Sennheiser CM1 Microphone Input Cable for EW Bodypack Transmitters

Female XLR to locking EW adapter cable for connecting wired microphones to Evolution Wireless bodypacks

The Sennheiser CM1 is an adapter cable with a female XLR connector on the input end and a 3.5mm threaded locking EW connector on the output end, designed to connect wired microphones and audio sources with XLR output to Sennheiser Evolution Wireless bodypack transmitters. This cable converts any standard XLR microphone into a wireless source by routing its signal through an EW bodypack transmitter.

The CM1 is commonly used when talent needs to use a specific wired microphone that is not available in a wireless version, or when a production already owns a preferred microphone and wants to make it wireless without purchasing a dedicated wireless microphone system. The locking EW connector secures the cable to the bodypack to prevent accidental disconnection during use.

Frequently Asked Questions

Does the CM1 provide phantom power to the microphone?

No. EW bodypacks provide a small bias voltage suitable for Sennheiser lavalier microphones, but they do not provide 48V phantom power. The CM1 should be used with dynamic microphones or externally powered condenser microphones.

What is the difference between the CM1 and CL100?

The CM1 is an input cable (female XLR to EW) for feeding audio into a bodypack transmitter. The CL100 is an output cable (male XLR from EW) for taking audio out of a receiver. They serve opposite directions in the signal chain.
