Williams AV DLT 400 Digi-Wave 400 Digital Wireless Listening System Transceiver

Williams AV DLT 400 Digi-Wave 400 Digital Wireless Listening System Transceiver

TheDigi-Wave system is a digital spread-spectrum (DSS), simultaneous two-waywireless listening system. Using it’s frequency-hopping algorithm, it avoidsinterference and is a very secure method of communication. The Digi-Wavecommunication system allows users to listen and talk to one another wirelesslyin a variety of scenarios.

A Digi-Wavesystem consists of at least one transceiver (DLT 400) and various combinationsof transceivers and receivers (DLR 400 RCH or DLR 400 ALK). Combinations of oneor more DLT’s and DLR’s can be used to facilitate different events, dependingon what needs to be spoken and what needs to be heard. Typical scenariosinclude:
Guided Tours- with one or more tour guides (2-way), with audience participation (2-way), orwithout audience participation (1-way)
LanguageInterpretation – one or more interpreted languages transmitted to audience(1-way)
Intercom -with up to six people able to speak simultaneously, and even more listening
HearingAssistance – featuring boosted audio for improved comprehension
