What are Groups and Channels?
To minimize interference, Shure wireless systems organize RF bands into predefined groups and channels. A group is a set
of compatible frequencies within a frequency band. A single frequency within a group is a channel. Tune a receiver and trans
mitter to the best available channel within its group to set up your system.
Note: Because groups are banddependent, some systems don't have multiple groups. Singlegroup bands have the same RF performance as those with mul
tiple groups.
