!
Features
1) Volume (main volume), balance (right/left), tone (bass and treble), surround (mode and effect), BBE processor (effect)
2
can be controlled by I C-BUS.
2) Volume is VCA with low distortion rate and low noise and can restrain the step noise.
3) The reference voltage source is stable, only a few external devices are required because I/O buffer is contained, and
the package is suitable for space-saving design for SSOP-A32.
4) Sound spread can be controlled by the matrix surround and effect adjustment.
5) The built-in AGC circuit can absorb the volume difference between input sources.
6) The contained BBE processor, which reproduce an original sound, controls the effect.
