Hi all, New to this forum but hoping someone maybe able to help. I recently purchased a M-320b series console for a really decent price, it appears to be fairly well looked after and no noticeable neglect problems. I am now experiencing a rather annoying issue though, I've now tracked drums via the desk on three separate occasions (8 channels used) and what I am finding is the desk is sending very loud pops/clicks to my interface in certain sections of the drum tracks (not always the same place though). The obvious cause would be that I am driving the desk to hard but there are a couple of factors that make me think otherwise so, no overload lights illuminate at any point, the level being recorded via my interface (which is set to line level) is VERY conservative, when trying to deliberately overload a channel to troubleshoot this issue I cannot recreate it and finally if I were really pushing the desk too hard I would expect to hear a fair amount saturation, all signals seem very clean. Signal routing is as follows. microphone>XLR>M320b input>direct out via 1/4" jack>interface input (UR824)>DAW https://drive.google.com/file/d/1O5eQsTeqQrpNnLR0yMwGvM2cMNrczPs7/view?usp=sharing I've linked a picture of the waveform to help explain better, it sounds very much like a click sound and makes the transient completely unusable. Any thoughts help very much appreciated!
