About Williams Sound DWS INT 3

- DLT 400 Transceiver & DLR 400 ALK Receiver -

The 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.

A Digi-Wave system consists of at least one transceiver (DLT 400) 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. Typical scenarios include:

• Guided Tours - with one or more tour guides (2-way), with audience participation (2-way), or without audience participation (1-way)

• Language Interpretation - one or more interpreted languages transmitted to audience (1-way)

• Intercom - with up to six people able to speak simultaneously, and even more listening

• Hearing Assistance - featuring boosted audio for improved comprehension

Note: The DLR 400 RCH uses alkaline batteries. If a rechargable version is preferred, see the DLR 400 RCH.
