Setting Up Your Speaker System
This unit has been designed to provide the best sound field
quality with a five-speaker system setup, using one pair of main
speakers for main and front effect sound reproduction, one pair of
surround speakers for rear effect and surround sounds and one
center speaker for dialog. We therefore recommend that you use a
five-speaker setup. A four-speaker system excluding a center
speaker will still provide impressive ambience and effects,
however, and may be a good way to begin with this unit. You can
always upgrade to the five-speaker system later.
Use of the Center Dialog Speaker Is Recommended
When playing back a source with the Dolby Digital (AC-3)
decoded, dialog etc. are output from the center channel. Therefore,
if you want to maximize the performance of your Audio/Video
home theater system, it is recommended that you use a center
channel speaker.
If for some reason it is not practical to use a center speaker, it
is possible to enjoy movie viewing without it. Best results, however,
are obtained with the full system.
Use of a Subwoofer Expands Your Sound Field
The use of a subwoofer is effective not only for reinforcing bass
frequencies from any or all channels, but also for reproducing the
LFE (low frequency effect) sound with high fidelity when playing
back a source with the Dolby Digital (AC-3) decoded. You may wish
to choose the convenience of a Yamaha Active Servo Processing
Subwoofer System, which has its own built-in power amplifier.
