on AM), shown as a flashing number in the Display Panel, and then press MEMORY (No. 6) again. The Memory light in the Display Panel will go out and the station is now stored in your NAD T 761's memory.

To exit the Memory mode without storing a station, leave all the tuner controls untouched; the Memory mode will automatically cancel itself after 10 seconds. The Memory Presets have a memory back-up, so they will remain stored for several weeks even if the Receiver is switched off or unplugged from the mains supply.

NOTE:

You can enter a new station into an unused Preset or over-write an existing programmed Memory Preset. By doing this you will replace the radio station previously held on that Preset number.

Recalling a Preset station:

• To select a Preset station, select the Preset mode by pressing the PRESET/TUNE button (No. 7) until

"PRESET" lights up in the display.

• Press either the “ ” (down) or “ ” (up) button (No. 8) until the right Preset is found and shown in the Display Panel.

NOTE:

Any unused Presets will be skipped.

Deleting a stored Preset:

You can empty a Preset by deleting the stored information:

• Select the Preset to be emptied.
• Press the MEMORY button (No. 6), followed by the FM MUTE/MONO button (No. 5). The Preset will then be deleted and '--' appears as the Preset number.

You can also store a new station into a used Preset, by simply going through the Preset storing process and placing a new station over the existing one.

REMOTE CONTROL

Apart from all the key functions, the T 761's Remote Control handset also gives access to functions not available on the front panel. It also has additional controls to remotely operate NAD Cassette and CD machines. It will operate up to a distance of 16ft (5m).

Alkaline batteries are recommended for maximum operating life. Two AAA (R 03) (depending on version) batteries should be fitted in the battery compartment at the rear of the Remote Control handset. When replacing batteries, check that they have been put in the right way round, as indicated on the base of the battery compartment.

There are a few differences and extra functions with the remote control handset however:

Pressing the SLEEP button once will set the sleep time to 90 minutes, after which the T 761 will automatically switch off into Standby mode. Sleep mode is shown on the Display Panel. To adjust the Sleep Delay, press the SLEEP button, each consecutive press will reduce the sleep time in 30-minute increments, as shown in the Display Panel. To cancel the Sleep mode, continue pressing the SLEEP button until the

sleep time returns to 0 minutes. Pressing the POWER on the front panel (No.1) or STAND-BY button will also cancel the Sleep mode.

MUTE:

Press the MUTE button to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by "MUTING" flashing in red in the display area. Press MUTE again to restore sound. Mute does not affect recordings made using the Tape outputs but will affect the signal going to the Audio Preouts.

NOTE:

When the unit is in mute mode, any adjustment of the VOLUME CONTROL on the front panel (No.9) will release the muting, i.e. the original volume level will be resumed.

VIDEO 1,2,3,4,5, CD, DISC, EXT.5.1, FM, AM

Unlike the T 761 front panel operation, where sources are selected indirectly using the Input Down/Up buttons, these inputs can be accessed directly by pressing the button for the desired source.

- MASTER VOLUME

Master Volume or respectively increases or decreases the volume setting for all speakers. The display panel will indicate the level set. The Volume control does not affect recordings made using the Tape and Video, or Tape, Video 3 and Video 4 outputs but will affect the signal going to the Pre-amp output (Audio Pre Out).

CURSOR▲,▼,▲AND▲AND ENTER

The four Cursor buttons are used to navigate the cursor when using the menus with the On Screen Display and the ENTER is used to confirm the choice. Press to move cursor up, to move cursor down, to move cursor left, to move cursor right. Then press ENTER to access.

With the four cursor buttons the relative volume level trims for center, left and right surround channels can be adjusted. Press the LEVELS button to select the channel for which you wish to adjust the level.

Refer also to chapter "On Screen Display" and "Setting Up the Surround Sound System" for more information.

TEST

Pressing the TEST button, engages the Test signal generator to allow for adjustment of all speaker levels, so that each channel can be adjusted for equal loudness at your listening position. The test signal scrolls automatically with 5-second intervals from Front Left, Center, Front Right, Rear Right, Rear Left, to subwoofer in continuous cycles. If an adjustment in setting is made for one of the speakers, scrolling will stop until 5 seconds after the adjustment was made.

Both display panel and OSD show which speaker is being fed with the test signal. Use the cursor and button to respectively decrease or increase the level for the current speaker. Press the TEST button again to leave or cancel the Test mode, any changes will be memorized automatically.

Refer also to chapter "On Screen Display" and "Setting Up the Surround Sound System" for more information.

- LEVELS

Although the T 761 is correctly set-up it may sometimes be desirable to make minor adjustments to suit particular software. Pressing the LEVELS button allows for direct adjustment of Center, Rear and Subwoofer levels. Press the LEVELS button to scroll to the next speaker. Both display panel and OSD show which speaker can be adjusted. Use the cursor and button to respectively decrease or increase the level for the current speaker.

With each successive press within the default time the unit scrolls to the next available channel for adjustment:

LEFT CENTER RIGHT REAR RIGHT REAR LEFT SUB OFF

Refer also to the chapter "Setting Up the Surround Sound System" for more information.

DYNAMIC RANGE

The DYN. R button, which can be used only in combination with a Dolby Digital source, incrementally reduces the audio track's dynamic range in four steps (100%, 75%, 50% and 25%) to allow for comfortable listening under a variety of conditions. The normal or default position is 100%.

To adjust the dynamic range, each consecutive press of the DYN. R button will reduce the value in 25% increments, as shown in the alpha-numeric display section.

NOTE:

Although we usually prefer to reproduce a source's full dynamic range (the difference between very loud and very soft sounds), it may occasionally be desirable to reduce the dynamic range. For example, when playing a movie late at night, loud explosions might wake sleeping family members. Simply turning the volume control down would probably make a whisper in the next scene inaudible. The DYN.R button solves this dilemma by progressively lowering the volume of loud peaks while increasing the level of softer sounds.

- MODE

The MODE button scrolls through the available surround sound modes. The button functions in the same way as the SURROUND MODE button on the T 761 front panel (No. 11 on front panel drawing).

The selected Surround mode is permanently indicated in the display area and is also shown for 3 seconds in the alpha-numeric display section.

- CD PLAYER CONTROL (for use with NAD CD Players).

NOTES:

Direct sunlight or very bright ambient lighting may affect the operating range and angle for the remote control handset.

The infrared remote control command receiver, located on the far left of the display window, receives commands from the remote control. There must be a clear line-of-sight path from the remote control to this window; if that path is obstructed, the remote control may not work.

ON SCREEN DISPLAY (OSD)

The NAD T 761 is equipped with an elaborate On Screen Display facility (OSD). As the OSD is an essential tool to set up the various parameters for Surround sound correctly it is recommended that you connect your monitor or television to the T 761.

Depending on your source and/or the television system used you must first select the correct video system. If the OSD rolls over the screen you must select another system: PAL or NTSC.

• While pressing the MEMORY button (No. 6) on the front panel, press the SPEAKERS A button (No. 12) repeatedly until the desired system is shown in the display area and OSD.

The OSD can be engaged by pressing one of the four cursor buttons on the remote control. The SETUP Menu will appear as below:

4. SPEAKER SETTINGS

The size and number of speakers can be described in the SPEAKER SETTINGS menu. Highlight SPEAKER SETTINGS in the SETUP menu and press ENTER on the remote. You will see a screen similar to the following:

SPEAKER SETTINGS

MAIN : LARGE/SMALL

CENTER : LARGE/SMALL/OFF

The description LARGE and SMALL mean the following:

The LARGE mode is used when the speaker is full range and capable of reproducing the entire audible frequency spectrum 20Hz to 20kHz.

The SMALL mode is used when the speaker is not capable of reproducing the deepest bass portion of the audio frequency 20Hz to 100Hz.

You are given the following choices:

MAIN

For the left and Right speakers, you can select Large or Small. When Small is selected, the deepest bass portion is re-directed to the subwoofer.

- CENTER

You can choose Large, Small or Off. When Small is selected, the deepest bass portion is re-directed to the subwoofer. With Off selected, all information for the Center channel will be equally divided over the Left and Right speakers.

- SURROUND

You can choose Large, Small or Off. When Small is selected, the deepest bass portion is re-directed to the subwoofer. With Off selected, all information for the Surround channels will be equally divided over the Left and Right speakers.

