GHG high pass filter

I've noticed that there are two dials below the handwheel on the GHG compensator.

What was their use? Could the high pass filter be adjusted with them?

As far as I understand the higher the frequency, the better the accuracy, but also range gets worse. I believe that such adjustments had to be possible as with fixed filter one wouldn't hear the higher frequencies without a proper amplification.

My leading theory is that one of these knobs adjusts the cutout frequency, while the second one adjusts the volume gain, but I haven't found any sources that would confirm that.

Any help in figuring this out will be greatly appreciated!
