Before Operation, Delay Time Setting

Delay Time Setting

In Dolby Digital or Dolby Pro Logic II mode, it is assumed that the distance from the listener to each of the speakers is equal. If not, then setting the delay times of the center or rear speakers so that the sound will be heard simultaneously by the listener.

The interval from the speakers to the listener. If the dis- tance from the listener to each speakers is same, in the Dolby Digital and Dolby Pro Logic II mode, the delay time of each speakers is as follows.

In Dolby Digital mode

Center delay time : 0 ms (0-5 ms)

Surround delay time: 5 ms (0-15 ms)

In Dolby Pro Logic II mode

Center delay time : cannot set

Surround delay time:

PROLOGIC: 10 - 25 msec

MOVIE: 10 - 25 msec

MUSIC: 0 - 15 msec

VIRTUAL: cannot set

MATRIX: 0 - 15 msec

If the surround delay time is set in Dolby Digital mode, in the Dolby Pro Logic II mode, the delay time will be auto- matically set.

The delay time is 1 msec per 30 cm.

If the center and rear speakers are further than the front speakers from the listener, the delay time will be at min- imum.

Surround delay time setting

If the distance of DS is equal to or longer than the DF in the above figure, set the Surround Delay Time as 0ms. Otherwise, change the setting according to the below.

Ex) If the distance from front speakers to the listener is 3 m and from rear speakers from the listener is 1.5 m, in the Dolby Digital mode the surround delay time is 5 msec.

3m (DF) - 1.5m (DS) = 1.5 m (B)

1.5m (B) = 150cm / 30 cm = 5 msec

Center delay time setting (Dolby Digital mode only)

If the distance of DF is equal to the distance of DC in the left figure, set the Center Delay Time as 0ms. Otherwise, change the setting according to the table below.

Ex) If the distance from the front speakers to the listen- er is 3 m and from the center speaker to the listener is

2.4m, the center delay time is 2 msec.

3m (DF) - 2.4m (DC) = 60cm (A) 60cm (A) / 30cm = 2msec

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

Press DELAY.

1 The current surround delay time appears in the dis- play window.

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

2Use v/V to change the delay time.

3If setting is complete, press DELAY.

You can adjust the center delay time only in the Dolby Digital mode and 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.
