The ACM version introduces advanced communication features like subgroup division, All-Call capability, and offline control programming, making it ideal for complex productions and multi-department coordination.
Unlike fixed base systems, the ACM allows any device in the group to act as the digital access point. This maximizes range, reduces dead zones, and allows teams to stay connected throughout large venues.
Yes. The ACM supports up to four independent subgroups, each with customizable names. This setup lets teams like stage, lighting, and security communicate on separate channels while remaining part of the same network.
All-Call allows designated leaders to broadcast messages to all active subgroups simultaneously. This is ideal for stage cues, emergency alerts, or global team announcements during live productions or broadcasts.
Yes. The Control Function enables administrators to program all settings offline through a designated ACM device, allowing updates without interrupting active communication sessions.
Yes. Existing DLT 400 units with firmware from January 2021 or later can be upgraded to include ACM functionality. Contact us for update assistance or firmware installation.
It’s used by broadcast directors, theater crews, event producers, and stage managers who need dependable, interference-free intercom communication with full mobility and subgroup flexibility.
