A 25 V amplified output drives corresponding speakers in a distributed sound system. Audio levels that could clip the output are compressed using two dynamic time constants designed to preserve aural transparency, while normal levels pass unaffected so the compressor does not increase feedback potential during paging. It is powered from a 24 Vdc supply such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24kx\"\u003eRDL PS-24KX 24 Vdc 1 A power supply\u003c\/a\u003e, and FLAT-PAK modules can be rack mounted with the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-fp-hra\"\u003eRDL FP-HRA\u003c\/a\u003e or the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-fp-rra\"\u003eFP-RRA rack adapter\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20 W at 25 V\u003c\/strong\u003e — The amplifier delivers 20 W RMS on a 25 V constant-voltage output.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntegral compressor\u003c\/strong\u003e — Built-in compression controls clipping and maximizes average level.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible line input\u003c\/strong\u003e — The input accepts +4 dBu balanced or -10 dBV unbalanced signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFront-panel gain\u003c\/strong\u003e — Gain can be adjusted by hand or with a trimming screwdriver.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug-in terminal blocks\u003c\/strong\u003e — Input and output connect through plug-in terminal blocks for simple installation.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025744916716,"sku":"FP-PA20B","price":211.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/fp-pa20b.jpg?v=1793583133","url":"https:\/\/creationnetworks.net\/products\/rdl-fp-pa20b","provider":"Creation Networks","version":"1.0","type":"link"}
