Beosound 9000+Beolab1+Beolab2 – high-pitched squeak

[Piotr Sokol]

Hi everyone!!
I have problem with my audio set –
beosound 9000, beolab 1 and beolab 2.
After replacing the cables with mk3, the sound that appeared when changing the volume or track disappeared. But there is a high-pitched squeak. It doesn’t change its volume and stays the same all the time from tweeters.
After changing the cables, settings and type of connections between all components, I came to some observations. The squeak appears only when I connect the subwoofer (beolab2) to the system via powerlink. Even if I turn off the power but leave the powerlink, it squeaks. After unplugging the powerlink there is silence in the speakers of beolab1.
I have new mk3 cables. Beolab1 works perfect. I checked te AC power cables.

Thanks for Your suggestions and support

Piotr.

Hi everybody

I do have the same problem with a pair of Beolab 3 newly connected to a Beosound 9000 by using propper MK3-cables. They‘re individually connected to the two PL-Sockets on BS9000. Should I look on the BS9000 side or on Beolab 3?
