Using Advanced Sound Options

Notes:

•You must use the remote control to make these sound adjustments.

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

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.

Rear Levels

Press – REAR RIGHT LEVEL + or – REAR LEFT LEVEL + to adjust the rear speak- ers’ sound level.

Subwoofer Level

Press – SW LEVEL + to adjust the subwoofer sound level. This control works in any sound mode.

Note: 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.
