Q-DI 4-Channel DI Box and Line Mixer

I am a drummer and play with backing tracks and a click. The mixer is independent of the DI, so if you turn the volume up or down for the headphone mix, it does not effect the DI send. I have one channel for backing tracks, one for the click and one for a monitor mix. I DI the backing track to the soundman. If I am playing a song with a click, I have the click up and the monitor mix down, so I can lock in on the click. If I am playing a song without a click, I turn the monitor mix back up. This works great!
