About Equalization

If you are using your E62i / E31i / E30i to equalize a complex mono or stereo signal (for example, the master mix output of a mixing console), a more natural sound can be obtained by setting up gentle “smile” curves than by simply cutting or boosting individual frequency areas. For example, if you decide that you want to boost one particular frequency area by 6 dB, try boosting the adjacent areas (the frequency directly above and below the target frequency) by 3 dB each.

If you are using your E62i / E31i / E30i to equalize signal from individual instruments, here are a few general suggestions: Boosting the low frequency areas of instruments such as bass drums or bass guitar will add warmth and make the sound “fatter”; conversely, you may want to attenuate the low frequency components of instruments such as cymbals, high-hats, and shakers so as to “thin” them out. Attenuating mid-range frequencies

(the 1 kHz - 5 kHz area) can give a vocal performance more of an “FM-radio” feel, while boosting those frequencies can help a vocal cut through dense instrumentation. Be careful not to boost high frequencies too much or you risk adding hiss to the signal, though just a touch can help add “shimmer” to an acoustic guitar, ride cymbal, or high-hat. You can also use the highest or lowest equalizer sliders to reduce hiss (by attenuating high frequencies) or rumble (by attenuating low frequencies). Rumble can also be attenuated by engaging the front panel HPF switch(es), which insert a High Pass Filter centered at 80 Hz.

If you are using an E62i or E31i to equalize the signal of an overall mix in a live performance or recording environment, check out the sections in this manual entitled “Using the E62i / E31i With an RTA” and “Using the E62i / E31i to Ring Out A Monitor System” (on pages 24 and 25).
