SURROUND-SOUND EFFECTS

Surround-sound

The AVC20 is equipped with three types of surround processors which provide a sense of presence and expan- sion.

4Every day, we are exposed to sounds coming from our )surroundings. Some sounds reach our ears directly from

the source, some indirectly reflected off of walls or the ceiling. Sounds of voices reach us from behind, sounds of cars reach us from the side. Sounds coming from all around us are called "surround-sounds".

In order to recreate with as much precision as possible, that special sound heard in movie theaters, speakers are placed both in front of and behind the listeners. The reason that sound from the television in our homes i s so different from the sound in movie theaters is because sound from a television only comes from in front of the viewer. With a surround system, the spatial infor- mation encoded in a film'ssound track will be repro- duced in the home listening area.

The sound from a TV equipped with a single speaker (or two speakers with stereo televisions) sounds very dif- ferent from the actual, "live" sound.

The AVC20 is equipped with three types of surround processors to recreate that sense of presence and let you enjoy surround-sound in the privacy of your own home.

Surround Processors

=DOLBY SURROUND*

Provides the optimal sound when watching recent movies, especially those encoded with the DOLBY SURROUND or DOLBY STEREO process. The front speakers provide the normal stereo effect, while the rear speakers reproduce the surround signals. This position provides excellent results when watching television programs, video soft- ware, video discs, or videotapes of stereo television broad- casts.

CONCERT SURROUND

This provides the best results when watching old movies or video recordings of concerts. The front speakers provide the normal stereo effect, while the rear speakers provide reverberation like that heard in concert halls. The reverbe- ration time can be adjusted using the CONCERT SURROUND Control.

SPATIAL SURROUND

Use this when watching live sports games to reproduce that stadium feeling.
