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.
