Did you read Fons response? "That's just a shelf filter and some gain".</pre>

Yes... it's a possible way of implementing a tilt... and?<br>

One shelving filter does it all. In addition you anyway need to adjust
the loudness impression. One knob can't do it.</pre>

I don't care about loudness (at the moment).<br>

Please explain it.
You have to equal shelving filters, IOW based on the same frequency and
the same quality, bandwidth.
What is the difference between increasing one filter 1dB (aka +1dB) and
decreasing the other one 1dB (aka -1dB) or just using one filter
increasing or decreasing 2dB and adjusting the overall volume?</pre>

Undoubtedly true, but what's the point?<br>
You have to give -1 dB before using the +2 dB shelving (again, two
knobs).<br>
I know the math... I was just asking if there exist a tilt eq! If
not, no problem :) I go with shelving.<br>
The only difference using a cascade of 2 shelving in place of a gain
stage + 1 shelving is in the phase response of the system. So in the
90% of the use case there will be no difference between this two
approaches but, again, that's not my original question.<br>

Thank you all for the replies!<br>
