Using Advanced Sound Options

Sound Mode Adjustments (Remote Control Only)

Note: If you do not use a center speaker, the monaural signals are only repro- duced if you select PHANTOM.

Center Mode Setting

The center mode setting affects the center channel’s bass signals. It operates only when you select the Dolby Pro-Logic Surround or Dolby 3CH Logic mode. Each time you press CENTER MODE on the remote control, the setting changes and the receiver’s corresponding indicator lights: NORMAL, WIDE, or PHAN- TOM Dolby Pro-Logic Surround options, or 3CH LOGIC.

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 cen- ter speaker plays the center-channel bass sounds.

PHANTOM— Select this mode if you have no center speaker. All center-channel sound comes from the front left and right speakers.

Test Tone

The test tone feature provides a test tone that lets you balance the signal levels between all your speakers. To adjust the levels, see “Center Level” and “Rear Level.”

To activate the test tone, select one of the surround sound modes and set AUDIO∙SURROUND on the remote to SURROUND. Then press TEST TONE. The receiver sounds a 2-second tone from the front left, center, front right, and rear speakers, in sequence. The center test tone sounds only when you select the Dolby Pro-Logic Surround or Dolby 3CH 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.

Notes:

•Use the VOLUME control to adjust the overall sound level.

•Set the center mode to a selection other than PHANTOM before adjusting the center level.

Center Level

Slide AUDIO∙SURROUND to AUDIO. Then press – CENTER LEVEL + to adjust the center speaker sound level while in the Dolby Pro-Logic Surround or Dolby 3CH Logic mode.

Rear Level

Slide AUDIO∙SURROUND to SURROUND. Then press – REAR LEVEL + to adjust the rear speakers’ sound level while in the Dolby Pro-Logic Surround or Simu- lated Surround mode.

Notes:

•For Dolby Pro-Logic Surround, the delay is preset to 5 mS.

•The delay time does not affect the Stu- dio Effect mode.

Delay Time

In the Simulated Surround and Dolby Pro-Logic Surround modes, the receiver slightly delays the sound going to the rear speakers. You can change the delay time from 5 to 30 milliseconds (ms) in 2 ms steps. Adjust this for the best sur- round effect.

Slide AUDIO∙SURROUND to SURROUND. Then press and hold DELAY TIME to change the delay time. The receiver displays the selected time.
