11DSP SURROUND SIMULATION

The AVR-2803/983 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, Dolby Digital or DTS.

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.

 

 

 

3

MONO MOVIE

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

(NOTE 1)

 

 

 

 

 

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

MATRIX

component of the input signals (the component that provides the sense of expansion) processed for delay are output from the

 

 

surround channel.

 

 

 

6

VIRTUAL

Select this mode to enjoy a virtual sound field, produced from the front 2-channel speakers.

 

 

 

 

 

The front left channel signals are output to the surround and surround back signal left channels, the front right channel signals are

5CH/7CH STEREO

output to the surround and surround back signal right channels, and the in-phase component of the left and right channels is output

 

 

to the center channel. Use this mode to enjoy stereo sound.

 

 

 

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.

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.
