These are often used on a broadcast path to prevent on-air silence should a technical problem occur with audio. Audio connections are stereo analog XLR. There is an input pair for the primary source, and an input pair for the backup source. The SD1 can also be configured as a twin single channel silence detector. Each channel can have the configuration parameters set independently. The threshold at which the unit detects a low level is configurable, as is the amount of reaction and sustain time. A comprehensive set of GPIO allow for triggering external devices when the secondary input has been triggered. Intelligent modes can be set to allow for switching back to the primary audio source once a sustained audio level has returned to original setup.\u003c\/strong\u003e\u003c\/p\u003e\u003c\/div\u003e\u003cdiv class=\"features\"\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStereo or dual mono operation\u003c\/li\u003e\n\u003cli\u003eConfigurable threshold \u0026amp; time settings\u003c\/li\u003e\n\u003cli\u003eGPIO loops for alarm outs or external switching (25 Pin D-type)\u003c\/li\u003e\n\u003cli\u003eSmart fail \u0026amp; smart recovery modes\u003c\/li\u003e\n\u003cli\u003eBypass relays\u003c\/li\u003e\n\u003cli\u003eAnalog inputs: Main L\/R, AUX L\/R\u003c\/li\u003e\n\u003cli\u003eAnalog outputs: Main L\/R\u003c\/li\u003e\n\u003cli\u003eInput impedance: \u0026gt;30kR\u003c\/li\u003e\n\u003cli\u003eOutput impedance: \u0026lt;50R\u003c\/li\u003e\n\u003cli\u003eNoise: -85dBA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eInputs and outputs can accept balanced and unbalanced connections\u003c\/li\u003e\n\u003cli\u003eSilence detection: -60 to -10dB selectable\u003c\/li\u003e\n\u003cli\u003eTiming threshold: 5s to 5min\u003c\/li\u003e\n\u003cli\u003eRecovery time: 5 to 60s\u003c\/li\u003e\n\u003cli\u003eRedundant power connection via PS1 Power Station (DC 4 Pin Neutrik XLR plug ±12V DC)\u003c\/li\u003e\n\u003cli\u003ePower supply: 1x Filtered IEC, 100 to 240V AC, 47 to 63Hz\u003c\/li\u003e\n\u003cli\u003e1RU rack mountable\u003c\/li\u003e\n\u003cli\u003eAll aluminium construction, anodised and laser etched\u003c\/li\u003e\n\u003cli\u003eDimensions (HxWxD): 44x445x123mm (no rack ears)\u003c\/li\u003e\n\u003cli\u003eWeight: 1.11kg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cbr\u003e\u003cdiv align=\"center\" class=\"datagrid\"\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cspan\u003eSpecifications\u003c\/span\u003e\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eProduct Range\u003c\/td\u003e\n\u003ctd\u003eGLENSOUND Silence Detectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003ePlug Type\u003c\/td\u003e\n\u003ctd\u003eUK\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"alt\"\u003e\n\u003ctd class=\"rowheading\"\u003eProduct Contents:\u003c\/td\u003e\n\u003ctd\u003eSD1, 1U rack ears and screws, IEC mains cable 2m, handbook\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd class=\"rowheading\"\u003eCountry of Origin:\u003c\/td\u003e\n\u003ctd\u003eGreat Britain\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cbr\u003e","brand":"Rapidwarehouse","offers":[{"title":"Default Title","offer_id":48101384618249,"sku":"GGBOB375078-RWWS-","price":552.89,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0740\/1747\/2777\/files\/GGBOB375078-1.jpg?v=1720093172","url":"https:\/\/www.rapidwarehouse.com\/products\/4x2-audio-silence-detector-amp-switch-sd1","provider":"Rapidwarehouse","version":"1.0","type":"link"}
