I bought this mixer to replace a small and noisy older mixer for my studio. I needed one with plenty of inputs, since I don't want to reroute cables unnecessarily.
I find it very quiet and the microphone inputs are very nice and clean for vocals. The compressors, phantom power, and equalization works super well for my application.
I like the visual overview of all the input cables coming in, which makes it easy to check and verify the routing of all cables.
My only regret is that I still wish the input faders would be full length, even though that would make the whole unit even deeper.
The effects section might not be that useful in a studio situation, maybe more suited for live use, but I've used the built-in reverb on an old synth module with good results and might find more use for it.
If you really don't need a digital mixer, I think this is a great choice, with or without the effects section.
It's a real work horse in my opinion.
