Dsp Modes - JVC RX-8020VBK Instructions Manual

I 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.
Early reflections
Direct 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.
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.
Reflections from
behind
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.

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.
