The perfect affordable desktop recording solution. With two channels of recording piped into your computer over convenient USB, the USB Dual Pre might just be one of the most cost-effective ways to strecording on your computer. A pair of XLR-1-4" combo inputs let you use the USB Dual Pre to plug in a variety of sound sources, and you even get a pair of balanced 1-4" outputs to feed a PA or other audio devices. Portability is no problem, as the USB Dual Pre can be powered by USB bus power, its own internal battery, or by an external 12-volt power supply (sold separately). Getting started recording needn't cost a fortune, as evidenced by the USB Dual Pre from ART.
