If you buy a 19" case you prob get a blank front panel with it.
You could use that for a try out before you order your design from the panel manufacturer.
Its so easy to miss something out.

Is it correct that the onboard variable hpf is going from 75 to 200 hz?
what would be the easiest way to lower the values when using a potentiometer?

Hello.

The schematic i have on my computer states clearly 15hz-400hz.

The filter is made up of two sets of RC (12db/oct). R varys when you turn the dual pot.

If you want higher min/max freq, lower the capacitors.
For lower min/max, increase the caps.
