Its split-band AGC maintains a steady -10 dBV output for input variations as great as 25 dB while staying nearly transparent to listeners. RCA phono inputs and outputs and a compact RDL FLAT-PAK chassis make it easy to add to background or foreground music systems.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/fp-alc2.jpg\" alt=\"RDL FP-ALC2 stereo automatic level control FLAT-PAK\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe FP-ALC2 is a dual-channel module with unbalanced phono jack inputs and outputs at -10 dBV nominal. The automatic level range spans -30 to 0 dBV, so changers, satellite receivers and other variable sources arrive at the same level. Self-adjusting attack and release times keep processing nearly transparent for program material from rock to classical. A gate at -40 dBV prevents level seeking during quiet passages. Setup uses one gain adjustment: set it as high as possible with the loudest source without the INPUT OVERLOAD indicator flashing. Power is 24 Vdc at 80 mA, ground-referenced, through the barrier block or a dc power jack. The low-profile case fits confined spaces and can be rack mounted with 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 adapters.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStereo AGC\u003c\/strong\u003e — Holds a consistent -10 dBV output from variable consumer sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide correction range\u003c\/strong\u003e — Handles input variations as great as 25 dB.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSplit-band processing\u003c\/strong\u003e — Keeps level control nearly transparent across music styles.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGated control\u003c\/strong\u003e — Avoids level seeking during silence.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRCA connections\u003c\/strong\u003e — Unbalanced phono jack inputs and outputs for consumer equipment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFLAT-PAK chassis\u003c\/strong\u003e — Low-profile metal case for confined spaces.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is it typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCommercial meeting space\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003cli\u003eTraining room\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-ALC2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eInputs (2)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e10 kΩ unbalanced phono jack\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 Level\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e-10 dBV (nominal)\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 (2)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e200 Ω unbalanced phono jack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eOutput Level\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e-10 dBV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eAutomatic Level Range\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e-30 to 0 dBV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eGate Threshold\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e-40 dBV (20 Hz to 3 kHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eFrequency Response (excluding AGC)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e20 Hz to 20 kHz (± 0.5 dB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eTHD+N\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e\u0026lt;
