DOLBY PRO LOGIC

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)

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.

1Press 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.

2Press 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 CEN: Center speaker R: Right speaker

SUR: Surround speakers

3 Adjust the sound level of the center and the surround speakers.

While “CEN” or “SUR” is displayed, press fDOWN 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.

4Press 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.
