A general handrule is, that the warmest color is right.

I'd say;
Pin 1 Red - right
Pin 2 White - left
Pin 3 Black - ground.

You need all three to transfer a stereo signal.

Thanks for your response Martin.

Does this mean the inegrated amplifier is stereo?

I assumed it was mono to have stereo with two speakers combined.

P4-1 is the audio signal that starts the autostart when you are not using PL cables.

P4-2 is the audio signal that goes to the crossover board

P4-3 is ground

Oh sorry, I forgot the channel selection is done upstream from here.

Pin 1 is for the autostart
Pin 2 is audiosignal
Pin 3 is ground

Thanks a lot!

There are two things I try to understand:

1. Does "Autostart" mean that the BeoLab 8000 speaker will switch from 'Standby' to 'On' when an audio signal is detected on P4-1?
2. Is the P4-2 signal the Left or Right channel signal that is being processed to sound one can hear? Also meaning, the P4-1 signal is only for switching, not for hearable sound?

You might notice the auto switching, has a way to aggressive (short) time constant. Watching a movie is pretty much impossible, the BL8000 goes on and off all the time. click, click, click....😁

Thanks all for responding. Happy to have gotten this knowledge from you!

One more thing. Obviously, I am going to use the P4 connector (Pins 1 to 3) for my project. So I will have to order a (3-wire) cable with connector that fits to P4.

Does any one know if this cable has a specific name/type?
(Helps me ordering the right one)

Is the P4 connector a "JST 2.0 3-pin" connector?
