Williams AV DWS INT 5 400 RCH – Rechargeable 4-Language Interpretation System

Product Overview

The Williams AV DWS INT 5 400 RCH is a rechargeable wireless language interpretation system built on the Digi-Wave 400 platform, supporting four interpreted languages plus the floor channel. Designed for simultaneous interpretation in courtrooms, conference centers, and houses of worship, this complete package pairs five DLT 400 transceivers with fifty DLR 400 RCH rechargeable receivers so a facility can deploy multilingual audio without a base station or rack-mount transmitter. Encrypted 2.4 GHz digital spread-spectrum transmission keeps interpretation channels secure and free of FM interference, making it a dependable choice for commercial AV interpretation equipment standardization.

Product Description

This DWS INT 5 400 RCH package is the rechargeable, large-audience configuration of the Digi-Wave 400 Series interpretation system. Interpreters speak through DLT 400 portable digital transceivers fitted with MIC 158 headset microphones, while up to fifty listeners select their language on DLR 400 RCH receivers with EAR 022 surround earphones. The system supports one floor language and up to 14 translated languages, so the four-interpreter complement included here can be expanded later with additional transceivers as language requirements grow.

Because Digi-Wave 400 uses frequency-hopping digital spread-spectrum in the 2.4 GHz ISM band, no FCC licensing is required and the system coexists with Wi-Fi in commercial meeting spaces. Optional 87+128-bit encryption with a PIN code protects confidential proceedings — a key requirement for legal, government, and corporate interpretation work. Coverage reaches up to 900 feet line of sight, and the entire kit is portable: there are no rack-mounted components, AC-powered transmitters, or antennas to install, which simplifies deployment for AV integrators handling multi-room or traveling events.

Power management is handled by five CHG 412 12-bay drop-in chargers that replenish both transceivers and receivers in roughly five hours, with receivers delivering up to 32 hours of listening per charge. Silicone skins and a CCS 054 wheeled carry case round out the package for transport between venues. For mixed assistive listening and interpretation projects, browse the full Williams AV collection at Creation Networks, or pair this system with the Williams AV IC-2 interpreter control console for booth-based workflows.

Frequently Asked Questions

How many languages can this interpretation system support?

As shipped, the five DLT 400 transceivers support four interpreted languages plus the floor channel. The Digi-Wave 400 platform scales to one floor language plus up to 14 translated languages by adding transceivers, so the system grows with your language access requirements.

Do I need an FCC license or frequency coordination?

No. The system operates in the license-free 2.4 GHz ISM band using frequency-hopping spread-spectrum, which automatically avoids interference from Wi-Fi and other RF devices in commercial venues.

Is the audio secure enough for courtrooms and government use?

Yes. Digi-Wave 400 supports 87+128-bit encryption with an encryption PIN and a settings lock, making it suitable for confidential legal proceedings, government meetings, and corporate sessions where signal privacy is mandatory.

How does charging work for 50 receivers?

The package includes five CHG 412 12-bay drop-in chargers — 60 total bays — so the entire fleet of transceivers and receivers recharges overnight in roughly five hours with no cables to plug into individual units.

Is this system compatible with older Digi-Wave 300 equipment?

The DLT 400 maintains 87-bit encryption compatibility with the Digi-Wave 300 Series, so DLT 300 and DLR 360 units can interoperate with some feature limitations during a phased migration.

What warranty does Williams AV provide?

Williams AV covers the system with a 2-year warranty against component failure and manufacturing defects, with 6 months of coverage on internal batteries and 90 days on cables and power supplies. Creation Networks supports the system through specification, deployment, and after-sale service.
