I just picked up a Peavey Chorus 212 amp. I noticed that there are what looks like two effects loops on the back.

I have a ART SGX2000 Express Preamp that I want to use. Should I put it between the guitar and the amp or run it through the effects loop. And if through the effects loop, which inputs/outputs should I use?

There are Power Amp In 2, Preamp Out/Mix 2, Power Amp In 1, Power Amp Out/Mix 2 on the back and I don't have any idea which input/output combination to use. I have never had an amp with more than one loop before. I am truly nonplussed by this.

Any help?
