So you want to record your 2box but you're broke and can't afford an RME Babyface audio interface? Don't worry, you can get this cable for 15 bucks and plug the right and left to your 1-2 outs and the usb to your computer, install free asio drivers and the free software audacity, hit record and there you go, you'd found the cheapest way to record your playing without spending more than you have already (providing you have a computer already)
