To ensure highquality audio, this device requires proper, sufficient USB-C power. A good reference for the specs, is the \u003ca href=\"http:\/\/https:\/\/www.raspberrypi.com\/products\/type-c-power-supply\/\"\u003eRaspberry PI USB-C power supply\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003eQ: I'm getting static noise when connecting the device to my line-in.\u003cbr\u003eA: Your setup is experiencing ground loop interference. When both devices are connected to the same USB-C hub (or powered via the same source), they share a common electrical ground. If there’s a slight voltage difference between the grounds of the devices, it can cause a ground loop, which introduces static, hum, or buzzing noises in the audio signal. Power the devices separately, or use a ground loop isolator, or use the line-in of an audio interface\/mixer with builtin-ground isolation.\u003cbr\u003e\u003cbr\u003eQ: I've connected my midi-keyboard to the device, but hear the same sound on each midi-channel\u003cbr\u003eA: This device is a multitimbral midi device, therefore the instrument on each midi-channel can be configured by sending so-called 'program change' messages.\u003cbr\u003e ","brand":"Serdaco BVBA","offers":[{"title":"32gb high quality class 10 micro sd card ( € 15 € 18.15 )","offer_id":57773543358848,"sku":"SF2","price":119.79,"currency_code":"EUR","in_stock":true},{"title":"16gb high quality class 10 micro sd card ( € 12 € 14.52 )","offer_id":57773543457152,"sku":"SF2","price":116.16,"currency_code":"EUR","in_stock":true},{"title":"No Card","offer_id":57773543555456,"sku":"SF2","price":101.64,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0980\/2622\/6048\/files\/2335998380.jpg?v=1771751200","url":"https:\/\/new.serdashop.com\/products\/sf2","provider":"Serdashop","version":"1.0","type":"link"}
