Basic Operation

This unit is equipped with a high performance DSP (Digital Signal Processor) which uses digital signal processing to svntheticallv

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.

Basic Operation

The front left channel signals are output to the surround and surround back left channels, the front right

1 channel signals are output to the surround and surround back right channels, and the in-phase component

of the left and right channels is output to the center channel. Use this mode to enjoy stereo sound.

2 Select this when watching monaural movies for a greater sense of expansion.

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

averv vivid realism.

5 Use this to enjov video game sources.

Select this to emphasize the sense of expansion for music sources recorded in stereo. Signals consisting

of the component difference of the input signals (the component that provides the sense of expansion)

_recessed for delav are output from the surround channel.

Select this mode to enjov a virtual sound field, produced from the front 2-channel speakers or headphones.

÷ Depending on the program source being piaved, the effect mav not be verv noticeable.

In this case, try other surround modes, without werrving about their names, to create a sound field suited to your tastes.

NOTE: When plaving 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 eniv one audio output (monophonic camcorder, etc.)

obtain a "Y" adapter 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 different sources. When the input source is switched, the modes set for that source last time it was used are automaticallv

recalled.

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

each surround mode.
