Setting Up Your Speaker System
This unit has been designed to provide the best sound field
quality with a full seven-speaker system setup, using two extra
pairs of effect speakers to generate the sound field plus one center
speaker for dialog. We therefore recommend that you use a seven-
speaker setup. A four-speaker system using only one pair of effect
speakers for the sound field 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 full seven speaker system
later. In the 4 or 5 speaker system, the Digital Sound Field
Processing is still performed, but the main speakers are used for
both the main channels and the front effect channels.
Use of the Center Dialog Speaker Is Recommended
When playing back a source with the DSP programs No. 1
through No. 4, or when the Dolby Digital (AC-3) is decoded with
any DSP program used, if the source contains center-channel
signals, dialog, vocals 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
It is also possible to further expand your system with the
addition of a subwoofer and amplifier. 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.
