Beolab 6000 scratch / crack

2 replies

Where is the difference between Beolab 6000 and Beolab 4000 MK1 Speakers?

Both hang on the same preamplivier (LOEWE OLED TV), but the Beloab 6000 scratch/crack as soon as a light or blind swich is operated in the house (preamp Outputs have already been exchanged, error remains on the Beolab 6000).

Beolab 4000 works correct without any scratch, no matter on which Output connected. The Speakers are connected with B&O Cable Part.No. 6271076.

Someone has an idea would be really grateful.
