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 (Digital Signal Processor) 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 ST)

When one of the DSP modes is activated, the DSP indicator lights
up on the display.

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.

3D HEADPHONE mode

If you connect a pair of headphones while one of the DSP
modes is in use, the 3D HEADPHONE mode is activated
without respect to the type of software played back.
“3DHEADPHONE” appears on the display and the DSP, 3D,
and HP indicators light up.

When using the DAP mode, the sounds come out of all the
connected and activated speakers.

•

If the surround speakers are set to “NO” in the speaker
setting (see page 21),

JVC’s original 3D-PHONIC processing

(which has been developed to create the surround effect
through the front speakers only) is used.
The 3D indicator lights up on the display.

■

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 the surround speakers are set to “NO” in the speaker
setting (see page 21),

JVC’s original 3D-PHONIC processing

(which has been developed to create the surround effect
through the front speakers only) is used.
The 3D 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.

■

All Channel Stereo mode (ALL CH ST)

This mode can reproduce a larger stereo sound field using all the
connected (and activated) speakers.

This mode cannot be used if the surround speakers are set
to “NO” in the speaker setting (see page 21).
