User manual ELECTRO-VOICE E-V 11 DATASHEET

[. . . ] Power out jacks and cables are provided to supply up to four receivers thus eliminating excess power supply clutter. Rack panel mounting "ears" allow the E-V 11 to be mounted in a standard 19 inch equipment rack. "Knock outs" in the ears allow front connection of antenna cables. -1- System Configuration Figure 2 illustrates the typical system configuration using the E-V 11. [. . . ] By connecting one of the outputs of the first splitter to the antenna inputs of the second splitter, three additional receivers may be driven by a single pair of antennas. SPECIAL NOTE: In any system, unused splitter outputs should be terminated with a 50 ohm "dummy load".

For best results, use a pair of LPA-500 directional log periodic antennas. The LPA-500 offers the best performance and broadest bandwidth available. Good results may be obtained with optional CLA or FA-500 1/2 wave antennas. The 1/4-wave antennas that are supplied with EV wireless systems will provide adequate performance in some situations. The 1/4-wave antennas should be oriented as shown in Figure 5. Do not use 1/4-wave an ten nas for re mote mounting.

See the accessories section of this manual for special low loss cable assemblies. REMOVE PLUG Figure 6 Antenna Connectors -5- 12 Volt Power On "Antenna In" Jacks To power UAA-500 in-line antenna amplifiers, 12 volt power is available on the center pin of the antenna in jacks. This power is disabled when the UAD4 leaves the factory but may be turned on by the installer. To turn on the 12 volts, first take off the cover of the split ter by re mov ing the screws. The Jumper is installed on one pin of the header at the fac tory. To turn on power, un plug the jumper and install it on both pins of the header. CAUTION: Do not attach antennas and splitters with a DC short circuit to the antenna in jacks when the power is turned on. Damage could result to the splitter or other devices. The following antennas and accessories may be used with power on: FA-1, CLA-X, LPA-500B, and UAA-500. The following antennas and accessories may be used with the power off: FA-1, CLA-X, and LPA-500.
