INTRODUCTION

Shure PA-Series UHF Antenna Combiners are designed to allow up to four PSM

wireless transmitters to use a single antenna. The unit combines four PSM wireless

transmitters to a single antenna, reducing stage clutter and improving intermodulation

distortion performance.

Features

UHF operation.

Up to four wireless transmitters can be combined

into one transmitting antenna.

Low noise and intermodulation distortion. The PA

Antenna Combiner maintains clean signals with

minimal distortion.

Microstrip technology for signal combining and

filtering.

Four push/pull amplifiers for improved linear

performance.

Front-mounted antenna. The PA Antenna

Combiner comes with hardware to front-mount the

antenna, which allows for better radio

transmission.

Dual rackmount hardware. The PA Antenna

Combiner comes with hardware so that it can be

rackmounted with another PA Antenna Combiner

or PSM Transmitter into a single rack space.

INSTALLATION

Connection

1. Using the cables supplied with each PSM Transmitter, connect the ANTENNA OUT

of each PSM Transmitter to the INPUTS of the PA Antenna Combiner.

2. Attach the antenna (one supplied with each PSM Transmitter), or an optional

directional antenna such as the Shure Model PA705, to the ANTENNA OUT

connector of the PA Antenna Combiner.

3. Run the supplied power cable from the power connector to a power supply.

APPENDIX B. RACK MOUNTING OPTIONS

Rack Mounting the PA Antenna Combiner

NOTE: Dual mounting with other Shure products. The PA Antenna

Combiner can also be dual mounted with a Shure SC or LX half-rack

wireless receiver. These same instructions apply, but the front panels will

not align evenly. The SC and LX receivers must use the SC and LX rack

ears. They cannot be mounted with PA Antenna Combiner rack ears.

However, the link bars are universal and can be used to connect the PA

Antenna Combiner with an LX or SC receiver.

WARNING: Do not torque the screws too tightly, or the chassis may be dam-

aged.

1. Remove the screws and washers from each side of the unit.

2. Align the supplied rackmount brackets over the holes.

3. Using the screws and washers from step 1, fasten the rackmount brackets.

1. Remove the screws and washers on each side of both units.

2. Placing the two units side-by-side, screw the link bars to the inside panels of each

unit. The units are designed so that the link bar on the right unit will fit directly on top

of the link bar of the left unit (facing front). Use two of the screws and washers from

step 1 per link bar to fasten the link bars.

3. Align the rackmount brackets on the outside panels of the units and fasten using four

of the screws and washers from step 1.

NOTE: Thelinkbarsaredesignedwithrecessesinthesideholeswherethe

screw head and washer fit in. Once the link bars are screwed on properly,

the vertical holes will align. Each link bar has two threaded holes and two

unthreaded holes. In order to ensure proper fit, stack the link bars so that

the unthreaded holes on one bar align with the threaded holeson the other

bar. Then, each pair of screws fits in the opposite direction of theother pair,

ensuring the stability of the link.

4. Place the two units next to each other so the link bars overlap and the screw holes

on the two align.

5. Fasten the link bars together using 4 supplied screws and washers.

1. Insert the unit(s) into a 19-inch equipment rack.

2. Fasten the unit(s) to the rack using all four of the supplied screws.

Front Mounting the Antenna

The PA Antenna Combiner comes equipped so the antenna can be front-mounted.

Front-mounting prevents antenna cables from becoming entangled and greatly minimizes

RF interference from other cables. When a unit is located in a rack, antennas should be

either front- or remote-mounted.

1. Insert the bulkhead adapter through the hole of either mounting bracket, and secure

it from the front and the back using the supplied hardware.
