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.
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.

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 
 indicator lights up.
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.
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).
