I've started biamping my system using 2 channels from the Clarinet to feed a SET amp and the other 2 channels to feet a couple of gainclone monoblocks. The problem is, when the monoblocks are connected, one channel that is feeding the SET, let's call it the right channel, either starts distorting badly or just hisses. I can then disconnect the monoblock RCA plugs, and the channel works great.
Any ideas what is wrong?
Thanks in advance!
