System Installation - Shure UA845 Mode D'emploi

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.

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. See 5.

ATTACH ANTENNAS TO THE ADAPTERS
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.

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.

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 rec-
ommended cable length, creating a much wider radio reception range and
further reducing the possibility of signal dropout. When remote-mounted an-
tennas 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.
