User manual AKG PS 4000

[. . . ] Before connecting the equipment to power, check that the AC mains voltage stated on the supplied power supply is identical to the AC mains voltage available where you will use the equipment. Using adapters with an AC output and/or a different output voltage may cause serious damage to the equipment. If any solid object or liquid penetrates into the equipment, shut down the sound system immediately. Disconnect the power supply from the power outlet immediately and have the equipment checked by AKG service personnel. [. . . ] Note that you will need one optional PSU 4000 central power supply each to power three PS 4000 antenna splitters. The PSU 4000 central power supply delivers a 12 VDC, 2 A secondary voltage for powering three PS 4000 antenna splitters and the receivers (12 max. the active antennas are powered by the PS 4000 antenna splitter via the antenna cables. For complex systems with long antenna cables, we recommend powering each active antenna from a PSU 4000 central power supply via an ASU 4000 remote power adapter. The SRA1 will even operate perfectly as close to the floor or ceiling as 15 cm (6 in. The SRA 2 B is an active directional antenna with a rugged, water-resistant case designed specifically for indoor and outdoor use at a distance from the performance area. Using RG213 antenna cables and two AB 4000 antenna boosters in series, you can set up the SRA 2 B even 200 m (660 ft. An optional laser pointer makes it easy to align the antenna precisely with the performance area. The RA 4000 B is an active omnidirectional antenna with a rugged, water-resistant case designed specifically for indoor and outdoor use in close proximity to the performance area. Using RG213 antenna cables and two AB 4000 antenna boosters in series, you can set up the SRA 2 B even 200 m (660 ft. Unscrew the four rubber feet (1) from the antenna splitter bottom panel. Use the fixing screws (2) to screw the short bracket (3) to one side panel and the long bracket (4) to the other side panel. Unscrew the four rubber feet (1) from each antenna splitter's bottom panel and remove the screws (5) from the rubber feet (1). Unscrew the two fixing screws (2) from the right-hand side panel of one antenna splitter and from the left-hand side panel of the other antenna splitter. Remove the plastic covers (3) from the side panels with the fixing screws (2) still on. Insert one connecting strip (4) into each free slot in the side panel of the first antenna splitter, making sure to align the hole in each connecting strip (4) with the appropriate threaded hole in the antenna splitter bottom panel. Fix the two connecting strips (4) on the first antenna splitter using two of the screws (5) you removed from the rubber feet. To join the two antenna splitters, slide the connecting strips (4) on the first antenna splitter through the free slots in the side panel of the second antenna splitter. Make sure to align the hole in each connecting strip (4) with the appropriate threaded hole in the bottom panel of the second antenna splitter. Fix the two connecting strips (4) on the second antenna splitter using two of the screws (5) you removed from the rubber feet. 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. [. . . ] Power supply of receiver or feeder cable from PSU 4000 to receiver a) makes poor contact or b) is defective. Transmitter and receiver of dead channel are tuned to different frequencies. A) Check power supply or feeder cable connectors for secure fit or b) Replace power supply or feeder cable. Refer to Table 1 to check cable lengths nents too low because cable run is too and use shorter cables or break down long. [. . . ]
