t 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.
