1-4. ADJUSTMENT

MAIN/CENTER/EFFECT SPEAKER LEVEL BALANCE
ADJUSTMENT

This operation uses an internal test-tone generator for balancing

the levels of the main, center and effect speakers.

1. Depress the TEST switch on the remote control so that “TEST
DOLBY SUR.” appears on the display panel to enter test mode. A
hiss-like calibration signal should be heard from the left main
speaker, center speaker(s), right main speaker and rear effect
speakers in turn (see diagram). Adjust the master VOLUME to a
normal listening level.
*

The state of test-tone output is shown by the display panel and
the monitor screen. (On the monitor screen, it is shown by an
image of audio listening room.) This is convenient for adjusting
each speaker level.

2. Adjust the center and rear level by using the CENTER and REAR
LEVEL +/– keys on the remote control so that the sound coming from
the corresponding speakers seems to be at the same level as that
from the main speakers when you are at a normal listening position.
If there is insufficient volume from the effect speakers, you may
decrease the main speaker volume level by setting the MAIN LEVEL
switch on the rear panel to “–10 dB”, and adjust the center and rear
level again. Volume controls on external power amplifiers may also
be adjusted if necessary to achieve proper balance.

3. For the front effect speaker level adjustment, depress the TEST
switch on the remote control again so that “TEST DSP” appears on
the display panel. A calibration signal should be heard from the main
speakers and the front effect speakers in turn (see diagram).

4. Adjust the front level by using the FRONT LEVEL +/– keys on the
remote control so that the speaker volume is the same as that of the
main speakers.

NOTE: If not using a center speaker, be sure to set the CENTER
MODE to the PHNTM (phantom) position.You will then hear the
center channel test tone from the left and right main speakers.

When this adjustment is finished, press the TEST switch once

again.

NOTE: Once you have completed these adjustments, use only
VOLUME control of this unit or MASTER VOLUME keys of the
remote control unit to adjust the whole listening volume. Do not
change any other volume setting in the system.
