Hi, Yes, you can add the Beolab 7-1 via Powerlink as an extra spkeaer, although you will only get stereo sound through all speakers, not surround sound.  You need a Powerlink mk.3 cable like this one (this can connect to any spare socket under one of the 6000 speakers):- https://soundsheavenly.com/powerlink-8-pin-din-connection/20-266-powerlink-mk-3-compatible-8-pin-din-cable-with-4-cores-wired-low-profile-cable.html#/1-length-05m Kind regards, Steve.

Hi, Thanks Steve for your reply. I have such a Powerlinkcable (not yours) and I will try it out to use it as an extra speaker to the Beosystem 3500 or Beocenter 8500 with Beolab 6000 The Beolab 7.1 is working connecting with someting like this connecting with an Macbook to play Apple Music. https://soundsheavenly.com/line-in-connection/102-438-minijack-to-beolab-2-7-8-10-28-and-2500-powered-trigger-kit.html#/2-length-1m Beolab 7.1 is old, nice sound but so big. So I have to figure out where to place it.
