LMF
The center frequency of the half-parametric low/mid frequency
filter is set with the LMF control (low/mid frequencies). The
adjustable frequency range is between 30 Hz and 700 Hz so
that this filter covers a range of about 4.5 octaves, allowing it
to be used from the deepest bass to the lower mid range. This
together with the MHF filter ensures that the entire frequency
spectrum is covered.
The LMF filter operates to the proportional-Q-principle, in other words the bandwidth is
dependent on the selected boost or cut.
The -/+ control (right to the LMF control) determines the boost
or cut of the LMF filter.
The maximum values are at +/- 12 dB.
MHF
The center frequency of the semi-parametric mid/high
frequency filter is set with the MHF control. (MHF: mid/high
frequencies). The frequency range can be set between
680 Hz and 15 kHz so that this filter covers a range of
4.5 octaves and can be equally be used in the lower
mid as well as the high frequency.
The MHF filter operates to the proportional-Q-principle, in other words the bandwidth is
dependent on the selected boost or cut.
The -/+ control (right to the LMF control) determines the cut of
the MHF filter.
The maximum values are at +/- 12 dB.
AIR
The high frequency filter in the equalizer module is described
as AIR. A coil-capacitor filter with so called bell characteristics
and a center frequency of 19 kHz comes into operation here. At
this frequency the maximum possible accentuation is +10 dB,
the maximum possible damping is -10 dB.
