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

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.

Note: Use the VOLUME control to adjust the overall 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.
