Powerlink inputs of Beolabs are unbalanced line level. But you can connect a balanced signal. Just solder a bridge between 1 - 3 (gnd / sig-) in the XLR plug and make an  XLR - DIN adapter . If you don`t want that, because all the signal chain will become unbalanced, connect a balanced-unbalanced converter (XLR - RCA) between the sub out and the BL3 Powerlink in. In both cases you will need  5V to power up the BL3. More information on Beotech site. Hope this helps.

Powerlink is not balanced (unlike Masterlink) and has a 1Vrms max. level. I would just use the RCA unbalanced outputs from your sub as line in the the BL3's. Over a short cable run such as near field monitoring it shouldn't make any noticable difference.

I looked on the internet and couldn't find any data on the output signal levels of you sub, be careful when setting up as "pro" gear  normally runs at higher signal levels than consumer equipment, so be sure to have everything turned down at the start.

Hello Simsim and welcome back to Beoworld!

Powerlink signal is not balanced, only a line output. (For more details you could have a look at Beotech).
I use powerlink to XLR cable in the opposite way as you ie from powerlink sokets of a Beocenter 9500 to XLR socket of an amplified B&O Studio monitor, but this is exactly the same thing.
Here is the diagram of my Xlr to Powerlink cables. Their length is approx 15 meters and the sound is perfect, no hum, no distortion! 🤒

I'm not sure about the shorting of pins 1 & 3, it'll be fine when wiring an unbalanced signal into a balanced input, but in this case you are suggesting shorting a -ve output to ground - this may be OK if the output is transformer coupled but that may not be the case and you could feasibly damage your device if you are unaware of it's output circuit configuration!

If you are going to make a modified lead I would suggest using pins 1&2 of the XLR as your two wire connection and not short anything to ground.

Run the Multiface on it's -10dB setting (in the FireFace settings app). I would also always add an analogue volume control between the interface and the speakers.

Out of interest, how do you find the Sub10? I've been toying with the idea of adding a sub to go with my Adam A7s, although I've heard very few subwoofers which I'd consider to be 'unobtrusive'. I've not auditioned any Adam subs yet...
