Setting Delays

In Dolby Digital and Dolby Pro Logic mode, it is assumed that the distance from the listener to each of the five speakers is equal. If your center and rear speakers are closer than the front speakers, you can set delays so that sound from these speakers will be heard simultaneously at your primary listening position.

In Dolby Digital mode

Center delay time : 0ms

Rear delay time: 5ms

In Dolby Pro Logic mode

Center delay time : cannot be set

Rear delay time : 0-15ms

If the rear delay time is set in Dolby Digital mode, the delay time will be automatically set in Dolby Pro Logic mode .

The delay time is approximately 1 msec per foot.

If the center and rear speakers are further than the front speakers from the listener, the delay time should be set to the minimum.

Surround delay time setting

If the distance from your rear speakers to the listener is the same or greater than your front speakers, set the Surround Delay Time to 0ms. Otherwise, change the setting according to the calculation below.

SL SR

For example, if the distance from the front speakers to the listener is 10 feet and from the rear speakers to the listener is 5 feet, the rear delay time would be 5 msec. 10 feet - 5 feet = 5 feet, or 5msec

In Dolby Pro Logic II (Surround delay time): PROLOGIC: 10 - 25msec

MOVIE: 10 - 25msec

MUSIC: 0 - 15msec

VIRTUAL: cannot be set

MATRIX: 0 - 15msec

Center delay time setting (Dolby Digital mode only)

If the distance from your center speaker to the listener is the same or greater than your front speakers, set the Center Delay Time to 0ms. Otherwise, change the set- ting according to the calculation below.

For example, if the distance from the front speakers to the listener is 10 feet and from the center speaker to the listener is 8 feet, the center delay time is 2msec. 10 feet - 8 feet = 2 feet, or 2msec

Setting the delay time in the Dolby Digital and Dolby Pro Logic II mode

1 Press DELAY.

The current surround delay time appears on the front panel display.

You can select center delay time by pressing b/B in the Dolby Digital mode only.

2 Press v/V to change the delay time.

3 If setting is complete, press DELAY.

otes

You can adjust the center delay time only in the Dolby Digital mode when its delay time appears.

Center Width (MUSIC mode of Dolby Pro Logic II only)

This control allows center-channel sounds to be posi- tioned between the center speaker and the left/right speakers over a range of eight steps. Step “3” uses a combination of all three front speakers to give the best vocal imaging and most seamless soundstage presen- tation, and is recommended for most recordings. Step “0” places all center sound in the center speaker. Step “7” places all center sound equally in the left/right speakers, just as in conventional stereo.

DIMENSE (MUSIC mode of Dolby Pro Logic II only)

This control allows the user to gradually adjust the sound field either towards the front or the rear. This can be useful to help achieve the desired balance from all the speakers with certain recordings that may contain either too much or too little spatial effect. Step “0” is the recommended setting, which has no effect on the sound. Steps 1, 2, and 3 gradually move the sound for- ward, and steps -1, -2, and -3 move the sound towards the surrounds.

PANORAMA (MUSIC mode of Dolby Pro Logic II only)

This control extends the front stereo image to include the surround speakers for an exciting “wraparound” effect with side-wall imaging. It is particularly effective for recordings which have strong left- or right-channel elements in the mix, as these are detected and accen- tuated by the Panorama process.
