FREQUENCY SELECTION GUIDE
The Shure UHF Wireless System is designed for maximum flexibility and versatility
in a variety of applications. Up to 20 Shure UHF Wireless Systems can be operated simultaneously in a single installation using the frequency compatibility groups. Groups
A1 and A2 are included in a “master list” that covers all frequencies in the 782 to 806
MHz band. When using the U4D dual receiver, maintain a minimum of 500 kHz separation between each receiver in the U4D. Please contact the Shure Customer Service Department If you need additional information or assistance in frequency selection and
setup.
COMPATIBILITY GROUPS
The Shure UHF Wireless System includes seven 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.
Use frequencies from Groups 1-3 in locations where TV channels 66, 67, 68, and 69
are NOT in use. If any of these TV channels are present in your location, use frequencies from one of the Groups 4-7 as indicated in the following table. Use the UHF TV
Channel Guide in this supplement to determine which TV channels may be present in
your area.
NOTE: The Group and Channel for any frequency in the UHF band as well as the TV
channel corresponding to that frequency is displayed on the U4 receiver. If the
receiver displays a TV channel that is active in your area for a frequency you have
selected, choose a different frequency.
