Check cables first, then make sure everything is plugged into the same power ground. Hum is always caused by bad grounds or bad cables. Otherwise you have an internal component failure and without more information Im not sure which one it could be.

This sounds like a ground loop.
Make sure that everything in your signal chain (mixer and anything that plugs into the mixer, and the L1®) are all plugged into the same power source (power bar).

Just bought a ProFX8 mixer to connect to my Bose L1 PA system, but as soon as I connect the outputs to the Bose inputs and raise the master fader there is a "ground hum" even without anything...


Make sure you are using BALANCED audio interconnect cables AND that the speakers and the mixer are powered from the SAME receptacle... Yes, this means running extension cords. It is a ground loop problem. You should be using XLR or TRS cables BALANCED cables from the mixer to the basss unit of the L1 system. The bass unit and the mixer MUST be powered from the same receptacle to avoid ground loops and hum.

Make sure you are using BALANCED interconnection cables to the speakers, either XLR or TRS connections. ALSO make sure all interconnected equipment such as the speakers AND the mixer are powered from the SAME receptacle at the venue... yes you have to run extension cords... the pro's do it so they don't have hum and other noise and don't damage their equipment.

you can just piggyback the mixers - take the outputs from the mackie mixer (assuming it is NOT a powered mixer) ... those should be line level outputs - send them into a line level input on the digi 002 and then set that channel on the digi 002 and once set, just leave it, and control the mackie channels individually ... should work fine ...
