1. Powerlink Cable is fine
2. Source is fine - AUX input from BS4000

Hi
Does the hummm stop after a while?

Maybe a transformer problem?

I'm an automotive audio and acoustic engineer. I design loudspeakers and full sound systems for new automobiles. I also dabble with studio, consumer and pro audio projects from time to time.
Could definately sound like a problem in the power supply.
The humm is constant - more audible with no audio signal and power on.
I guess while playing music the hummmm is supressed. Is it a simple fix to replace the power unit - the transformer i guess
If the humm is constant please try the following:
- Test the same configuration with all lights and other electric things switched off (Most humm's start from dimmed lights)
- Change the power cord to another outlet (the same as your music system or the bl4000 without the humm)
- Physically exchange the two bl4000 but keep all the existing cables (just to be shure you really have a problem in one of your beolabs)
Good luck
David
