12. S-VIDEO VIDEO 1, VIDEO 2, VIDEO 3, VIDEO 4, MONITOR OUT 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 T770 in the same way as described with the Video composite equivalents (No. 9, 10 and 11 above).
NOTE: The MULTI SOURCE PRE OUT will only pass on input signals connected to the analogue inputs. It makes sense therefore to also connect the analogue outputs of your CD, DVD, and Laser Disc player if these are already connected to any of the digital inputs. 15. AUDIO PRE-OUTS The NAD T770 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 T770 as a preamplifier to drive external power amplifiers. This way, you use all the control functions the T770 provides, such as input select, surround mode, volume, tone controls, etc., but the external power amplifier actually powers the speaker connected it instead of the T770s 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. When using external power amplifiers connected to the Audio Pre-Outs make sure Speakers A (No. 4 on front panel drawing) are engaged. NOTES: Never connect the T770s speaker outputs and the speaker outputs of an external amplifier to the same speakers.
A video signal fed to an S-Video input socket will be available on both the S-Video and Video composite output of Monitor Out. However, a signal fed into one of the Composite Video inputs will only be available on the Video composite outputs of Video 1, Video 2 and Monitor Out.
An S-Video signal is not available as a composite Video signal on either the Video 1 and Video 2 outputs. If both the S-video and Video composite signals are connected to either VIDEO 1, VIDEO 2, VIDEO 3, VIDEO 4 or VIDEO 5, the Video composite signal will be available on both the VIDEO 1 and VIDEO 2 outputs. A video signal connected to VIDEO 1 or VIDEO 2 will not be available on its own video output. 13. 5.1 CHANNEL INPUTS Inputs for the multi-channel audio signals from an external decoder, such as a DTS* decoder or DVD player with integrated decoder. Use two twin RCA-to-RCA lead to connect the decoders front left and right Audio Outputs to the Front left and right inputs, and the decoders Surround left and right outputs to the Surround left and right inputs. Use a third twin RCA-to-RCA lead to connect the decoders subwoofer output to the Subwoofer input and the decoders Center channel output to the Center channel input. Make sure you to follow colour 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. 14. MULTI SOURCE PRE-OUT The MULTI SOURCE PRE-OUT sockets will allow you to channel the signal from any of the T770s input sources to an external power amplifier or sound system, independent from the source chosen to listen to on the T770 itself. By using a so-called remote control repeater system you can use the T770 remote control in the other room and adjust volume and source independently from volume set and source chosen in the main room. Remote Control repeater systems are available from brands such as e.g. Xantech and QED. Consult your dealer on the availability and use of such systems. If the system in the second room is equipped with NAD-link, such as the NAD C320 or C340 amplifier, the T770 can be connected through NADlink. This enables it to receive remote control commands from the second room without the need for a Remote Control Repeater system. Fig. A illustrates how the connections are made to use the MULTI SOURCE PRE OUT sockets.

Before making any connections, check that the T770 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. 16. SUB WOOFER 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 subwoofers). NOTE: When headphones are inserted the signal from the Subwoofer output will be muted. When speakers B is selected the Subwoofer output will also be muted. 17. SOFT CLIPPING When an amplifier is driven beyond its specified power output, 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 minimise 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 amplifiers power capability, then switch Soft Clipping on. 18. FRONT SPEAKERS A & B The Front A and B speaker outputs are switched on and off respectively by using the Speaker A and Speaker B button on the front panel. Use the SPEAKER Front A, CENTER and SURROUND connections for a surround sound set-up. Use the SPEAKER FRONT B connections for an extra pair of speakers to be used for a different listening area such as a dining room or kitchen, for instance. No surround sound modes are available when Speakers B are selected. NOTES: Speakers B can not be engaged if the EXT. 5.1CH input has been selected. Speakers A and Speakers B can not be used simultaneously. When selecting Speakers B, Speakers A will be disengaged and vice versa. 9
CONNECT THE SPEAKERS Connect the right speaker to the terminals market R + and R - ensuring that the R + is connected to the + terminal on your loudspeaker and the R - is connected to the loudspeakers - terminal. Connect the terminals marked L + and L - 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 T770. Unscrew the speaker terminals plastic bushing. Insert the pin or bare cable end into the hole of the terminal and then secure the cable by tightening down the terminals bushing (Fig. 4). 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 or pin and no loose strands of speaker wire. NOTE: This unit is designed to produce optimum sound quality when speakers with impedances within the sets ranges are connected. Please check the following information and choose speakers with the correct impedances for the connections. FRONT SPEAKERS A or B: 4 ohms min. per speaker CENTER SPEAKER: 4 ohms min. SURROUND SPEAKERS: 6 ohms min. per speaker 19. CENTER SPEAKER This connects the center loudspeaker that is used when the T770 is operated in Dolby* Digital, Dolby Pro Logic, EARS surround sound mode or with the EXT. 5.1 CH input selected. Connect the CENTER speaker in the same way as described in the section Connect the speakers above (section 18). 20. SURROUND SPEAKERS This connects the Surround loudspeakers that are used when the T770 is operated in Dolby Digital, Dolby Pro Logic, and EARS Surround sound modes or with the EXT. 5.1 CH input selected. Connect the SURROUND speakers in the same way as described with SPEAKERS A & B above (section 18).

24. AC OUTLETS (120V North American versions only) The AC power cords of other units in the audio system can be connected directly to the T770s AC outlets. If another stereo component is plugged into the SWITCHED AC outlet, power will be supplied to that component only when your T770 is turned on. If another stereo component is plugged into the UNSWITCHED AC outlet, power will be supplied whether your T770 is on or off. NOTE: The AC outlets should be used with units with a COMBINED power consumption of no more than 120 Watts. 25. DIGITAL AUDIO INPUTS (FIG. B) The T 770 has three digital inputs to allow for connection of DVD, CD or Laser Disc players: 1. Digital Audio input 1 allows for connection of a digital source with an Optical output. Use a cable terminated with a TOS Link connector. This digital input can be selected and linked with any of the analogue inputs, with the exception of the EXT 5.1 CH. input. 2+3. Digital Audio inputs 2 and 3 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. This digital input can also be selected and linked with any of the analogue inputs, with the exception of the EXT 5.1 CH. input. NOTE: The sound of the digital inputs is not passed on to the Multi Source, Video 1, Video 2, Tape 1 and Tape 2 outputs. If available, also connect the analogue outputs of the digital sources as well to the matching analogue inputs of Digital input 1, 2 and 3. FRONT PANEL CONTROLS POWER, SPEAKERS AND HEADPHONE FUNCTIONS 1. POWER Press the POWER button to switch the receiver to its Stand-by mode. The Stand-by indicator (No. 2) over the power button will light up. On the front panel, press any of the input selector buttons (No. 6) to switch to receiver on. From the remote control, press the green Stand-by button (No. 1 on remote control drawing) to switch the unit on. 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 T770 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.
21. COOLING FAN The cooling fan allows T770 to deliver high amounts of power without the unit becoming too hot. The fan will only operate in Surround Sound mode operation during loud passages coming from the surround channels. With No Surround mode selected (stereo), the fan is inoperative. NOTE: Ensure that the air outlets of the fan arent blocked in any way. 22. NAD-LINK IN OUT The NAD-Link connector is used to pass commands from other units fitted with NAD-Link connectors. This allows centralised control of a complete system, and also allows some of the basic functions of other NAD components (such as a CD player or cassette deck) also equipped with NAD-Link to be controlled with the receivers remote control. To function with such other units, connect the T770s 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. 23. AC POWER CORD After you have completed all connections to the amplifier, plug the AC line cord into a live wall socket.

6. INPUT AND MONITOR SELECTORS These buttons select the active input to the T770 and the signal sent to the loudspeakers, Tape 1 & 2, Video 1 & 2 and TV monitor outputs. The name of the Input and Surround Mode will be shown in the Display Panel. VIDEO 1 & VIDEO 2 Selects the VCR connected to VIDEO 1 or VIDEO 2 as the active input. VIDEO-1 or VIDEO-2 is shown in the Display Panel when selected. VIDEO 3 & VIDEO 4 Selects the signal from stereo TV/Satellite/Cable receiver or Laser Disc connected to VIDEO 3 or VIDEO 4 as the active input. "VIDEO-3" or "VIDEO-4" is shown in the Display Panel when selected.VIDEO 5 Selects the camcorder or video game console connected to the Video 5 front panel inputs as the active input. VIDEO-5 is shown in the Display Panel when selected. VIDEO 5 Selects the camcorder or video game console connected to the Video 5 front panel inputs as the active input. VIDEO-5 is shown in the Display Panel when selected. TAPE 1 Selects Tape 1 as the active input. TAPE 2 MONITOR Selects the output from a tape recorder when playing back tapes or monitoring recordings being made through the Tape 2 sockets. Press the Tape 2 button once to select it and again to return to the normal input selection. Tape 2 is a Tape Monitor function, which does not override the current input selection. For example, if the CD is the active input when TAPE 2 is selected, then the CD signal will continue to be selected and sent to the TAPE 1, TAPE 2, Video 1 and Video 2 OUT sockets, but it is the sound from recorder connected to Tape 2 that will be heard on the loudspeakers. When Tape 2 Monitor is selected, TAPE 2 is indicated in the alphanumeric section of the display for 3 seconds before it defaults to indicating the active input again. The box just over the alphanumeric section indicating T-2 MONITOR will remain lit until Tape 2 is disengaged again. FM Selects FM radio. FM is also automatically selected when an FM Preset is selected. AM Selects AM radio. AM is also automatically selected when an AM Preset is selected. AUX Selects the auxiliary audio component as the active input. CD Selects the CD as the active input. VIDEO OUTPUT The video signal available on the S-Video and Video Composite Monitor, Video 1 and Video 2 outputs is dependent on the selected video input (VIDEO-1, VIDEO-2, VIDEO-3, VIDEO-4, VIDEO5). However, when one of the audio-only sources is selected (TAPE1, TAPE-2, FM, AM, AUX, CD) the last selected video signal from one of the video inputs will be present on these outputs. This way you can watch a Laser Disc or video whilst listening to the CD player. The display indicates which video signal is routed to the MONITOR, Video 1 and Video 2 outputs in the far left of the display area. NOTE: To avoid feedback the video input signal from Video 1 or Video 2 is not available on their own outputs (e.g. When Video 2 is selected, the video signal will be available on the Monitor and Video 1 outputs, but not on the Video 2 outputs). VOLUME AND TONE FUNCTIONS

5. VIDEO 5 INPUT For easy and temporary connection you can connect a camcorder (playback only) or video game console. If the game console or camcorder is mono, connect the audio lead to the R (Right) audio socket. If your camcorder is equipped with S-Video (so-called Hi-8 and S-VHS models) cameras you can use the S-Video input. Refer also to chapter Rear Panel connections, section 12 for additional information. The Video 5 input works in the same was as Video 3 and Video 4, refer to chapter Rear Panel connections, section 10 for additional information.
7. TONE DEFEAT The Tone Defeat switch by-passes the tone control section of the T770. If the Tone Controls (No. 8) are not normally used and left in the 12 oclock position, then it is advisable to switch out the Tone Control section altogether by using this switch. In the out position, the Tone Control circuits are active, pushing the Tone Defeat switch in bypasses the Tone Control section.
