You get what you pay for, but a little more too
This thing is humungous. Seriously. It cannot be overstated how large this item is and how much space it will take up on your desk. I had only seen pictures and assumed it was similar in size to the Big Knob or Central Station but this thing is wider than a 15" Macbook Pro. That may be a good thing or a bad thing depending on your setup, but I already have too many things competing for desk space.
The main knob is clearly plastic but sufficiently robust-feeling and satisfyingly "clicky" (the volume dial is stepped so you can feel when you move from one position to the next), and the rest of the buttons and knobs feel very solid. Behringer crams a lot of inputs and outputs in this thing *and* an audio interface; haven't tried the interface aspect yet but it seems like this could be an easy way to record on the fly in a pinch. Even though, you know, this thing is huge.
My main gripe is two-fold:
One, this thing is far from transparent. I knew going in that this'd likely be the case considering the active circuitry, but hey this thing was cheap and Mackie's [even cheaper] passive Big Knob won't be out until the summer. This won't affect you hardly at all for your typical band project studio/"I make beats" with Rokit monitors and their like, but if you're rocking $1000+ monitors this probably won't work well for you. Same with the headphone outs.
Two, the "high-pitched whine" that other reviewers have referred to is completely legit. It's real. The ones who can't hear it possibly can't hear that high of a frequency anymore (no joke), but it's there. It's not overly loud, but it's there and annoying. This shouldn't be a deal breaker though, unless you are in a ideally and supremely quiet & treated room, with sufficiently high-end equipment. In which case I'd suggest that you utilize Sweetwater's "3 payments" option and get something worthy of your speakers.
