The plug-in includes high and low frequency shelving equalizers (which can be switched to peaking curves via the BELL
button) and two overlapping equalizers with adjustable Q.
• The LF section operates over a frequency range of 40Hz to 600Hz and is capable of up to 16.5dB of cut or boost.
Selecting BELL in this mode switches the equaliser to a peaking curve.
• The LMF section operates over a frequency range of 200Hz to 2 kHz and is capable of ±20dB of gain with a continuously
variable Q from 0.5 to 2.5.
• The HMF section operates over a frequency range of 600Hz to 7kHz and is capable of ±20dB of gain with a continuously
variable Q from 0.5 to 2.5.
• The HF section operates over a frequency range of 1.5kHz to 22kHz and is capable of up to 20dB of cut or boost.
Selecting BELL in this mode switches the equaliser to a peaking curve.
As default, the Duende PCIe EQ is set to the G Series EQ curve. The G Series shelving curves have a degree of
overshoot/undershoot (depending on whether you are boosting or cutting) below the selected HF frequency or above the
selected LF frequency. At any Q setting, the bandwidth of the HMF and LMF sections varies with gain, whereby an increase
in boost or cut increases the selectivity of the EQ. This type of EQ can sound effective when used at moderate settings; the
gentle Q curve lends itself to the application of overall EQ on combined sources and subtle corrective adjustments to instruments
and vocals.
