Analog Elemental Series
Dual-Band De-Esser | Control Elements
Low S-Reduction
Use the LOW S-REDUCTION control to adjust the intensity of the sibilance reduction in
the lower frequency range. The center frequency for sibilance recognition is set at 7.6 kHz
in FEMALE mode and 6.4 kHz in MALE mode. For more information, please refer to section
“MALE/FEMALE“ below. The bandwidth of the low-band de-esser is 1.44 kHz.
Scale values for the filter are displayed in dB. The actual reduction values, i.e. after phase
cancellation, are displayed in the lower SR LEDs. Thus, when the control is set to 3 dB, actual
reduction might only be of around 1 dB.
The SR LEDs display sibilance reduction between -1 dB and -14 dB, first in 1 dB increments and
from 6 dB on in 2 dB increments.
In practice, for most applications, the best results are usually achieved when LOW
S-REDUCTION is set between 3 and 7.
High S-Reduction
Use the HIGH S-REDUCTION control to adjust the intensity of the sibilance reduction in the
upper frequency range.
The center frequency for sibilance recognition is set at 11.2 kHz with a 3 kHz bandwidth.
Scale values for the filter are displayed in dB. The actual reduction values, i.e. after phase
cancellation, are displayed in the upper SR LEDs. Thus, when the control is set to 3 dB, actual
reduction might only be of around 1 dB.
The SR LEDs display sibilance reduction between -1 dB and -14 dB, first in 1 dB increments and
from 6 dB on in 2 dB increments.
Please note that the MALE/FEMALE button has no effect on the high-band de-esser.
In practice, for most applications, the best results are usually achieved when HIGH
S-REDUCTION is set between 3 and 7.
Male/Female
The MALE/FEMALE button allows you to adjust the low-band de-esser to the type of voice
being processed. When engaged, the mode selected for the low-band de-esser is FEMALE,
otherwise the de-esser works in MALE mode. The mode selected affects the center frequency
for sibilance recognition: in FEMALE mode it is set at 7.6 kHz, while in MALE mode it is set at
6.4 kHz.
These values have been determined by practical experience, so that the processor adapts
better to gender. Nevertheless, you cannot take for granted that these settings will suit every
single male and female voice. Consider the MALE/FEMALE function as an additional tool to
help you set the low-band de-esser more precisely according to your needs. Always trust your
ears to find the best settings.
Signal-LED (SIG.)
The SIG. LED indicates that an audio signal reaches the input with a level above -20 dB. This
LED helps the operator especially in complex setups to determine immediately whether the
Dual-Band De-Esser actually receives any signal.
