User manual AKG PS 3 F-LOCK QUICK START GUIDE

[. . . ] 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. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. [. . . ] If you use cable ducts, be sure to use separate ducts for the audio lines. The PS 3 F-LOCK rear panel provides the following inputs and outputs: DC IN 12 V/2A: Input jack for the standard power supply or optional PSU 4000 central power supply. aNTENNA A IN , ANTENNA B IN: BNC input connectors for SRA 1 , SRA 2 B , or RA 4000 B remote antennas. Since the SR 4000 is a diversity receiver you will need two receiving antennas (optional). each antenna input provides a 12 VDC supply voltage for an active antenna. ANTENNA A OUT TO SR: The four BNC connectors 1A through 4A deliver the antenna signals for the A inputs of up to four SR 4000 diversity receivers. 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. 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. Screw a short bracket (6) to the outer side panel of each antenna splitter using for each bracket two of the screws (2) you removed from the antenna splitter side panels. The following hints on placing antennas apply to both single-channel and multichannel systems with any number of channels. Make sure, though, that the transmitter will never get any closer to the antennas than 16 ft. 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. , 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. Pull the boom out all the way to one side to make sure the antenna will be at least 28 inches (70 cm) away from the stand. Do not allow the cable to sag below the boom because this may degrade the reception quality. If you mount your antennas on a wall or ceiling, be sure to keep the following minimum distances: 1. ) from any walls or other plane surfaces, metal grids, or metal scaffolding. [. . . ] Referring to Table 1, connect each antenna to one or two AB 4000 antenna boosters (if necessary), an ASU 4000 remote power adapter, and to the appropriate antenna input on the SR 4000 receiver. Check that the AC mains voltage stated on the power supplies for the two ASU 4000s and the receiver is identical to the AC mains voltage available where you will use your system. Using the power supplies with a different AC voltage may cause damage to the unit. Connect the remote power adapters and the receiver to their respective power supplies and connect each power supply to a convenient power outlet. [. . . ]
