Connect an y-cable to the booth output. One end goes directly into your recording device, the other is connected via nano patch to your monitors. Then you turn the booth output to full gain (or what ever your recording device needs) and then you use only(!) the nano patch to control your monitor volume. Master volume is unaffected, of course.
Will work, I did so very often. E.g. when I need to insert an isolator in a club with a mixer without insert loop connectors. Can do the same thing with balanced master output. What ever you want. The nano patch can handle balanced and unbalanced signals.
