Broughton RFE VS. Broughton HPF/LPF

[Zbysek]

Then the mid knobs just work like a regular parametric eq? Does anyone know the Q of the mids?

Yes

The Q is 0.9

Yes, yes, and I don't know the Q but you may be able to estimate it from these measurements of the Mid control sweep:

Are the other two peaks the HPF and LPF? They’re 12db/8ve right? Thanks for this!

The other two peaks seem like Mid EQ control in two different positions (all the way CW and all the way CCW)...

Zbysek is correct, the previous graph shows the Mid control at min / 50% / max frequency, and min / max gain

High Pass looks like this:
(purple = max resonance, green = 50% resonance, yellow = min resonance)

And Low Pass:

Thank you for posting these graphs.

What I take from them is that I will generally boost the resonance only when the HPF is set higher (let's say 60Hz and higher) and when the LPF is set lower (let's 5kHz and lower).
