Introduction to the Peace APO Tutorial
Here are the actual values to input into Peace APO, no graphs, just numbers to input yourself to make your Sennheiser HD8XX headphones sound close to the HD800s. I’ve also zipped up some presets for you to drop in the Equalizer directory for an even easier time.
Let’s turn those HD8XX’s into HD800s, let’s get you the easy way to do it first, but, before that let me link you to my other article that teaches you how to install Peace & Equalizer APO. Click ME to visit the article.
Here is a zip file with 5 Peace APO presets that include the official Oratory preset, and 4 more presets made by me, to listen to, Dance, Rap, Rock, and one just for Michael Jackson’s Thriller.

Now that, that’s out of the way, let’s get down to business.
#1. Open Peace APO and you get the following screen.

Do you see at the bottom the words, Gain Values, Quality (Q), and Filter? Those are the values we will be changing to EQ our HD8XX’s, NOTE* This will work for any headphone not just HD8XX. Before we get started we have to change the settings to make sure we can put in .1 values, if we don’t do this then they will snap to .5s and we don’t want that.
#2. Click on the ‘Settings’ button near the far bottom right.
#3. Click on the ‘Sizes and Amounts Settings’ tab up top (as shown in picture)

#4. I highlighted the Snap to dB gain area, changed this to 0.1, and clicked the ‘Save’ button at the bottom left to bring you back into the main Peace APO interface screen.
Settings for the first Preset (Oratory)
Now I’m going to walk you through inputting the official ‘Oratory Preset’ setting. After that you will know how to input values and I’ll just give you numbers to input my personal presets for those who didn’t want to download the zip files from the beginning of this post.
#5. Below is a picture of the exact ‘Oratory Settings’ well… settings you need to input to make them sound close to the HD800s. You can go ahead and match it exactly but I’m going to go ahead and walk you through it anyways. Below are the settings on how they present it to you. Maybe it’s self-explanatory, but I’ll teach you how I like to be taught myself, we will be inputting all of this, in an easy-to-input way.

Below, I went ahead and drew squares around the main settings you will be changing, and put numbers to try and explain them in detail. #1 is the Pre Amp you will need to change, #2 is the red minus sign, #3 is the Gain and Quality (Q) values, and #4 (in red) are the filters. Let’s reset that tutorial step counter and get down to business!

#1. Set the Pre Amplifying (top left, pic #1) to # to -7.4 , actually put the minus sign in there too, it’s required. Get in the habit of hitting ‘Enter’ after each input to make sure it sets.
#2. Click the ‘Red Minus Button’ (see pic #2) until you have 10 frequency bands
#3. Start from left to right, with band #1 being the first frequency, see the picture it’s at 105.
#4. I work from a top-to-bottom workflow, for example, in frequency band #1, I start at the top by inputting the number 105, then I look at the bottom and input to the right of ‘Gain Values’ 5.5, Then I take it a step-down and input 0.71 near the Quality (Q) section.
Now see ‘Filter’? See the red line doing a ramp? Maybe you don’t, but there’s certainly a picture there, click it, then look near the bottom and select ‘Low Shelf Filter Q as slope Control’ and you do that for every frequency band and you are all set, but if you’re not, let me tutorialize that and reset that tutorial #, because here we go!
#1. Up top near Pre Amplifyng type the actual negative/minus sign on your keyboard and the numbers 7.4. Like this: -7.4
#2. Look to the bottom near Gain Values, Type: 5.5
#3. Near Quality (Q) Type: 0.71
#4. Click on the small box picture of a wave graph and change it to ‘Low Shelf Filter Q as slope Control’ it should be a red line/ramp.

That’s it! Now I’ll simplify it just a little more and have you on your way to inputting these numbers in no time.

- Picture to = ‘Low Shelf’

- Quality (Q) = 0.3
- Picture to = ‘Peakfilter’ (first choice)
- Frequency Band #3 = 850
- Gain Values = -1.6
- Quality (Q) = 1.1
- Picture to = ‘Peakfilter’ (first choice)
- Frequency Band #4 = 1400
- Gain Values = 2.5
- Quality (Q) = 2.5
- Picture to = ‘Peakfilter’ (first choice)
- Frequency Band #5 = 2000

How to control Bass, Mids, Warmth, ETC.
Phew, that was intense! Now I’m just going to go over real quick what certain sliders do if you want to start making your own presets. Here is an image provided by the Oratory guys.

There it is! So, Frequency is band 1, and so on. So…
- Frequency 1 controls BASS
- Frequency 2 controls WARMTH
- Frequency 5 controls MIDRANGE ACCURACY / SHOUTINESS
- Frequency 6 controls GLARE
- Frequency 10 controls AIRINESS
That completes my tutorial that took me like 2 hours to make! If you use any of it please link to my site, http://moco.net , I hope this was useful to someone as when I came to use the program, I was completely lost.
