DSP SURROUND SIMULATION
• The AVR-3300 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.
Surround modes and their features
1
MATRIX
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 sense of expansion) processed for
delay are output from the surround channel.
2
ROCK ARENA Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.
3
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.
4
VIDEO GAME Use this to enjoy video game sources.
5
MONO MOVIE
(NOTE 1)
Select this when watching monaural movies for a greater sense of expansion.
6
5CH STEREO
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-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 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
The AVR-3300 is equipped with a function called Personal Memory Plus which automatically stores the surround mode and level settings
selected for the different input programs in the memory. The mode stored in the memory the last time the input program source was used is
called out automatically when that program source is selected.
