Test Tone
The test tone lets you balance the signal levels between all your speak-
ers. To adjust the levels, see “Center Level” and “Rear Level.”
To turn on the test tone, select one of the surround sound modes ( PRO
LOGIC , or 5.1-CH ) then press SURROUND . Then press TEST TONE . The
receiver sounds a 2-second tone from the front left, center, front right,
and surround (rear) speakers, in sequence.
FLch , Cch , FRch , SRch ,
and SLch appear as the test tone sounds.
The center test tone sounds and Cch appears only when you select
Normal , Wide , or 3CH LOGIC .
If you select 3CH LOGIC , the receiver sounds the 2-second tone from the
left, center, and right speakers, in sequence.
Press TEST TONE again to turn off this feature.
Center Level
Press – CENTER LEVEL + to adjust the center speaker sound level.

ers’ sound level.

works in any sound mode.
N N N No o o otttte e e e: : : : Depending on the sound mode you selected, some speaker level
controls do not work. For example, when you select 3CH LOGIC , – REAR
RIGHT LEVEL + or – REAR LEFT LEVEL + does not work.
Delay Time
In the Dolby Pro Logic Surround modes (except 3CH Logic), the receiver
slightly delays the sound going to the rear speakers. You can change
this delay time from 15 to 30 milliseconds (ms) in 5 ms steps. Adjust the
delay time for the best surround effect. As a general guide, each step
corresponds to 3-5 feet in distance. For example, if the surround speak-
ers are 6 feet closer to you than the front speakers, try selecting 20 ms
setting.
Press SURROUND, then hold down DELAY TIME to change the delay time.
The receiver displays the selected time.
Effect Level
With DSP, you can change the delay time to alter the sound effect from
10 to 90. Press
SURROUND , then hold down – EFFECT + to change the effect
level.
The effect can vary depending on the source program.
Notes:
• You must use the remote control to
make these sound adjustments.
• Use the VOLUME control to adjust the
overall sound level.
