I've seen unbalanced inserts all the way up to API. Having balanced line inputs in the DAW age puts you ahead of the curve, seriously! Just forget about those inserts, you don't need them. There's isn't even a switch to put them in circuit or not for comparisons. The unbalanced outputs are fine, really. The only problem they'll cause is if you have a pin 2 / pin 3 hot conflict headed into an unbalanced input, you may end up driving ground and thus get no signal. Also maybe some hum if you drive a long line into another room where another unbalanced/quasi balanced device receives the signal. My aux sends have plenty of drive into said other room where amps with decent balanced inputs drive headphones.
You will need to do some trial and error - I had to do not much - and I get by with my series 1e in a room full of various outboard and my own balanced patchbay that I put together myself, avoiding the inserts but using everything else, AS IS. It's a good thing that the bay is balanced. I'd recommend getting everything on the same type of bay though, for a reduction in headache symptoms. use the force....
