ENGLISH

The DOLBY PRO LOGIC feature and the center and rear

speakers (standard) assure full-scale home theater sound. When

playing back laser discs or video software that have been

recorded in Dolby Surround, astonishingly realistic sound

surrounds the listener to create a new level of audio/visual

entertainment.

Independent control of the four sound channels allows the listener

to enjoy the same type of sound reproduction experienced in

movie theaters. Voices are reproduced in the front and center

sound field, while ambient sounds like cars and crowds are

reproduced on all sides of the listener for an incredibly lifelike

audio/video experience. Please read the following carefully to

“tune” the system’s output to match the characteristics of your

listening space.

Check the following:

• Before using the DOLBY PRO LOGIC, adjust the proper

balance of speaker sound levels.

• Make sure the supplied speakers are properly connected and

positioned. (See page 4 and 5)

• Make sure the TV set and video unit are properly connected.

(See page 5)

• Make sure the laser disc, video tape, etc., support

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 4 channels.

The sequencer outputs a noise signal that “travels” from channel

to channel, enabling the simple adjustment of sound level to

achieve, at the listening position, the same apparent loudness

from each channel.

Use the remote control.

Press DOLBY PRO LOGIC to select “NORMAL”.

“NORMAL” is displayed.

If “PHANTOM” or “3 STEREO” is displayed, press DOLBY

PRO LOGIC repeatedly until “NORMAL” is selected.

Press MANUAL SELECT and hold it down for

about 4 seconds until “L” flashes.

A noise signal is sent to each channel in turn in the following

sequence.

L: Left speaker R: Right speaker

SUR: Surround speakers

CEN: Center speaker

Adjust the sound level of the center and the

surround speakers.

While “CEN” or “SUR” is displayed, press f DOWN or g

UP on the remote control to adjust the volume of the center

or each surround speaker to match the level of the front

speakers.

To adjust the balance between the left and right front speakers,

see page 9. At this time, the DOLBY PRO LOGIC mode should

be canceled by pressing DOLBY PRO LOGIC until the “OFF”

is displayed.

Press MANUAL SELECT again to stop the noise

signal.

When the sequencer outputs a noise signal, a clicking sound

might be heard from the speakers due to the characteristics of

the circuit. This is not malfunction.

About the channels

The left and right front 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 MANUAL SELECT

on the remote control repeatedly until “TIME” is displayed. Then,

press f DOWN or g UP. Each time one of the buttons is

pressed, the delay time changes as shown below.

15 mS ↔ 20 mS ↔ 30 mS
