Setting Up Your Speaker System
This unit has been designed to provide the best sound field quality with a full five-speaker system setup, using one extra pair of effect speakers to generate the sound field plus one center speaker for dialog. We therefore recommend that you use a five- 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 five speaker system later.
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.
