DSP SURROUND
SIMULATION
• This unit is equipped with a high performance
DSP (Digital Signal Processor) which uses digital signal processing to synthetically
recreate the
sound field. One of 7 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.
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.
MONO MOVIE
Select this when watching
monaural movies for a greater sense of expansion.

3
ROCK ARENA
Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.
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.
5
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

component
of the input signals (the component
that provides the sense of expansion) processed
for
delay are output from the surround channel.
7
VIRTUAL
Select this mode to enjoy a virtual sound field, produced from the front 2-channel speakers.
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:
DIRECT, STEREO and 5CH STEREO 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 the other surround modes, the mode automatically
switches
to STEREO.
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.
