De-Esser Page
Each channel has an integrated de-esser. This is a dynamically controlled
filter, normally used to reduce the ‘s’ components of a microphone signal.
The filter range is placed over the signal’s ‘s’ frequency components; if an
‘s’ component is detected in the audio signal, the level within the filter range
is dynamically reduced.
Graph
The lower green graph represents the current, static filter curve of the de-
esser. The horizontal axis represents the log. frequency, while the vertical
axis represents the de-esser’s attenuation.
Please note that this is a static
indication only, intended to give you an idea of the current filter settings
. The
actual attenuation in the selected range depends on the current signal level,
combined with the
Threshold
and
Ratio
settings.
The upper green graph indicates the current
Threshold
setting.
ON
Button to enable/disable the de-esser section of this channel; highlighted if
on.
Auto Thr
Automatic threshold setting depending on the current signal content. If
Auto
Thr
is ON, the button is highlighted and the threshold graph as well as value
turn gray. If
Auto Thr
is set to OFF, the Attenuation setting changes to
‘Ratio’, and threshold is not grayed out anymore.
Attenuation
If
Auto Thr
is set to ON, the de-esser’s Attenuation can be adjusted here in
a range of 0 to –50 dB (Max).
Frequency
Center frequency of the de-esser’s filter band. It is indicated in Hz and can
be set with the rotary encoder below the field in a 4...10 kHz range.
Q
Q factor (bandwidth) of the filter. It is indicated as a plain number and can
be set with the rotary encoder below the field in a range of Q = 0.27 (wide)
to 8.7 (narrow).
Threshold
The threshold is the audio signal level above which the de-esser starts to act
within the adjusted filter band. It is displayed in dB and can be set with the
rotary encoder below the field in a 96 dB range.
Ratio
Level reduction ratio within the filter range, if an ‘s’ component is detected
in the audio signal. This can be set with the rotary encoder below the field in
a range of 1:1 (no effect) through 20:1 (heavy de-essing).