8. BASS & TREBLE CONTROLS The T770 is fitted with BASS and TREBLE tone controls to adjust the overall tonality of your system. The 12 oclock position is flat with no boost or cut and a detent indicates this position. Rotate the control clockwise to increase the amount of Bass or Treble. Rotate the control anti-clockwise to decrease the amount of Bass or Treble. These controls affect the Left, Right Front and Center 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). 9. VOLUME The Volume control adjusts the overall loudness of the signals being fed to the loudspeakers. It is motor driven and can be adjusted from the remote control handset using the Master Volume or button (No. 8 in remote control drawing). The Volume control does not affect recordings made using the Tape 1, Tape 2, Video 1 and Video 2 outputs but will affect the signal going to the Pre-amp output (Audio Pre Out). On the remote control handset, press the Mute Button (No. 3) to temporarily switch off the sound to the speakers and headphones. Mute mode is indicated by AUDIO MUTE flashing in red in the display area. Press Mute again to restore sound. Mute does not affect recordings made using the Tape 1, Tape 2, Video 1 and Video 2 outputs but will affect the signal going to the Pre-amp output (Audio Pre Out). NOTES: The Volume control does not affect the volume of the Multi Source output. Use the Multi Source Level buttons on the remote control (No. 6 in remote control drawing) to adjust the Multi Source volume. Depending on the calibration of the Surround Setup it may occur that the volume control can not be adjusted to its maximum position. Even if it is turned to the maximum position, it will return to its highest possible setting. TUNER

The next time this input is selected, the chosen Digital Audio input will automatically be selected as well. NOTES: It is not possible to select a digital input if Digital Audio input 1, Digital Audio input 2 and Digital Audio input 3 have already been assigned. You must first de-select the desired Digital Audio input from the Input Selector button it has been assigned to. TO DE-SELECT A DIGITAL AUDIO INPUT Select the input to which the Digital Audio Input is assigned (the display indicates which Digital Audio Input is assigned to the selected input). Press the Digital Audio Selector until the Digital Audio extinguishes in the display. The Digital Audio input has now been de-selected from the chosen input. When no digital source is available (not connected or source is switched off) the associated Digital Audio input number will blink. Once a digital signal is available and the input has locked on to the digital signal it will remain lit. 19. SURROUND MODE With the Surround Mode and buttons the available surround sound modes can be selected. The selected Surround mode is permanently indicated in the display area and is also shown for 3 seconds in the large alphanumeric section of the display. The Surround Mode buttons scroll through the available surround sound modes: Surround Mode Off Surround mode Off, etc. Dolby Pro Logic EARS
With Dolby Digital surround sources Dolby Pro Logic and EARS are not available: Surround Mode Off Dolby Digital. If Dolby Pro Logic or EARS is selected the T770 will automatically switch to Dolby Digital. Dolby Digital has six independent channels available in total: Left, Center, Right, Surround left, Surround Right and an Effects Channel (Subwoofer). Dolby Digital is only available as a Surround Mode if the source is Dolby Digital and a Digital Audio input is used. The Dolby Digital signal conforms to Dolbys AC-3 standard, which allows for several channel configurations. The channel configuration is shown the display together with the input selected. For example, with regular Dolby Digital sources the display will show ch3/2, indicating that there are 3 front channels and 2 surround channels available.
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 Ambience 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. Surround Mode Off switches to normal Stereo operation. NOTE: When using Digital Audio Input 3, the Surround Mode Off is selected, the analogue inputs will be selected. Therefore, ensure that the analogue outputs of the digital sources are connected as well to the same input the Digital Audio input has been assigned to. As an additional convenience feature, your T770 memorises which surround mode you have used with the given input selection. When you next select that input, your T770 will automatically choose the same Surround mode again. If normally you use Dolby Pro Logic mode on the Video 1 and Video 2 inputs, Dolby Digital on the Video 4 input, EARS on CD and By-Pass (Stereo) on the others, pressing the Input Selector will automatically default to the right Surround mode without having to separately press the Surround Mode button. NOTES: An external source such as a decoder or DVD player with a decoder built-in (DTS, MPEG for instance) can be connected to the EXT. 5.1 CH input (No. 5). When the EXT. 5.1 CH input is selected, no other surround modes are available, so SURROUND MODE extinguishes in the display panel. To obtain the best surround sound possible it is important that all speakers have been set up correctly. Refer to the chapters On Screen Display and Setting up the Surround System. 20. MULTI SOURCE The NAD T770 allows you to change source and alter volume for another room by remote control, independently from the main listening room. This means you could be enjoying a DVD in Dolby Digital Surround Mode CD in the main room and somebody else to a radio broadcast in another room at the same time. Full operation of the Multi Source facility, such as changing volume, is possible only with remote control. It is possible however to change the source for a second room by using the Multi Source button on the front panel in the same way as it is used on the remote control: On the remote control, press Multi Source (No. 5). The MULTI SOURCE indicator in the display will flash. While the MULTI SOURCE indicator is still flashing (8 second default time) select the desired source on the remote control. The selected source will be indicated in the display by a box around it. If you want sound in just the second room and not in the main room, disengage either Speakers A or Speakers B on the front panel (No. 3) or the remote control. Adjust the volume for the second room setting by pressing either the or MS VOLUME button (No. 6) on the remote control. Upon adjusting the Multi Source level, the display will indicate MULTI and the corresponding level setting (ranging from -78 to 0 dB). NOTES: As it is possible to use the Multi Source facility independent from the main listening room, an extra remote control handset can be useful. Your NAD dealer can advise you regarding the availability. With the Multi Source facility in use, the source indicated in the main display for the main listening room can be recorded from.

