FEATURES
Dolby Pro Logic Surround
This unit employs a Dolby Pro Logic Surround decoder similar
to professional Dolby Stereo decoders used in many movie
theaters. By using the Dolby Pro Logic Surround decoder,
you can experience the dramatic realism and impact of Dolby
Surround movie theater sound in your own home. Dolby Pro
Logic employs a four channel five speaker system. The Pro
Logic Surround system divides the input signal into four
levels: the left and right main channels, the center channel
(used for dialog), and the rear surround sound channels
(used for sound effects, background noise, and other ambient
noises). The center channel allows listeners seated in even
less-than-ideal positions to hear the dialog originating from
the action on the screen while experiencing good stereo
imaging. Dolby Surround is encoded on the sound track of pre-
recorded video tapes, laser discs, and some TV/cable
broadcasts. When you play a source encoded with Dolby
Surround on this unit, the Dolby Pro Logic Surround decoder
decodes the signal and distributes the surround-sound
effects.
In addition, this unit features a built-in automatic input balance
control. This always assures you the best performance
without manual adjustment.
