Equalizers are segmented into sliders corresponding to different frequency bands.
Equalizers take many different forms, but in general they are segmented into at least three bands that each represent specific frequency ranges within the audio spectrum, which runs from about 20Hz to 20kHz. The user adjusts the relative volume of each band by raising or lowering the corresponding slider. Many stereo systems and digital music devices have built-in equalizers, usually segmented into at least eight bands. The lowest, or "bass," frequencies are found on the left. The high, or "treble," frequencies are found on the right.
Instructions
1. Lower the slider that is furthest to the left if the bass is overwhelming, or "muddying," the overall mix without necessarily being too loud. The furthest-left slider corresponds to the lowest frequency the equalizer can adjust, usually in the 30-40Hz range. Lower the slider to a few decibels (dB) below zero to start with and then adjust downward in small increments until the muddiness subsides.
2. Lower the second slider from the left if the bass is over-dominating the mix. On equalizers with eight or more bands, this slider will correspond to the 50-60Hz range. Lower this slider to a few dB below zero and then downward in increments until satisfied with the bass level.
3. Lower the three or four left-most sliders to reduce the overall bass volume without fine adjustment. On equalizers with eight or more bands, these sliders will correspond to roughly the 20-125Hz range, which encompasses the entire bass portion of the audio spectrum.