- SUBWOOFER

You can choose ON and OFF. With Subwoofer set to ON, the LFE (Low Frequency Effects) channel

and the deepest bass for all other channels will be routed to the Subwoofer. With OFF selected, the LFE channel and deepest bass will be equally divided to all those speakers which have been set to Large.

NOTES:

Speakers set to "Large", will in addition reproduce the deepest bass, when Subwoofer is set to ON.

It's advisable to select Large for the Main speakers when subwoofer is set to OFF.

To obtain the best results in any of the Surround Modes it is important that the T 761 is carefully set up. Performing the complete setup is done using the On Screen Display menus. It is therefore recommended you connect your Television or monitor to the T 761 monitor output.

Refer to the chapter "On Screen Display (OSD)" on how to access the SETUP Menu of the On Screen Display, choose sub-menus and change settings.

The setup procedure is broken down in three sections:

1. Speaker Settings
2. Channel Balance
3. Channel Delays

Speaker Settings:

First you need to indicate which speakers are connected to your T 761. Besides the Main speakers (Left & Right), these can include a Center, two Surround Speakers and a Subwoofer.

• Call up the SETUP menu of the On Screen Display (Fig. 7)
• Select the SPEAKER SETTINGS (Fig. 11)
• Highlight PRESET and use or cursor button to select the preset (PRESET 1, 2 or 3) that best applies to current setting or change the speaker fields individually as desired.

Four modes available appropriate to the T 761's setup: LARGE or SMALL and ON or OFF.

The LARGE mode is used when the speaker is full range and capable of reproducing the entire audible frequency spectrum 20Hz to 20kHz . The SMALL mode is used when the speaker is not capable of reproducing the deepest bass portion of the audio frequency 20Hz to 100Hz .

The ON mode is used when the speaker is active and receives the audio information intended. The OFF mode is used when the speaker is inactive. Audio signals intended for speakers set to the OFF position are redirected to the main speakers.

Using a separate center channel speaker will allow the dialogue to cut through even the biggest sound effects and musical scores. Having the sound spread across three front speakers also stabilizes the stereo

image, making the usable listening area much bigger.

For best results, you should consider using a center speaker. Ideally it should be the same type as the left and right speakers.

• Choose SURROUND and select one of the three modes available: Small, Large, Off.

Installing surround speakers will greatly enhance the surround experience as these add considerably to the overall "ambience".

Dolby Pro Logic encoded material is deliberately limited in dynamic range and frequency bandwidth for the surround channel and thus only requires speakers of far lesser specification compared to the front channels. Dolby Digital however is a full range system, with two independent surround channels and with dynamics equal to that of the front channels. For this reason it is advisable to choose loudspeakers which are similar in power handling and performance capability to those of the front channels.

For best results, the Surround loudspeakers should not beam the sound directly at the listener. One way of achieving this is to use 'dipole' Surround speakers which aim the sound down the walls rather than directly into the room.

Many film soundtracks rely heavily on very low frequency sound effects which are difficult for normal or smaller hi-fi speakers to reproduce. To faithfully reproduce these low frequencies you can use a specially designed low frequency loudspeaker with its own built-in amplifier ("active subwoofer"). Because it is difficult to hear which direction very low frequencies are coming from, you only normally need one subwoofer and this can be placed virtually anywhere in the room. The Subwoofer output of the T 761 is designed specifically to drive a subwoofer system.

Dolby Digital uses a dedicated Low Frequency Effects (LFE) channel. If a subwoofer has been selected, the LFE channel will be fed to the subwoofer output.

Channel Delays:

For the best surround sound performance it is important that sound from all speakers reach the listener's ears at the same time. Because the surround/rear speakers are usually closer to the listener than the front speakers, there is tendency for the ear to localise sounds to the rear, because the ear takes most notice of the sounds that arrive at the head first. Similarly, the center speaker is often closer to the listener than the front left and right speakers. To compensate for this, the T 761 can slightly delay the audio sent to the center and rear (closer) speakers. In this way, when playing Dolby Digital or Dolby Pro logic soundtracks, the sound from all speakers arrives uniformly at the listening position as intended by the film's producer.

Each millisecond corresponds approximately with 1 foot or 30.5 centimeters.

NOTE:

The channel delay option is not available in DTS surround mode. To set the center channel delay time:

• Call up the SETUP menu of the On Screen Display.
• Select the CHANNEL DELAYS menu.
• Choose CENTER and select the desired delay time (1, 2, 3, 4 or 5ms).

