KA8507B
INTRODUCTION
20- DIP- 300A
KA8507B is a automatic gain control system that is used for dynamic
range compression and expansion. According to the companding the
signal, this can reduce the noise components. KA8507B includes
compressor, expander, pre-amp, filter amp, limiter and mute/bypath
logic.
