14 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.

Select this mode to enjoy a virtual sound field, produced from the front 2-channel speakers.
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.
Use this to enjoy video game sources.
Select this when watching monaural movies for a greater sense of expansion.
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.
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.
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.
