So Ive had this problem awhile but it comes and goes...but Im sick of it now. I usually have to have it cranked up to max gain or just below to get any decent signal. Also, it seems to just cut out every once in awhile. To get the signal to come back in I sometimes unplug and plug the mic back in...Ive even got the signal to come back by whacking the mic (an old mic lol) against something or screaming REALLY LOUD into it. I know that sounds crazy but its fkn true...I was hoping it was just the bad mic but its all my mics. Is it maybe my mic cable? Do I have a tube or something out or loose in my Brick? Dont know much about tubes so any help would be most appreciated. Also, I found a similar posting on SOS forums...I dont have a membership so I couldnt comment though. There didnt seem to be a clear solution. Forum - GENERAL DISCUSSIONS : Music Recording Technology THANKS!!!
