A wireless intercom system enables teams to communicate hands-free and in real time without cables or fixed stations. It’s commonly used in broadcast production, theaters, live events, and corporate environments where mobility and clarity are essential.
Unlike traditional systems that rely on a central base station, Digi-Wave ACM lets any transceiver act as the access point. This gives users greater mobility, faster setup, and broader coverage in complex production spaces.
The included 12-person kit supports up to twelve active users, with each DLT 400-ACM unit functioning as a transceiver for full-duplex communication. Additional units can be added for larger teams.
This wireless intercom system offers a range of up to 900 feet (274 meters), depending on the environment, maintaining stable, full-duplex digital communication throughout event spaces and production floors.
Yes. The Digi-Wave ACM system allows up to four subgroups for targeted communication; ideal for managing departments like lights, stage, audio, and camera teams.
The all-call feature lets directors or team leads send announcements to all subgroups instantly. It’s perfect for stage cues, broadcast timing, or emergency updates during live productions.
Each unit provides up to 16 hours of continuous operation on a full charge, ensuring reliable, all-day use for long rehearsals, broadcasts, or event setups.
