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.

Surround modes and their features

		In this mode, the signals of the front left channel are output from the left surround channel, the signals of the front
1	5CH STEREO	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.
2	MONO MOVIE	Select this when watching monaural movies for a greater sense of expansion.
	(NOTE 1)
3	ROCK ARENA	Use this mode to achieve the feeling of a live concert in an arena with reflected sounds coming from all directions.
4	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.
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
6	MATRIX	difference 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:

Only the 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 one of the other surround modes, the mode automatically switches to STEREO.

If the DTS signals are input during playback in VIRTUAL surround mode, 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.

The surround parameters, tone control settings and playback level balance for the different output channels are memorized for each surround mode.
