Yes. They weren't kidding when they called it a Mobile I/O. From the ULN2 Juicers Guide:
"One of ULN-2’s many great strengths is the flexibility of its power system. ULN-2 can be powered from any
DC source (including bus power) in the range of 9V to 30V as long as it provides 12 Watts of power. The
DC inputs on ULN-2 are a 2.1mm coaxial power connector, center positive and a 4-pin XLR connector Pin
4 Hot. So if you are powering the unit with a third party power source and it supplies 9V, the power source
will have to provide 1.4 amps of current. If you are powering the unit with 12V, the power source will have
to provide 1 amp of current, and so on."
What I love about the ULN2 is that it's extremely clean, fast, and quiet; has insert points/direct in's for each channel; has separate monitor and headphone outs and level controls; and stores 10 user-definable virtual mixer configurations -- including channel strips -- internally. And while the virtual mixer has to be programed with a Mac, the unit doesn't have to be connected to a Mac to use any of the virtual mixer configurations you've preset. So you can pack it up for a video shoot if you want. There's a real emphasis on squeezing as much versatility out of it as possible. And it works.
