Each studio-quality preamplifier can be set to automatic gain, fixed 40 dB or fixed 60 dB, and routed to Format-A pair A, B or C. The wall-mount module is powered remotely through its RJ45 connection and fits RDL WB-1U and WB-2U boxes or standard US electrical boxes.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/ds-tpsm2a.jpg\" alt=\"RDL DS-TPSM2A Format-A dual microphone preamplifier sender, stainless steel\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe DS-TPSM2A sends two microphone signals over a single twisted pair cable to RDL Format-A receivers and distributors. Both XLR inputs provide IEC 48 V phantom power and accept dynamic or condenser microphones. In AUTO mode the module sets 60 dB of gain for dynamic microphones and 40 dB for condenser microphones; installers can lock gain to HIGH or LOW instead. A rear-panel switch for each preamplifier assigns its output to Format-A pair A, B or C. Because it uses only two pairs, a single-pair Format-A sender such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-tps1a\"\u003eRDL D-TPS1A\u003c\/a\u003e can be daisy-chained through the second RJ45 jack, provided each source feeds a different pair. Power and all three audio pairs pass through both rear-panel RJ45 jacks. The module is powered through the cable from another module, a distributor such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-tpda\"\u003eRDL RU-TPDA\u003c\/a\u003e, or a power inserter like the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ru-tp4pw\"\u003eRDL RU-TP4PW\u003c\/a\u003e. RDL lists the PS-24AS (USA) or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003ePS-24AX\u003c\/a\u003e (international) as the recommended supply for the system.
