Below is the Audio Technica product description for these distribution amplifiers.
Features • Active unity-gain, band filtered DA • Dual 1-in 4-out RF sections • RF cascade output • Defeatable 12V DC antenna power • Four receiver power jacks (12V DC, 500 mA ea.) • IEC power input with pass-through connector • Reinforced metal chassis with integral rack ears and rear rack support • Front-mount antenna cables and connectors included Description The AEW-DA550C (540-565 MHz) and AEW-DA660D (655-680 MHz) are UHF active unity-gain antenna distribution systems that enable a single pair of antennas to feed multiple wireless system receivers. Identical in all other respects, the AEW-DA550C operates over a nominal 540-565 MHz range, while the AEW-DA660D operates over a nominal 655-680 MHz range. These units are designed to complement wireless systems operating in the Audio-Technica “C” Band (541.500 - 566.375 MHz) or “D” Band (655.500 -680.375 MHz), as well as other wireless systems operating in the same frequency ranges. Each antenna distribution system provides two identical “1-in, 4-out” RF sections consisting of an antenna input, four bandpassed isolated receiver outputs and a bandpassed “cascade” directional coupler to supply signal to additional equipment. All RF connections utilize standard BNC-type connectors. Both antenna input jacks offer switchable +12V DC output on their center pins to operate Audio-Technica powered antennas, in-line boosters or other powered antenna accessories drawing up to 250 mA total per antenna jack. Additionally, four jacks providing 12V DC (center positive) are provided on the rear panel of each antenna distribution system to power as many as four wireless receivers operating on 12 volts at up to 500 mA each. The 12-volt supplies for powering receivers and in-line devices are shortcircuit protected. Included with the antenna distribution system are four DC cables appropriate for use with ATW-R3100b (or like powered) receivers along with ten RF jumper cables. The antenna distribution system operates from 100-240V AC 50/60 Hz power and features an IEC-type input connector with pass-through to allow for powering of other devices. Designed to mount in a single rack space, the unit features steel case construction with steel reinforced front panel and rear rack-mount supports for extreme durability. An included set of RF bulkhead connectors and cables permits front-panel antenna mounting.
