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" appears in 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.

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 using the MAIN LEVEL
control on the rear panel and adjust the center and rear level again.
Volume controls on external power amplifiers may also be adjusted if
necessary to achieve proper balance.

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.
After completing this adjustment, press the TEST switch once
again.
NOTE: Once you have completed these adjustments, use only this
unit's MASTER VOLUME control to adjust listening volume. Do not
change any other volume settings in the system.
