DSP SURROUND SIMULATION
• The AVR-5700 is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to synthetically
recreate the sound field. One of eight 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 AC-3.
Surround modes and their features
SUPER STADIUM
Select this when watching baseball or soccer programs to achieve a sound as if you were actually at the stadium. This mode
provides the longest reverberation signals.
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
CLASSIC CONCERT Select this for the sound of a concert hall rich in reverberations.
MONO MOVIE
(NOTE 1)
Select this when watching monaural movies for a greater sense of expansion.
4
5
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.
6
WIDE SCREEN
Select this to create the sense that you are watching the program source on a larger screen and in a place with more reflected
sound. This mode provides stronger reverberations for Dolby Digital and Dolby Pro Logic, and for DTS.

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-5700 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.
