The equalizer is definitely the most important piece of equipment in your audio rack! Most transceivers do an excellent
job of passing all the midrange frequencies between 300Hz ~ usually with an added dominance between 500Hz ~ 800Hz. Unfortunately, most
stock transmitters roll-off the bass frequencies below about 150Hz and down, as well as the high frequencies above about and up. So, we
need to do basically three things:
* Reduce the Midrange
* Increase the Bass
* Increase the Treble
Taking a look once again at GRAPH 1 and GRAPH 2 above, you can see what an EQ can accomplish when set up. Below is a graphical representation of what EQing I had to implement in order to get some flatness out of my Kenwood TS-850S/DSP-100 after passing through its . and DSP filtering.
