FREQUENCY LISTS
The following tables list groups of frequencies in megahertz. Please note that
only frequencies in Group 1 are compatible.
Group 1 contains 10 compatible frequencies which are derived from a
combination of fixed site (”Multi UHF High and Low”) frequencies as well as
”Indoor Use at Fixed Site” frequencies.
NOTE: See also the additional compatible frequency sets for Group 1.
Group 2 contains 14 fixed site frequencies taken entirely from the Multi UHF
High and Low band.
Groups 3 and 4 contains all frequencies within the Indoor Use at Fixed Site
band, in 25 kHz increment steps.
The master list (Groups A1–A3) covers all frequencies in 25 kHz increments
within the 854–862 MHz band.
Shure recommends that you maintain a 500 kHz separation between each
receiver in the U4D dual receiver. Please contact the Shure Customer Service
Department if you need additional information or assistance in frequency selection
and setup.
NOTE: While the Shure U4 receiver may display each ”FREQUENCY” mode for all
frequencies in 2 5 kHz steps within the 854–862 Mhz band, your transmitter only tunes
to legally allowed frequencies within that band.
