Equalizer

The Equalizer module is a high-quality 8-band parametric stereo equalizer with 8 fully parametric mid-range bands. The low and high bands can act as either shelving filter, as peak filter (band-pass), or as cut filter (low-pass/high-pass, band 1 and 8 only).

You can add two Equalizer modules to the module chain, Equalizer A and Equalizer B.



Band Settings



On/Off

Activates/Deactivates the corresponding section.

Channel Settings

Allow you to switch between left/right, stereo, and mid/side processing. In Left/Right or Mid/Side processing mode, you can make different settings for the two channels.

Linear Phase

Activates/Deactivates linear phase mode for the corresponding band.

Linear phase mode avoids unwanted frequency dependent phase shifts of the audio signal that might occur with standard minimum phase equalizing.

Note

  • Linear phase mode leads to an increase in latency.

  • In rare cases, for example, when using low cut filtering with a high slope for bass signals, also an unwanted pre-ringing effect may be audible.

Type

You can choose between the EQ types Low Shelf, Peak, High Shelf, and Notch. For band 1 and 8, you can also select the types Cut 12, Cut 24, and Cut 48.

  • Low Shelf boosts or attenuates frequencies below the cutoff frequency by the specified amount.

  • High Shelf boosts or attenuates frequencies above the cutoff frequency by the specified amount.

  • Peak boosts or attenuates frequencies at the set frequency value with a bell shaped filter.

  • Notch boosts or attenuates frequencies at the set frequency value with a very narrow filter.

  • Cut attenuates frequencies below (band 1) or above (band 8) the set frequency. You can choose between different slopes: 6  dB, 12  dB, 24  dB, 48  dB, or 96  dB per octave.

FREQ (20 to 20000 Hz)

Sets the frequency of the corresponding band.

Q

Controls the width of the corresponding band.

Gain (-15 to +15 dB)

Sets the amount of attenuation/boost for the corresponding band.
