What is the best way to set up a Variax, Helix, L2t, L2m, and microphone? I am connecting the Variax to Helix via VDI, Helix to L2t via L6 Link, L2t to L2m via L6 Link, Microphone to L2T on the 2nd channel - the problem I am having is the Microphone is only playing through the L2T not the L2M. If I unplug the Helix from the L2T the microphone will play through both speakers. How do I get everything to play through both speakers?
