Product Overview
The Dukane WMIC2B system provides an instructor with added voice power to be heard by everyone in a classroom setting, which helps improve retention and learning.
This system consists of a small, lightweight lanyard-held transmitter with an attachable lapel microphone that sends the voice signal via a digital encoded bit stream at high speed to the receiver. The receiver converts the digital bitstream back to regular audio output sent to a 30W stereo audio amplifier and speakers. This results in a conventional sound enhancement or voice augementation system. There are 20 channels available from 2.4GHz to 2.480GHz for operation.
