When you pick the Ultralite-mk3 Hybrid, you won't have to be worried about limiting yourself to just one connection type. This audio interface is the first ever to feature two types of connectors: USB 2.0 and FireWire. These two connection types are available on nearly every new Mac or PC laptop or desktop computer, so you'll be set wherever you decide to record! When you use FireWire, your Ultralite-mk3 Hybrid will get all the power it needs right from your computer - including the phantom power needed for your condenser microphones. When connected via USB, you can use the included power adapter to get full functionality.
