The surround processor requires the following two adjustments to produce the maximum
surround sound effect:

Step 1 Press the TEST button.
The test tone will move clockwise from speaker to speaker,
Step 2 Adjust the center channel level using the CENTER LEVEL buttons. Adjust the rear
channel level using the REAR LEVEL buttons.
You can adjust these levels in 2 dB units within a range of +20 dB. The sound levels
of the left and right speakers should be the same.
Step 3 Press the TEST button.
The test tone will cease.
NOTES:
* If “PHANTOM” is selected as the center channel mode, the CENTER LEVEL bution
is disabled.
* When you are not using rear speakers, you can adjust the center channel level after
selecting “3CH LOGIC" program. In this case, the REAR LEVEL button is disabled.
* It is covenient to use the remote while sitting in your listening position.

listening position and different sets of speakers. Delay time can be set in 3 steps.
