DO NOT expose the apparatus to dripping and splashing. DO NOT put objects filled with liquids, such as vases, on the apparatus. 16. The MAINS plug or an appliance coupler shall remain readily operable. 17. The airborne noise of the Apparatus does not exceed 70dB (A). 18. Apparatus with CLASS I construction shall be connected to a MAINS socket outlet with a protective earthing connection. 19. To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture. 20. Do not attempt to modify this product. Doing so could result in personal injury and/or product failure. This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit. This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit. WARNING: This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm.

7 Description Benefits Reduction of intermodulation artifacts for cleaner RF environment and more channels on air Simplified antenna placement Shure antenna combiners actively combine antenna outputs from PSM wireless transmitters to a single antenna, improving RF performance and reducing rack clutter. Four DC power outlets and supplied power cables allow you to connect additional PSM systems, without adding external power supplies. Power Turn power off before installing. Use the supplied power cable to connect the unit to an AC power source. The power LED illuminates when powered on. Power the unit off when not in use or before disconnecting the unit from the AC power source PA421A PSM Antenna Combiner MHz A IN INPUT SIGNAL A+B OUT B IN POWER DC OUTPUT EXPANSION PORT MAIN OUT - 50 OHMS Using the Antenna Combiner to Power Transmitters LEDs on the front panel indicate current draw for each PA421A DC output: PSM PSM Antenna Antenna Combiner Combiner MHz MHz The combiner supplies 15 V at up to 660 ma to each DC output.
