So a friend gave me one of these things 
for free because he got a new better compressor for his home studio rack. But now what I am wondering is can I set this up to work just a normal Compressor/Gate just with the amp or is it for some kind of studio rack. I don't know much in the way of rack gear as I've never owned any myself and don't have any kinda home studio beyond my protools and SM57's. So I figure some of you guys on here now way more then I do in this area.
So how do I use this compressor/Gate and set it up for the best use!
