inuke can't set filters below 20hz, but that is no problem. we just start with one at 20, then add a little shelf to push it down to 16.

here is exactly what to put into the inuke dsp.

step 1: on the filter tab, 2nd order highpass filter at 20hz (butterworth, 12db / octave)



step 2: on the parametric eq tab, filter 1, gain -4db, frequency 20hz, type: HS12



then use filters 2, 3, 4, etc. for any other EQ that you wish to add.

additional step.


this additional step is only necessary in some instances depending on how much drive voltage the avr/pre-amp produces.


since the high pass with negative gain lowered the overall level by 4db in this case, that can be raised back up by adding the same amount of gain on the filter/crossover tab. so go back to that tab and increase the gain as shown with the red arrow.



If I wanted to tune it to 17 hz I would make the parametric eq -3, and then add the +3 on the filter/crossover tab right?

yeah...that is roughly the way it works. 2nd order high pass is 12db per octave and going from 20hz to 10hz is one octave, so it just happens to work out that for this region it is roughly 1hz per db of negative low shelf 'gain' and then as you point out an equal amount of overall gain just to bring the level back up.

Listen. It's All Good.

For a martycube, what would be a good highpass setup with the inuke?

So, no need for any wizard tricks in the DSP. I can just set the 20hz highpass and use the BUT12 setting?


Is the limiter setting that has been suggested, based on the real world performance of the inuke? If I'm running a single SI18 D2 bridged, the recommendation is to set the limiter to 93.8vp for ~1100 watts. But to me, that is 1100 sales hype inflated watts. Has anyone tested the limiters accuracy?

No tricks. Start with but 12, try but 6 as well and see which one is better. Limiter setting is accurate .
