Williams AV DWS INT 5 400 ALK – 4-Language Interpretation System, Alkaline

Product Overview

The Williams AV DWS INT 5 400 ALK is a complete simultaneous interpretation system for four languages plus floor, built on the encrypted Digi-Wave 400 wireless platform. The package combines five rechargeable DLT 400 transceivers for interpreters with fifty alkaline-powered DLR 400 ALK receivers for listeners — a practical configuration for venues that prefer field-swappable AAA batteries over managing a large recharging fleet. As a portable wireless interpretation system with no base station, it suits courts, conference facilities, and houses of worship that need multilingual audio on short notice.

Product Description

In this alkaline configuration of the Digi-Wave 400 Series interpretation system, interpreters transmit through DLT 400 digital transceivers with MIC 158 headset microphones while the audience listens on lightweight DLR 400 ALK receivers running on standard AAA alkaline cells. Each pair of AAA batteries delivers up to 30 hours of listening, and a fresh set installs in seconds — an advantage for rental houses, large worship campuses, and event AV teams that cannot guarantee charger access between sessions. Fifty BAT 010-2 alkaline batteries are included to get the system in service immediately.

The platform transmits digital spread-spectrum audio in the license-free 2.4 GHz ISM band, with a frequency-hopping algorithm that resists interference from Wi-Fi and other wireless systems common in commercial meeting spaces. Optional 87+128-bit encryption with a PIN code keeps proceedings confidential, which matters for judicial interpretation and government sessions. The system supports one floor language and up to 14 translated languages, so the four interpreter channels supplied here can scale with additional DLT 400 transceivers as needs grow.

The five rechargeable transceivers charge in the included CHG 412 12-bay charger, and five DW ACC PAC4 accessory packs plus the CCS 054 wheeled carry case support transport and daily operations.

Frequently Asked Questions

Why choose the alkaline version over the rechargeable system?

The ALK package suits venues without secure charging space or with back-to-back events: spent AAA batteries swap out in seconds and there is only one charger to manage (for the five rechargeable transceivers). The RCH version is more economical long term where overnight charging is practical.

How long do the receiver batteries last?

Up to 30 hours on a pair of AAA alkaline cells — typically several event days. An auto sleep mode engages after 5 minutes without an RF signal to extend battery life further.

Can this system also run intercom or guided-tour audio?

Yes. The Digi-Wave 400 platform supports two-way intercom with up to six simultaneous talkers and one-way tour-guide operation, so the same investment serves multiple use cases between interpretation events.

Is the transmission secure?

Yes. Optional 87+128-bit encryption with an encryption PIN and settings lock secures the signal for confidential courtroom, legal, and government interpretation.

Will it interfere with our Wi-Fi network?

The frequency-hopping spread-spectrum design distributes transmission across 2402–2476 MHz, allowing the system to coexist with enterprise Wi-Fi in conference rooms and commercial meeting spaces without licensing or channel coordination.

What warranty applies?

Williams AV provides a 2-year warranty against component failure and manufacturing defects; cables and power supplies carry 90-day coverage. Creation Networks assists with configuration and after-sale support.
