Noise when i
Mixer uses balanced outputs, this unit does not... Also ground loops can be a problem. Make sure this and the mixer are BOTH powered from the same receptacle. The next problem is that the level of the mixer is MUCH too high for an amp designed to recieve guitar signals if you are sending a mixer into this. It is NOT clear how you are connecting this to a mixer... IF you happen to be trying to send signals from this to a mixer, either use a mic OR use a Direct Input box. You should tell us exactly how you are connecting this to the mixer since there are MANY ways, and most do not make sense.

Marshall amp troubleshooting
Does anything happen while you turn the knobs on the amp?
I had a similar problem with a yamaha amp. It turned out a couple of knobs went bad. Soldered new pots and it works fine for me now.
