Frequently Asked Questions

The automatic frequency selection is much faster and more intelligent than older Shure systems, adapting quickly to interference and offering a broader selection of clean channels.
Absolutely; the convenience and extended runtime justify the cost, especially for regular performance use. It eliminates the need to constantly swap AA batteries.
While the 72 MHz bandwidth is generous, very crowded RF environments might still require careful channel selection and coordination with the venue’s technical staff.
