I received my HD621 today but will not have time until the weekend to set it up but I was wondering about the COMMS connection. I have an 800 connected to an 861 and all M digital speakers so both COMMS inputs are being used on my 861. Is it necessary to connect the HD621 to the 861 direct or can I connect it to the 800 ( as there is an unused COMMS input on it) OR can I switch the speaker COMMS that is currently connected to the 861 over to the 800 and then connect the HD621 directly into the 861 OR does it matter as all three units will communicate as long as there is a connection between the three?
Thanks in advance
Joe
