Why Choose the FreeSpeak II BASE II?
Unmatched Flexibility: Unlike single-band systems, the BASE II supports both 1.9 GHz and 2.4 GHz FreeSpeak II beltpacks on the same base station. This means you can mix frequency bands based on your RF environment without needing multiple base stations.
Scale to Your Needs: Start with a few beltpacks and expand to 25 users as your production grows. The system supports up to 10 active transceivers via FSII splitters, giving you extensive coverage for large venues or outdoor events.
Rapid Configuration: The browser-based Core Configuration Manager (CCM) eliminates the need for specialized software. Configure your entire system, assign user roles, and monitor RF performance from any device with a web browser.
