Equalization for music

The Graphic Equalizer is designed not only for use in preventing feedback and equalizing uneven room frequency response to be flat, but also for equalizing frequency response to your tastes and producing favorable sound for you. Fig.1 shows each frequency band and its corresponding auditory feeling. Fig.2 and Table 1 show the relation between each musical instrument and its frequency band. They can be of great help in the equalizer operation. (They are referenced from a book entitled "Practical Guide for concert")

	INSTRUMENT EQUALIZATION CHART							Table 1

Acoustic guitar

Bass strings resonate between 70 to 120Hz, body around 300Hz.

Avoid boosting these to stop feedback. 3kHz and 5kHz gives

great "clarity".

Electric guitar

Resonances differ-depending on type. Good full sounds around

300 to 500Hz. Clarity at 3kHz.

Bass guitar

Extreme lows are at 60 to 90Hz. "Pick" or "pluck" sounds are

around 800 to 1200Hz. Upper harmonics clarified about 3kHz.

Human voice

Good fullness at 150Hz. Watch for "boominess" around 250Hz. Mid-range 10kHz.

Piano (Acoustic)

Bass strings responate around 100Hz. Watch for subharmonics at

30 to 50Hz.

Piano (Electric)

Good mid-clarity at 3kHz to 5kHz thins out rapidly in high end. Be careful around 1.5kHz to 2.5kHz to avoid the "bar room sound".

Organ

Usually dies under 200Hz. Has great mid-sounds around 1200 to

2000Hz. Top end cuts off at 6kHz.

Violin

Richfullness at 400Hz. Natural mids around 1500 to 2500Hz. Avoid "scratch" sounds at 8kHz.

Brass instruments

Watch for "hot" mids around 2kHz. Low end boost around 400Hz. Top end clarity at 6kHz.

Bass drum

Great low "kick" at 40Hz. The mids at 2kHz gives the familiar

"punch".

Snare drum

Good fullness at 100Hz. The "crack" is boosted at 2kHz. Real easy. The snares extend to above 4kHz.

Tom Tom

The main fullness is around 200Hz. The mid punch extends to

4kHz.

Floor Tom

Same as tom, but extends down to 80Hz.

Hi Hat

Watch for the "gong" sound around 300Hz. Good "shimmer" sounds are around 8kHz to 10kHz.

Cymbal overhead

About the same as hi-hat only has more low end around 150Hz.

Talk Box

Depending on the guitar sound driving it and the resonance of each player's mouth, should have great "bite" around 1200Hz and dies above 6kHz.
