It is a WISA connection hub. Speaks to the beolabs totally wirelessly. 
Here is the link  

Hello

I've juste receive my stereo hub, to drive my beolab 18 (and 19)

I follow the instruction to pair the speaker and they are connected.

The problem is that they both play right channel and I can't find how to dispatch channel.

On beolab I can just select "wireless" but not a channel

I don't have try setup the subwoofer yet until stereo isn't ok.

So, is there an GUI (google home, ip acces to hub ...) which can allow to attribute channel on connected devices ?

For now, this wisa standard, doesn't seems to be as easy as it's said....

Thanks for feedback

With my 17s  they auto assigned left and right. Have you updated the firmware on the hub? This was a must for me

Is it also possible to hardwire the Beolabs?

For some reason I don’t like using WISA.

Yes it is. I have personally never tried it and don’t have the cables to give it a go. You can connect them using powerlink cables. The only issue is the input, they have an analogue input but the digital input needs to be from a bang and Olufsen source. 
therefore it depends on what you wish to connect them to 

Hello,

How can you do this ? where to find the update ?

Thanks
