6.15-De-EsserInsert

The DriveRack 4800/4820 offers a De-Esser module available on the Input Inserts. This De-Esser effect is ideal for removing unwanted vocal sibilance and is based on the original dbx 902 De-Esser module. A De-Esser works by inserting a high frequency boost EQ filter in the detector path of a Compressor to “bias” the compressor, so it compresses when there is a significant amount of high frequency content in the signal passing through it. This De-Esser offers two modes: Highpass and Bandpass. Highpass mode functions like most other De-Essers with a Highpass or shelving filter in the detector path. Bandpass offers the abil- ity to remove sibilance within a certain band without being affected by other high frequency content. For example, in Bandpass mode the Width can be set so the De-Esser will ignore frequencies above 12 kHz while still removing unwanted sibilance in the neighborhood of 6 kHz.

De-Esser On/Off switch

This turns the De-Esser on and off.

Frequency fader

This fader adjusts the center frequency the De-Esser uses when in Bandpass mode or the corner frequency used when in Highpass mode. The frequency parameter is adjustable between 800 Hz to 8.00 kHz.

Amount fader

This parameter controls the amount of De-Essing. The amount control is a combination of the Threshold and Ratio controls of a Compressor. Increasing the amount lowers the Threshold and increases the ratio ,thereby applying more De-Essing to the signal. The Amount is variable between 0 and 100%.

Type switch

This determines whether the De-Esser is in Highpass or Bandpass mode.

Width fader

The Width parameter sets the Q of the Bandpass Filter, and is adjustable between 16 and .25.
