I love my ProRack House. I'll keep this short ...
Sounds become easy to realise; transparent.
Fabulous EQ.
Switchable EQ pre/post monitors.
HPF really useful.
Good long faders.
Big red mute buttons.
Really easy to use this desk.
Loads of line-ins.
20 mic channels in a rack desk!!! (12 mono)
Balanced Aux outputs.
Dimmable 'little-light' power.
Truly movable rear connector panel.
Wishes, but I'm being silly really; this desk is great. anyway...
'in-place' soloing, and more output for 400ohm studio cans (classical recording/live use)
Aux master mutes (soundcheck requests, mostly. Can be done if masters kept at 12 for easy re-setting.
In conclusion, this is the nicest desk I've used apart from a Crest a few years back ... and a funky old Chilton desk with switchable mids (300/3k) and transformer mic pres. But that was a very simple 2 aux machine, and large.
