4800/4820 User Manual

®

The 4800 and 4820 units offer 6-Band Notch Filter that can be inserted in the Input section. The Notch
filter is designed to provide a significant amount of cut in very narrow frequency bandwidths to remove
room resonances and other unwanted artifacts.

Notch On/Off switch

This turns the Notch filter on and off.

Flat/Restore switch

These buttons either flatten all bands (Flat) or restore (Restore) all bands to their previous settings.

Filter Select switch

This selects the Parametric EQ filter to be adjusted.

Filter On/Off switch

This turns the Selected (1-9) parametric EQ on and off.

Frequency (Fc) fader

This sets the frequency of the selected Notch Filter, and is adjustable between 20Hz to 20kHz.

Gain fader

This sets the amount of boost or cut of the selected Notch Filter, and is adjustable b6 and -36 dB.

Q fader

This sets the Q (or bandwidth) of the selected Notch Filter and is adjustable between 16 to 128.
