Operating Manual - nX, nXe, and nXp 150W/75W Power Amplifiers
Link Group
- Group to which all parameters are assigned, for simultaneous adjustment to multiple limiters
Attenuation Bus
: All compressors assigned to the same attenuation bus will apply the largest amount of current gain reduction
from any one of the assigned compressors. This is typically used used for tracking compression across stereo signals.
Show Meter On Graph
- Overlays the input/iutput level meters on the graphical display.
Detector Type
- This selects between peak or average detector operation.
Peak Detector -
Setting the detector type as peak means that only the peak level of a signal is used to trigger the compres
-
sor. Peak detect is typically used for limiter applications where any signal level above a certain point is undesireable. In peak
detect mode, attack and release times are both adjustable.
Average Detector -
Setting the detector type to average means that a computed average signal level is used as the compressor
trigger instead of peak levels. The averaging detector is more musical and natural sounding and typically used to "thicken" vocals.
When using the average detector, attack and release controls are replaced with a single average rate control which adjust the speed
at which compressor action occurs.
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 defini
-
tions). 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:
