I have several Beolink Passives in a Beolink setup. What I need to know that the manual doesn't say, is if the PowerLink socket provides the 5V switching current - I need this for a bespoke application. The manual just states it is not to be used for powerlink speakers - I think it is used if you want use it as just an amplifier and accepts the 5V switching signal, but does if it is used as a Beolink product does it give out a 5V signal. I can test with a meter but wanted to know beforehand as the units are at another house.
