it's hard to believe no one ever noticed that boosting 10k resulted in boost at 5k. it's either some kind of error on your part, or all this talk about golden ears is bullshit (or maybe no one ever buys this EQ...).

I ask every one of you to test it for yourself.

And you could test the Maag eq...

i may be able to test this once i get home (if i don't forget and if i'll feel sufficiently bothered to). just to be sure it's not VST Plugin Analyzer's fault, can you also run pink noise through it and look at the spectrum analyzer?

Yes, I double checked it in my DAW, using white noise and SPAN.

It models SPL RackPack Eqs. Here's the quote from SOS review of hardware:
Sound On Sound wrote:The Full Ranger has frequency centres of 40Hz, 90Hz, 150Hz, 500Hz, 1.8kHz, 4.7kHz, 10kHz and 16kHz, and the cut and boost is controlled by a set of miniature sliders. Unlike a traditional graphic equaliser, where the filters are set one octave apart with identical response curves, this SPL design tailors the response of each filter band based on musical principles (rather than mathematical ones). Essentially, the filter curves get wider (lower Q-settings) the further you go up the audio spectrum.
Basically, the idea is that SPL Free Ranger behaves as original hardware, not as a digital EQ.
I can't believe that the original hardware is that wrong, manipulating mostly 900Hz when moving a 1K8 slider....
And if the algos are wrong, it's strange that not all frequencies are wrong in the same way.
Anyway the answer of the vendor is crap ("it's not a bug, it's a feature...")

The response changes the more you boost. For 1k8 band It starts somewhere around 1800 Hz and then changes the more you boost. Being graphical equalizer, I assume that the response of original hardware was tuned by ear for the best musical response. Nobody promised precise digital EQ.

yep, the 10K band has a 5k center frequency. @graphic EQ, i understand the need to tune by ear etc., but being off the mark by 5k isn't "tuned by ear" in my book, it's just stupid.

funny thing is, *cutting* at 10k results at ~7k cut.

Maybe because it's a passive equalizer?

Does the peak/null frequency move with the gain?

Sorry, I won't waste any more time with it, but you're free to try it yourself with Christian's analyzer.
