of Equalizers |
Three main types of EQ are:
Shelving, Graphic, and Parametric
- SHELVING
- Found in most mixers
(including Ramsa and Mackie)
- "Bass" (LF) and
"Treble" (HF) controls boost or cut
begining at a certain point ("knee")
- Sometimes midrange (MF) is
included, and sometimes with adjustable midpoint
frequency
- GRAPHIC
- Octave, 1/2 Octave and 1/3
octave varitites
- Separate boost/cut adjustment
(usually a slide pot) for each band
- Display of slide pots in a row
shows a "graphic" picture of EQ
- PARAMETRIC
- Separate adjustment of
Boost/Cut, Center Frequency, and Q (sharpness of
peak/dip)
