Williams AV DWS INT 4 400 RCH – Rechargeable Interpretation System, 21 Listeners

Product Overview

The Williams AV DWS INT 4 400 RCH is a rechargeable wireless interpretation system sized for mid-capacity venues: up to three presenters or interpreters and twenty-one listeners. Built on the Digi-Wave 400 digital spread-spectrum platform, it transmits encrypted, license-free 2.4 GHz audio with no base station or rack-mount equipment, making it a strong fit for courtroom interpretation, corporate training rooms, and multilingual worship services where portability and fast setup drive the specification.

Product Description

This DWS INT 4 400 RCH package equips three talkers with DLT 400 digital transceivers and MIC 144 headset microphones, while twenty-one listeners receive on rechargeable DLR 400 RCH units with EAR 022 surround earphones. The Digi-Wave 400 platform supports one floor language plus up to 14 interpreted languages and accommodates up to six simultaneous talkers, so the same kit handles simultaneous interpretation, two-way intercom for production teams, and guided tours with or without audience talk-back.

Every unit in this configuration is rechargeable. Two CHG 412 PRO 12-bay chargers — each built into a CCS 056 carry case — store, transport, and charge the entire fleet, a workflow that AV and facilities teams appreciate: units come back from an event, drop into the case, and are charged in about five hours for the next session. Receivers run up to 32 hours per charge and transceivers up to 16 hours of talk time, comfortably outlasting full-day proceedings.

Digital spread-spectrum transmission with frequency hopping reduces background noise, compensates for room acoustics, and resists interference in Wi-Fi-dense commercial meeting spaces. Optional 87+128-bit encryption with PIN protection secures confidential legal and government sessions.

Frequently Asked Questions

What makes the CHG 412 PRO charging cases useful for AV teams?

Each CHG 412 PRO is a 12-bay charger built into a CCS 056 transport case, so the system stores, travels, and charges in the same enclosure. After an event, units drop into their bays and are ready in about five hours — no separate charging station to set up.

Can I use this for both interpretation and staff intercom?

Yes. The DLT 400 transceivers operate in interpretation mode (floor plus up to 14 languages) or full-duplex intercom mode with up to six simultaneous talkers, so production crews can reuse the system between multilingual sessions.

How many listeners can the system ultimately support?

Listener count is unlimited. Add DLR 400 RCH or DLR 400 ALK receivers at any time — they join the existing group/channel structure without reprogramming.

Does it integrate with a house audio system?

Yes. The DLT 400's USB-C line input accepts a feed from a mixer or DSP at adjustable level, letting you transmit program audio from the room's sound system as the floor channel.

Is the wireless link secure for legal proceedings?

Optional 87+128-bit encryption with an encryption PIN and settings lock secures the channel, meeting the confidentiality expectations of courtroom and government interpretation deployments.

What warranty and support are included?

Williams AV provides a 2-year warranty against component failure and manufacturing defects with 6 months on internal batteries. Creation Networks offers configuration guidance and post-sale support for commercial installations.
