This 4-person kit supports up to four users communicating at the same time in full-duplex mode. Every participant can talk and listen simultaneously, enabling natural collaboration during meetings, productions, or on-site operations.
The system is designed for professional settings that demand reliable two-way communication. It performs exceptionally well in meetings, team projects, production floors, educational institutions, and field environments where clarity and coordination are essential.
Each transmission is protected by 128 + 87-bit encryption and advanced frequency-hopping spread spectrum (FHSS) technology. This ensures all conversations remain private and stable, even in areas with multiple wireless devices or overlapping signals.
Each DLT 400 transceiver offers up to 16 hours of continuous operation, allowing users to work through long sessions or multiple shifts before recharging is required. The Auto Sleep Mode further extends battery life during idle periods.
Yes. The system is fully scalable: additional transceivers can be added, and multiple Digi-Wave systems can be linked together to accommodate larger groups while maintaining full-duplex, interference-free communication.
Extremely easy. The lightweight CCS 029 DW carrying case keeps all components secure and organized. Setup involves powering on the transceivers, syncing them to the same group channel, and beginning communication immediately.
This compact system is ideal for small teams such as business managers, tour operators, event coordinators, and technical crews who require reliable, hands-free communication without the complexity of traditional wired systems.
