JVC RX-DP20VBK manual Using the DSP Modes, Reproducing the Sound Field, Introducing the DSP Modes

Using the DSP Modes

This unit provides a variety of DSP (Digital Signal Processor) modes. The stored basic settings and adjustments performed on the Setup and Adjustment Menus (see pages 35 to 50) are applied.

•The following operations are only possible when the receiver is ready for Zone 1 operations, and are used only for the Zone 1 sources.

Reproducing the Sound Field

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.

Introducing the DSP Modes

The DSP modes include the following modes—

•DAP (Digital Acoustic Processor) modes (LARGE HALL 1, LARGE HALL 2, RECITAL HALL, OPERA HOUSE, CHURCH, LIVE CLUB, DANCE CLUB, PAVILION, LARGE THEATER, SMALL THEATER)

•ALL CH STEREO

•STEREO FILM/MONO FILM

HEADPHONE Mode

You can also enjoy the DSP effect (except All Channel Stereo mode) through the headphones.

If you press DSP when the front speakers 1 and 2 are both deactivated, HEADPHONE mode is activated without respect to the type of software played back.

The DSP and HEADPHONE indicators also light up.

To use the DSP modes, press DSP so that the DSP modes change as follows.

The DSP indicator also lights up on the display.

DAP modes

You can use the following DAP modes in order to reproduce a more acoustic sound field in your listening room.

LARGE HALL 1 : Reproduces the spatial feeling of a large

	shoebox-shaped hall designed primarily for
	classical concerts. (Its seating capacity is
	about 2000.)
LARGE HALL 2 : Reproduces the spatial feeling of a large
	vineyard-shaped hall designed primarily for
	classical concerts. (Its seating capacity is
	about 2000.)
RECITAL HALL	: Reproduces the spatial feeling of a small hall
	designed primarily for classical recitals.
	(Seating capacity is about 500.)
OPERA HOUSE	: Reproduces the spatial feeling of an opera
	house with a high ceiling and multi-level
	seating layout.
CHURCH	: Reproduces the spatial feeling of a majestic
	church with a high ceiling.
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.

LARGE THEATER : Reproduces the spatial feeling of a large theater where the seating capacity is about 600. The built-in Dolby Pro Logic II decoder is activated

for 2-channel software. (The	indicator
lights up.)

SMALL THEATER : Reproduces the spatial feeling of a small theater where the seating capacity is about 300. The built-in Dolby Pro Logic II decoder is activated

for 2-channel software. (The	indicator
lights up.)

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

•If the surround speakers are deactivated, 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.
