These days contactless communication is essential to get through our day-to-day lives. People are figuring out ways to work from home and socially distance, but what if this isn't possible in your line of work? Williams AV has you covered with the Digi-Wave 400, a full duplex portable, wireless 2-way, system for short range communication. The Digi-Wave is ideal for social distancing in a variety of applications including teaching, training, and interpreting. It can also be used in
courtrooms, classrooms, hospitals, restaurants and warehouses. In addition, the Digi-Wave400 is a cost-effective alternative to other expensive 2-way radios.

The Digi-Wave 400 system is a digital spread-spectrum (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).
