Operating Manual - nX, nXe, and nXp Power Ampliers
Release Time - The rate (in ms/dB) at which the Compressor attenuation will return to normal, once the signal falls
below Threshold.
Link Group - Group to which all parameters are assigned, to facilitate simultaneous adjustment to multiple Compres-
sors in the system.
Attenuation Bus: All Compressors assigned to the same Attenuation Bus will apply the largest amount of attenuation
on any of the assigned Compressors. This can be used to facilitate "stereo" (or similar) operation of multiple Compressors.
Show Meter On Graph - Overlays the Input/Output level meters on the graphical display.
Detector - Selects between PEAK and AVERAGE operation of the Detector (see below).
Peak Detector - Setting the detector to Peak means that the peak level of a signal is used to trigger the Compres-
sor. In Peak detect mode, Attack and Release times are both adjustable
Average Detector -
Setting the detector to Average means that the average level of a signal is used to trigger the
Compressor. Instead of separate Attack and Release controls, the Average Rate controls the speed at which the compressor functions.
Autoleveler
The Auto Leveler is a dynamics processor used to automatically boost or
cut a signal to a user-dened target level. The Target Level is the primary setting
in the Autoleveler, as it determines the constant level to which an input is boost
or cut. The Autoleveler can be used in situations such as speech re-enforcement,
where an unknown source level needs to be maintained at a specic output level.
For example, a podium microphone where different speakers will be presenting
may have an auto-leveler applied to ensure that strong or soft speakers' voices
are amplied appropriately. The controls for the auto leveler are split into two
categories, Basic and Advanced. It is recommended you start with the basic
controls, and if ne tuning is required, use the advanced controls. Warning:
Depending on the settings, it is possible to apply up to 27dB of gain with the
auto leveler.
Basic Parameters:
Target Level - The desired continuous output level of the signal.
Action - Sets the Ratio, Hold Time, and Gain Change Rates (see below
for denitions). These settings are general starting points for how the auto leveler
should behave. Action can also be user dened under Advanced Controls, with
three drag points available for a more visual adjustment.
Action Ratio Hold Time Gain Increase Gain Decrease
Aggressive 10:1 0 Seconds 20 ms/dB 5 ms/dB
Normal 4:1 1 Second 50 ms/dB 10 ms/dB
Gentle 2:1 2 Seconds 100 ms/dB 20 ms/dB
Maximum Gain - This is the total amount of gain the auto leveler may apply before it stops affecting the signal.
Maximum Gain controls the Threshold Below Target using the following formula:
Threshold Below Target = Max Gain ÷ ( ( 1 ÷ ratio) - 1)