ON SCREEN DISPLAY (OSD) The NAD T770 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 T770. For 230V versions only; not on 120V (North American versions): 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. 14), press the Video 1 input selector button (No.6) repeatedly until the desired system is shown in the display area. If your television and your sources are multi-standard it is recommended you choose the OSD AUTO option. In this case the T770 will automatically select the system used by the connected video input signal. The OSD can be engaged by pressing one of the four cursor buttons on the remote control (No. 9). The main menu will appear (see Fig. 6).
Use the cursors buttons on the remote control to navigate, select the desired menu and options. The and buttons are used to navigate and select an option (indicated by highlighting the available option), the and buttons to change a setting from the highlighted section. Selecting EXIT from the Main menu will switch the OSD off. Selecting EXIT from any of the other menus takes you to the previous menu. The OSD menu are at maximum three layers deep; this means that from the main menu (layer 1) you can select a sub menu (layer 2), from which you can again select a submenu (layer 3). The number of starts left and right of the menu header indicates which layer is displayed; 1 star for layer 1, 2 stars for layer 2, 3 stars for layer 3. There are various ways in which the OSD can appear and function: From the Main menu select and enter the Screen Setup menu (see Fig. 7). Select Superimpose = ON so that the OSD is superimposed over the video signal received from the T770 input selector. By selecting OFF the OSD will always be displayed with a solid blue background. Select Temporary Display = ON if you wish to see the OSD confirming each time an operation is performed for 5 seconds (such as volume change, different input selected, etc). By selecting OFF the OSD will only be shown when calling up the Main menu.
The other Menus available are: INPUT SELECTOR (FIG. 8) When calling the INPUT SELECTOR up for the first time, both Picture and Audio will be highlighted. By using the or cursor button you can scroll through and choose one of the inputs. It is also possible to select the video input signal independent from the audio input signal.
SPEAKER A SETUP With the Speaker A Setup mode (Fig. 12), you can select submenus to set all parameters for a surround sound system:
Speaker Selection (Fig. 13); Speaker Distance (Fig. 14); Level Calibration (Fig. 15).

With both Picture and Audio highlighted, select first the desired video signal. Press the cursor button once so that only Audio is highlighted. You can now select the input for sound only; e.g. even if you have selected the picture of Video 4 you can still choose to hear the sound from the Video 2 input. Within this menu you can also select to switch Tape 2 Monitor on or off; scroll through the available Digital Audio inputs; change the surround Mode. If the selected audio input is the tuner, another submenu (layer 3) is available which will allow Bank and Preset selection (Fig. 9)
SURROUND SETUP (FIG. 10 & 11) In the Surround Setup menu the desired Surround Mode can be selected. With a Dolby Digital source you can choose between Dolby Digital Surround mode or Surround mode off. (Fig. 10) Refer also to chapter Setting up the Surround Sound System. SPEAKER B SETUP In the Speaker B Setup menu the balance between the Left and Right channel can be changed (Fig. 16). The small two vertical bars indicate the relative loudness of the left channel to the right and vice versa. With the directly below the symbol, balance is set exactly in the middle. With Dolby Digital selected you can also select Late Night on or off, and LFE Level Atten at 0dB or -10dB (Fig. 11).
