How do I connect a Crown CM311AE to the TA4 connector on a Shure bodypack?
Note: The Crown CM-311AE is designed for wireless use and has an in-line module that is crucial for proper operation. This module provides equalization and bipolar power for the microphone element. The CM-311AE requires 3 to 10 volts of DC bias from the transmitter. A Shure transmitter provides 5 volts of DC bias. For questions about the Crown CM-311AE, please call Crown International (phone 219-294-8000).
