Product Overview
The Williams AV DLT 400-ACM is a Digi-Wave 400 Series transceiver with the Advanced Communication Module, built for portable two-way production intercom. It provides full-duplex, license-free 2.4 GHz communication with channel naming, subgroups, and private-call functions, making it a flexible wireless intercom transceiver for broadcast studios, houses of worship, and event production. The bodypack transceiver operates without a fixed base station.
Product Description
The DLT 400-ACM is a bodypack Digi-Wave transceiver configured for Advanced Communication Mode (ACM), a full-duplex intercom workflow with leader and guest roles, up to four subgroups, all-call, and private calls. It operates in the license-free 2.4 GHz band with a frequency-hopping algorithm to resist interference in RF-dense venues, so no frequency coordination is required. Any unit can be assigned as the main sync unit to define coverage, and units can be wired to a Digi-Wave Connect (DWD 401) for constant power in fixed positions. The transceiver charges over USB-C or a compatible Williams AV charging station, with a full charge in about five hours from its internal lithium-polymer battery. A 3.5 mm jack accepts headsets, earphones, or neckloops for talk and listen. The DLT 400-ACM is compatible across the Digi-Wave 400 Series and pairs with production headsets, the CHG 412 charger, and DLR 400 RCH receivers for listen-only participants.
