How do I connect an AKG C410/B or C407/B to a Shure bodypack?

FAQ #312 Updated August 04, 2017


How do I connect any of the following AKG microphones to the TA4M connector on a Shure wireless bodypack?

C401 C409 C417/B
C401/B C409/B C418
C402 C410/B C418/B
C402/B CK410 C419
C406 C411 C419/B
C406/B C411/B C420
C407/B C416 C420/B
C408 C416/B
C408/B C417


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
