connecting B&O to Sonos, with TV sound through B&O?

(Oops, mis-copied the product name: “Powerlink AUX Expander”.) This is the one that “beoworld people recommend”.  Of course it’s Danish… click on the drop-down “UK/En” flag menu.  I don't own one personally to advise further; search within beoworld.org for more opinions:

The front side is shown in the web page.  The back side is shown on the cover of the manual (see link). 

(Note that the output shown is a *single* PowerLink, which connectors carry both left and right signals.  BeoLab 6000s have two connectors, so you’ll be daisy-chaining one to the other, if you aren’t running that way already, connected to your BeoSound 3000.  (The 3000 happens to have two PowerLink output ports, so you might be connected one-speaker-to-each; no biggie, just swap the cable over to serve daisy-chain, and buy a longer one if you must.)  “People say” this model is better than some, because data is is also carried down PowerLink, and when it sees data (supposedly) it switches immediately to that input.)

Thank you for this. When you say Daisy chaining what exactly do you mean? I think I have it right below.. Currently I have single wires connected to the speakers directly in to the Beosound 3000. I.e. Left speaker in to left beosound socket, and right speaker connected to right beosound speaker socket etc.

If I understood correctly, I’m going to do the following.

1. Switch set up to daisy chain one speaker to the other speaker in to the Beosound speaker socket. Question. Does it matter if the speaker cable i have left from the daisy chain goes in to the left or right socket on the Beosound?
2. Connect Powerlink adapter to Beosound 3000 via Din cable from the other speaker socket. Question.. are these ‘speaker sockets’ actually more powerlink sockets and i should refer to them that way?
3. Connect Powerlink adapter to Sonos via Din to RCA cable
4. Connect TV to Beosound 3000 Aux via Din to RCA Aux cable.

Phew, i think that’s right?

Close, but not perfect. 

In pictures: Lay a BeoLab 6000 down on its side and look at the bottom plate.  Then you’ll understand.

In words: Each speaker connector, which is a “PowerLink” (per B&O) DIN cable, carries both left and right channels.  Each speaker decides which channel it will play, with a switch R/L.  You will plug one BeoSound 3000 speaker/PowerLink connector into the Powerlink Expander on its input side, and one of your BeoLab 6000s into its output side.  Then you will plug your other BeoLab 6000 into the first BeoLab 6000.  Finally, you will plug your Sonos Port into the other connector on the input side of the PowerLink Aux Expander.

(Specific answers: #1: no, it doesn’t matter. #2: yes. #3: no, it looks like 2RCA->3.5mm #4: yes, same as you already have)

Ok! I think I’ve finally got it. Thank you for your patience.

I’m tracking;

• Connecting Beolab 6000 Speaker 1, to Beosound 6000 Speaker 2. (Din/Din)
• Connecting Beolab 6000 Speaker 2 in to Powerlink Aux Expander Output (Din/Din)
• Connecting Beosound 3000 in to Powerlink Aux Expander Input (Din/Din)
• Connecting Sonos Port in to Powerlink Aux Expander Input (via 3.5mm/2RCA).
• Connecting Sonos Beosound Aux port directly to TV (DIN/RCA).

I have a similar set up with Port as you laid out here. Works like a charm.
