hi guys. Have a djm 700 mixer. All phono channels have a loud buzz/hum when faders turned up even with no input scorces are connected, only thing that's connected is the xlr outs. The lines on every channel are perfect just seems to be the phono stages. Any thoughts? Cheers.

One or more loose capacitors in the power supply would do that.

Thanks for the help guys. Mine had two bad caps on the botton board. Now the mixer is working the way it should again. :)
