I have finally found a Beomaster 4500 and Beogram 4500 cd with two way communication in perfect condition. The setup is: Beomaster 4500/Beogram 4500/Beolab 4 * 2/Beolink 5000 & 7000. Original B&O Powerlink MKIII cables with 4 pins connectivity and "screen" (the metal wires surrounding the other cables).
When I use a Beolink 1000 there is no noise on the speakers when adjusting volume, changing source and so forth. However, when I use my Beolink 5000/7000 the speakers makes a noise whenever the Beomaster sends data to the two way remote controls. And that can be rather irritating whenever one is programming the Beomaster with the Beolink 7000 since there is quit a bit of communication from the Beomaster to the remote. Strangely enough, there is no noise when sending signals from the remote to the Beomaster 4500.
My local B&O dealer says that I do not need fully mounted Powerlink cables (Powerlink MK2 where all 8 pins are connected) since my Beolab 4 do not have any display.
Is there anyone who has an idea why this happens? Is it a cable problem? Has any one experienced it? Could it be that I have not put the Beomaster in the right mode? And is so, how doI change it?
