DSP Modes

DAP (Digital Acoustic Processor) 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 (see the diagram below). These indirect sounds are the most important elements of the acoustic surround effects.

The DAP mode can reproduce a realistic sound field by adding these indirect sounds.

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

HALL 1: Gives clear vocal and the feeling of a large concert hall (where the seating capacity is about 1,000).

HALL 2: Gives clear vocal and the feeling of a small concert hall (where the seating capacity is about 300).

LIVE CLUB: Gives the feeling of a live music club with a low ceiling.

DANCE CLUB: Gives a throbbing bass beat.

PAVILION: Gives the spacious feeling of a pavilion with a high ceiling.

JVC Theater Surround

In order to reproduce a more realistic sound field in your listening room, you can use JVC Theater Surround.

All Channel Stereo mode (ALL STEREO)

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

All Channel Stereo can be used when the front and surround speakers are connected to this receiver without respect to the center and/or surround back speakers connection.

THEATER 1: Reproduces the sound field of a large theater (where the seating capacity is about 1,000).

THEATER 2: Reproduces the sound field of a small theater (where the seating capacity is about 300).

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

If only the front speakers are connected or the front and center speakers are connected, JVC’s original 3D-PHONIC processing (which has been developed to create the surround effect only through the front speakers) is used.

The 3D-PHONIC indicator lights up on the display.

3D HEADPHONE Mode

This receiver creates acoustic environment through the headphones as though using 5 speakers by signal processing algorithms—3D HEADPHONE mode. The processor combines all channels except LFE channel into two encoded channels. By turning off both the SPEAKERS ON/OFF 1 and SPEAKERS ON/OFF 2 then pressing DSP, 3D HEADPHONE mode is activated without respect to the type of software played back. You can enjoy more natural sound as though you are listening to directly through the conventional stereo headphones. The DSP and HEADPHONE indicators also light up.
