Audio Compressor Circuit with SSM2165

A very simple audio compressor built with SSM2165 IC. There is no much explication about this compressor circuit schematic, just pay attention at capacitors voltage. The C8 value depends of your desired frequency amplification. Mount 7805 on a heatsink if you use higher voltages.

Audio compressor circuit components

R1 = R3 = 50K potentiometer
R2 = 25K
C1 = C3 = 100nF
C2 = C4 =C7 = 10uF
C5 = 100uF
C6 = 470uF
C8 = 2.2uF … 100uF
IC = SSM2165
