Each channel is identical. The audio inputs are bridged at 20 kΩ and accept either an unbalanced or a balanced audio signal. Gain is adjustable from unity to +24 dB using a 25-turn precision audio taper trimming potentiometer. The output line driver circuits are designed to drive long balanced audio lines into 600 Ω loads.\u003cbr\u003e\u003cbr\u003eThe STA-2A features wideband circuitry for excellent phase response low noise low distortion and exceptional audio clarity. RDL's SupplyFlex power input configuration is included in the STA-2A. The power supply input may be fed from a floating (not ground-referenced) 24 Vdc power source from a bipolar power supply (+\/- 12 Vdc or +\/-15 Vdc) or from a ground-referenced 24 Vdc power supply.\u003cbr\u003e\u003cbr\u003eMany audio products provide optimum performance when feeding into a bridging input but may not provide the output needed to directly drive low-impedance lines terminated with 600 Ω transformers. The STA-2A is specifically designed for such installations and is also ideal in installations requiring high gain in line-level audio transmission.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e• Up to 24 dB Gain in Audio Lines\u003cbr\u003e• Conversion between Unbalanced and Balanced\u003cbr\u003e• Conversion between High and Low Impedance\u003cbr\u003e• Low-Impedance High-Current Line Drivers\u003cbr\u003e• Dual-Channel Line-Level Preamplifiers\u003cbr\u003e• High Gain High Output High Performance\u003cbr\u003e• RDL® SupplyFlex™ Power Input Configuration\u003cbr\u003e\u003cbr\u003e7 Year Warranty\u003c\/p\u003e\u003ctable class=\"features\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003cth colspan=\"2\"\u003eFeatures\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\u003ctr\u003e\n\u003ctd class=\"feature\"\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003e7 Years  \u003c\/td\u003e\n\u003c\/tr\u003e\u003c\/tbody\u003e\n\u003c\/table\u003e","brand":"Radio Design Labs","offers":[{"title":"Default Title","offer_id":63661023002954,"sku":"RDLSTA2A","price":253.89,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0989\/6896\/1354\/files\/RDLSTA2A-1.jpg?v=1791028197","url":"https:\/\/crystaltechgroup.myshopify.com\/products\/rdlsta2a-dual-high-gain-line-amplifiers-7-year-warranty","provider":"Crystal Tech","version":"1.0","type":"link"}
