Superb monitoring controller. The sound is very transparent, lots of outputs for different setups. It just lacks a mic input for talkback, but the box's mic is good and you can adjust its gain. There is a click (in the headphone outputs and the MIX and CUE outputs) that is noticeable and unpleasant when pressing the TB buttons. I have a huge crackling problem at the SPDIF input when I am only at 96kHz and turn on an SSL control surface; the problem might come from the power supplies, yet I am on a Furman circuit. Oh yes, also no On/Off button, no settings or LCD and LED savers when not in use. And nowadays I think manufacturers need to make an effort in this area. Maybe a firmware version will come with these problems fixed. Otherwise, apart from that, it's a superb machine; once you own it, you can't part with it.
