well today i was loading in my amps in a new rackcase and did something stupid by mistake. when i conected all the cables at the back i... ... :scowl: went from preamp out into speaker out on the poweramp. and conected my cabs to poweramp input. when i didn´t get any sound, i disconected one of the speakercables and put it into the "preamp" (into speakerout on my SWR220, i use it as a pre only). i heard a screetching noice and turned it off. then i noticed what i had done. after i had put everything back the right way i started everything up again. well, i get sound out of it but at a really low volume(with master at max). the thing is that it´s the same with the SWR as with the poweramp. all the fuses are ok so i wonder what has really happened. my bandmate did something similar some weeks ago with his keyboardrig, but there was no problem after that. does someone has the ability to tell me if i´ve really fried something?
