The Williams AV DWS PCS 3 400 RCH Digi-Wave Personal Communication System allows users to listen and talk to one another wirelessly in a variety of scenarios.
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 receiver with this system is rechargeable using CHG 412 12-bay charger (sold separately). Lavalier microphone MIC 190 is another component to this system. The lav mic has an omnidirectional polar pattern and clips conveniently to your shirt.
