I Conceptual Description on Spatializer Operation

• Stereo normal mode

All sound are heard from between both left and right

speakers.

• Conventional surround system

Sound expands outside the speakers but the sound

position is not stable.

• Spatializer

The sound expands outside the two speakers and

the sound position is stable.

The sound come to have its expansion and depth.

And also, a sound source in the center position is

necessarily positioned in center regardless of the

spatializer effect value.

I Usage Notes

1. Do not apply 0.3 V or more to pin 12 because it relates with pin 13 (VCC pin)

2. If more than 0.3 V is applied to pin 12, the current flows to pin 13 (VCC pin) via a surge protection diode connected

to pin 12.
