About This Listing
The Purple Audio Action 500-Series FET Compressor 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 Purple Audio's 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, Purple's class AB KDJ4 output opamp drives their 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.
Stereo linking is accomplished by cross connecting pins 3 & 6 on the edge connector. On the Purple Sweet Ten, there is a second output 1/4″ that can be used to link two Actions. The link is accomplished using a TRS to TRS cable with tip on one TRS connecting to RING on the other TRS and vice versa. Plug in the cable, flip the front panel switches and you are linked. Non-Purple racks do not have an easy way to connect pins 3 and 6, and will need modification to link two Action units.

Product Overview
The Purple Audio Action is a 500 Series compressor / limiter module based on the acclaimed Purple Audio MC77, the company's own spin of the 1176LN bottle. Featuring the same FET gain reduction circuit as the MC77, the Action actually has a wider range of attack and release times, even allowing you to get some reverse compression effects with the slowest attack and fastest release settings. Just like a great 1176 or the MC77, the Action is amazing on bass guitars, vocals, and snare drums to shape the sound and hammer down the dynamic range.
