The Action is a FET compressor reminiscent of the MC77. Designed to work in standard 500 series racks.

The Action features a constant impedance 600 ohm input attenuator feeding the input transformer, just like our MC77 units. This makes the input more resistant to overload by hot signals. After the input transformer, the signal is attenuated by the same gain reduction FET as in the MC77. The attenuated signal is buffered by our class A KDJ3 opamp, which feeds the output fader. Lastly, our class AB KDJ4 output opamp drives our custom hexafilar nickel and steel output transformer. The total gain (with no attenuation) is 45dB, just like the MC77.

Attack and release times cover a broader range than the MC77, which can cause distortion... which may or may not be what you are looking for. Use at extremes with caution. The ratios are the same as the MC77, and the threshold moves up as the ratio goes up, just like the MC77.
