How do I connect any of the following AKG microphones to the TA4M connector on a Shure wireless bodypack?
The above AKG microphone models can be connected to any Shure bodypack transmitter with a Switchcraft TA4M input connector (shown below.) These are positive bias models.
- The resistor and capacitor should fit inside of the TA4F
- The jumper is required between Pin 3 and Pin 4 to set the correct input impedance (20kohms).
- The mating connector for the Shure wireless transmitters is a Switchcraft TA4F. This connector is available from the Shure Service Department at 800-516-2525 as part number WA330.
The connector, capacitor and resistor can be purchased from Mouser Electronics (no minimum order) at 1-800-346-6873. The parts are also available from Newark Electronics (800-463-9275). Newark identifies these parts as follows:
capacitor: Stock # 65F2327, Type 336X9010B2
resistor: Stock # 91F4531, Type NCF25J153TR
Note: There are two negative bias AKG models (C407 and C410) which require a different wiring scheme.
PIN 1 = cable shield / audio return / bias return
PIN 2 = +5V DC Bias
PIN 3 = audio input for dynamic mics or instruments
PIN 4 = 20K Ohms resistor to ground jumpered to pin 3 for condenser mics
