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.\u003c\/p\u003e\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003eThe 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 \u003ca href=\"https:\/\/creationnetworks.net\/search?q=CHG%20412\"\u003eCHG 412 charger\u003c\/a\u003e, and \u003ca href=\"https:\/\/creationnetworks.net\/search?q=DLR%20400%20RCH\"\u003eDLR 400 RCH receivers\u003c\/a\u003e for listen-only participants.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull-duplex intercom\u003c\/strong\u003e — Real-time two-way communication without push-to-talk.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdvanced Communication Mode\u003c\/strong\u003e — Leader\/guest roles, up to four subgroups, all-call, and private calls.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLicense-free 2.4 GHz\u003c\/strong\u003e — Frequency-hopping operation resists interference;
