From here, rotate the knob again to tweak the selected parameter’s value to your liking. Once a desired setting has been
reached, push the knob in again to confirm.
Frequency
– This parameter’s value determines the frequency of the selected effect, ranging from 400 Hz to 16.0 kHz.
Width [aka “Q”]
– The Q control adjusts the bandwidth of a filter. However, the Q value itself is dimensionless; it has no unit
of measurement. Some equalizers use the fractional bandwidth of the filter, measured in octaves, to express this parameter.
The two parameters are inversely related; a high Q value corresponds to a small fractional bandwidth. The following table
lists some equivalent Q and fractional bandwidth values. It ranges from 0.5 to 3.
Gain
– This parameter’s value determines the amount of gain applied to the selected effect. It ranges from –8 dB to +8 dB.
LPF
– Low-pass filters are utilized to cut out high frequencies. It ranges from 6.0 kHz to 18.0 kHz.
HPF
– High-pass filters are utilized to cut out low frequencies. It ranges from 80 Hz to 600 Hz.
Before moving on to ‘Presets’ and ‘Reset’, let's take a quick peek at the parameters of delay, echo and slapback,
as well as their EQ settings.
