{"product_id":"cad-usb-control-ground-noise-control-device","title":"CAD - USB Control – Ground Noise Control Device","description":"\u003cp\u003eThe smallest member of the CAD (Computer Audio Design) noise-control family is also one of the easiest wins. The USB Control is a thumb-sized passive device that plugs into any spare USB A socket in your system and quietly reduces high frequency noise.\u003c\/p\u003e\n\u003cp\u003ePlenty of audio components have unused USB sockets. Music servers, upsamplers, clocks, routers, network switches and digital interfaces can all benefit, and USB A sockets now turn up on many amplifiers and integrated music players too. Those ports carry +5V power that often feeds sensitive audio circuitry, and they are an entry point for noise. The USB Control reduces noise on both signal ground and the +5V line, from the kHz range up into the GHz range. CAD designed it to improve rhythm, timing and soundstage without \"slowing down\" the music.\u003c\/p\u003e\n\u003cp\u003eIt fits any available USB A socket, whether or not that socket is in the signal path. CAD likes it in firmware or service sockets and in sockets for connecting hard drives. There's no need to power anything down to fit or remove it, and you can use one on several components. \u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cp\u003e• Passive: plugs into any unused USB A socket, in the signal path or not\u003c\/p\u003e\n\u003cp\u003e• Reduces noise on signal ground and +5Vdc\u003c\/p\u003e\n\u003cp\u003e• Effective from kHz into the GHz range\u003c\/p\u003e\n\u003cp\u003e• No setup, no power required\u003c\/p\u003e\n\u003cp\u003e• Suits music servers, upsamplers, clocks, routers, network switches, digital interfaces, amplifiers and integrated music players\u003c\/p\u003e\n\u003cp\u003e• Fit or remove without powering down\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cp\u003e• Type: passive\u003c\/p\u003e\n\u003cp\u003e• Connector: USB A (plugs into spare USB A sockets)\u003c\/p\u003e\n\u003cp\u003e• Noise reduction: signal ground and +5Vdc line, kHz to GHz\u003c\/p\u003e\n\u003cp\u003e• Size: thumb-sized\u003c\/p\u003e\n\u003cp\u003e• Installation: no need to power down \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"CAD","offers":[{"title":"Default Title","offer_id":68343158997215,"sku":null,"price":895.0,"currency_code":"NZD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0056\/4078\/1914\/files\/cad-usb-control-front-web.jpg?v=1793331463","url":"https:\/\/www.hifi.co.nz\/products\/cad-usb-control-ground-noise-control-device","provider":"The Real Music Company","version":"1.0","type":"link"}
