JVC RX-F31S manual Introducing the DSP modes

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.

Reflections from behind

Early reflections

Direct sounds

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.

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).

■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.
