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.

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.
