[. . . ] However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: · Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Shielded cables and I/O cords must be used for this equipment to comply with the relevant FCC regulations. Changes or modifications not expressly approved in writing by AKG Acoustics may void the user's authority to operate this equipment. [. . . ] all unused outputs are electrically terminated automatically. ANTENNA B OUT TO SR: The four BNC connectors 1B through 4B deliver the antenna signals for the B inputs of up to four SR 4000 diversity receivers. all unused outputs are electrically terminated automatically. In addition to the antenna signals, outputs 1A through 4A and 1B through 4B provide a 12 VDC supply voltage for the connected SR 4000 receivers. The only way to ensure that outputs 1A through 4B will provide sufficient current to power the connected receivers is to connect the antenna splitter to an optional PSU 4000 central power supply. If you power the PS 3 F-LOCK antenna splitter from its standard power supply, make sure to power each receiver from its own standard power supply, too. If you connect receivers to the antenna splitter without connecting each receiver to a power supply and AC power, the antenna splitter's standard power supply may be damaged due to overload. LINK A TO PS, LINK B TO PS: These two BNC outputs carry the RF signal of the two antennas A and B. You can connect the LINK outputs to the antenna inputs of another PS 3 F-LOCK antenna splitter to daisy-chain several antenna splitters. Note that you will need one optional PSU 4000 central power supply each to power three PS 3 F-LOCK antenna splitters. The PSU 4000 central power supply delivers a 12 VDC, 2 A secondary voltage for powering three PS 3 F-LOCK antenna splitters and the receivers (12 max. Be sure to keep the remaining screws (5) for later use. The following hints on placing antennas apply to both single-channel and multichannel systems with any number of channels. Reflections off metal parts, walls, ceilings, etc. Place the antennas near the performance area (stage). Make sure, though, that the transmitter will never get any closer to the antennas than 16 ft. Place the two antennas at least 8 inches. There should always be a direct line of sight between the transmitter and antennas. 5 m) away from any equipment that may emit RF radiation such as lighting racks, fluorescent lamps, digital effects units, or PCs. If you set up two antennas side by side (e. , for diversity reception), check that the two antennas are spaced at least 20 cm (8 in. When mounting the antennas on floor stands, be sure to proceed as follows: 1. [. . . ] Connecting the antenna splitter to power first may cause damage to the antenna splitter power supply due to the load presented by the receivers. Do not operate two or more wireless channels on the same frequency at the same time and location. This would cause unwanted noise due to radio interference. To prevent damage from overloading the antenna splitter power supply, always switch power to the various components of your system on and off in the order described in sections 4. [. . . ]
