Roland’s Rubix series is a versatile line of USB audio interfaces that let you record clean and clear audio, even in less-than-ideal environments. That’s because Roland built them to be as mobile as possible. A sturdy metal housing lets you toss your Rubix in your bag and go, and since it communicates via class-compliant USB, you can leave your laptop at home and track right on your iPad. Microphone preamps offer the kind of clarity you don’t normally find on such an affordable interface, and bonus features such as a ground lift and onboard dynamics processing (on the 24 and 44 only) make it easy to capture high-quality audio wherever you go.
