UR4S+
Wireless Receiver

sync
 SYNC Infrared (IR) port. Transmits group, channel, and
other settings to a transmitter. See page 14.
 Squelch 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.
 RF LEDs. Indicate RF signal strength from the transmitter
at each antenna and diversity condition.
• Amber = normal
• Red = overload (greater than –25 dBm)
4 Audio LEDs. Indicate audio signal strength from
transmitter.
• Green = signal present
• Yellow = normal peak
• Red = overload
To correct this level, adjust the transmitter gain.
5 Indicates the name and range of receiver frequency
band.
 LCD Interface. Provides a convenient way to program the
receiver from the front panel (see detail on next page).
7 Monitor. 1/4" output jack and volume knob for
headphones.
• Monitor Clip LED indicates headphone audio is
clipping.
• Dual models: Push the knob to switch from receiver
Note: The diagram above represents the UR4S single channel receiver. The UR4D dual channel receiver is functionally identical to the UR4S, adding a
second LCD interface and set of output jacks for channel 2.

 Power switch. Powers the unit on and off.
 AC mains power input, IEC connector. 100–240 Vac.
 AC mains power passthrough (unswitched). Use
IEC extension cables to connect up to five UR4+
receivers to a single AC power source.
 Diversity 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.
 Mic/Line switch. Changes output level 30 dB (XLR
output only).
 Electrically balanced XLR output jack
 Lift/GND switch. Lifts ground from Pin 1 of the XLR
connector (default = GND).
 Impedance balanced 1/4" output jack (200Ω)
 USB jack for computer interface.
 RJ-45 jack for Ethernet network interface. Accepts both
regular and "ruggedized" RJ-45 plugs.
 Temperature-activated fan ensures top performance in
high temperature environments. Clean fan screen as
needed to remove dust.
 The RF distribution ports pass the RF signal from one
receiver to the next, allowing a maximum of 10 receivers
to share a single pair of antennas.
