I'll cut to the chase for once in my life;
Studiomaster P7 16:8:2 analogue desk, bought in 94 - never used to, but now emits very audible buzzing through the speakers, regardless of if the volume/faders are up and even when nothing's connected. When volume is up, buzzing doubles in volume if I output a further 2 soundcard outs to the desk (in addition to the other 2 going to sampler inputs).
If I connect the soundcard outputs directly to the (powered) monitors, it's crystal clear, same with the Akai etc. As the setup is at the moment, the buzzing is coming into the Akai when I sample from the soundcard outputs, even though it doesn't pass through the desk beforehand, it's a direct connection.
All desk channels are working fine, so I'm assuming it's something to do with the mixers power supply which is a 2u rackmount job with a xlr type cable connecting from that to the mixer. I've read about electrolytic capacitors needing to be replaced because of similar problems, and am wondering if that might be a solution and how/where I could get it done? Read about bad earths too, but don't really get all that stuff
Hoping I can replace the psu if it's goosed, not sure where to look though..,
Thanks, and sorry for not cutting to the chase at all
