Dynamics Processor Meters
The amount of processor gain reduction (GR) and the output signal levels
are shown on the DYNAMICS 1/2 and 2/2 pages, as shown below.
Gain reduction is the amount by which a signal’s level is reduced. The
output signal levels are conventional level meters which work from
bottom-to-top. The GR level meter is inverted and works from
top-to-bottom.
For compression, expansion, companding, and ducking, the GR meter
operates when the processor is active, that is when it has been triggered by
the KEY IN signal, and it shows the amount of signal level reduction.
For a gate, the processor is active when the input signal is below the
threshold. So the GR meter operates when the input signal is below the
threshold and also when there is no input signal.
Dynamics Graph
The dynamics graph gives you a visual indication of how the parameters of
the dynamics processor will effect the signal as it passes through. The
horizontal axis of the graph indicates the input signal. The vertical axis
indicates the output signal:
When the dynamics graph is a straight line at 45° from the bottom left
corner of the graph, it indicates that the dynamics processor will have no
effect on the input signal.
