This Best Audio Compressor Circuit Diagram 2-band compressor splits the audio into high and low frequencies and allows independent adjustment of each. TVo active filters drive the two halves of dual voltage
controlled amplifier/rectifier IC. Each section has a dynamic range
greater than 100 dB. Compression gain slopes are adjustable from 2 to 25
for both audio bands. iB adjusts the threshold amplitude between the
two bands. RK1 and R2/C2 control the compressor attack times (10 kfl and
2, respectively), while the 1.5- resistor in the integrator circuit
controls the release line.
