SPEAKER SETUP FOR THIS UNIT
SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The speakers to be used with this unit
will be mainly front speakers, rear speakers, and a center speaker. (You can omit the 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 the speakers of
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 (most important effects as well as dialogue) encoded with the Dolby Surround. The rear
and center speakers do not need to be equal in power to the front speakers. However, all the speakers should have high enough
power handling to accept the maximum output of this unit.
SPEAKER CONFIGURATION
5-Speaker Configuration
This configuration is the most effective and is the one that is
recommended. In this configuration, the center speaker is
necessary as well as the rear speakers. If the digital sound
field program is in DOLBY PRO LOGIC, ENHANCED or TV
THEATER mode 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 page 13.)
4-Speaker Configuration
The center speaker is not used in this configuration. If the
digital sound field program is in the DOLBY PRO LOGIC,
ENHANCED or TV THEATER mode, 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.
(For details, refer to page 13.)
SPEAKER PLACEMENT
The recommanded speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal
stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following.
Front: In normal position. (The position of your present
stereo speaker system.)
Rear: Behind your listening position, facing slightly inward.
Nearly six feet (approx. 1.8 m) up from the floor.
Center: Precisely between the front speakers. (To avoid
interference with TV sets, use a magnetically shielded
speaker. If, however, it is not effective, keep the
speaker away from TV sets.)
