Default Alephx gain factor

I try to do what GRollins suggest, to take some time, reading to understand how Alephx works.
I stuck in the value of R28, R29, R30 (like R16, R18, R19). How it comes to these values of 100k, 10k and 68.1k? What is the gain factor? Why is there 68.1k, what is the consideration?
I try a simple trace if we use unbalanced input for aleph x. The input is to R18, but the R28 is grounded (so there is R28//R29 to ground). I assume this is how to use alephx for normal input (not balanced input).
I cannot finish the trace, I stuck with the voltages and currents in R18, R19, R16. But it seems that in normal operation input (not balanced) the left side aleph (the inverting output) has less gain than the right side aleph (normal output).
Is it right, that if we use alephx with non-balanced input, the left aleph produce less voltage (or gain) than the right side aleph? (compared to ground)
Or is it alephx is only recomended for balanced input only (so the left and right aleph produce the exact same voltage compared to ground) ?
