Hello,
Just bought a brand new MODEL 12. Turned it on and found a problem that hopefully is unique to me and not to all Model 12s.
Does anyone have an issue with the MID knob controls creating a noise? Basically, if I adjust the MID GAIN higher or lower than 0 (zero), a noise kicks in... you need to have your MAIN or SUB outs jacked up fairly loud to hear it, but it's noticeable enough even at normal gain levels. No instruments need to be plugged in either.
The noise changes by adjusting the MID FREQUENCY knob after the GAIN is set higher or lower than in the middle. It's pretty bad the lower you go with the FREQUENCY knob. The sound completely disappears once I set my MID GAIN back to zero, which makes me think something is wrong with my mixer, or this is normal. I don't know... I updated the firmware. That's about all I can think to do.
I can set it to 400hz, for example, then sweep the gain high or low and I get what sounds like a white noise with a low cutoff filter. It's constant at whatever gain I set. It sucks and could possibly make the midrange eq unusable, since I'm typically cutting the lower mid frequencies.
