About Williams Sound DWS TGS 11 400

- DLT 400 Transceiver & DLR 400 RCH 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.

• 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
