Thanks for Your insight. I had thought about the Y-split cable. But my concerns seem to be the same as Yours. I can adjust the volume on my 7-2 using my Apple Remote.
But what do You guess will happen when also connecting a 7-4? Furthermore does the 7-4 need a trigger cable for it self, or is it enough using the one for the 7-2?
Hi guys. Thanks for your input. Somehow the Playmaker showed up as an AirPlay device. I managed to get sound out of my Beolab 7-1. But as mentioned in this thread the Playmaker is not Multiroom material. The Beosound Essence MK II is far superior in that way.
