11 DSP SURROUND SIMULATION

• The AVR-2802 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal

processing to synthetically recreate the sound field. One of six 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 and DTS surround.

Surround modes and their features

1

ROCK ARENA

Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming

from all directions.

 

 

 

 

 

2

JAZZ CLUB

This mode creates the sound field of a live house with a low ceiling and hard walls. This mode

gives jazz a very vivid realism.

 

 

 

 

 

 

 

Use this to enjoy video game sources.

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-

provides all speaker surround sound, but without directional steering effects, and works with any

 

 

stereo program source.

MONO MOVIE

Select this when watching monaural movies for a greater sense of expansion.

(NOTE 1)

 

 

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 mode 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:

•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.
