The Williams AV DWS INT 5 400 RCH is part of the Digi-Wave 400 line, a 2.4 GHz digital spread-spectrum (DSS) wireless platform built for secure two-way audio over frequency-hopping channels that resist interference. Digi-Wave transceivers and receivers support PIN-protected 87-bit or 87+128-bit encryption, OLED displays, and a working range up to roughly 900 feet depending on environment. It's configured as an interpretation system, letting a presenter's audio be relayed live in multiple languages to listeners over dedicated Digi-Wave channels.
