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 pre- amplifier 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 T770’s integrated power amplifier for that channel.

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 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 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 T770’s 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 NAD- link. 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.

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 T770’s speaker outputs and the speaker outputs of an external amplifier to the same speakers.

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 amplifier’s 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.
