Equalization & Tuning Chart

The following charts can be used as guidelines for tuning / setting an equalizer. This is a skill that takes hours and hours of practice, so don't be frustrated if you find it is taking time to get right.

Frequency Range	Effected Area	Results Of Excessive Boost
16hz - 60hz	Sense of power, music is felt more than heard	Makes music sound muddy
60hz - 250hz	Fundamentals of the rhythm section. Equalizing can change the musical balance making it fat or thin	Makes music sound Boomy
250hz - 2000hz	Low order harmonics of most musical instruments horn-like. Listening fatigue may result.	Telephone-like quality to music.,br> 500 to 1kHz will be horn-like 1kHz - 2kHz will sound tinny
2kHz - 4kHz	Speech recognition	3kHz - Listening fatigue Will add a lisping quality to voices M", "V", & "B" will become vague
4kHz - 6kHz	Effects clarity and definition of voices and instruments. The music will seem closer to the listener	Sibilance on vocals (harshness) Addong boost at 5kHz will make the music seem louder.
6kHz - 16kHz	Brilliance and clarity of sounds.	Sibilance and/or harshness on voices.

Key Frequencies:

Voices Fullness at 120Hz; Boominess at 200 - 240Hz; Presence at 5kHz; Sibilance at 7.5kHz; Air at 12 - 15kHz.

Harmonica Sounds "Fat" at 240Hz; will add "Bite" at 3 - 5kHz.

Conga Resonant ring at 200 - 240kHz; Presence and "Slap" at 5kHz.

Bass Guitar Attack or pluck is increased at 700 or 1kHz; Bottom will be added at 60 or 80Hz. String noise at 2.5kHz.

Bass Drum "Slap" at 2.5kHz; Bottom at 60 or 80Hz.

Snare Drum Fatness at 240Hz; Crispness at 1 - 2.5kHz; Bottom at 60 - 80Hz.

Hi-Hat and Cymbals "Shimmer" at 7.5 - 10kHz; "Klang" or Gong sound at approx. 200Hz.

Toms Attack at 5kHz; Fullness at 240Hz.

Floor Toms Attack at 5kHz; Fullness at 80 or 120Hz.

Electric Guitar Body at 240Hz; Clarity at 2.5kHz.

Acoustic Guitar Body at 240Hz; Clarity at 2.5kHz; Bottom at 80 or 120Hz.

Piano Body at 80 - 120Hz; Presence at 2.5 - 5kHz; Crispness at 10kHz; Honky-Tonk sound at 2.5kHz as bandwidth is narrowed. Resonance at 40 - 60Hz.

Horns Fullness at 120 - 240Hz; Shrill at 7.5 or 5kHz.
