How to equalise using ElectriQ parametric equaliser

 

A quick guide for people wanting to equalise their headphones properly, there is already a guide which shows you how to equalise using pink noise, Sinegen etc. so I will not cover that. I found it quite difficult to use a parametric EQ at first. After spending some time learning it I thought it would be helpful to share this as I have had some PM's asking how to use it and I have not seen a specific guide for this on Head-fi.

 

More information on how to equalise here:

1) Use Sinegen to find any peaks in your headphones frequency response, I found it was helpful to save around 3-5 points for each peak + the loudness using the DB selector. You can see in the picture here all the frequencies and the levels and click between them to check the loudness is the same.

 

 

 

 


2) Open electriQ and plot these onto the graph by adding points, double click to select the menu and place the point on the frequency and gain that you recorded in Sinegen. It is a lot easier and more accurate to type the numbers into the boxes instead of trying to drag the points around with the mouse.


3) Once you have plotted all the points on the graph you can draw a box around all of them (by dragging a box on the graph) and select "bypass" for all of them. This means they are not active and you can now use them as a guide. You can see in the picture the points I plotted using the numbers I got from Sinegen.

 

 


4) When placing the actual points for the EQ curve I found it was best to place as few points as possible, mainly in the center of the peaks that were plotted in the previous step. If the curve has a different shape you can place 2 points near each other and use the frequency / gain / bandwidth to get it correct, also you can place points to the left and right if you need to trim or raise the frequencies around that area. Less points means smoother curve and easier to adjust later.


5) Once you have done this you can adjust the bandwidth of each to follow the points you plotted. The best way I found to get the correct shape is using the bandwidth, frequency and gain controls in the control box, dragging with the mouse does not work well and you will not get very accurate results. Here is an example of a curve following the guide.

 

 


6) You can place additional points where needed and use the same technique to get the correct shape, if you want to increase the bass then use the "low shelf" and for the peak I used "peak orfandis". There are other filters you can select as well which are detailed in the manual.


7) When you have the correct shape that follows the points that you plotted you can then delete all the bypassed  guide points because these cause issues with saving properly. Here is a picture of a finished EQ.

 

 

 


8) Once you have the basic shape created you can save this as a default EQ and then you can make any changes from there to get the sound you want. You also will need to create a point and set it to "gain only" to ensure that everything is below 0db. Also keep the default EQ and do not save over it so you can use it again if necessary. Save using the Menu > presets > Export Presets because this is the only way that works properly. You can then use this basic shape to customise the frequency response however sounds best to you using a combination of music and test tones. I found the best for this is a frequency sweep from 20-20khz to get an idea of the loudness of different frequencies.

 

I strongly recommend doing this if you are not 100% happy with your headphones as they are, the results are much better than using a graphic equaliser.

Thanks for taking the time to do this, nicholars. I've bookmarked it for future reference.
