Dolby Surround has been developed to reproduce the important elements of the acoustic surround at home.

To listen to the sound of video software bearing the mark

DOLBY SURROUND * which includes the same encoded surround information as found in Dolby Stereo films, the unit can provide you with Dolby Surround decoder.

There are two types of Dolby Surround — Dolby Pro Logic and Dolby 3 Stereo.

Dolby Pro Logic can be used when the front speakers and rear speakers are connected to this unit (regardless of the center speaker connection). On the other hand, Dolby 3 Stereo can be used when only the center speaker is connected without connecting the rear speakers.
