    DLR 400 RCH - Overview

    The WILLIAMS AV DLR 400 RCH Digi-Wave™ system is a digital spread-spectrum (DSS), simultaneous two-way wireless listening system. Using it's frequency-hopping algorithm, it avoids interference and is a very secure method of communication. The Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios.
