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).

SOURCE: Loud hum when Bose Companion 3 Series II speakers are turned on.

I had the same problem for many months. I asked a sound & video professional and he suggested I move the subwoofer away from any power source. I had the subwoofer next to my UPS. Once separated and moved all wiring away from the power supply (about 12") the low bass hum was practically gone.

SOURCE: get loud hum from both

try swapping the speakers around if the problem still persists either the speaker is faulty
the speakers plug/outlet is usually at the back of the computer you will have to open up the computer to check the lead attached to the rear of the input plug make sure the connection is good
be sure to wear an anti static earth strap before touching anything inside your computer
try cleaning your computer of dust using a fine air blower from a compressor making VERY sure that there is no MOISTURE in the air line specifically around the CPU central processing unit and your sound card dust causes static to build up in a computer causing it to overheat any many other problems
hope this helps

The Tone Match unit is not receiving power

If you are using the Bose ToneMatch cable (black cable - the connectors are round barrels with square connectors). Then this should work fine.

If it doesn't then try a different cable. You can use a network Cat-5 cable.
Note - if you are connecting to an L1® Model I or L1® classic then you need an T1 Power Supply.

L1 model 2 trim not working with tonematch

The Model II Power Stand Trim only affects the Model II Analog input (1/4" jack).

It has no effect on the signal from the T1®.

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.
