Nope. It's an iRig DJ mixer. Handy as hell - 2 stereo channels with EQ, and an independent HP out.

I plug an iPad into channel 2, and that allows me to mix the backing tracks, or break music back INTO the kb speakers with instant volume and EQ, and right at my fingertips. The PA900, itself is plugged into channel 1, but the main slider is OFF. I use the HP out to feed the house mix, or my system, depending on the venue. (Gain, and EQ are still active)
This allows me to have a 2 zone mixer within reach of my left hand. You might notice, I tweak it a lot. I'm kind of "conducting" the backing arrangement.

*** IMPORTANT - if you try this, be sure you have your MAIN VOLUME off in the KB channel, otherwise it'll get fed back into the internal sound system, and cause a never ending paradox-like feedback loop.
