DOLBY SURROUND

Using the Surround Processor

The built-in surround processor provides three types of surround programs — Dolby Pro Logic, Dolby 3-

Channel Logic, and JVC’s Hall Surround.

What is surround?

The sound heard in a concert hall or a movie theater consists of direct sound and indirect sound: early reflections and reflections from behind. The reflected sounds are always delayed by the distances of the ceiling and walls from the listener. These reflections are some of the most important elements of the acoustic surround.

On JVC’s Hall Surround

In order to reproduce a more realistic sound field in your listening room while playing an ordinary stereo source, JVC’s Hall Surround has been designed to give you clear vocals and to create the feeling of a concert hall. The sound is reproduced through the front speakers and rear speakers.

On Dolby Surround

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

To watch the soundtracks of video software bearing the mark * which includes the same encoded surround

information as found in Dolby Stereo films, the receiver can provide you with 2 Dolby Surround programs (Dolby Pro Logic and Dolby 3ch Logic).

Dolby Pro Logic: Select this mode when the optional rear speakers are connected (as well as a center speaker).

Dolby 3ch Logic: Select this mode when a center speaker is connected without rear speakers.

Notes:

•The surround processor has no effect on monaural sources.
