I've been looking at the Powerlink wiring connections on BeoTech page and I have a question.

Given the diagram below, what is the difference between 1 - Power up and 4 - Speaker on signals?

I always thought of of pin 4 logic as "~MUTE", i.e. the opposite of the state of the mute-relay inside older Beolab speakers.  Pin 1 comes on when the zone is active so the speakers power up.  Pin 4 comes on when the speaker is to play, and goes off when the Mute button on the remote or the control panel is pressed.  This was changed for newer speakers so that only pin 4 is used for control nowadays, so a trigger & a timer inside the speaker control power on/off.  If you search the Archive forums for "Powerlink Pin 4" surely you will find more detail as it may relate to the specific speakers you are using.

Hi trackbeo, thanks for your reply. I did some reading on the archivedforum2 and found some useful information.

I'm trying to connect my non-B&O streamer to Almando Powerlink switch and the input expects a trigger signal on pin 4 to activate the input.

I have a Beolink Passive with a triggered powerlink cable which I was hoping to use to connect the streamer to the Almando switch. But the Passive trigger signal in that cable is wired to Power Up - Pin 1 and Dataground - Pin 7. Forgot to check, if Pin 7 is shorted to Pin 2 in that specific trigger cable.
