- Hi guys and girls,
In this video we take a close look at the High Pass Filter. What is it? According to Ken "Pooch" Van Druten, it's the third most important step (after correct mic placement and gain structure). And he's right. I mean, of course he is. He's mixing Iron Maiden!!!
How to set it up? Examples and cool tricks!
Hope you like and enjoy it.
Cheers André

Thanks! Just came across your great channel! I am going to buy an Allen & Heath SQ 5 in a few weeks, when I sold some older stuff!
It’s time for a studio centerpiece without endless cables, moving from gear to gear…just a great sounding centerpiece! Grüße von einem ehemaligen Hessen, jetzt Kalifornien, 😉 Thorsten
Brilliant!
Oh, yea HPF, must be on every channel. I use hpf on bass guitar at 44Hz, because that is lowest note on 4 string bass. Another great video Andre 👏👏👏👍👍👍
About cutting low end, it always depends on the specific track. If your acoustic guitar is your only low end then cutting too much might make your song sound flat and thin. Sometimes I almost cut nothing of the low end in such a scenario. The best EQ IMO is the positioning of the mics during recording. It might be then, that there is only little or almost nothing to cut in general. Otherwise there can be situations where you have to cut a lot, but that really depends on the recording and the music style.
Hi Thorsten,
you are absolutely right with your remarks.
My point of view is mostly that of a livesound engineer. In that field, the HPF is not only a soundtool, but also a kind of damage control device. Since P.A. systems mostly have more than enough power in the lowmid and low end, the HPF can (often) be set higher, than in studio applications. And to your point: If I´d mix Ed Sheerans guitar, I´d leave much more lows in the mix, than if it is an acoustic guitar in a full rock/popband scenario.
Cheers
@@AndreSchaier 👍Thanks Andre! Great channel, I will get my SQ5 in a few weeks and will watch a lot of your videos! Thorsten
Hi, very interesting to see this, only I always have my hpf on 100 because otherwise I think that singing the low passages makes the voice so thin, I just use that proximedie effect to sing the low tones more easily, but I don't know if this is the right way but somehow I like this :) in addition I have a sennheiser skm 6000, which itself has an adjustable hpf, I set this to 100, then I have more bass than I set the hpf on the sq5 to 100 I don't know why, but I'm still researching to get the best possible sound
Mic proximity effect is commonly a bell curve, centered about 200Hz, boosted as much as 12dB, with a bandwidth as much as four octaves. This is often best dealt with EQ first, then high pass.
Hi Timmy,
Thanks for your comment!
I think what you said may be not quite correct. The proximity effect leads to increased bass responds below 200Hz and down and is dependent on the distance and the frequency. So there is not a specific center frequency per se.
Why wouldn´t you use a HPF and safe one band of your PEQ for further soundshaping? What is the sonic advantage, when using the PEQ vs HPF?
Cheers,
André
This link to a pic of proximity effect seems to work. mynewmicrophone.com/wp-content/uploads/2019/07/mnm_What_Is_Microphone_Proximity_Effect_And_What_Causes_It_large.jpg
Hi Andre, How do you use LiveProfessor with Waves Soundgird I/O on SQ5?
Can I eliminate breath rumbling in the mic using the high pass filter? Like p and other consonant sounds that are very annoying.
Hi,
yes can to a certian degree. If you can´t get enough of the plosive sound out of the signal, go old school and use a foam pop filter for handheld mics or a attachable pop screen for studio mics.
Hope that helps
