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 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.

The state of test-tone output is shown by the display panel and

the monitor screen. (Especially 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.

MAIN LEVEL switch on the rear panel to "–10 dB", and adjust the

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 in

the display panel. A calibration signal should be heard from the main

speakers and the front effect speakers in turn (see diagram).

remote control so that the speaker volume is the same as that of the

main speakers.

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.
