Shure UHF-R Wireless
Receiver Controls and Connectors쐃SYNC Infrared (IR) port. Transmits group, channel, and other
settings to a transmitter. See page 15.
쐇Squelch LEDs.
• Blue (On) =Transmitter signal detected
• Off= no signal or signal squelched because of poor reception
or no tonekey
NOTE: The receiver will not output audio unless at least
one blue LED is illuminated.
쐋RF LEDs. Indicate RF signal strength from the transmitter at
each antenna and diversity condition.
•Amber=normal
• Red= overload (greater than –25 dBm)
쐏Audio LEDs. Indicate audio signal strength from transmitter.
• Green= signal present
• Yellow= normal peak
•Red=overload
To correct this level, adjust the transmitter gain.
쐄Indicates the name and range of receiver frequency band.
쐂LCD Interface. Provides a convenient way to program the
receiver from the front panel (see detail on next page).

쐊Power switch. Powers the unit on and off.
쐎AC mains power input, IEC connector. 100–240 Vac.
쐅AC mains power passthrough (unswitched). Use with an IEC
extension cable to supply AC power to another device.
쐈Diversity antenna inputs A and B.
Note: Antenna inputs are DC biased. Use only antenna
combiners and accessories listed in page 19. Some
types of antenna splitters or other products may short
the DC power and damage the receiver.
쐉Mic/Line switch. Changes output level –30 dB (XLR output
only).
씈Electrically balanced XLR output jack
씉Lift/GND switch. Lifts ground from Pin 1 of the XLR connec-
tor (default = GND).
씊Impedance balanced 1/4” output jack (200:)
씋USB jack for computer interface.
씌RJ-45 jack for Ethernet network interface. Accepts both regu-
lar and “ruggedized” RJ-45 plugs.
씍Temperature-activated fan ensures top performance in high
temperature environments. Clean fan screen as needed to
remove dust.
