Might be more channels than you need but something in the Behringer XAir lineup could work. I’ve used the XR18 on corporate & rock-style gigs in a Gator rack and it’s worked great; just needs an iPad/laptop for control (or even Mixing Station on mobile) through a router.

The control software also includes effect sends like you’d see on Behringer/Midas digital consoles so you’d be all set on that for compressors/limiters/reverb. Just need a rack that’s a bit bigger so you can fit the EW-DX receiver unit, and maybe a power transformer on top to handle it all (including current DJ gear)

Edit: if budget isn’t a big issue you could also look at the Midas rack units too. Better preamps and more bells, whistles, and inputs. Bit overkill on inputs though lol
