Hi thorne,

Please can you confirm which equipment the speakers are connected to and whether they have separate cables back to the equipment, or if they are daisy-chained together?

Do both speakers still play music correctly?

Do they hum when the equipment is powered on, powered off but still connected, or both situations please?

We can then help you to locate the cause and resolve the issue.

Kind regards, Steve.

Thanks, Steve

 

6000s are daisy-chained. Only hum when playing something. Completely silent in stand by mode.  Sound is perfect through 6000s apart from hum

 

set up is

 

6000s to rear, 18s in front, Beolab 2 subwoofer. Connected to Beovision 11, Beosound 9000 and ATV

 

hope this helps

Hi thorne,

Could be a cable fault on the cable running from the TV to the first speaker.  Do you have another RJ45 to Powerlink cable that you can try in its place to see if this resolves the fault?

Kind regards, Steve

Thanks.  I don’t have a spare, but i’ll check for any loose connections in the first instance, then take it from there
