005: Stereo Limiter
On-screen graphic, 005 Stereo Limiter
The Limiter regulates the input signal level. It is similar to
the Compressor, except that the Limiter compresses only
signals that exceed the specified level to lower unnecessary
peak signals. The Limiter applies a peaking-type EQ to the
trigger signal (which controls the degree of the Limiter
effect), allowing you to set any band width to be covered.
This is a true stereo effect; you can link left and right
channels, or use each channel individually.
ENVELOPE
Source [Input, FX Control 1, FX Control 2]
This selects the control signal for the limiter: the input
signal, FX Control Bus 1, or FX Control Bus 2. For more
information, see “Source” on page 762.
Select [L/R Mix, L Only, R Only, L/R Individually]
This determines how the left and right channels of the
selected
Source are used. Note that this parameter applies
only to the control signal; the effect always processes both
channels of the input signal in stereo. For more information,
see “Select” on page 763.
L/R Mix is generally the best choice for stereo signals; this
will cause the limiting to be applied equally to both
channels, based on the combined volumes of the left and
right channels.
L Only and R Only use only the selected channel for
controlling the limiter; the other channel is ignored.
L/R Individually essentially splits the stereo limiter into
two separately controlled mono limiters. When processing
stereo signals, this will cause the stereo image to shift.
FX Control Trim [0…100]
This adjusts the level of the FX Control Bus inputs.
Side Chain Monitor [Check-box]
This lets you listen directly to the control signal (as selected
by the
Source parameter) through the sidechain EQ. See
“Side Chain Monitor” on page 763.
SIDE CHAIN EQ
This EQ applies only to the control signal, and not to the
main audio path. Use it to alter the response of the limiter so
that it reacts (or does not react) only to specific frequencies.
For instance, if you want the limiter to ignore cymbal
crashes, adjust the sidechain EQ to reduce the gain of
frequencies specific to the cymbals. While doing so, it may
help to turn on the
Side Chain Monitor switch, so that you
can listen as you hone in on the desired frequencies.
Side PEQ On [Check-box]
This lets you enable and disable the sidechain EQ–handy for
comparing its effect.
Fc [Hz] [20…12.00k]
Sets the EQ center frequency for the control signal.
The red marks show the Threshold setting.
These lights show the relation of the control input to the Threshold, in real-time.
Under (green) means the input is below the Threshold, and so the signal will pass through unchanged.
Over (red) means that the input is above the Threshold, and so the signal will be limited.
This meter shows the amount of gain reduction, in
real-time. To show that the gain is being reduced,
the meter moves in the opposite direction from the
Input meter.
Vertical axis: Output from the limiter
Horizontal axis: Input to the envelope control
This meter shows the control signal, in real-time,
including the effect of the Side Chain EQ.
The red marks show the Threshold setting.
The yellow line shows the output level, relative to the input level.
This will change according to the Ratio and Threshold settings.
Input above the Threshold will be compressed. In the example shown here, a
–10 dB input will result in –20 dB output.
This meter shows the output level, in real-time.
