Be able to switch any QU to be an actual Stage Box. No processing no patching having to be done. Put a switch mode and it works like plugging in an AR2412, AR168.
My instance I have an SQ5, a QU24, and a AR2412. QU24 and AR2412 was my initial setup. Upgraded to SQ5 and now my QU sits it out. Setting the QU to be a Stage box now I have plug in play 2x 24 inputs.
Also I can see the QU-SB and SQ-pak being the size they are similar to a stagebox. Just switching them to stagebox mode would work great when upgrading to SQ and not having to buy new stageboxes.
