That is almost certainly a homebrew modulation monitor.

would the cryptic inscription on the front offer any clues?

But that could just be a clever attempt to mask the real insidious use for a box with a knob, switch and a couple of meters.

You know... like a clandestine loudness control for which only the PD has the combination. Who is to say that the center zero meter isn't a listener monitor to tell the PD if more or less people approve of his loudness control knob adjustments?

Labels are just a convenient way to containerize things we can't control. :mrgreen:

I've seen similar things which were merely remote meters, but this one seems to be more 3D than those.

Sure, it goes up when he increases the loudness. Don't encourage him. :lol:

Incidentally years ago I had a FCC inspector give me the side-eye for having a big VU meter in the studio rack, fed by rectified off-air audio because it was labeled "modulation". He wanted to see the calibration..... Or I could take the label off.
