SPEAKER SETTING UP FOR THIS UNIT

SPEAKERS TO BE USED

This unit is designed to provide the best sound-field quality with 5 speaker configuration. The speakers to be used with this unit will

be mainly front speakers, rear speakers, and a center speaker. (You can delete a center speaker. Refer to the "4-Speaker

Configuration" shown below.)

The front speakers are used for the output of the main source sound and the effect sound. They will probably be your present

stereo speaker system. The rear speakers are used for the output of the effect sound. And the center speaker is used for the

output of the center sound (dialogue etc.) encoded with the Dolby Surround. The rear and center speakers do not need to be equal

with the front speakers. However, all the speakers should have high enough power handling to accept the maximum output of this

unit that will drive them.

SPEAKER CONFIGURATION

5-Speaker Configuration

This configuration is the most effective and recommended. In

this configuration, the center speaker is necessary as well as

the rear speakers. If the digital sound field program is in the

DOLBY PRO LOGIC or ENHANCED, conversations will be

output from the center speaker and the ambience will be

excellent.

Set the center mode to the "NORMAL" or "WIDE" position.

(For details, refer to the page 11.)

4-Speaker Configuration

The center speaker is not used in this configuration. If the

digital sound field program is in the DOLBY PRO LOGIC or

ENHANCED, the center sound is output from the left and the

right front speakers. However, the sound effect of other

programs can be the same as that of the 5-speaker

configuration.

Be sure to set the center mode to the "PHANTOM" position.
