Activating the Surround Sounds
The built-in surround processor provides three groups of programs — JVC 3D-PHONIC mode, DAP (Digital
Acoustic Processor) mode, and surround modes (Dolby Surround and JVC Theater Surround).
You cannot use the DAP mode and surround mode at the same time. When you turn on the DAP mode, the surround mode is
turned off (if it has been on), and vice versa.
Notes:
The surround processor has no
effect on monaural sources.
The surround processor cannot
be used for recording.
Direct sounds
On JVC 3D PHONIC mode
JVC 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 3D-PHONIC mode is
the result of research on sound localization
technology carried out at JVC for many
years and makes it possible to reproduce the
surround sound with only two front
speakers.
On the 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 the front
speakers and rear speakers.
On surround modes
With this receiver, you can use two types
of the surround mode.
Dolby Surround
Dolby Surround has been developed to
reproduce the important elements of the
acoustic surround at home.
To watch the soundtracks of video software
bearing the mark
DOLBY SURROUND
* which
includes the same encoded surround
information as found in Dolby Stereo films,
the receiver can provide you with 2 Dolby
Surround modes (Dolby Pro Logic and
Dolby 3ch Logic).
Dolby Pro Logic: Select this mode when optional center and rear speakers are
connected.
Dolby 3ch Logic: Select this mode when a center speaker is connected without rear
speakers.
JVC Theater Surround
In order to reproduce a more realistic sound field in your listening room while playing
soundtracks of video software bearing the mark
DOLBY SURROUND
, JVC Theater Surround
has been designed to give you clear vocals and to create a real ”being there” feeling.
The sound is reproduced through the front speakers, rear speakers and center
speakers.
