Ben Turney Posted July 14, 2016 Report Share Posted July 14, 2016 This is really strange. Several years ago I had bought some universally wired COS-11D's from a dealer and then noticed that they seem to be wired out of phase with some other universally wired COS-11D's that I have from a different dealer. I noticed the phase effects when holding them close to each other and listening to them mixed. (Could this happen when the white and black wires are reversed? I can not see how they are wired because of the heat shrink tubing.) Mostly I did not use the different phased mics together on jobs so the phase issue has not been a problem. And all the mics have worked fine on older UM200a transmitters and also some SMQV's that I have. But I have just this week purchased some new LT's and an SMV. The phase-reversed COS-11D's hardly work on them -- I have to turn the transmitter gain up all the way to hear a little audio, and of course, there's too much hiss and something is clearly wrong. But my older non-phased reversed COS-11D's sound fine on these new LT's and SMV. Has something changed about the wiring to the input connector on the newest Lectrosonics transmitters? Something that is different even from SMQV's that are about 3 years old? Quote Link to comment Share on other sites More sharing options...
Eric Toline Posted July 14, 2016 Report Share Posted July 14, 2016 Universal (works on all Lectro tx) wiring for Cos 11 is for a TA5, jump pins 2 & 4, white & shield to pin 1, black to pin 3. Quote Link to comment Share on other sites More sharing options...
