I'm using this to create my own keyboard mix, sending the mains to the sound guy and the monitor out (through a Y adapter from the headphone out) to my own powered stage monitors. This way, I have complete control over my own stage sound without interfering with the sound guy's signal. And I can up the gain on a few boards that tend to have a low signal on their own. I was looking at a few cheaper options, but I'm so glad I got this. The sound is absolutely clear - no coloration, no deadening, no distortion. What you put in, you get out. There's PLENTY of headroom and a VERY LOW noise floor. For my uses, this thing is perfect!
