•
RATIO (:1)—sets the ratio of volume reduction applied
to the selected band once the signal falls below the
threshold. The ratio can be set anywhere from 1.00:1 to
∞:1.
When an expander band's ratio is set to ∞:1, it functions as a gate.
•
ATK (ms)—sets the attack time for the selected band. This
can be set anywhere from 0.00 ms to 800 ms.
•
REL (ms)—sets the release time for the selected band. This
can be set anywhere from 50 to 8000 ms.
Multiband Compressor (COMP)
The second multiband processor is the compressor, or "COMP. "
The converse of the expander, the compressor works by
reducing the volume of signals that rise above a specified
threshold.
The compressor contains the following controls:
•
ON/OFF—turns the compressor on (lit) or off (unlit).
•
LO, MID, and HI—selects the desired band for editing.
•
THRE (dB)—sets the threshold for the selected band. The
threshold value can be set from -24 dB to 0 dB.
•
RATIO (:1)—sets the ratio of volume reduction applied to
the selected band once the signal reaches the threshold.
The ratio can be set anywhere from 1.00:1 to ∞:1.
When a compressor band's ratio is set to ∞:1, it functions as a limiter.
•
ATK (ms)—sets the attack time for the selected band. This
can be set anywhere from 0.00 ms to 800 ms.
•
REL (ms)—sets the release time for the selected band. This
can be set anywhere from 50 to 8000 ms.
The Graphic Dynamics Displays
Each multiband processor provides a graphic dynamics display
that shows you how the processor is shaping the level of the
signal for the selected frequency band.
The arrow indicates the threshold point.
The threshold point is indicated by the intersection of two
lines on the display (as shown by the arrow in the illustration
above). In the case of the expander's display, the amount of
gain reduction is indicated by the angle of the line to the left of
the threshold point. In the case of the compressor, the amount
of gain reduction is indicated to the right of the threshold
point.
When there is no threshold point shown on either graphic
display—only a straight diagonal line—no gain reduction will
take place in that band.
A diagonal line means no gain reduction.
