Jack, In my experience balanced inputs are more important than balanced outputs in a control room context. If you want to keep things simple, forget the inserts. I wired mine out actually, so the signal never leaves the module at that point. If I need outboard I go from multitrack to outboard to line in. The line inputs on a series one should be balanced - is there an integrated patchbay on yours? The tricky thing I've seen regarding this is that the "line in" signal hits the module first (balanced line receiver) then goes to the integrated patch bay as an unbalanced signal (but it's called multitrack or tape out) which normals to the "line in" which IS unbalanced. I bypassed all of this as well so the signal doesn't leave the module. It's a shorter path at least, and with a 30 year old board it's that many fewer contacts to pass signal through.
The echo returns are balanced input, they shouldn't give you any trouble. Your patchbays are unbalanced - are you sure? Perhaps they're just wired that way? Please double check the 1/4" input jacks on the back for line in, are you sure they're not TRS? You sometimes can get away with lifting the cold side of the balanced signal or taking it to ground, but it really depends on what piece of gear is on the other end. I tried to get away with it, but with a patchbay and a variety of outboard there will be problems. Sorry if this is convoluted, it's a complex topic when you're getting a control room together. I hope it helps - hollar back!
