| | Bad Capacitor?
I have been toying around with a M-Audio ProjectMix IO board that I purchased recently. After about a week of owning it, I was recording with my Red Type B microphone. It began to give me static during a vocal take, and it grew louder and louder until it was peaking the pres. If I turned off the phantom to the mic, the rushing stopped, and if I left it for a while, it would take time (2-3 minutes) to return again. The static eventually (after 30 minutes of testing it or so) turned to a rushing noise, and slowly turning the microphone from side to side produced massive low frequency booms and pops.
I sent the mic off to Red, and it was just returned to me. Red says it had a bad capacitor, and that they replaced all of the electronics.
What could have caused a bad capacitor? As the board is new, and I have used the mic previously, my gut tells me something might be askew with the board. My technical knowledge in the area of electronics is limited, however, so I don't even know if that's possible.
FWIW - When recording later with a pair of Oktava MK-012s, one of the mics started giving me some static. After A/Bing many components in the chain, I found the problem to be a faulty mic cable (or so I think). I got a new cable, and I ran into the same problem. Traded the new cable in for another, and the problem hasn't come back. Fairly odd to have two faulty cables like that. Could my board just be screwy? What do you guys think? Any input is much appreciated.
