Why not make an new variant mixer (in series SQ, Qu … whatever) that has no IO ports - just an SNAKE connection / SD card / USB / Headphone port.
The end user would use it with a stage box like DX168.
It would be a gamechanger as most people would prefer the idea of a remote stage box + cat 5 connector compare with old school snakes. A&H could reuse all the tooling / boards from Qu or SQ - just mount them without all the IO. There must be a market for this as it seem pointless to pay OTT for a load of onboard preamps when a stagebox is so much better?
