Using the Surround Processor
The Built-in surround processor provides three types of the
surround modes — JVC’s 3D-PHONIC mode, DAP (Digital
Acoustic Processor ) mode, and Dolby Pro Logic mode.
On JVC’s 3D-PHONIC Mode ———
JVC’s 3D-PHONIC mode gives you such a nearly surround
effect as it is reproduced through the Dolby Surround decoder,
which is widely used to reproduce sounds with a feeling of
movement like those experienced in movie theaters. JVC’s
3D-PHONIC mode is the result of research on sound localiza-
tion technology carried out at JVC for many years and makes
it possible to reproduce the surround sound with only two
front speakers.
On DAP Mode ——————————
The sound heard in a concert hall or club consists of direct
sound and indirect sound — early reflections and reflections
from behind. Direct sounds reach the listener directly without
any reflection. On the other hand, indirect sounds are delayed
by the distances of the ceiling and walls. These direct sounds
and indirect sounds are the most important elements of the
acoustic surround effects. The DAP mode can create these
important elements, and gives you a real “being there” feeling
by using only the front speakers.
On Dolby Pro Logic Mode ————
Dolby Pro Logic is a function devised for home use to allow
families to enjoy movies and music software bearing
* mark which includes the same encoded
surround information as found in Dolby Stereo films. Since
Dolby Pro Logic reproduces dialogue from a center speaker
independently, emphasizes the movement of sound, and gives
you a real “being there” felling.
