Hello Brains Trust, I have checked the manuals for the zaxcom Deva 24 and Mix 16 but I can not find the pin configuration for the TA5 slate microphone output on the Mix 16. The Trs input for the Deva 24 is sleeve ground ring - tip +. Wiring the TA5 1 sleeve 2 to tip 3 to ring, gives us level but has a loud hum interference sound. We have also tried with no connection on pin 3 with the exact same issue. Any thoughts? Regards Matthew