NOTE: The OSD will switch itself off if no option selected or setting changed for more than five minutes. Refer also to chapter Setting up the Surround Sound System. 15
STORING, RECALLING AND NAMING PRESETS TO STORE A PRESET Tune to the radio station you wish to enter into a Preset (refer to chapter Front Panel Controls section 15). 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 nonRDS station is found, then just the frequency will be shown. To store that station as a Preset, press Memory (No. 14). The Memory indicator will be displayed and the Preset section will flash in the Display Panel. Press Bank (No. 12) to select which of the four Banks of Presets (A, B, C or D) you want to store the station into. Press either the Tune/Search or button to select which Preset number you wish to assign to the station (from 1 to 10), shown as a flashing number in the Display Panel, and then press Memory (No. 14) again. The Memory light in the Display Panel will go out and the station is now stored in your NAD T770s memory. To exit the Memory mode without storing a station, leave all the tuner controls untouched; the Memory mode will automatically cancel itself after 8 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 overwrite 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 button (No. 13) until PRESET lights up in the display. By pressing the Bank button (No. 12) select which Bank of Presets you want to use (A, B, C or D, indicated in the display). Press either the Tune/Search or buttons (No. 15) until the right Preset is found and shown in the Display Panel. NOTE: Any unused Presets will be skipped and it is not possible to select a Bank unless it has at least one Preset stored into it.

11. MODE (SURROUND) The Mode button scrolls through the available surround sound modes. This button functions in the same way as the right section of the Surround Mode buttons on the T770 front panel (No. 19 front panel drawing). Refer also to chapters Front Panel Controls, section No. 19, On Screen Display and Setting up the Surround Sound system for more information. 12. TEST Pressing the Test button engages the Test generator to allow for adjustment of all speaker levels, so that each can be adjusted for equal loudness at your listening position. The Display Panel shows which speaker is being fed with the test signal. Press again to cancel the Test mode. Use the Channel Select button (No. 13) and Level buttons (N0. 14) to access and adjust the relative level of each channel. Refer also to chapter On Screen Display and Setting up the Surround Sound system for more information. 13. CHANNEL SELECT Use in combination with the On Screen Display in SPEAKER A SETUP or with Test function (N0. 12) engaged. (refer also to chapter On Screen Display and Setting up the Surround Sound system for more information). Each successive press of the button causes the T770 to scroll to the next channel: Left Center Right Right Surround Left Surround Subwoofer Left, etc. The display panel on the T770 also indicates which channel is selected. Use either the Level or (No. 14) to change relative volume level for the desired channel. Refer also to the chapter Setting up the Surround Sound system for more information. 14. LEVEL With the Level or buttons the relative volume level trims for Center, Left and Right Surround channels can be adjusted. Press the Channel Select button (No. 13) to select the channel for which you wish to adjust the level. Refer also to the chapter Setting up the Surround Sound system for more information. Other than the commands relating to the NAD T770 receiver itself, there are other buttons which will operate most NAD CD players and Cassette decks equipped with NAD Link. 15. CD PLAYER CONTROL (for use with NAD CD Player) engages Pause. engages Stop. engages Play or toggles between Play and Pause. or engages Track skip; Press once to respectively go to the next track or to return to start of current or previous track. DISC Go to next disc (for NAD CD changers).

Press to put cassette deck into recordpause. Press Play to start recording. Stops Play or Recording. engages Rewind. engages Fast Forward. 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. SETTING UP THE SURROUND SYSTEM To obtain the best results in any of the Surround Modes it is important that the T770 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 is connected to the T770 monitor output. Refer to the chapter On Screen Display (OSD) on how to access the Main Menu of the On Screen Display, choose sub-menus and change settings. The setup procedure is broken down in three sections: 1. Speaker Selection 2. Speaker Distance 3. Level Calibration SPEAKER SELECTION First you need to indicate which speakers are connected to your T770. These can include a Center, two Surround speakers and a subwoofer, apart from the Left and Right speakers:

For best results, you should consider using a center speaker. Ideally it should be the same type as the left and right speakers, although there are now many new speakers, such as the NAD 808CC, which are specifically designed as center channel add-ons for existing stereo systems. Choose Sur. and select YES if you do have surround connected, NO if you dont have surround speakers connected. 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 come close 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. Choose Subwf. and select YES if you do have a subwoofer connected, NO if not. Many film soundtracks rely heavily on very low frequency sound effects that 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 T770 is designed specifically to drive a sub-woofer 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. SPEAKER DISTANCE For the best surround sound performance it is important that sound of all speakers reach the listeners ears at the same time. Because the Surround speakers are usually closer to the listener than the Front speakers, there is a 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 Left and Right speakers.
