You read the instruction manual, that was probably your first mistake!
If you use masterlink you must use the ir eye.
Alternatively, If you use a Mk2 powerlink between the 3000 and the passive instead, you dont need the ir eye and the powerlink will switch the passive on and sound will come from your passive speakers. Plug the other end of the powerlink into one of the powerlink sockets on the 3000.
Now either daisy chain the 6000's from the other powerlink socket on the 3000 or get a powerlink splitter so both speakers can use the same socket.
Leave the beogram in the aux socket
