The Shure Model UA845 is an amplified, UHF Antenna Distribution System
that expands a wireless microphone system by splitting one pair of antennas
to multiple Shure UR4 or Shure ULX4 wireless receivers. It also amplifies
RF signals to compensate for insertion loss due to splitting signal power to
mulitple output connectors. Each UA845 allows up to four receivers to use
the same antennas. CASCADE connectors allows connections to a fifth re­ceiver or a second UA845. There are also power connectors for powering
Shure UHF Wireless systems.Each system contains the following items:

•

•

•

The Shure Model UA845 ensures maximum sensitivity and signal processing
capability, providing the widest radio range possible for the largest number
of wireless receivers. To get the most from this system, follow these guide­lines:

•

When using long runs of cable for remote-mounted antennas, use the
UA830 In-Line RF Amplifier and the Shure Model UA825 or UA850 Re­mote Antenna Extension cables (RG-8/X or equivalent), which have low
loss at UHF operating frequencies

INSTALLING FRONT-MOUNTED ANTENNAS

The UA845 comes equipped for front-mounted antennas. Front-mounting
improves RF performance of the system by moving the antennas to the front
of the rack. When a unit is located in a rack, antennas should be either front­or remote-mounted.

1. Insert the bulkhead adapters through the holes in each bracket, and
secure them from each side, using the supplied hardware.

2. Connect the supplied antenna cables to the receiver antenna inputs and
adapters.

3.

Install the antennas onto the bulkhead adapters protruding through the
front panel.

NOTE: For the best results, point the antennas up and away from each
other at 45angles from vertical. This ensures the best possible reception
and greatly reduces the possibility of signal dropout. Always perform a
walk-through test of the system in the performing area before using a
wireless system.

INSTALLING REMOTE ANTENNAS

Remote-mounted antennas have the advantage of being free from the unit
and closer to the transmitters. They can be placed anywhere within the
recommended cable length, creating a much wider radio reception range and
further reducing the possibility of signal dropout. When remote-mounted
antennas are desirable, please ask your Shure dealer for information on the
UA830 In-Line RF Amplifier. Cables are available in UA825 (7.5 m [25 ft])
and UA850 (15 m [50 ft]) versions.

CONNECTING RECEIVERS

1.

Using low-loss, 50
right and left (Channels 1 through 4, A and B) RF OUTPUT ports on the
UA845 to the corresponding left and right antenna inputs on each
receiver. Use the CASCADE ports to connect a fifth receiver.

2. Using the supplied power cable, connect the UA845 to a power outlet.

3. To daisy-chain UR4 Receivers together with Power OUTPUT cables,
connect the Power OUTPUT connector of the UA845 to the Power
INPUT connector of one receiver. Connect the remaining receivers
similarly. Connect the POWER INPUT of the unit to a power supply.

NOTE: No more than five (5) Shure UHF receivers should be powered
through a daisy-chain from a single UA845.

 coaxial cables (RG-58 or equivalent), connect the

MULTIPLE UA845 SETUP

1. Connect the CASCADE ports (connector 5) for RF OUTPUT Channels A
and B of one UA845 to the ANTENNA INPUT, channels A and B, of a
UR4 receiver, or a second UA845.

2. If desired, connect additional units in the same manner.

3. To daisy-chain UR4 Receivers together with Power OUTPUT cables, con­nect the Power OUTPUT connector of the UA845 to the Power INPUT
connector of one receiver. Connect the remaining receivers similarly.
Connect the POWER INPUT of the unit to an AC power supply.

WARNING: When adding additional UA845's to a system, each
UA845 should be connected to a separate power supply.

than five (5) receivers can be powered from a single UA845.

Daisy-chaining multiple UA845's through the Power OUTPUT
ports will overload a single power supply, possibly causing damage
to the equipment.
