When used in intercom or talkback applications, the ST-VOX1 may be triggered directly from an unbalanced microphone. In many such installations the microphone or other audio source must be preamplified, making the ST-VOX1 an ideal mate to work with the STM-1 preamp. The unbalanced output from the STM-1 can be used to trigger the ST-VOX1, while the STM-1 balanced output is used for the audio feed.\u003c\/p\u003e\u003cul\u003e\n\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003cli\u003eSwitching Controlled by Voice Signal\u003c\/li\u003e\n\u003cli\u003eSwitching from Mic or Line Level Signals\u003c\/li\u003e\n\u003cli\u003ePrecise Threshold Adjustment\u003c\/li\u003e\n\u003cli\u003eDPDT Switching Contacts\u003c\/li\u003e\n\u003cli\u003eOpen-Collector SLAVE Output\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RDL","offers":[{"title":"Default Title","offer_id":49568911060,"sku":"20529","price":591.06,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2241\/9163\/products\/a55f173147183d385f9a91287d6122cd.jpg?v=1504266256","url":"https:\/\/collection-import-export.myshopify.com\/products\/rdl-st-vox1-installation-voice-operated-relay","provider":"collection-import-export","version":"1.0","type":"link"}
