Operating Manual - nX, nXe, and nXp Power Amplifiers
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 Compressors 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 Compressor. 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-defined 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 specific 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
amplified appropriately. The controls for the auto leveler are split into two cat
-
egories, Basic and Advanced. It is recommended you start with the basic controls,
and if fine 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
definitions). These settings are general starting points for how the auto leveler
should behave. Action can also be user defined under Advanced Controls, with
three drag points available for a more visual adjustment.

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
