We just put a CQ-20B in our youth/portable system rack. Big improvement over the Qu-SB. I do like the channel pages over the scrolling to the far right on the Qu. That scrolling on the Qu is what probably necessitated the custom layer pages on that unit to begin with. But even with the channel pages on the CQ we are noticing that when we have a small group, say a vocal using a standard XLR jack and a guitar using the multi jack, we have to go back and forth. I can see where a custom page (of 8 inputs) would be a great addition for anyone that is not using more than 8 inputs for a small show.
