It’s a professional wireless intercom system that combines FM and Wi-Fi audio delivery. It’s designed for venues that need clear, one-way communication, assistive listening, and network-ready audio distribution.
Dante allows digital audio to be routed over Ethernet into existing AV networks. This simplifies cabling, improves audio reliability, and makes the intercom system easier to integrate into professional installations.
This configuration is ideal for mid-sized venues such as courtrooms, lecture halls, houses of worship, and council chambers that need professional audio without deploying a large receiver fleet.
R37 receivers use a simple seek button for channel selection, making them easier for public users. R38 receivers include OLED screens and manual controls, which are better suited for managed or staff-operated environments.
Yes. The FM T55C D transmitter supports Wi-Fi streaming, allowing users to connect via the WaveCAST app on iOS or Android devices while others use FM receivers simultaneously.
The system supports unlimited listeners. You can add more FM receivers at any time, and Wi-Fi listeners are only limited by the venue’s network capacity.
Professional installation is recommended, especially when using Dante and a remote antenna. The included rack panel kit and network controls are designed for permanent, integrator-led deployments.
