• Band enable/disable. Enables/disables the Low , Low-Mid , Mid-High and High
bands. Enabling a band allows it to be processed with equalization.
• Frequency. Sets the center frequency for the selected band (Low, Low-Mid, Mid-High and
High). The valid frequency range for each band is as follows:
• Q. Sets the width of the selected band (Low, Low-Mid, Mid-High and High), which determines
the amount of surrounding frequencies that will be affected when adjusting the band. A low Q
value gives a high bandwidth for the filter band, resulting in a smooth shaping of the sound and
little audible 'coloration'. Filtering will however be less accurate, since a wide frequency range
around the center frequency will be affected. A high Q value reduces the bandwidth, improving
filter accuracy but also creating sharp dips or peaks in the frequency spectrum. The width of the Q
is expressed in terms of octaves. The valid range is 0.1 to 16.0 and the default value is 1.3.
• Level. Boosts or attenuates the selected band (Low, Low-Mid, Mid-High and High).The valid
range is -18.0 dB to +18.0 dB and the default value is 0 dB.
• Low band filter type. Toggles the Low band between Bell and Low Shelf mode. In Bell mode,
the Low band boosts or attenuates a range of frequencies around a central point in a bell shape.
In Low Shelf mode, the Low band boosts or attenuates the set frequency and all frequencies
below it.
• High band filter type. Toggles the High band between Bell and High Shelf mode. In Bell mode,
the High band boosts or attenuates a range of frequencies around a central point in a bell shape.
In High Shelf mode, the High band boosts or attenuates the set frequency and all frequencies
above it.
• Low Pass filter enable/disable . Enables the Low Pass filter, which attenuates high
frequencies above the Low Pass frequency while allowing other frequencies to pass unfiltered.
• Slope (Low Pass). Specifies the ratio of how the Low Pass filter attenuates frequencies above
the Low Pass frequency. Slop is expressed in decibels per octave. The range is from 6 dB to 48
dB in 6 dB increments.
• LP. Specifies the cut-off frequency for the Low Pass filter.
• High Pass filter enable/disable . Enables the High Pass filter, which attenuates low
frequencies below the High Pass frequency while allowing other frequencies to pass unfiltered.
