Digi-Wave 400 Series Wireless Intercom And Interpretation System
Digi-Wave™ 400 Series
WIRELESS INTERCOM AND INTERPRETATION SYSTEM
The Digi-Wave 400 system is a digital spreadspectrum (DSS), simultaneous two-way wireless communication system. The system makes hearing easier in everyday situations
by reducing background noise and compensating for poor room acoustics or distance from the sound source. Its frequency-hopping algorithm avoids interference and is a very secure method of communication.
Every Digi-Wave System includes at least one two-way transceiver (DLT 400) and one or more receivers (DLR 400 RCH or DLR 400 ALK), depending upon the application.
The system is commonly used for intercom, with up to six people able to speak simultaneously and even more listening. It’s also ideal as a human interpretation system that supports one floor language and up to 14 translated languages. Digi-Wave systems are also frequently used with guided tours – with one or more tour guides (2-way), with audience participation (2-way) or without audience participation (1-way listen only).
