Guys- I have the 2 ATM73a headset mics. this has the 4 pin mini-xlr (TA-4F) connnector. I want to put on a new connector to make it compatible with my Audio-technica "Unipaks" which use the 4 pin locking. basically, I want to turn this mic into a ATM73cW. So what I need is either: 1) 2 new locking 4 pins compatible with A-T equipment 2) or an adaptor cable. Does anyone know where I can get these parts? Jon PS: To use the headsets with no A-T equip, you need the power module. To use with A-T equip, do not need the power module.
