ADJUSTING SPEAKER LEVEL

BALANCE

The unit is equipped with a built-in test signal generator called a noise sequencer for easy balance adjustment of all four channels. The sequencer outputs a noise signal that “travels”from channel to channel, enabling the simple adjustment of sound level to achieve the same apparent loudness, at your listening position, from each channel.

4Press the MANUAL SELECT button again to stop the noise signal.

If the surround speakers volume of the DSP is changed (see page 8), the Dolby Pro Logic surround speakers level is also changed.

About the channels

The left and right speakers create the stereo effect.

The center speaker helps achieve precise sound positioning over a broad sound field.

The rear-mounted surround speakers enhance the “depth”of the sound field.

To change the delay time

The surround speakers reproduce sounds a split second after the front speakers. The delay is initially set to 20 ms (milliseconds).

To change this standard delay time, press the MANUAL SELECT button twice or three times so that “TIME”is displayed. Then, press the UPA or DOWNY button. Each time one of the buttons is pressed, the delay time changes as shown below.

15ms - 20ms - 30ms

Select the Dolby Pro Logic mode according to your current type and placement of the speakers.

(See page 12.)

Press the MANUAL SELECT button and hold it down for about two seconds until “L TEST” appears.

A noise signal is sent to each channel in turn as follows:

DOLBY PRO LOGIC NORMAL or WIDE mode

r L TEST: (Left speaker)~TEST R: (Right speaker

SUR: (Surround speaker)+ CEN: (Center speaker)u

DOLBY PRO LOGIC PHANTOM mode

~LTEST-TESTR_SUR-1

3CH LOGIC NORMAL or WIDE mode

~LTEST-TESTR+CEN---l

Adjust the sound level of the center and (or) surround speakers.

While “CEN” or “SUR” is displayed, press the UPA or DOWNY button to adjust the volume of the center or surround speakers to match the level of the left and right speakers.

To adjust the balance between the left and right speakers, use the BALANCE control while “LTEST” or “TESTR“is displayed.

n

with the noise sequencer

The sound levels of the center and surround speakers can be adjusted during play of a laser disc or video software.

2While the “CEN or “SUR”is displayed, press the UPA or DOWNV button to adjust the volume.
