Clearing Presets - NAD 713 Owner's Manual

shown in the Display Panel. The AV 713 only pages
through Presets that are tuned to stations and will
skip past empty Presets.

CLEARING PRESETS.

First select the Preset station. Hold down the MEM-
ORY button and press the FM MUTE/MODE button.
The Preset number will then disappear from the
Display Panel and the Preset will be emptied.
SLEEP AND MUTE FUNCTIONS
Buttons for the SLEEP and MUTE functions only
appear on the Remote control.
SLEEP
Press SLEEP to make the AV 713 automatically
switch off after a preset number of minutes. Pressing
the SLEEP button once will set the sleep time to 90
minutes, after which the AV 713 will automatically
switch off into Standby mode. Sleep mode and the
Sleep delay is shown on the Display Panel. To adjust
the Sleep Delay, hold down the SLEEP button. This
will reduce the sleep time in 10 minute increments, as
shown in the Display Panel. To cancel the Sleep
mode, continue pressing the SLEEP button until the
source name appears in the Display Panel. Pressing
the POWER button will also cancel the Sleep mode.
MUTE
Press the MUTE Button to temporarily switch off
the sound to the speakers and headphones. Audio
Mute indicator will flash in the Display Panel when the
unit is in Mute mode. Press MUTE again to restore
sound
SETTING UP THE SURROUND SYSTEM.
To work at its best, the output levels of the AV
713's surround facilities need to be adjusted so that
there is an even balance of sound from all the speak-
ers in the system. The Delay time for the Surround
speakers also needs to be correctly set for your nor-
mal listening position.
The adjustment of speaker levels is done using the
Test and Speaker Level adjust functions on the
Remote Control.
It is important first to correctly phase all the speak-
ers in the system. Check that the positive (+) termi-
nals of the amplifier speaker outputs are connected to
the positive (+) connector on the each of the speak-
ers.
Before starting the set-up procedure, ensure that
the CENTER Mode is set correctly for your speaker
configuration. TONE DEFEAT should be ON and the
BALANCE control set to the position normally used
for stereo sources (usually the 12 o'clock position).
USING TEST TO SET UP THE SURROUND
SYSTEM LEVELS.
With the speakers connected and the VOLUME
turned down to zero, select DOLBY PRO LOGIC
MODE, SPEAKER A and press TEST on the Remote
Control. This generates a test signal that is fed to
each of the speaker channels in turn (left, center,
right and surround), 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 ÒÚ buttons 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
continue 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 ÒÚ buttons on the
Remote Control. The adjustment will affect the level
of both surround 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 ten-
dency 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 speak-
ers 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 sur-
round speakers and the listening position in the room.
First make a note of the distance between the sur-
round speakers and the listening position. Now make
a note of the distance between the front speakers
and the listening area. Use the graph below and note
where the two distances intersect. This will give the
recommended Delay setting.
To adjust the Delay setting, put the AV 713 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 713'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.
