12:2 EQ and filtering
EQ
BFD2’s EQ is based on a well-known classic console design. It offers 4 bands of EQ, includ-
ing two parametric mid bands.
Low and High bands
The Low and High bands are switchable between a bell (with a fixed Q of 2.5 octave) and a
shelving response (with a fixed rolloff of 12 dB per octave).
• Low band frequency range:
40 to 600hz
• Low band gain range:
+/- 16.5 dB
• High band frequency range:
600 to 14khz
• High band gain range:
+/- 20 dB
Parametric Mid bands
The Mid bands feature bell curves with adjustable Q.
• Low Mid Band frequency range:
200hz to 2Khz
• High Mid band frequency range:
800hz to 7khz
• Q range:
0.5 octave to 2.5 octave
• High band gain range:
+/- 20 dB
Band power
Each band has its own Power button allowing you to save CPU by only using the bands you need.
SC
Enabling the EQ’s SC button allows you to EQ the channel’s sidechain input. This can be very useful to EQ a sidechain input
before it enters a compressor, for example. For this function to work, the EQ must be placed before the sidechain processor in the
channel’s effect slots.
Frequency Display control
You can change EQ curves by clicking and dragging the graphical display in the EQ effect interface.
To edit a band in this way, move the mouse cursor over the display. The display is divided into 4 zones for each band, each high-
lighted in a different colour, corresponding to the colour of each band’s standard controls on the interface.
With a band highlighted, click and drag up/down to adjust the band’s gain, and left/right to adjust its frequency. For the two Mid
bands, clicking and dragging up/down while holding down the ALT key allows you to adjust the band’s Q.
Filter
The Filter effect provides non-resonant high-pass and low-pass filters for broad tonal shap-
ing of signals.
It can be used to roll off the low end in Overhead and Room buses, or to remove ultra-low
frequencies from kick drums, espcially when low-shelving EQ is applied.
HP Freq
The high-pass filter removes frequencies below the specified frequency which can be set
within a range between 20hz and 500hz.
LP Freq
The low-pass filter removes frequencies above the specified frequency, which can be set
within a range of 35 Hz to 3 kHz.
Power buttons
Each filter features a power button – when it is turned on, the filter is enabled, and when it is turned off the filter is bypassed.
