|Pin 1||Shield (ground)||Says by itself...|
|Pin 2||Bias (+5Vdc)|
|Pin 3||Audio +|
|Pin 4||20 k Ohm resistor to ground||(Link to pin 3 when connecting to condenser microphones. Instrument input - leave unconnected)|
These are for Shure beltpacks only as each manufacturer has it's own pinout standards for ta4 connectors. JTS, Carvin Wireless and AMX beltpacks also have the same pinout.
Pin 2 needs to be linked to pin 3 via a 2k2 resistor for Da-Cappo Condenser microphone.
Pin 2 needs to be linked to pin 3 via a 8.2k resistor for Sennheiser HSP 4.
NB: Non-condenser microphones (That does not require Phantom Power) are to be considered as Instruments and -must- be linked -Only- to pin 1 (Ground) and 3 (Audio +); even if some of these non condenser microphones may have 3 wires to connect.
