The Digi-Wave™ system is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system. Using its frequency-hopping algorithm, it avoids interference and is a very secure method of communication.
The Williams Sound DWS PCS 2 400 Digi-Wave Personal Communication System includes two DLT 400 transceivers, which allow users to listen and talk to one another wirelessly in a variety of scenarios.
