This unit will only do 10:1...
than kindly recieve my apolagize, though a 10:1 ratio is more of a limiter in my opinion. Imagine that for every 10dbs it gets on the input of the comp above the threshold it will have a 9 db of gain reduction. So if you hit the comp with -10 db and the thershold is set to -20 the output it will be like -19db on the output before gain make-up
