Bandwidth is flat to 10 MHz, and gain is adjustable from unity to +6 dB from the top panel. The compact FLAT-PAK chassis powers from 24 Vdc and can pass power to additional FLAT-PAK modules.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/fp-vda4.jpg\" alt=\"RDL FP-VDA4 NTSC\/PAL video distribution amplifier\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe FP-VDA4 bridges a 75 Ω video line with a 1 kΩ input, so the source can loop through to another device. One input BNC accepts the signal and a second LOOP OUT jack passes the source on. If the input needs 75 Ω termination, the provided terminator plugs onto the LOOP OUT jack. Four source-terminated outputs deliver 1 V p-p into 75 Ω, and unused outputs need not be terminated. Frequency response is 10 Hz to 10 MHz within ±0.2 dB, with output isolation above 45 dB. A top-panel GAIN potentiometer sets gain from unity to +6 dB. Power is 24 Vdc at 60 mA through a barrier block or dc jack, and a second jack on the other end feeds more FLAT-PAK modules. For rack installation, use RDL FLAT-PAK accessories such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-fp-hra\"\u003eRDL FP-HRA\u003c\/a\u003e or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-fp-rra\"\u003eRDL FP-RRA\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour video outputs\u003c\/strong\u003e — Distributes one composite source to four 75 Ω outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoop-through input\u003c\/strong\u003e — LOOP OUT jack passes the source on, with a terminator provided.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable gain\u003c\/strong\u003e — Unity to +6 dB from the top panel.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide bandwidth\u003c\/strong\u003e — Flat to 10 MHz for NTSC or PAL operation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow differential errors\u003c\/strong\u003e — 0.1% differential gain and 0.1 degree differential phase.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower pass-through\u003c\/strong\u003e — Second dc jack feeds additional FLAT-PAK modules.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is it typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGovernment space\u003c\/li\u003e\n\u003cli\u003eTraining room\u003c\/li\u003e\n\u003cli\u003eBroadcast studio\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room\u003c\/li\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"\u003e\u003ctable style=\"border-collapse:collapse;width:100%;min-width:300px;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:44%\"\u003e\n\u003ccol style=\"width:56%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eFP-VDA4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eInput Impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e1 kΩ (Bridging 75 Ω Line)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eGain\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eUnity to +6 dB (adjustable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eLoad Impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e75 Ω\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eOutputs (5)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e1 LOOP OUT from Input Signal;
