Equalizer

The Equalizer module is a high-quality 4-band parametric stereo equalizer with 4 fully parametric mid-range bands. The low band can act as either shelving filter, as peak filter (band-pass), or as cut filter (low-pass, band 1 only).

Band Settings

On/Off

Activates/Deactivates the corresponding section.

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.

Equalizer Section

Type

You can choose between the EQ types Low Shelf, Peak, High Shelf, and Notch. For band 1, 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 the set frequency. You can choose between different slopes: 12 dB, 24 dB, or 48 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.
