Front-panel gain adjustment and a 1 V signal indicator make it easy to set correct levels over long cable runs. Its 1\/3-rack RACK-UP format allows high-density rack mounting.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ru-vda4.jpg\" alt=\"RDL RU-VDA4B NTSC\/PAL 1x4 Video Distribution Amplifier, BNC\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eVideo inputs and outputs are made on front-panel BNC jacks, and power connects through full-size barrier block terminals on the rear panel. The input stage has two jacks: one for the incoming signal and a LOOP OUT that passes the source signal on to other equipment. The input is bridging, so if 75 Ω termination is required, the terminator plugs onto the LOOP OUT jack. Four amplified outputs each deliver 1 V p-p into 75 Ω. A front-panel GAIN potentiometer adjusts gain from -1 dB to +7 dB (0.9 to 2.25 V p-p), helping compensate for cable loss. Frequency response is 10 Hz to 10 MHz (±0.2 dB), with differential gain and phase of 0.1% and 0.1 degree and output isolation greater than 40 dB. The module runs from ground-referenced 24 Vdc at 60 mA; RDL recommends the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX\u003c\/a\u003e (international), not included.
