HERE CAN YOU FIND A SCHEMATIC OF A COMPRESSOR LIMITER 03 OF 07.
AUDIO COMPRESSOR LIMITER:
A very simple Audio Compressor Limiter built with the SSM2165 IC.
There is no much explication about this compressor circuit schematic, just pay attention at capacitors voltage.
The C 8 value depends of your desired frequency amplification.
Mount the 7805 always on a Heat Sink if you use a higher voltages.
