A selector chooses Format-A Pair A, B or C, and a loop-through jack passes all three pairs to other amplifiers or receivers. It is plenum rated per UL 2043 and ships with its 48 Vdc power supply.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/08\/SF-PA100A-1024x629.png\" alt=\"RDL SF-PA100A Format-A amplifier\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe SF-PA100A receives three audio channels on an RJ45 Format-A connector and feeds the selected pair to the amplifier. At the normal gain setting it delivers 100 W for an audio level of +22 dBu. The three Format-A pairs feed through to the LOOP OUT jack for additional amplifiers or Format-A receivers. Input gain is set with a rear-panel potentiometer and a dual-LED VU meter calibrated 10 dB below maximum output. An internal VCA sets the output level, and the REMOTE CONTROL RJ45 jack accepts an RDL D-RLC10KM-type remote, an external 10 kΩ potentiometer or 0 to 10 Vdc. A selectable compressor adds up to 15 dB of headroom to the amplifier input using automatically adjusting attack and release. The Class D output stage runs cool and includes thermal and short-circuit protection. The included supply accepts 100 to 240 Vac and provides 48 Vdc. Format-A sources include Dante interfaces such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-nfd\"\u003eRDL RU-NFD\u003c\/a\u003e and wall-plate senders such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ds-tps2a\"\u003eRDL DS-TPS2A\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e100 W constant voltage\u003c\/strong\u003e — Drives 70 V or 100 V speaker lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFormat-A input\u003c\/strong\u003e — Selects Pair A, B or C from an RJ45 Format-A connection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoop-through output\u003c\/strong\u003e — Passes all three pairs to other amplifiers or receivers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable compressor\u003c\/strong\u003e — Adds up to 15 dB of headroom to the amplifier input.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVCA remote control\u003c\/strong\u003e — RJ45 remote jack for RDL remotes, a 10 kΩ pot or 0 to 10 Vdc.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlenum rated\u003c\/strong\u003e — UL 2043 rated with an included 48 Vdc power supply.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is it typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommercial paging and background music zones\u003c\/li\u003e\n\u003cli\u003eHouses of worship\u003c\/li\u003e\n\u003cli\u003eTraining rooms and classrooms\u003c\/li\u003e\n\u003cli\u003eGovernment facilities\u003c\/li\u003e\n\u003cli\u003eMulti-purpose rooms\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"\u003e\u003ctable border=\"1\" cellpadding=\"6\" style=\"border-collapse:collapse;width:100%;min-width:300px;table-layout:fixed;border-color:#ddd\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:44%\"\u003e\n\u003ccol style=\"width:56%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctr\u003e\u003ctd colspan=\"2\" bgcolor=\"#f5f5f5\"\u003e\u003cstrong\u003eFormat-A Input Section\u003c\/strong\u003e\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRDL TP Format-A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eInput Connection\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRJ45\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eFormat-A Signal Pairs Used (3)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eA, B, or C (3-position selector)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eFormat-A Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRJ45 (loop-through)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd valign=\"top\"\u003e\u003cstrong\u003eCMRR\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;
