Thanks for clarifying that, from the only Quantum box I've seen that was the "Quantum" 26x32 interface, it had the all output control. I would gave also assumed they all had that more flexible volume control, that's what I like in the video.

Since the Quantum has "All" mode to control all outputs and your Quantum 2626 does not then why not upgrade/swap your 2626 for a Quantum? Saves less hassle of an external box etc.
