Compressor 2 channels: 2 mono or 1 stereo
Sidechain on both channels to trigger the compressor on a different signal
While Jack.

UTILIZATION

Simple: while the old facade.

SOUND QUALITY

Used since the 80s. in the classic Drawmer. In my opinion, inimitable by a plug-in.
Compressor very musical, good compliance with the frequency band.
Few do little or a lot as a limiter.

OVERALL OPINION

I for a month.
I own compressors DBX, Alesis and Drawmer.
Each has its own character and that no exception to the rule.
