Equalizer (EQ)
Usually an equalizer is used to correct the sound output from
amps or speakers to match the special character of the room,
or to change the tonal character of the sound. The sound is
divided into several frequency bands, and adjustments are
made to the sound by raising or lowering the level of each
band.
By adjusting the sound according to the genre—classical
music being more refined, pop music more crisp, and rock
music more dynamic—you can draw out the special
characteristics of the music and make your performance more
enjoyable.
Three separate EQ sections are available on the instrument:
Element EQ, Part EQ, and Master EQ.
