Serv icing is re quired when the apparatus has been damaged in any way, such as power-supply cord or plug is dam- aged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to ra in or moisture , does not opera te normally, or has been dropped. 15.DO NOT expose the appara tus to dripping and splashing. DO NOT put objects lled with liquids, such as vases, on the apparatus. 16.The MAINS plug or an appliance coupler shall remain readily opera ble. 17.The airborne noise of the appara tus does not exceed 70dB (A). 18.Apparatus with CLASS I construction shall be connected to a MAINS socket outl et with a protective earthing connection. 19.To reduce the risk of re or electric shock, do not expose this apparatus to rain or moisture. 20.Do not attempt to modify this product. Doi ng so coul d result in personal injury and/or product failure. USE only with a cart, stand, tri pod, bracket, or table speci ed by the manufacture r, or sold with the appara tus. When a cart is used, use caution when moving the cart /appara tus combination to avoid injury from tip-over. This symbol indicates that there are important operating and maintenance instructions in the literature accompanying this unit. This symbol indicates that dangerous voltage constituting a risk of electr ic shock is present within this unit. DESCRIPTION The Shure PA821A Antenna Combiners actively combine antenna outputs from up to eight PSM wireless transmitters to a single antenna, improving RF performance and reducing rack clutter. INSTALLATION Set the power switch on the front panel to OFF before installing. Connect the unit to an AC power source using the supplied power cable. Switch the power ON to use the device. The power light will illuminate. Power the unit OFF when not in use or before disconnecting the unit from the AC power source. 8-TO-1 COMBINING: 1. Using the supplied BNC-BNC cables, connect the Antenna Output of each transmitter to the ANTENNA INPUTS of the PA821A (Figure 2). 2. Attach an antenna to the MAIN Out of PA821A. For wideband applications, use PA805SWB directional antenna (Figure 1). 3. Connect the PA821A to a power outlet using one of the supplied power cables. The PA821A contains a universal power supply to operate anywhere in the world. NOTE: When the PA821A is powered on, the input signal indicators (1-8) on the front panel will illuminate if an active transmitter is con- nected to the corresponding input (1-8) on the back panel (Figure 1). WARNING: Voltages in this equipment are hazardous to life. No user-serv iceable parts inside. Refer all servicing to qualied service personnel. The safety certi cations do not apply when the operating voltage is changed from the f actory setting. WARNING: This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. PSM Transmitters AC POWER FIGURE 2 FIGURE 1 4 FOR MORE THAN 8 TRANSMITTERS 1. Using the supplied BNC-BNC cables, connect the Antenna Output of each transmitter to the Antenna Inputs of the PA821A. 2. Use the 1 ft. jumper BNC-BNC cable to connect the MAIN Output of the PA821A to the A IN of the Expansion Port. 3. Connect another Antenna Output (from a ninth PSM transmitter, second PA821A or other antenna port) to the B IN of the Expansion Port. 4. Attach an antenna to the A + B OUT of the Expansion Port. For wideband applications, use the PA805-SWB directional antenna, Figure 3. FIGURE 3 FURNISHED ACCESSORIES (8) 2 ft.

Maximum Permissible Exposure calculations The MPE distance will be calculated for the worst case of a 100% transmitter duty cycle. For an isotropic radiator the surface area of a sphere can be used to determine the area over which the transceiver energy is radiated. Surface area of a sphere = 4 * π * radius2 In the case where there is an antenna gain, the worst case energy density is increased by the antenna gain. In this case, the exposure level for a controlled environment can be calculated as follows: MPE distance =((output power*duty cycle*10*(antenna gain/10))/(4* π*Exposure Limit [mW/cm2]))1/2 In the case of 14 dBi HA8089 antenna MPE distance = ((100 mW * 1 * 25.1) /( 4 * 3.14 * 1)) 1/2 = 22.7 cm In the case of 6.5 dBi shark fin antenna MPE distance = ((100 mW * 1 * 4.5) /( 4 * 3.14 * 1)) 1/2 = 9.6 cm

27A17060 (Rev. 1)Printed in U.S.A. ©2011 Shure Incorporated PA421A, PA821A Antenna Combiner Addendum Federal Communications Commission RF Exposure Notice: Antennas used for the purpose of radiating signals are limited to a maximum gain of 14 dBi. Each antenna must be po- sitioned to observe minimum separation requirements from all users and bystanders. The following guidelines should be used when considering separation distances. Antennas must be placed such that, under normal conditions, personnel cannot come within 72 cm (~2.5 ft.) from any antenna. Adhering to this minimum separation will ensure that the employee or bystander cannot exceed RF exposures beyond the maximum permissible limit as defined by 47 CFR 1.1310, i.e., limits for General Population/Uncontrolled Exposure.
