5English –APPENDIX B. RACK MOUNTING OPTIONSRack Mounting the PA Antenna CombinerNOTE: Dual mounting with other Shure products. The PA AntennaCombiner can also be dual mounted with a Shure SC or LX half-rackwireless receiver. These same instructions apply, but the front panels willnot align evenly. The SC and LX receivers must use the SC and LX rackears. They cannot be mounted with PA Antenna Combiner rack ears.However, the link bars are universal and can be used to connect the PAAntenna Combiner with an LX or SC receiver.WARNING: Do not torque the screws too tightly, or the chassis may be dam-aged.Single Unit1. 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.Dual-Mounted Units1. 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 eachunit. The units are designed so that the link bar on the right unit will fit directly on topof the link bar of the left unit (facing front). Use two of the screws and washers fromstep 1 per link bar to fasten the link bars.3. Align the rackmount brackets on the outside panels of the units and fasten using fourof the screws and washers from step 1.NOTE: The link bars are designed with recesses in the side holes where thescrew 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 twounthreaded holes. In order to ensure proper fit, stack the link bars so thatthe unthreaded holes on one bar align with the threaded holes on the otherbar. Then, each pair of screws fits in the opposite direction of the other pair,ensuring the stability of the link.4. Place the two units next to each other so the link bars overlap and the screw holeson the two align.5. Fasten the link bars together using 4 supplied screws and washers.
6English –Mounting in an Equipment RackSINGLE MOUNT DUAL MOUNT1. 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 AntennaThe PA Antenna Combiner comes equipped so the antenna can be front-mounted.Front-mounting prevents antenna cables from becoming entangled and greatly minimizesRF interference from other cables. When a unit is located in a rack, antennas should beeither front- or remote-mounted.1. Insert the bulkhead adapter through the hole of either mounting bracket, and secureit from the front and the back using the supplied hardware.2. Connect the supplied antenna cable to the combiner antenna output and bulkheadadapter.3. Install the antenna on the bulkhead adapter.NOTE: The antenna which comes supplied with the PSM Transmitter canbe remote mounted. For remote mounted installations, however, werecommend using the PA705 UHF Directional Antenna.
