MODEL UA845 ANTENNA DISTRIBUTION SYSTEM
UA845
UHF Antenna Distribution System
power
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 U4 or Shure UC4 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 and UC 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

SYSTEM INSTALLATION
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 front- or remote-mounted.
1. Insert the bulkhead adapters through the holes in each bracket,
and secure them from each side, using the supplied hardware.
INSERTING BULKHEAD ADAPTERS
FIGURE 3
2. Connect the supplied antenna cables to the receiver antenna
inputs and adapters.
Mounting the UA845 in an Equipment Rack
NOTE: If front mounting the antennas, connect them before
mounting the UA845 in the rack. Once in the rack, it is more
difficult to insert the bulkhead adapters and connect the
antenna cables.
1. Insert the unit into a 19-inch equipment rack.
2. Using the screws supplied, secure the unit to the rack.

RACK MOUNTING

3. If the antennas are remote mounted from the back of the rack,
insert the supplied plastic plugs into the holes on the front of the
brackets.
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.

3. Install the antennas onto the bulkhead adapters protruding
through the front panel. See 5.

ATTACH ANTENNAS TO THE ADAPTERS
FIGURE 5
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.

Channels A and B of one UA845 to the ANTENNA INPUT,
channels A and B, of a U4 receiver, a UC4 receiver, or a second UA845.
2. If desired, connect additional units in the same manner.
3. To daisy-chain U4 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. No more 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.
4. To power Shure UC4 receivers, connect the power input ports of
the UC4 receivers to the 12 Vdc OUT of the UA845. Up to four
UC4 Receivers can be powered.
