DSP SURROUND SIMULATION

• The AVR-3802 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal
processing to synthetically recreate the sound field. One of seven preset surround modes can be selected
according to the program source and the parameters can be adjusted according to the conditions in the
listening room to achieve a more realistic, powerful sound. These surround modes can also be used for
program sources not recorded in Dolby Surround Pro Logic or Dolby Digital.
Surround modes and their features
Select this to achieve an atmosphere like that of a movie theater with a large screen. In this
mode, all signal sources are played in the 7.1-channel mode, including Dolby Pro Logic and Dolby
1 WIDE SCREEN
Digital 5.1-channel sources. Effects simulating the multi surround speakers of movie theaters are
added to the surround channels.
Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming
2 ROCK ARENA
from all directions.
This mode creates the sound field of a live house with a low ceiling and hard walls. This mode
3 JAZZ CLUB
gives jazz a very vivid realism.
4 VIDEO GAME Use this to enjoy video game sources.
Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals
consisting of the difference component of the input signals (the component that provides the
5 MATRIX
sense of expansion) processed for delay are output from the surround channel.
MONO MOVIE
Select this when watching monaural movies for a greater sense of expansion.

(NOTE 1)
In this mode, the signals of the front left channel are output from the left surround channel, the
signals of the front right channel are output from the right surround channel, and the same (in-
7 5CH/7CH STEREO phase) component of the left and right channels is output from the center channel. This mode
provides all speaker surround sound, but without directional steering effects, and works with any
stereo program source.
Depending on the program source being played, the effect may not be very noticeable.
In this case, try other surround modes, without worrying about their names, to create a sound field suited
to your tastes.
NOTE 1: When playing sources recorded in monaural, the sound will be one-sided if signals are only input to
one channel (left or right), so input signals to both channels. If you have a source component with only
one audio output (monophonic camcorder, etc.) obtain a "Y" adaptor cable to split the mono output
to two outputs, and connect to the L and R inputs.
NOTE:
Only the DIRECT and 5CH/7CH STEREO modes can be used when playing PCM signals with a sampling
frequency of 96 kHz (such as from DVD-Video discs that contain 24 bit, 96 kHz audio). If such signals are
input during playback in one of the other surround modes, the mode automatically switches to DIRECT.
Personal Memory Plus
This set is equipped with a personal memorize function that automatically memorizes the surround modes
and input modes selected for the input different sources. When the input source is switched, the modes set
for that source last time it was used are automatically recalled.
The surround parameters, tone control settings and playback level balance for the different output
channels are memorized for each surround mode.

NOTES:
• The surround speaker setting can also be changed with the SPEAKER button on the remote control unit.
• When "Default" is selected and the F courser button is pressed, "CINEMA EQ." and "D.COMP." are
automatically turned off, "ROOM SIZE" is set to "medium", "EFFECT LEVEL" to "10", "DELAY TIME" to
"30ms" and "LFE" to "0 dB".
• The "ROOM SIZE" expresses the expansion effect for the different surround modes in terms of the size
of the sound field, not the actual size of the listening room.
