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).
