D3 Limiter Controls
The Limiter icon, which represents a limiter curve,
acts as a three-state switch for enabling, disabling,
or bypassing the limiter. Its current state is indi-
cated by the icon’s color:
• White indicates enabled. In this state, the limiter
is active and using available DSP resources.
• Black indicates disabled. In this state, the limiter
is not using DSP resources.
• Gray indicates bypassed. In this state, the limiter
is not active, but is still using available DSP
resources.
To disable the limiter:
 Start key-click (Windows) or Control-click
(Mac) the icon. When the limiter is disabled, the
icon is black.
To re-enable the limiter:
 Click the icon. When the limiter is enabled, the
icon is white.
To bypass the limiter:
 Click the icon a second time. When the limiter
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.
Limit LED
When lit, the Limit LED indicates that limiting is
being applied. When unlit, limiting is not being ap-
plied.
Threshold
This sets the threshold level. Signals that exceed
this level will be limited. Signals that are below it
will be unaffected. A setting of 0 dB is equivalent
to no limiting. The range of this control is from
–24 dB to 0 dB.
Using the Side-Chain Input in
Focusrite D3
The side-chain is the split-off signal used by a
plug-in's detector to trigger dynamics processing,
and is generally drawn internally from the input
signal. However, some plug-ins (such as the Fo-
cusrite D3) let you switch between internal and ex-
ternal side-chain processing.
