Surround Mode Control, Dolby PRO Logic, Test Tone

DOLBY 3 STEREO : Choose this setting to play back movies and music (especially Laser Discs, video cassettes and TV broadcasts with DOLBY SURROUND sound) when not using the rear speakers. You get a clear perception of the position and direction of the sound. DOLBY 3 STEREO combines the front and rear signals so that you can enjoy a regenerated sound field which has comparatively more lively presence and a more expansive feeling from the three front channels (front left, front right and center speakers) than that of ordinary stereo regeneration.

THEATER : Use this when watching movie sources that have a stereo soundtrack to enjoy the effect of being in a movie theater.

HALL : Hall mode works best for recorded concerts and other music programs. In this mode, the front speakers provide a normal stereo effect while the rear speakers provide a reverberated sound. This reverberation helps to simulate the sound you might hear at a live concert.

STADIUM : The "stadium" effect creates efficient, reverberated sounds in order to obtain an expansive sound field. For music sources like a rock concert, you will feel as if you were actually at the live concert and seated very close to the stage. For sports programs, such as a baseball game, you can enjoy a powerful sound, thus obtaining the true stadium effect.

OFF : Turns off the center and rear speakers for normal stereo operation.

Note : Dolby Pro Logic, Dolby 3 Stereo, Theater, Hall and Stadium will not work properly if the signal passes through a graphic equalizer. Please refer to your equalizer operating instructions for guidance on switching off (or defeating) the equalizer.
