On-screen graphic, 011 Stereo Parametric 4EQ
This is a stereo 4-band parametric equalizer. Bands 1 and 4
can be set to either peaking or shelving modes, and you can
modulate the gain of Band 2 in real-time.
PARAMETRIC EQ
Trim [0…100]
Sets the input level.
Band1 Type [Peaking, Shelving-Low]
Peaking creates a bell shape around a center frequency.
Shelving creates a slope up to a “shelf,” which then extends
all the way to the bottom or top of the frequency range.
Band4 Type [Peaking, Shelving-High]
Selects the EQ type for Band 4. See “Band1 Type,” above.
Band1 Fc [Hz] [20…1.00k]
Sets the center frequency of Band 1.
Q [0.5…10.0]
Sets the bandwidth of Band 1. The higher the value, the
narrower the band becomes.
Gain [dB] [–18.0…+18.0]
Sets the gain of Band 1.
Band2 Fc [Hz] [50…10.00k]
Sets the center frequency of Band 2.
Q [0.5…10.0]
Sets the bandwidth of Band 2.
Gain [dB] [–18.0…+18.0]
Sets the gain of Band 2.
Band3 Fc [Hz] [300…10.00k]
Sets the center frequency of Band 3.
Q [0.5…10.0]
Sets the bandwidth of Band 3.
Gain [dB] [–18.0…+18.0]
Sets the gain of Band 3.
Band4 Fc [Hz] [500…20.00k]
Sets the center frequency of Band 4.
Q [0.5…10.0]
Sets the bandwidth of Band 4.
Gain [dB] [–18.0…+18.0]
Sets the gain of Band 4.
Red lines show the frequencies of bands 1, 2, 3, and 4.
