Curve EQ module

The Curve EQ module allows you to fine tune the frequency spectrum of your tracks.

To adjust bands with finer resolution, hold down the SHIFT key while adjusting a band.

The Curve EQ module contains the following controls:

Clipping LED. Shows if the input signal to the Curve EQ module is clipping. If there is any distortion in the MixStrip signal chain, the clipping LEDs let you identify where the clipping occurs.

Curve EQ enable/disable . Enables/disables the Curve EQ module.

Graph. Shows the equalization curve. Each band is identified by a unique color, and the sum of all bands is displayed as a white line. The EQ plot resolution is 12dB. Adjust the equalizer by manipulating the graph. For details, see To interact with the Curve EQ graph.

To adjust a band’s gain, drag up/down. The valid range is -18.0 dB to +18.0 dB and the default value is 0 dB.

To adjust a band’s frequency, drag left/right. The valid frequency range for each band is as follows:

Table 144. Default center frequency for each band  

Band	Type	Frequency range	Default center frequency	Default Q factor
Low	Shelf	20.0 - 20000.0 Hz	79.6 Hz	1.0
Low-Mid	Bell	20.0 - 20000.0 Hz	317 Hz	1.3
Mid-High	Bell	20.0 - 20000.0 Hz	1261.9 Hz	1.3
High	Shelf	20.0 - 20000.0 Hz	5023.8 Hz	1.0

To adjust a band’s Q, hold down the ALT key and drag up/down. 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 Q response is constant at all gain settings. The valid range is 0.1 to 16.0.

To adjust parameters with finer precision, hold down the SHIFT key while dragging.

Band enable/disable. Enables/disables the Low , Low-Mid , Mid-High and High bands. Enabling a band allows it to be processed with equalization. The knobs and graph curves are color-coded per band:

Low = Red

Low-Mid = Yellow

Mid-High = Green

High = Blue

To interact with the Curve EQ graph

The Curve EQ graph is divided into four sections, which correspond to the Low, Low-Mid, Mid-High and High bands.

To adjust a band’s gain, drag up/down.

To adjust a band’s frequency, drag left/right.

To adjust a band’s Q, hold down the ALT key and drag up/down.

To adjust parameters with finer precision, hold down the SHIFT key while dragging.
