The transceiver in the system is DLT 400 from the Digi-Wave™ system. It is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system. Using a frequency-hopping algorithm, it avoids interference and is a very secure method of communication. The Williams AV DWS PCS 2 400 Digi-Wave Personal Communication System allows users to listen and talk to one another wirelessly in a variety of scenarios. Headset microphone MIC 144 is another component to this system. It has a TRRS 3.5 mm plug and is for use with Digi-Wave DLT 400 transceiver only.
