Processing & Parameters
3.10 Noise Gate
The Noise Gate is a process which essentially prohibits signal from passing unless the signal
level is high enough to trigger the set threshold, thereby opening the gate and allowing the
signal to pass.
Noise Gate Parameters
The Noise Gate algorithm contains the following parameters:
• Gate Enable - This parameter turns the noise gate algorithm on or off.
• Gate Release (0 - 99) - Release sets the speed at which the gate ‘closes’ or
attenuates.
• Gate Threshold (-60 dB - +3 dB) - The threshold is the level at which the gate
opens. Anything above the set threshold passes, while signal that is lower than the set
threshold is attenuated.
3.11 Parametric EQ
Parametric EQs allow you to shape the tone of the audio signal. Sometimes these EQs are
needed at various stages of the signal path. The KX100 has Output Parametric EQs (for
equalizing the overall sound system) and Input Parametric EQs (for shaping the tone of the
input sources). The KX100 provides 15 Band Parametric EQs on the left, right, and center
outputs, a 5 Band Parametric EQ on the sub output, and 7 Band Parametric EQs on the inputs
(one for the microphone inputs and one for the music inputs).
Parametric EQ Parameters
The Parametric EQ algorithm contains the following parameters:
• Band Type (Flat, Low, High, PEQ) - The Type selector allows you to select which type
of filter you would like to use on each band.
1. Flat: Flattens the selected band, essentially turning it off.
2. Low: Manipulates all frequencies below the set frequency (low shelf).
3. High: Manipulates all frequencies above the set frequency (high shelf).
4. PEQ: Manipulates a set range of frequencies, out in both directions from the
center frequency, with the ‘Q’ parameter determining the width.
• Band Gain (-12 dB - +12 dB) - Sets the level of the selected EQ band.
• Band Frequency (20 Hz - 20k Hz) - Selects the center frequency, for each band, at
which the EQ gain or attenuation will be applied.
1. PEQ Frequency Range: 20 Hz - 20000 Hz
2. Low Shelf Frequency Range: 20 Hz - 1000 Hz
3. High Shelf Frequency Range: 1000 Hz - 20000 Hz
• Q (1.0 - 12.0) - This parameter adjusts the width of the PEQ filter. Lower values,
create wider EQ curves (covering a wider range of frequencies) and higher values create
narrower EQ curves (covering a much smaller range of frequencies for more surgical EQ
work). This parameter is only available in bands that are set to the ‘PEQ’ type, as listed
above.
