Professional Boundary Layer Microphone For Wireless Use



The CBL31 WLS is a professional boundary layer microphone. It is based on a heavy-duty tabletop mechanics
and includes the well-known cardioid capsule CK31 from the DAM Series. Due to its heavy weight it is very
well shock absorbing and holds the microphone firm on place. 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 WMS40/45/470 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