Measure the distance from the listening position to the center speaker (dC) and to one of the front speakers (dFL or dFR). Subtract the center channel distance from the front L or R channel distance. For example, if the front speakers are 12 feet (3.7m) from the listening position and the center speaker is 10 feet (3.0m) , the difference is 2 feet (0.6m) . For this example the center channel delay is set to 2 milliseconds or ms.

The T 761 can delay the center channel output up to 5 milliseconds and thus compensates for center channel speakers that are up to 5 feet (1.5 m) closer to the listening position than the front left and right speakers.

NOTES:

In rare system setups, the center channel speaker is actually further away than the front left and right speakers. In these cases, set the center channel delay to 0mS . The center channel delay time adjustment is only available in Dolby Digital surround mode.

To set the rear channel delay time,

• Use the or cursor button (No. 7) to highlight the REAR.
• Scroll the preset delay time options by and cursor buttons.

Measure the distance from the listening position to either the left or right rear speaker (dLS or dRS). Subtract the rear speaker distance from the front speaker distance (dFL or dFR). The resulting distance is equivalent to the delay in milliseconds for the rear delay setting. For example, if your rear speaker distance is 6 feet (1.8m) and the front distance is 12

feet (3.7 m), the correct rear channel delay setting is 6 milliseconds. Again, set the rear channel delay to 0mS if the rear channels are further from the listening position than the front speakers.

In Dolby Digital surround mode, the rear channel delay time can be set from 0ms to 15ms with 1ms increments.

In Dolby Pro logic surround mode, the rear channel delay time can be set from 15ms to 30ms and 1ms per step. In DTS surround mode, the channel delay time cannot be adjusted.
- When both delays have been entered, choose "SAVE & EXIT" to save the settings and return to the Main Menu.

Channel Balance:

The output levels of each of the speakers connected to the T 761 may need to be adjusted so that there is an even balance of sound from all the speakers in the system. If, for instance, the relative volume level to the Left and Right speakers and the center speaker is set too low, most of dialogue may be difficult to follow. If, on the other hand it is set too loud, the overall balance will sound unnatural.

To adjust the channel balance the T 761's remote control is equipped with a TEST button to help assess the loudness levels of each speaker. Before adjusting the channel balance level make sure the master volume is turned down to a normal listening level.

Pressing the TEST button engages the Test signal generator to allow for adjustment of all speaker levels, so that each channel can be adjusted for equal loudness at your listening position. The test signal scrolls automatically with 5 second intervals from Left, Center, Right, Rear Right, Rear Left, to subwoofer in continuous cycles. If an adjustment in setting is made for one of the speakers, scrolling will stop until 5 seconds after the adjustment was made. Both display panel and OSD show which speaker is being fed with the test signal. Use the cursor and button to respectively increase or decrease the level for the current speaker.

NOTE:

There is no output in the Subwoofer during noise sequencer operation; therefore it is difficult to adjust the level in test mode. The Subwoofer level can be adjusted in the OSD setup menu with musical input.

The Channel Balance for each speaker can be adjusted in 1dB increments. Continue to calibrate the level for each speaker until equal loudness is achieved at your listening position. A more accurate adjustment can be made using a sound level meter, if available. Set the meter to "Slow" and "C-weighted" modes and re-check the settings with the meter placed in several different positions in the general listening area.

Press the TEST button again to leave or cancel the Test mode, any changes will be memorized automatically.

The loudspeaker levels can also be individually adjusted with the OSD setup menu:

• Call up the SETUP menu of the On Screen Display.

Select the channel for which you wish to adjust and set the level so that it matches the other speakers. For best results it is best to start with the Left channel set at 0dB and to match the other speakers to it. Normally, if the Right speaker is located at the same distance from the listening position to the Left speaker it should be set at the same level as the Left speaker.

NOTE:

If no level adjustments were made, press TEST again to return to the selected source. Any changes in the Channel Balance Setting, under the test mode, will be memorized automatically.

LFE (Low Frequency Effects, with a Dolby Digital source, the subwoofer channel) can be set from +10dB to -10dB .

The Delay time for the Surround speakers also needs to be correctly set for your normal listening position. Refer to the section "Channel Delay" in this chapter for more information.
