I'm doing a little experiment with live-streaming video from a moving car. I'm looking at using this microphone pin out diagram for the T4F connector[/DLMURL] from shure That diagram shows the following: Pin1: shield Pin2: bias (+5Vdc) Pin3: audio Pin4: Bias return From my research, I've found that the three conductors on TRS connectors are for positive, negative, and drain. What I don't know is how those three would match up to the T4F connector's bias (+5Vdc), audio, and bias return. How can I make an appropriate connection given the differences between the number of conductors on T4F versus TRS connectors? There is no place to solder the shield wire on a TRS connector, right? Would the shield wire just not be connected on the TRS end? Is there a better way I haven't considered? Thank you.
