I am trying to connect my GC-100 and Logitech RF/IR base station to my XANTECH connecting block. I had assumed that all I needed to do was take the output of the GC-100 and the Logi base unit to the inputs of the Xantech using the IN and GRD connections. In other words take a mono plug that an emitter would normally be attached to and connect it to the input of the xantech 795-44. It doesn't work. Any suggestions?
