The hum goes away when the individual gains and/or master gain are turned down. It is not always present. Also, last night I switched wall plugs and found that the hum was about 95% gone - even at a higher volume, it was barely present. So I think it does have something to do with the power supply and/or grounding. It has a very nice sound and everything works on the system.

Thanks for the reference. I read through that thread before I posted. I don't have the same issues as that fellow, but there were some tips in there I could use, thanks.


Guys,

Is there anything I can do or something I can get to make sure that if I use this in a club and get a poorly grounded outlet, I can eliminate the hum?

Just picked on of these up for some small gigs. Problem is, there is a hum. As I increase volume/gain, either on the individual or master controls, on all four channels, the hum gets more pronounced. This is the model with only an on/off switch, not the dual switch. Suggestions for reducing/eliminating the hum, please, thanks. Bob V
