If it's not 600 ohms, the 0.77blah blah blah number changes. The new number
is left as an excercise for the reader.

Well, +13 is lower than +22 :) Mixers have either an input pad trimmer or a
knob to adjust
this. So, shouldn't be an issue coming to going.

That's because the .7746 is *RMS*. When you plug '10' into the equation,
that
means 10Vrms or 28V pk-pk. That is where the +22 comes from.

Again, just buy a mixer that has attenuators on the insert bus.
