Every Equalizer Setting Explained

Equalizers are the most commonly used and misunderstood tool in an engineer’s toolkit. 

The ability to bend, shape and carve frequencies at-will is an audio superpower not to be taken lightly. It’s important that sound engineers understand what is going on behind the knobs and fully understand the impact of what every EQ parameter can have on a sound.

In this tutorial, Grammy winner Fab Dupont explains everything you need to know about:

  • Fully Parametric and Semi-Parametric EQ
  • High and Low Shelves
  • Bell curves and Q settings
  • High Pass and Low Pass filters (aka Low Cut and High Cut filters)
  • Frequency graphs
  • Analog vs Digital EQs
  • Personal tastes (sonically) and how to find the right tools to match
  • The subtle differences between the hundred of different EQs available

Learn the theory and concepts you need to know about EQ controls and parameters so no matter what EQ is put in front of you, you’ll be able to mold the sound to your liking with no second guessing.

So easy to follow for a beginner. I'm surprised at how few questions I'm left with. Excellent.

Super... super... merci pour la clarté du cours et merci aussi d'avoir un prof aussi cool et passionnant qui va finir par me faire résilier mon abonnement Netflix tellement la série Puremix est addictive...

Juste génial, mais j’ai une question : est-ce qu’on peut catégoriser les EQ selon l’utilisation qu’on en fait ? Par utilisation, je veux dire si on enregistre, mixe ou masterise. En tout cas, merci pour ces brillantes explications.

perfect. Been using EQs for 10 years and was not bored till the end. Learned stuff and revised other. Thanks

Wonderful Fab! Thanks for remind us that the power of an EQ shouldn't be subestimated.

Loved this so much Fab. Would really enjoy your thoughts on other types of dynamic processing to :) I could not really hear the difference between phase aligned and not on avantone pro mp1 mixphones, but maybe i should have used speakers with good low end? That reminds me, could you do a vid on phase?:p

Great tutorial, thanks! Just like to have seen dynamic EQ covered as well. Or is this more a compression related topic? Thanks, PM tutorials are of great quality and fun to watch. L.

Just when you thought you knew what an EQ can do...Fab brings you back to sweep your rudimentary concepts that you "thought" you mastered. Would have liked a more expanded explanation of linear phase EQ and its consequences where and when they occur. Otherwise well-presented and most comforting to know that we can "go back" for a targeted review when and where we "hit that brick wall" while mixing ;)

Please in português or Spanish! =)

Excellent. I would have liked mention of the disadvantages of linear phase eq. (I.e., why not use them always?)
2016 Oct 17
Thanks Fab! :)

Fantastic tutorial. Has to be one of your best. Everyone needs to see this. I'm guilty of having to many EQs, mostly too that having only the knobs, by using your ears. But the visual EQ to me is the best way to mix. Very interesting, thanks.
2016 Oct 13
Great video Fab! I like the approach you took and I learned some very useful information.
2016 Oct 12
Nice video Fab. I like how you emphasized when a linear phase eq can be very helpful with the kick drum example and mentioning if you have a problem with the bottom of your mix, you might have a phase issue.

thanks Fab! I was surprised the Surfer EQ, thanks for your tutorials!!!!
2016 Oct 12
Thanks Fab!

Really useful video. I find that I actually eq like Fab said "going down a rabbit hole". In my mind I am making things clearer but in fact I am making things less real and harder to emote feelings from. Wonderful lesson!!
2016 Oct 11
Renault?? Are you serious my capitain?! Useful video nevertheless! Thanks!
2016 Oct 11
This is a serious and essential lecture. It's a great video! Thanks!

This is such an important video to anyone wanting to know more about EQ. It's impossible to fit everything into a mix without carving your EQ points in so that everything can work together in a symbiotic way. I'll watch this video again and again for new ideas and inspiration on EQ. We love you Fab:)

Another outstanding lesson from Fab. Just happens to be exactly what I've been trying to learn and get better at. And always with the bonus nuggets of info, tips, tricks, ways of looking at things, what to listen for etc... Even if you think that you already know about a topic, watch Fab's lesson on it anyway, you'll be glad you did.
