What specifically are you want to know about it? I had one for about 1 1/2 years so I have a lot of experience with one. Awesome cleans, low gain, mid gain but the high gain lacks. Has a IIC+, Dual Rect, and SLO and that's it. There's one digi high gain model but those are normally not the best. Very little support from avid since it's been out, 3 firmware updates (fixing bugs only) and 1 expansion in 3 years. It's a great little unit but where it lacks it lacks very badly. Ask me a few questions, I could write a whole report on it so give me something specific to work off of.
