Remote Control. This generates a test signal that is
fed to each of the speaker channels in turn (left, cen-
ter, right and surround for Dolby Pro Logic, left,
center, right for Dolby 3 Stereo), 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.

Turn the VOLUME up until the signal is moderately

loud through the left and right speakers. When the
Test signal reaches the Center speaker, press the
CENTER VOLUME

button on the Remote

Control to adjust the Center speaker’s loudness so
that it matches the levels being produced by the left
and right speakers. The relative level of the Center
channel is shown in the Display Panel and can be
changed in dB steps. Below -20dB the increments
become progressively coarser.

When you have finished adjusting the level of the

Center channel, the Test signal will automatically con-
tinue switching between the speakers. If you are
unhappy with your initial setting, repeat the procedure
until the levels match.

Repeat the operation to set the surround speaker

level using the REAR VOLUME

button on

the Remote Control. When selecting Dolby Pro Logic
modes, the adjustment will affect the level of both sur-
round speakers simultaneously.

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-Woofer’s level control so that it is audible, but
does not dominate the sound. Sub-Woofer levels can
be later fine-tuned using programme material.

SETTING THE SURROUND DELAY.

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. To resolve this problem, the
Dolby Pro Logic circuit includes a Surround delay.
This ensures sound coming from the surround
speakers always arrives at the listener’s ears after the
sound from the front speakers.

The exact amount of delay required depends on the

relative distances between the Front and surround
speakers and the listening position in the room.

First make a note of the distance between the

surround speakers and the listening position. Now
make a note of the distance between the front
speakers and the listening area. Note where the
two distances intersect this will give the correct
Delay setting (see Page 5).

To adjust the Delay setting, put the AV 711 into

Dolby Pro Logic mode and press DELAY on
the front panel or the Remote Control. Continue
pressing DELAY until the correct value is shown in
the Display Panel.

Level and Delay settings are stored in the AV 711’s

memory. They are automatically recalled when the
unit is switched on.

For your reference, use the boxes overleaf to make

a note of your settings. If they are accidentally
altered, you can reset them without having to run the
Test procedure.

REMOTE CONTROL

The 45RC1 Remote Control handles all the key

functions of the AV 711 and has additional controls to
remotely operate NAD Cassette and CD machines. It
will operate up to a distance of 16ft (5m).

The subsidiary mode, and set-up functions have

black buttons. Power, Master Volume and Record (for
an associated NAD cassette deck) are in red.

Refer to previous sections of the manual for

descriptions of individual functions.
