Voice Fullness at 120Hz; Boominess at 200 to 240Hz; Presence at 5KHz;

Sibilance at 7.5KHz; Air at 12 to 15KHz

Harmonica Fat at 240Hz, bite at 3-5kHz

Conga Resonant ring at 200 to 240Hz; Presence and slap at 5KHz

Whether used to alter the timbre of an instrument, control

feedback, or improve speech intelligibility, it's important to know

what effect each portion of the frequency spectrum has on the

sound.

In summary, the frequency spectrum can be divided up into six

important sections.

AUDIO OCTAVE RANGES

FREQUENCY RANGE WHEN USED PRODUCES WHEN USED TOO MUCH

THIS EFFECT PRODUCES THIS EFFECT

16Hz to 60Hz sense of power, makes music muddy

felt more than heard

60Hz to 250Hz Fundamentals of rhythm makes music boomy

section, EQing can change

musical balance making it

fat or thin

250Hz to 2000Hz Low order harmonics of telephone quality to music

most musical instruments 500 to 1KHz horn-like,

1K to 2KHz tinny,

listening fatigue

2KHz to 4KHz Speech Recognition 3KHz listening fatigue,

lisping quality, "m", "v",

"b" indistiguishable

4KHz to 6KHz Clarity and definition of sibilance on vocals

voices and instruments,

makes music seem closer to

listener, adding 6dB at 5KHz

makes entire mix seem 3dB

louder

6KHz to 16KHz Brilliance and clarity of sounds sibilance, harshness on vocals

As with any signal processor, the

M-EQ 230

should be used with

discretion since too much of a good thing can make the sound

worse instead of better. Although it is a wonderful device and will

help your sound a lot, remember that a little goes a long way.

If you're using the

M-EQ 230

for tonal contour of an instrument or

voice, Figure 5 will help you zero in on the key frequencies of

some popular instruments.

Remember: The chart serves only as a starting point. Ultimately,

you must use your ears as a guide.
