Williams AV DWS INT 5 400 RCH – Digi-Wave 400 Wireless Interpretation System

Product Overview

The Williams AV DWS INT 5 400 RCH delivers simultaneous language interpretation for large audiences using the Digi-Wave 400 digital spread-spectrum wireless platform. The rechargeable package equips five interpreters with DLT 400 transceivers and serves fifty listeners with DLR 400 RCH receivers, covering four languages plus the floor feed. With no transmitter rack, no antenna runs, and license-free 2.4 GHz operation, it is one of the fastest interpretation systems for AV integrators to deploy in conference centers, courts, and multilingual worship services.

Product Description

Digi-Wave 400 is a full-duplex, two-way wireless communication platform engineered for simultaneous interpretation, intercom, and guided listening. In this DWS INT 5 400 RCH configuration, each interpreter wears a MIC 158 headset microphone connected to a pocket-sized DLT 400 transceiver, transmitting a dedicated language channel that listeners select on their DLR 400 RCH receivers. The platform supports up to six simultaneous talkers and an unlimited listener count, and in interpretation mode handles one floor language with up to 14 translated languages — ample headroom beyond the four languages this kit covers out of the box.

The frequency-hopping algorithm in the 2.4 GHz ISM band sidesteps Wi-Fi congestion and analog FM interference, while optional 87+128-bit encryption with PIN protection secures sensitive proceedings. The digital audio path reduces background noise and compensates for poor room acoustics and listener distance, which matters in reverberant courtrooms and large commercial meeting spaces. Because nothing is rack-mounted or hard-wired, the same kit can move between an all-hands room on Monday and an off-site training facility on Tuesday.

Five CHG 412 12-bay chargers keep the entire rechargeable fleet event-ready, and the CCS 054 wheeled case organizes transport and storage. The system also doubles as a wireless intercom or tour communication system when interpretation is not in session, increasing utilization of the investment. See related assistive listening and interpretation equipment in the Williams AV collection, or add the IC-2 interpreter console for relay interpretation workflows.

Frequently Asked Questions

Can listeners hear the floor language as well as interpretation?

Yes. The Digi-Wave 400 interpretation mode carries the floor language alongside up to 14 translated channels, and listeners switch channels directly on the DLR 400 RCH receiver.

Does this system integrate with an existing sound system?

Yes. The DLT 400 accepts line input over USB-C with adjustable level, so a feed from your mixing console or DSP can be transmitted to all receivers — useful when the floor audio originates from a house PA in a conference room or auditorium.

What is the practical coverage range?

Up to 900 feet (274 m) depending on construction and RF environment. The 2.4 GHz signal also passes through glass and partition walls, which supports interpreter booths and adjacent viewing rooms.

How long does setup take for an AV integrator or event technician?

Minutes. There is no base station, transmitter rack, or antenna cabling — power up the transceivers and receivers, confirm the group and channel assignments on the OLED displays, and distribute units to interpreters and listeners.

Can I add more receivers later?

Yes. Listener count is unlimited; add DLR 400 RCH or battery-powered DLR 400 ALK receivers at any time without reconfiguring the system.

What support and warranty apply?

The system carries a 2-year Williams AV warranty against component failure and manufacturing defects (6 months on internal batteries, 90 days on cables and power supplies), and Creation Networks provides pre-sale system design assistance and post-sale support.
