One of the most versatile and comprehensive equalization plugins created. With an almost overwhelming selection of modeled curves, characteristics and features it truly would be the 'desert island' EQ plugin if not for one thing; it's a bit buggy. Preset handling is TERRIBLE, at least on a PC. Using the plugin's own preset management is hinky (saved presets not being found even though they appear in the browser), using the host's preset management is a show stopper (in Pro Tools, preset management crashes the app). There are also some GUI issues that aren't show stoppers but they make me think twice before instantiating this on an insert. If not for these issues, it would be my go-to, user default. It already is in all practicality but sometimes I feel bad for my control surface when it has to put up with the verbal abuse Kirchhoff can trigger when it goes sideways. That being said, sonically, Kirchhoff is STELLAR. It a tone color box, it's a surgical tool, it's vintage, it's modern, it's whatever you want it to be baby. I don't know if there's a limit on the number of bands one can enable but the flexibility is fantastic if you want to audition different curve models using the same settings. The dynamic EQ section is unbelievably comprehensive. I mean, c'mon, who else makes a trigger sidechain with it's OWN SIDECHAIN!?! The precision one can exercise when de-essing/de-booming/de-harshing; fixing tonal problems, is unprecedented. The interface can be a bit daunting sometimes. There's a LOT of info in the GUI to digest but it's welcome in comparison to a minimalist approach found in some boutique plugins; none of that one-size-fits-all-non-editable-macro knob nonsense. This is an engineer's EQ. Once you find your way around the interface, you know where you need to go in order to achieve the results you want. If you can get past the shortcomings this is the most useful eq you'll ever use.
Kirchoff filter
★★★★★

I have all these types of filters in the world. Kirchoff is undoubtedly the best filter that exists so far in the vast constellation of all filters. What can I say, it is friendly, fast at work, clear, unambiguous and has excellent algorithms.
LOVE THIS!!

I have been with Plugin-Alliance for almost two years now and I couldn't be happier! These plugins are amazing AND are always added to my bundle when they are released. Thank you Brainworx! I love this EQ because it's so wonderfully precise for when you really need to find that exact frequency that needs cutting BUT ALSO allows amazing control over the Q and slope of the cuts. Best EQ I have seen for this purpose. Kick ass!
This is the engineer's best friend!

While Kirchhoff-EQ seems to "mimic" many aspects of Fabfilter's Pro-Q product line, the GUI is the least of my concerns regarding my switch from the Pro-Q 3 to Kirchhoff-EQ. Both seems to be close to equal, but Kirchhoff-EQ swiftly became my daily go-to toolset not only for the usual musical and surgical needs, but also the astoundingly featured dynamic EQ section! This is an absolute killer EQ!
Best EQ on the market

I love this EQ. Adding compression and expansion to each band is super helpful and easy. Great that the UI is sizeable. One of the best plugins I purchased in a while!
Spectacularly good!

I didn't think there was a EQ that could trade blows with E******rium and ***-Q . I was wrong! This thing has a very swift and pleasant workflow, it's very easy to make fine tuning, and make the changes that you desire and need.
Amazing EQ

This EQ is simply amazing the more I have been messing with it in a new mixdown. I loved Fabfilter Pro Q 2 which is a great EQ, but now it is permanently retired. The Kirchhoff EQ allows so much dynamic control to suppress trouble frequencies that I would normally use level automation for each track, but now this EQ will save me so much time. I bought the all bundle but I can say from experience Kirchhoff is worth every single penny of it's price tag. It is a must have for any serious recording artist or producer. I must really say thank you to Plugin Alliance for including such an incredible product in the All Bundle.
Replaced Pro-Q³ for me

but please don't take too much longer to fix the numerical display of the output gain (in v.1.60). This bug is a bit concerning because the knob and the display seem to clash and I'd hate to see older projects not recalling the right setting anymore once the fixed update is out. Bug was not present in v1.51 of ThreeBodyTech's original.
Kirchhoff-EQ
★★★★★

As a client of your mix and master subscription, I have been extreemly satisfied with the different options of EQ processors implemented in the plan. The Tomo and others are great sounding tools that I have used for both mixing and mastering. In comparison, I have also used the Pro-Q for many a mix. Every plugin PA gives you for an EQ offers a different objective with different results. However, the Kirchhoff sounds incredible! It's functions and options exceed the Pro-Q ( they are laid out in a very similar manner ) and in my opinion, this is the best software EQ I have ever used. From using it on individual tracks, to the mix buss and mastering; the Kirchhoff offers possibly everything you would need to create professional sounding results. Highly recommended....
