12SPEAKER SETUPThis unit is designed to provide the best sound-field quality witha 5-speaker configuration, using main speakers, rear speakersand a center speaker.The main speakers are used for the main source sound plusthe effect sounds. They will probably be the speakers fromyour present stereo system. The rear speakers are used forthe effect and surround sounds, and the center speaker is forthe center sounds (dialog, vocals, etc.). If for some reason it isnot practical to use a center speaker, you can do without it.Best results, however, are obtained with the full system.The main speakers should be high performance models andhave enough power handling capacity to accept the maximumoutput of your audio system.Other speakers do not have to be equal to the main speakers.For precise sound localization, however, it is ideal to use highperformance models that can reproduce sounds in the fullrange for the center speaker and the rear speakers.5-Speaker ConfigurationThis configuration is the most effective and recommended one.When playing back a source using the DSP program,DOLBY PRO LOGIC/DOLBY DIGITAL, DOLBY PRO LOGICENHANCED/DOLBY DIGITAL ENHANCED, 70 mm MOVIETHEATER/DIGITAL MOVIE THEATER, MONO MOVIE or TVSPORTS, or when playing back a source which containscenter-channel signals (dialog, vocals, etc.) using any DSPprogram with the Dolby Digital decoded, conversations will beoutput from the center speaker and the ambience will beexcellent.Note: Set the CNTR (CENTER SPEAKER) mode to the“LARGE” or “SMALL” position. (For details, seepage 22.)SPEAKER CONFIGURATIONUse of a subwoofer expands your sound fieldIt is also possible to further expand your system with theaddition of a subwoofer and amplifier. The use of a subwooferis effective not only for reinforcing bass frequencies from any orall channels, but also for reproducing the LFE (low frequencyeffect) sound with high fidelity when playing back a source withthe Dolby Digital decoded. You may wish to choose theconvenience of a YAMAHA Active Servo Processing SubwooferSystem, which has its own built-in power amplifier.4-Speaker ConfigurationThe center speaker is not used in this configuration. Whenplaying back a source using the DSP program, DOLBY PROLOGIC/DOLBY DIGITAL, DOLBY PRO LOGIC ENHANCED/DOLBY DIGITAL ENHANCED, 70 mm MOVIE THEATER/DIGITAL MOVIE THEATER, MONO MOVIE or TV SPORTS, orwhen playing back a source which contains center-channelsignals (dialog, vocals, etc.) using any DSP program with theDolby Digital decoded, the center sound is output from the leftand the right main speakers. However, the sound effect ofother programs will be the same as that of the 5-speakerconfiguration.Note: Be sure to set the CNTR (CENTER SPEAKER) mode tothe “NONE” position.
