5.1.1 MIC/USB Connection
The MIC/USB connector allows connection of the microphone or another accessory device such
as a Phraselator, a CD player, or a commercial audio device, such as the iPod. Audio played
from an external device using this connection will be mixed with any audio being played
through the LRAD’s Control Module: it will not override any other audio being played. This
connection is accomplished through the optional Auxiliary Audio cable.

The MIC/USB connector allows a USB connection to a PC, which can be used to download
prerecorded audio files onto the Control Module. This connection can also be used to update
the firmware in the Control Module.
