Frequently Asked Questions

Digital transmission eliminates much of the noise and interference common with analog, and the AES-256 encryption provides a level of security you can’t get with analog systems.
The K51 band is generally well-managed, but it's always best to check local regulations and potential interference before deploying it for a large event.
The transmitter is designed for Shure capsules; while swapping is possible, it's not officially supported and may void the warranty, plus you’ll lose the intended performance characteristics.
