Designed for plug-and-play simplicity, only a standard USB Type-B cable (sold separately) is required to connect your laptop and the USB-Pro. It requires no proprietary drivers to operate. Once connected, the USB-Pro will automatically be listed as an available sound card in the audio settings of all popular operating systems, including Windows and Mac, and transport audio via 24bit\/96kHz digital-to-analog converters to ensure signal quality is maintained. A stereo pair of balanced XLR outputs allows you to connect to a microphone preamplifier, PA system, mixing console, or even a powered speaker, with an on-board level control for quick and easy volume adjustments. Should any noise be encountered, ground lift switches are provided, and isolation transformers can be inserted into the signal path to eliminate hum and buzz from ground loops, for a clean connection to the PA.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ctable class=\"table feature-product\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecifications\u003c\/th\u003e\n\u003cth\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAudio circuit type:\u003c\/td\u003e\n\u003ctd\u003eCustom decoder with analog line drive\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency response:\u003c\/td\u003e\n\u003ctd\u003e5Hz ~ 40kHz (30Hz ~ 18kHz with isolation)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDynamic range:\u003c\/td\u003e\n\u003ctd\u003e\u0026gt;90dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGain:\u003c\/td\u003e\n\u003ctd\u003e+8dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTotal harmonic distortion:\u003c\/td\u003e\n\u003ctd\u003e0.01%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Impedance:\u003c\/td\u003e\n\u003ctd\u003e250Ω nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNoise Floor:\u003c\/td\u003e\n\u003ctd\u003e-90dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Output:\u003c\/td\u003e\n\u003ctd\u003e+8dBu\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCombatibility:\u003c\/td\u003e\n\u003ctd\u003eSoftware compatibility: Windows XP\/Vista\/Win7\/Win8\/Win10 and Mac OS, Sound file compatibility: WDM, MME, CoreAudio, DirectSound, WASAPI and .WAV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"2\"\u003eFeatures\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd colspan=\"2\"\u003eMono Sum, Ground lift, Level Control, Headphone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Connectors:\u003c\/td\u003e\n\u003ctd\u003eUSB connector B-type (USB cable not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Connectors:\u003c\/td\u003e\n\u003ctd\u003e2 x XLR-M, 3.5mm headphone output\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExtras:\u003c\/td\u003e\n\u003ctd\u003eUSB 1.1 full speed, Sampling Rate: 44.1kHz \/ 48kHz \/ 96kHz auto sensing, 75dBu stereo separation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr class=\"heading\"\u003e\n\u003ctd colspan=\"3\"\u003eGeneral\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConstruction:\u003c\/td\u003e\n\u003ctd\u003e14-gauge steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSize (L x W x D):\u003c\/td\u003e\n\u003ctd\u003e5.0\" x 3.3\" x 2\" (127 x 84 x 48mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight:\u003c\/td\u003e\n\u003ctd\u003e1.5 lb (0.68kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower:\u003c\/td\u003e\n\u003ctd\u003eUSB bus powered 500mA maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConditions:\u003c\/td\u003e\n\u003ctd\u003eFor use in dry locations only between 5°C and 40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty:\u003c\/td\u003e\n\u003ctd colspan=\"2\"\u003e\u003ca href=\"https:\/\/www.radialeng.com\/product\/usb-pro\/legal.php#Warranty\"\u003eRadial 3-year, transferable\u003c\/a\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/07\/RecordingJUNE-2014-usb-pro.pdf\" target=\"_blank\" title=\"Radial USB-Pro Review By Recording Magazine\" rel=\"noopener\"\u003eRecording Magazine Review\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2018\/04\/Radial-SmartSheetBook-USB-Pro-update-1.pdf\" target=\"_blank\" title=\"Radial USB-Pro Smart Sheet\" rel=\"noopener\"\u003eSmart Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.radialeng.com\/wp-content\/uploads\/2025\/05\/USBpro-UserGuide-WEB-05-2025.pdf\" target=\"_blank\" title=\"Radial USB-Pro User Guide\" rel=\"noopener\"\u003eUser Guide\u003c\/a\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Radial","offers":[{"title":"Default Title","offer_id":47956453228762,"sku":"R800 1050","price":289.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0014\/9585\/9277\/files\/USB-Pro-34-right.jpg?v=1780687053","url":"https:\/\/www.rocketmusicshop.com\/products\/radial-usb-pro-stereo-usb-direct-box","provider":"RocketMusic","version":"1.0","type":"link"}
