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 INT 4 400 RCH Digi-Wave Interpretation System includes the DLT 400 transceiver and the DLR 400 RCH rechargeable receiver, which allows users to translate and interpret in a variety of scenarios.
