I'm experiencing a static/crackle noise on channel 3 of my 16.4.2 studiolive. It appears to only be at start up for about 5 mins. After the board warms up, it goes away? Advice as to the cause?
Doesn't matter if there is anything plugged into the channel or not. It also doesn't matter if the board is hooked to a PC. Whenever it is powered on, you can see a signal coming through channel 3 on the meter bridge... If I send channel 3 to the mains during this, you can hear an audible scratchiness/crackle noise coming through the speakers. After about 5 mins it goes away and works fine. I'm worried this channel will die all together or become permanently noisy. Any information is greatly appreciated!
