The AKG CBL31 WLS is a professional boundary layer microphone for wireless use. It's ideal for meeting rooms, court rooms and conferencing as well as houses of worship.

The shock absorbing heavy duty tabletop housing includes the well-known CK31 cardioid capsule from the DAM Series.

Various AKG pocket transmitters fit into the housing to transform the station into a complete wireless solution.

A rugged mute switch (more than 25.000 switching cycles) controls the microphone and an LED bar to clearly show the status. A 3,5 mm input jack plug allows connection of either up to 4x AKG CBL410 or a laptop to transmit the audio signal of a presenter to the local PA system.

  • Heavy duty - firm fit and shock absorbing
  • Cardioid polar pattern - 120° angle for more mobility in front of mic
  • Select from AKG WMS40/45/420/470 and DMS700 transmitter options - enables flexibility for all budgets and needs
  • MUTE switch combined with LED bar - clear microphone status for all participants of a meeting 
  • 3.5 mm input - cascade up to four CBL410 to cover a larger meeting table with one wireless channel


This is perfect for use with the instrument microphone set or presenter set as they include a suitable beltpack transmitter - see related items.
