This selection guide provides recommended frequencies and the estimated number of compatible systems for all Shure Wireless Systems and PSM Wireless Systems. Shure Applications Engineering updates this tool regularly based on the database of U.S. television stations that is managed by the Federal Communications Commission.
NOTE: This Frequency Finder tool should be used as a guideline and planning tool. Recommended frequencies are calculated by avoiding conflicts with local television broadcast - the primary source of interference to wireless microphone systems. It cannot predict every possible source of local interference that can affect a wireless audio system. Using the Frequency Finder tool does not guarantee freedom from interference. Other local sources of interference (such as low power TV stations) may be present and can adversely affect the performance of the wireless system.
