Dynamics - Extron electronics DMP 64 User Manual

Dynamics

A dynamics processor alters the dynamic
range, the difference between the loudest to
the quietest portions of an audio signal. Each
input channel provides two dynamics processor
blocks that, when inserted, provide one of four
types; AGC, Compressor, Limiter or a Noise
Gate processor.
To insert a processor into an empty block,
select from the processor menu. The menu
appears when the block is double-clicked, or is
accessed from a context menu that appears when the block is right-clicked.
Once the processor has been inserted, individual processor parameters can be changed in
the dialog box, accessed by double-clicking the processor block.
All parameters are displayed in a text box and have a resolution to 0.1 increments.
Parameters can be set by direct entry in the text box to replace existing text, then pressing
Enter or tabbing/clicking to another area. Threshold, gain/attenuation, target, and ratio
parameters have adjustment points on the graph display. Use the mouse to click + drag
the graph point to the desired destination/value. All time values have a horizontal slider
allowing adjustment in 1 ms increments by either a click + drag of the slider handle, or
focusing on the slider, then using left/right arrow keys (Page Up/Down keys adjust in
increments of 10 ms).
The table below lists each dynamics processor type, parameters, and factory default
settings.
