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.
