XLR amp output noise

I'm using an Eden 300 Traveler amp. One of the older models I guess you might say. I recorded at home on a Yamaha AW4416 with no problem at all. But when I use it in church I get this humming buzzing noise. It's not the basses ( Ibanez SR506 and Fender JazzBass 24 V)I've tried switching the ground and that doesn't do. We've resorted to a Countryman direct box which is all well and fine. But I'd like to send the tone I'm getting from my amp to the system. We have a $1,000,000 yes million dollar P.A. system with Avions the whole nine yards. I don't think that's the problem. So what could possibly be the problem. Any suggestions?

When I hear the term "hum", ground loop is the first thing that comes to mind. Does the ground lift switch have any effect? Does the problem persist with different XLR cables? How high do you have your DI level cranked? Is the hum present when using either the 1/4" effects send or tuner out jacks?

Maybe I'll try some of the different outputs. I believe there's wires all over the stage and electricals are wrapped in bundles with audio. Maybe I'll try that as well. Thanks! Switching makes very little difference.

(Playing the low-odds bets here)

Few things in this world are perfect, $1,000,000 installs included. What should be an easy troubleshooting step is to take your rig up to the mixer with a tested XLR cable & try it there. For power, plug into the same power strip the mixer does. If no hum, it's their cabling or the power you plug into onstage.

If you have a million dollar install I wouldn't be worried about getting your tone from your Eden amp. I use to own one of those fender 24 jazz basses and I got rid of it because of the buzzing noise. My guess is your basses are the problem.

+1 ... troubleshooting 101. Take the head to the console, plug it in. Then to the head box. Rinse - repeat.

All the electronics have been change. Bart preamp and Nordstrands pups. There's no noise with either bass when used with the direct box.

We covered this recently on a local bass forum. Generally speaking if you've eliminated the hum from your basses (which you have), and the ground lift button on the DI's doesn't eliminate the hum, the next step is to try an isolation transformer. You can buy them pre-made but you can build you own quite easily too.
