Problem Solution
The microphone 
is connected, but 
there’s no sound.
•  Make sure both XLR connectors on the cable are fully inserted into the 
plugs on the microphone and input device (conferencing system or mixing 
board).
•  Make sure your microphone is connected to an XLR port with phantom 
power, and that the phantom power is turned on.
•  If the LED indicator is off, touch the sensor pad to unmute the microphone. 
See Talk/Mute above about programming the touch pad.
•  Refer to your AV conferencing system’s user manual to ensure the input 
settings are correct.
