(Remote Control Only) Center Mode Setting
The center mode setting affects the center channel’s bass signals. It operates
only when you select Dolby Pro Logic Surround Sound. Each time you press
CENTER MODE on the remote control, the setting changes and the receiver dis-
plays: NORMAL , WIDE , PHANTOM , or 3CHLOGIC .
NORMAL — Select this mode if you use a small center speaker. The front left
and right speakers play the center-channel bass sounds.
WIDE — Select this mode if you use a medium or large center speaker. The
center speaker plays the center-channel bass sounds.
PHANTOM — Select this mode if you have no center speaker. All center-chan-
nel sound is sent to the front left and right speakers.
3CHLOGIC — Select this mode if you do not have rear speakers. The rear
channel’s sound is sent to the front left and right speakers.
Test Tone
This feature provides a test tone that lets you balance the signal levels between
all your speakers. See “Center Level” and “Rear Level.”
To activate the test tone, select one of the surround sound modes and set AU-
DIO/VIDEO on the remote control to AUDIO . Then press TEST TONE . The receiver
sounds a 2-second tone from the front left, center, front right, and rear speakers,
in sequence.
Notes:
• The center test tone sounds only when you select the Dolby Pro Logic
Surround (except PHANTOM) or 5-D Pro Logic sound mode.
• In the Dolby 3CH Logic sound mode, the receiver sounds a 2-second
tone from the left, center, and right speakers, in sequence.
Press TEST TONE again to turn off this feature.
Center/Rear Levels
Press CENTER LEVEL –/+ to adjust the center speaker sound level.
Press REAR LEVEL –/+ to adjust the rear speakers’ sound level.
Both CENTER LEVEL and REAR LEVEL work only for the sound system that sup-
ports the center or rear speakers. For example, REAR LEVEL does not work for
Dolby 3CH Logic.
Note: If you do not use a center speaker,
the monaural signals are only repro-
duced if you select PHANTOM.
Note: Use the VOLUME control to adjust
the overall sound level.
