The Digi-Wave™ system 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 Digi-Wave communication system allows users to listen and talk to one another wirelessly in a variety of scenarios.
A Digi-Wave system consists of at least one transceiver (DLT 400 sold separately) and various combinations of transceivers and receivers (DLR 400 RCH or DLR 400 ALK). Combinations of one or more DLT’s and DLR’s can be used to facilitate different events, depending on what needs to be spoken and what needs to be heard. It is commonly used for guided tours, language interpretation, intercom, and hearing assistance.
