Dynamics (Dyn) - Extron electronics DMP 128 User Manual

Additional Controls
• Double Talk Echo Reduction – sets the amount of echo reduction applied during
double-talk. The range is 0.0 to 20.0 dB in 0.1 dB increments.
Default is 15.0 dB.
• Comfort Noise – sets a comfort noise level in dB to eliminate states of complete
silence, which could be perceived as a failed connection. The range is 0.0 to 40.0 dB in
0.1 dB increments.
Default is 0.0 dB which turns comfort noise off.

Dynamics (DYN)

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.
Once a processor is inserted, double-click the
processor block to change individual processor
parameters in the dialog box. For comparison,
click Bypass to bypass the 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 press
<Enter>, or <Tab>, or click 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 or value. All time values have a horizontal slider
allowing adjustment in 1 ms increments. Either click+drag the slider handle, or focus
on the slider and use the left or right arrow keys (the <Page Up> and <Page Down> keys
adjust in increments of 10 ms).
The table below lists each dynamics processor type, parameters, and factory default
settings for the processor.
