The AR16 arrived today.....bad photo attached. LOL! Still waiting for some other things to be delivered. Hopefully everything is here by Friday so I can start putting it all together this weekend. Going with a 10 mic setup. Keeping channels 1 & 2 open for guitars as both have a high-impedance setting to accept a guitar or bass directly. So all 12 XLR's will be used in one way or another.
Overall, for the price, this hybrid mixer-interface has a ton of features as I've read just about everything in the manual. Plus the build quality is very good. Not all plastic, only the side panels are. Feels very sturdy in your hands as well.
If I had to nitpick....the finger rests on the faders do have some horizontal wobble although nothing that's going to make a difference when using it. The vertical movement of the faders is smooth and solid.
I also prefer the design of, and the taller, tapered and thinner knobs on my Mackie to the short, thicker knobs on the AR16. And although the mixer has the ability to record to the built-in stereo SD card recorder, they don't include even low capacity SD card for those without one to allow testing right out of the box. Well, I guess you can't have everything at $599. SD cards are cheap.
I've read elsewhere of users complaining about the knobs wobbling but have not experienced this when turning them on the unit I received. You'd have to really push side-to-side firmly to get any sense of wobble.
Once I get everything setup and comfortable with it, will post an overall full review. I have a feeling it's going to be good.
