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 loudspeaker’s ‘-’ 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 terminal’s plastic bushing. Insert the pin or bare cable end into the hole of the terminal and then secure the cable by tightening down the terminal’s 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 set’s 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).

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 aren’t 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 receiver’s remote control. To function with such other units, connect the T770’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.

23. AC POWER CORD

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

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 T770’s 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.
