a "variable-mu" type compressor circuit

The WA-47jr circuit uses high quality Toshiba FET's

and the fact it is not influenced by the temperature of the environment

This solution allows to saturate only the low frequencies

Gyratec XIV-S a "variable-mu" type compressor circuitThe filter itself consist of five bands each with 11 switchable frequencies, continuous variable "Q", and individual boost bypass cut selection. The unit has an overall output level "TRIM", and a hard relay bypass serving as reference for your work. The stereo channels are linked controlled with one set of knobs, so you won't ever have to match settings of two channels. The "Q"s, filter sharpness, are rather low when boosting, but higher at cut
