When this unit is in normal mode, a single parametric equalizer
function is available in addition to the 13-band graphic
equalizer, so that points that cannot be adjusted using the
graphic equalizer can be corrected using the single-band
parametric equalizer.
In addition, in pro mode, the parametric equalizer can be used
to adjust five bands in the treble to medium range, and five
bands in the medium to bass range.
