Rockbox, Clip+, and Klipsch Reference S4 decent SQ

(1/1)

MacDonals:
I have been searching for some tips on how to properly equalize my Klipsch Reference S4 inner earbuds.  I had my Rockbox EQ tweaked for my Ultimate Ears, but since those broke I really needed to get my EQ settings for the S4s.

This was complicated by the fact that I really didn't know much about a parametric equalizer, so the Rockbox Clip+ implementation is not terribly meaningful to a noob.  So I came up with a method that allowed me to configure the EQ on my desktop and translate that to my Rockboxed Clip+.  I know it's not exactly precise, but my method provided a "good enough" analogue so that I only needed to tweak the settings once I got the EQ onto the device.

Setup:

* WinAmp 2.95 (still available here)
* Electric-Q VST Plugin.  Posihfopit editions
BE SURE TO DISABLE ALL SOUND CARD ENHANCEMENTS AND OTHER (WINAMP) EQUALIZERS


I loaded up my typical sample file, indicative of the music I listen to (heavy guitars, vocals and lots of loud / quiet variation), "Quake" by Balance & Composure.  I configured a 10 band EQ in Winamp / Electri-Q.  I took the settings and translated them into Rockbox.  Here are the settings for anyone interested.

I've done a lot of searching and reading about equalizers, I hope this helps at least one other noob.

I really wouldn't recommend using all ten bands, that's going to eat battery. Are you sure you need that many? It's a parametric EQ after all

GREAT point and again, something I'm still learning about.  I will try to make a 5-band eq.  I was using 10, because I (naively) thought I needed to use them all :-/  I was confused because there's no way to turn the other bands "off".

Also, any tips on how to get a similar curve using 5 bands instead of 10?

Sure there is.

If a band has 0 gain, it is "off". Though I admit this may be non-obvious to some.
