It works alone as a noise gate or with other RDL modules to build automatic mixing systems.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/st-gla1.jpg\" alt=\"RDL ST-GLA1 Gated Line Amplifier and Noise Gate\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eThe ST-GLA1 opens when the input signal exceeds an adjustable threshold, switching in 10 ms with a nominal 2-second off delay that can be extended with an external capacitor. Gain and threshold are adjustable, and two LED indicators assist setup. The input (500 Ω balanced or 5 kΩ unbalanced) and the +4 dBu, 150 Ω balanced output may be wired balanced or unbalanced. An open-collector slave output rated at 50 mA can trigger other equipment or RDL modules. The module requires ground-referenced 24 Vdc at 75 mA, such as from the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-ps-24ax\"\u003eRDL PS-24AX\u003c\/a\u003e.\u003c\/p\u003e\u003ch2\u003eWhat are the key features?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelf-gating noise reduction\u003c\/strong\u003e — The output switches off when no signal is present to suppress accumulated noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable gain and threshold\u003c\/strong\u003e — Front controls set level and gating sensitivity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFast, silent switching\u003c\/strong\u003e — The gate opens in 10 ms without clicks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen-collector logic output\u003c\/strong\u003e — A slave output triggers other equipment when the gate opens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced or unbalanced I\/O\u003c\/strong\u003e — Input and output wire balanced or unbalanced.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":68025746063596,"sku":"ST-GLA1","price":177.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/st-gla1.jpg?v=1793583135","url":"https:\/\/creationnetworks.net\/products\/rdl-st-gla1","provider":"Creation Networks","version":"1.0","type":"link"}
