why mad?
TT bays are very convenient (space) and last forever.
TRS bays are handy if you have synths TRS-TS inserts and unbalanced fx.
XLR bays are handy if you have mics. (just plug the mic or the xlr loom from the booth into the front)
there's two TRS bays here one soldered one jack-jack
three XLR (for mic and line amps and tie to other)
5 TT bays, soldered
I have to go through all of these again. LOL
