Sprotnik Posted March 20, 2021 Report Share Posted March 20, 2021 Hi. I´m trying to wire a sanken Cos-11 for a wisycom MTP40 with a lemo3 connector. I was following this diagram from Sanken website https://www.sanken-mic.com/en/qanda/index.cfm/11.53 that is originally for Zaxcom TRX900 transmitters but i found it in a forum here in jwsound recommended for the MTP40. I already did it, and the soldering looks ok. In the transmitter I selected "2wire+bias". if I put on the sanken, there´s some sound at very low level. it looks to me like the bias is not powering the capsule. tried to solder it again, just to be sure it was not about a bad contact... and the same. I made a similar soldering in a countryman B6 for the very same transmitter and I had no problems. I contacted to Sanken directly, but they answered that they doesn´t have any diagram for wisycom and the can only provide me the "basic wiring method" https://www.sanken-mic.com/en/qanda/index.cfm/4.19 that is not very helpful for me. I´m thinking that maybe the diagram for Sanken cos-11+ Zaxcom TRX900 is not the correct one for sanken cos-11 + MTP40 ? , or I am missing something...? I would appreciate any help thanks!

Rick Reineke Posted April 10, 2021 Report Share Posted April 10, 2021 The (two-wire) wiring diagram for a Zax, indicates the plug pin-2 is floated (not connected), the white wire is connected to Pin-1 and the plug's shell. I do not have experience with Lemos, but have terminated more than a few, TA-3, 4, 5, Hirose, and locking 3.5mm TRS plugs. Quote Link to comment Share on other sites More sharing options...
