you mean ua-25
and I assume you're looking for a multiple channel output for the purpose of headphone cueing? that's the one thing ua-25 lacks at, I've had to learn how to use the visuals on Traktor (waveform on the deck, and level meters on mixer) to compensate for no headphone cueing. As soon as I can afford it I'm upgrading to a FA-101.
if you need headphone cueing one a usb2 interface, I'd recommend the edirol UA-101 which supports multiple audio channel outs.
cheers
