DYNAMIC_RANGE_COMPRESSOR

Transistorized version of vacuum-lube drawdown limiter or compressor amplifier limits dynamic range of any negative input signal without a threshold or saturation level. Output is approximately proportional to cube root of input, thus giving effective dynamic range compression. Good over audio range, yet can operate up to megacycle region if used with suitable high-frequency transistors and series inductance to varistor. Maximum input signal of 200 my produces 3 v output, corresponding to gain of 15 at maximum permissible compression.-D. E. Lancaster, Dynamic Range Compressor, EEE, 11:2, p 25.
