## Long description

Sennheiser CMB 01 CTRL is a compact controller accessory for compatible Sennheiser wireless microphone systems. It connects to a transmitter via a 3.5 mm jack and provides remote control functions and a hook-switch interface to operate transmitter features from a distance. Designed for live sound, broadcast and event environments, the controller helps streamline onstage adjustments and reduces the need to access each transmitter directly.
Advantages
The controller offers a straightforward wired connection with a 3.5 mm jack and integrated hook-switch functionality that enables hands-free or remote operation of transmitter functions. Its compact form factor and simple interface make it easy to mount or tuck into stage setups. The accessory is compatible with matching Sennheiser transmitters, providing reliable control without altering the transmitter’s firmware or main controls.
Suitable for
Live music and stage performances where quick transmitter adjustments are needed
Broadcast studios and ENG situations requiring remote mute/unmute or control
Corporate events and conferences with multiple wireless transmitters
Theatre and installations where discreet control of a transmitter is required
Key specifications
Connection type: 3.5 mm jack wired interface
Functionality: hook-switch and remote control signals for compatible transmitters
Form factor: compact inline controller suitable for mounting or discreet placement
Cable: adapter cable designed to interface between microphone/transmitter and control input
How to use
Connect the adapter cable’s 3.5 mm plug to the compatible transmitter input and route the cable to the preferred control location. Use the hook-switch function to perform mute, unmute or other remote actions supported by the connected transmitter according to that transmitter’s user manual. Ensure connectors are fully seated and secured to avoid accidental disconnection during use. Verify operation before live use by testing the control functions with the transmitter powered on.
Usage recommendations
Use the controller with the specific Sennheiser transmitters it is designed for and consult the transmitter documentation to confirm which remote functions are supported. Avoid exposing the cable and connector to heavy strain or moisture; store the accessory coiled and protected when not in use.
