Buzz noise with new Mini Multi Card

I installed our Mini-Multi Out card in the B port to run our new Aviom in-ear system, now intermintantly there is a buzz noise coming through the whole system (Aviom and FOH). It fades in for about 10 seconds and then fades away. It does this when nobody is touching a thing. What could cause this?

Thanks,

Troy

Hi Troy

This sounds like a potential Hardware fault with your MMO module if you only get the problem when the MMO Module is fitted.

I suggest you contact your Distributor to resolve the issue:
