MODEL UA845 ANTENNA DISTRIBUTION SYSTEM

English

The Shure Model UA845 is an amplified, UHF Antenna Distribution

System designed to expand 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. CAS-

CADE 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:

✓

UA845 Antenna Distribution System

✓

Rack-mounting hardware

✓

Surface-mounting hardware

✓

Front-mounting antenna hardware

✓

18-in. Power OUTPUT Cord

SYSTEM FEATURES

•

•

• Expandability. The UA845 UHF Antenna Distribution System is designed for large UHF wireless systems. Each unit allows up to four wireless receivers to use the same two antennas, and the CASCADE ports allow connection to a fifth receiver or a second UA845.

Compatibility. The UA845 is compatible with all Shure wireless microphone receivers operating within a compatible frequency range (see UHF Carrier Frequency Ranges in the

Specifications section).

CASCADE Ports. Two 50 W, BNC-type antenna CASCADE ports allow an additonal UA845 unit or a fifth wireless receiver. A large wireless system can be run off of a single pair of antennas.

✓

Power Cord

✓

Antenna cables for receiver connections

✓

DC power cables for receiver connections to DC power connectors on UC receivers.

The Shure Model UA845 has been developed to ensure 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

Locate multiple transmitters more than 3 m [10 ft] from receiving antennas

•

•

•

•

Power OUTPUT and OUT Connectors. Up to five (5) U4 receivers can be daisy-chained and powered from a single source via the Power OUTPUT connectors. Up to four (4)

UC4 receivers can be powered from the UA845 using the 12

Vdc OUT connectors.

Low Noise and Intermodulation Distortion. The UA845 maintains clean signals with minimal distortion.

Insertion Loss Compensation. Whenever a signal is split to multiple output ports, there is a loss in signal strength. The

UA845 amplifies signals to compensate, ensuring a strong signal to the receivers.

Front-Mounted Antennas. The UA845 comes with hardware to front-mount the antennas, if desired.

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.

See Figure 3.

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 the antennas are to be front-mounted, Shure recommends connecting them before mounting the UA845 in the rack. Once the

UA845 is 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 (Figure 6).

INSERTING BULKHEAD ADAPTERS

FIGURE 3

2.

Connect the supplied antenna cables to the receiver antenna inputs and adapters. See Figure 4.

RACK MOUNTING

FIGURE 6

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 (Figure 7)

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.

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

CONNECTING RECEIVERS

SINGLE UA845 SETUP (FIGURE 8)

1.

Using low-loss, 50

W coaxial cables (RG-58 or equivalent), connect the right and left (Channels 1 through 4, A and B) RF OUT-

PUT 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 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 a power supply.

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

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.

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 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.
