insanely evil buzzing



This sucks, i got this cr 1604 like i was saying, and i get it out of the box, it seems to work after i buy the power cord. Plug in the headphones cuz it was kind of late, and toy around with it. It seems like its in good enough shape. The problem is i dont have any monitors at the moment due to an electrical fire in my friends garage. So i plug the bal/unbal main outputs into this old marshal cab i have here and all i get is a terrible buzzing, like 60 cycle hum on pcp or something. could it be the marshal? it dident have a problem with my phonic mm1705, and we all know thats a peice of crap?
Anyone know whats up?

:) Blasted, you plugged +4db into HI Z /Hi gain instrument level input?. Or was it a line level input?
I expect if you don't hear hum in the phones, it could be a level mismatch, toooo much gain. Try it on the line in's of someones stereo.

Sorry to hear about about your fire :( .



this probably goes without saying since you mentioned the 60hz hum by name - but make sure they're on the same ground circuit along with everything else in the loop.

not too long ago i saw the same problem arise when a signal conditioner somehow took a piece of equipment out of the loop that everything else was plugged into. and that was strange.

good luck.

Was it just the cab, or was it into an amp as well? I read somewhere that the headphone jack will work well with an amp's input, (cheap alternative to a re-amp box...) can anyone confirm this? I think Rick nailed it though, try patching it into a stereo.