Call up the Main menu of the On Screen Display (Fig. 6). Select the Speaker A Menu (Fig. 12). Choose the Speaker Selection submenu (Fig. 13). Choose Center and select one of the three modes available appropriate to the T770s setup: Small, Large, None.

The Small mode is used when the center speaker is smaller than the front left and right speakers. This mode produces a true center image with the very low frequencies (below 70 Hz) filtered out. The Large mode is used when the center speaker is similar in size and power handling as the front left and right speakers. This mode produces a true center image with a full frequency range and no low frequency filtering. The None mode is used when there is no center speaker installed. The T770 places the center information equally on the left and right front speakers so producing a Phantom central sound image. 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 stabilises the stereo image, making the usable listening area much bigger. 18
To resolve this problem, the T770s circuitry includes a system that will delay the signal for the speaker closest to the listener. This ensures sound coming from all speakers always arrives at the listeners ears at the correct time. To set Speaker Distance: From the listening position, measure the exact distance to each speaker. Call up the Main menu of the On Screen Display (Fig. 6). Select the Speaker A Menu (Fig. 12). Choose the Speaker Distance submenu (Fig. 14). Select Front and enter the distance in either feet or metres. Depending on the version of your T770, you can change the distance in feet or metres with 1 foot or 0.3 metre increments from 1 (0.3m.) to 30 foot (9.0 m.). Select Centre (if installed) and again enter distance. The Center speaker must be within 2 metres in distance compared to the Left and Right speakers. Select Sur. (if installed) and enter distance again. The surround speakers should not be further away from the front channel speakers. LEVEL CALIBRATION The output levels of each of the speakers connected to the T770 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 the center is set too low, most of dialogue may be difficult to follow. If, on the hand it is set too loud, the overall balance will sound unnatural. To facilitate the Level calibration procedure the T770 is equipped with a Test signal generator to help asses the loudness levels of each speaker. Before starting the Level Calibration procedure make sure the master volume is turned down to a normal listening level. Call up the Main menu of the On Screen Display (Fig. 6). Select the Speaker A Menu (Fig. 12). From the listening position, choose the Level Calibration submenu (Fig. 15). The T770s built-in test signal generate will start the noise signal that scrolls to each of the speaker channels: Left Center Right Right Surround Left Surround Subwoofer Left etc. 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. The Level for each speaker can be adjusted in 1dB increments. Continue to calibrate the level for each speaker until for 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.

If a Sub-Woofer is used on the system, adjust the Sub-Woofers level control so that it is audible, but does not dominate the sound. The Level settings are stored in the T770s memory. They are automatically recalled when the unit is switched on. Depending on the software played back on the T770 is may sometimes be desirable to make minor adjustments to the level of the Center, Surround speaker or subwoofer. Instead of through the OSD Speaker Setup procedure it is also possible to access Level Calibration direct: Make sure the volume is set to a normal listening level. On the remote control, press the Test button (No. 12). The test signal is now audible through the Left speaker. Press the Channel Select button (No. 13) to select the speaker for which you wish to adjust the level. Each successive press of the button advances the sound of the Test generator to the next speaker: From Left Center Right Right Surround Left Surround Subwoofer, etc. It is indicated in the display area which speaker has been selected. Press the Level or button (No. 14) to adjust the level for the selected channel. Once adjustments have been made, press Test again. the test generator will switch off and normal operation will resume. NOTE: The Test generator will switch itself off if no level adjustments were made for more than two minutes. LFE (Low Frequency Effects, with a Dolby Digital source the subwoofer channel) can be set from the normal mode 0dB to a lower level -10dB. If the bass from the subwoofer is too loud, set the LFE option to -10dB. The Delay time for the Surround speakers also needs to be correctly set for your normal listening position. Refer to the section Setting the Surround Delay in this chapter for more information.
