My L1M2 just started buzzing/loud hum when I connect the B2 to the power stand. I tried switching out the speak-on cable and also tried it with another B2 unit. The problem continues. IF I disconnect the B2 with the power stand turned on, the buzzing stops. The buzzing occurs with or WITHOUT a tone match connected. The power stand firmware is 1.4.
Hi Rotnick,
I'm sorry you are getting a buzzing/loud hum when you connect the B2 to the L1 Model II Power Stand.
You've done some great troubleshooting and diagnostics.
If I read your post correctly, you get the buzz with both B2s (you can swap them and you still get the buzz), and you've also swapped the B2 cables.

It sounds like the L1 Model II Power Stand will have to be serviced.
