D3 Compressor Controls
The Compressor icon, which represents a com-
pression curve, acts as a three-state switch for en-
abling, disabling, or bypassing the compressor. Its
current state is indicated by the icon’s color.
• White indicates enabled. In this state the com-
pressor is active and using available DSP
resources.
• Black indicates disabled. In this state, the
compressor is not using DSP resources.
• Gray indicates bypassed. In this state the com-
pressor is not active, but is still using available
DSP resources.
To disable the compressor:
 Start key-click (Windows) or Control-click
(Mac) the icon. When the compressor is dis-
abled, the icon is black.
To re-enable the compressor:
 Click the icon. When the compressor is enabled,
the icon is white.
To bypass the compressor:
 Click the icon a second time. When the com-
pressor is bypassed, the icon is grey.
If you are using the Compressor/Limiter plug-in,
which allows you to use either the compressor or
the limiter (but not both simultaneously), you must
disable one module by Start key-clicking the icon
(Windows) or Control-clicking it (Mac) before
you can enable the other.
Ratio
Ratio sets the compression ratio. If the ratio is set
to 2:1 for example, it will compress changes in sig-
nals above the threshold by one half. The range of
this control is from 1.5:1 (very little compression),
to 10:1 (heavy compression, bordering on limit-
ing).
