Hello, i have hooked up my beosystem 4 with 2 beolab 8000 and have tried to hook up a beolab 7-2 to the system through PL6 and other PL outputs. But every switch in the menu on the beosystem 4 gives three very loud almost painfull sounds out of the beolab 7-2.
Does anybody know what is the explanation for this?
