Parameter Window Features
Transfer Curve Graph
The transfer curve graph displays the threshold level as a graphical element that you can position with
the mouse.
Transfer Curve Meter
In the Live Mode, this meter depicts the paging signal's input level, so you can set the threshold above
ambient noise. This feature can be toggled off and on by selecting the [Options>Transfer Curve] menu
option. Its default status is on.
Note: Software performance may be reduced if a large number of meters are active.
You can turn off the threshold meter or the gain reduction meter, or both, from
the [Options] menu.
Threshold Slider
The position of the threshold slider corresponds to the setting in the threshold control. Use the mouse
to drag this slider left or right along the top edge of the threshold graph. The threshold level will change
accordingly.
Gain Reduction Meter
This meter indicates the total gain reduction you are achieving on the ducked signals with the current
processor settings. This feature can be toggled off and on by selecting the [Options>Gain Reduction
Meter] menu option. Its default status is on.
Threshold Exceeded Indicator
Signal level has exceeded the threshold
Signal level has not reached the threshold
This indicator is lighted in yellow when the
input signal to the processor block exceeds the
specified threshold.
Attenuation
This controls the amount of gain reduction applied to the ducked signals when the paging signal
exceeds the threshold. You can change this value by clicking on the spin buttons or by typing in a
specific value ranging 1 dB to -INF.
Threshold
This controls the gain level the paging signal must reach before the processor attenuates the ducked
signals. You can change the value by clicking on the spin buttons or by typing in a
specific value ranging from +20 dB to –60 dB.
