The Digi-Wave tour guide system allows tour group participants to listen and talk to one another wirelessly in a variety of scenarios. A Digi-Wave system consists of at least one transceiver (model DLT 400) and various combinations of more transceivers (for 2-way) an/or listen-only receivers (models 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 who needs to speak and who needs to listen. 

Digi-wave DLT 400 transceiver

The Digi-wave DLT 400 is a two-way transceiver, meaning that it can transmit and receive audio simultaneously.

Digi-wave DLR 400 receiver

The Digi-wave DLR 400 is a receiver only. Users of DLR 400 receivers can only hear what is being broadcast by DLT(s); they cannot create any audio.

There are two models of receiver: the DLR 400 ALK that uses alkaline AA batteries and the DLR 400 RCH which is rechargeable and compatible with the DLT . 

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 (2-way)

There are many more scenarios of course and we're happy to help choosing the best Digi-wave solution for your specific application.

The Williams-AV Digi-Wave 400 Series is backward compatible with the Digi-wave 300 series (with limited features). It is not backward compatible with any earlier Williams Sound Digi-wave transceivers or receivers (DLT 100, DLT 100 2.0, DLR 50, DLR 60, and DLR 60 2.0).
