Big Knob Studio : 99% satisfied!

I use it to control my active monitors in the studio. I have connected the main monitors to output A and subwoofers to output B. It's great because I can fine tune the amount of bass without having to reach for the subwoofer.

All the inputs and audio interface work like a charm, I use it as a mixer between 3 sources (DJ mixer and two iMacs), I sometimes connect my laptop or iPhone to the front 3/4 stereo in and everything works exactly as it should. Headphones monitoring also work great.

My only complaints are that it heats up a little too much for my comfort even when inactive (but no issues whatsoever) and when powering off in the back, the subwoofer makes a boom sound (even if the output for it is switched off).

I'm VERY happy to have this, it solved sooo many problems in just one device.
