Introducing The Dsp Modes - JVC RX-D412B Instructions Manual

About other digital signals
Linear PCM—Uncompressed digital audio data used for
DVDs, CDs, and Video CDs
DVDs support 2 channels with sampling rates of 48/96 kHz,
at quantization of 16/20/24 bits. On the other hand, CDs
and Video CDs are limited to 2 channels with 44.1 kHz at 16
bits.
• When Linear PCM signal is detected, the LINEAR PCM
indicator lights up.
Multi-channel PCM—Uncompressed multi-channel digital
audio data used for DVD-Audios
DVD-Audios support up to 5.1 channels with sampling rates
of 44.1/48/88.2/96 kHz and 2 channels with sampling rates
of 44.1/48/88.2/96/176/192 kHz, at quantization of 16/20/24
bits.
• When the Multi-channel PCM signal is detected, the
LINEAR PCM indicator lights up and "MULTI CH PCM"
appears on the display for a while.
Dual Mono
Dual Mono can be easily understood when you think of the
bilingual broadcast for TV programs (however, the Dual
Mono format is not identical with those analog formats).
This format is now adopted in Dolby Digital, DTS, and so on.
It allows two independent channels (called main channel
and sub-channel) to be recorded separately.
• You can select either channel you want to listen to (see
page 32).

Introducing the DSP modes

The sound heard in a concert hall, club, etc. 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 DSP modes can create these important elements, and
give you a real "being there" feeling.
Reflections from behind
Early reflections
The DSP modes include the following modes:
• Digital Acoustic Processor (DAP) modes—HALL1, HALL2,
LIVE CLUB, DANCE CLUB, PAVILION, THEATER1, THEATER2
• MONO FILM—Used for all types of 2-channel signals
(including Dual Mono signal)
• All Channel Stereo mode (ALL CH STEREO)
When one of the DSP modes is activated, the DSP indicator
lights up on the display.
Direct sounds
7 Digital Acoustic Processor (DAP) modes
You can use the following DAP modes in order to reproduce a
more acoustic sound field in your listening room.
HALL1 Reproduces the spatial feeling of a large
shoebox-shaped hall designed primarily for
classical concerts. (Its seating capacity is about
2000.)
HALL2 Reproduces the spatial feeling of a large
vineyard-shaped hall designed primarily for
classical concerts. (Its seating capacity is about
2000.)
LIVE CLUB Reproduces the spatial feeling of a live music
club with a low ceiling.
DANCE CLUB Reproduces the spatial feeling of a rocking
dance club.
PAVILION Reproduces the spatial feeling of an exhibition
hall with a high ceiling.
THEATER1 Reproduces the spatial feeling of a large
theater where the seating capacity is about
600.
THEATER2 Reproduces the spatial feeling of a small
theater where the seating capacity is about
300.
NOTE
When "THEATER1" or "THEATER2" is activated while playing back
2-channel analog or digital source, the built-in Dolby Pro Logic II
decoder is activated and the
When using the DAP mode, the sounds come out of all the
connected and activated speakers.
• If "SURROUND SPK" is set to "NO" in the speaker setting
(see page 30), JVC's original 3D-PHONIC processing (which
has been developed to create the surround effect through
the front speakers only) is used.
The 3D-PHONIC indicator lights up on the display.
7 MONO FILM
In order to reproduce a more acoustic sound field in your
listening room while viewing monaural sound video software
(analog and 2-channel digital signals including Dual Mono
signal), you can use this mode.
The surround effect will be added, and the sound localization
of actor's words will be improved.
This mode cannot be used for multi-channel digital
signals.
When "MONO FILM" is used, sounds come out of all the
connected (and activated) speakers.
• If "SURROUND SPK" is set to "NO" in the speaker setting
(see page 30), JVC's original 3D-PHONIC processing (which
has been developed to create the surround effect through
the front speakers only) is used.
The 3D-PHONIC indicator lights up on the display.
• If incoming signals change from 2-channel digital signal to
another digital signal type, "MONO FILM" is canceled and an
appropriate Surround mode is activated.
