The input graphic equalizer has 15 bands, allowing a variation of ± 12 dB per band, with a pitch of 0.1 dB, with frequencies equally spaced
in 2/3 octave, in the range of 25 to 16 kHz in accordance with ISO requirements . The graphic equalizer acts on the two inputs simultaneously.
The DSP 2.8X comes with 12 graphic equalizer presets: FLAT, LOUDNESS, BASS BOOST, MID BASS, TREBLE BOOST, POWERFUL, ELECTRONIC,
ROCK, HIP HOP, VOCAL, POP, and PANCADAO (heavy beat). These can be found under the “Graph EQ Presets” menu on the main screen.

The parametric equalizer allows you to choose a gain / attenuation at a specific frequency, as well as the bandwidth of that equalizer by means
of the Q factor, the smaller the Q the greater the width of that equalization band, affecting to a greater extent the neighboring frequencies .
The DSP 2.8X has 9 parametric equalizers distributed as follows, 1 for the inputs and 8 for the outputs (1 for output).
