FREQUENCY SELECTION GUIDE
The Shure UHF Wireless System is designed for maximum flexibility and versatility
in a variety of applications. Up to 24 Shure UHF Wireless Systems can be operated
simultaneously in a single installation using the frequency compatibility groups.
Please contact Shure Incorporated if you need additional information or assistance in
frequency selection and setup.
Compatibility Groups
The Shure UHF Wireless System includes 10 groups of compatible channels. If you
are using more than one receiver in the same area, we recommend that you set the
receivers to different frequencies within the same group.
