The following types of processors are available in both limiters and compressors.
§ Soft Knee – These processors provides a gradual transition from uncompressed signal to
compressed signal. These processors consume a higher percentage of total DSP than
those without the soft knee option.
§ Stereo – These processors allows you to preserve a stereo image by placing two blocks
that function as a single processor on two different channels. Both processor channels react
with identical gain reduction when the input to either channel exceeds the threshold setting.
These processors consume a higher percentage of total DSP than mono processors.
Parameter Window Features
This section explains the features and parameter controls of compressors and limiters using the SFT LIM
as the example, as pictured in figure 32 on the previous page. All the processors covered in this section
are very similar in operation. Any differences between their features and functionality are noted where
applicable.
Transfer Curve Graph
The transfer curve graph displays the threshold level and compression ratio settings as graphical
elements that you can position with the mouse. The resulting transfer curve represents the change in
the signal output level.
Transfer Curve Meter
When you are in Live Mode, this meter depicts the signal's input level and relative output level, so you
can monitor the processor's effect on the current program material. This feature can be toggled off and
on by selecting the [Options>Transfer Curve Meter] menu option. Its default status is on.
Note: You may experience reduced software performance if you have a large number
of meters active overall in the System Processor software. You can selectively
turn off either the transfer curve meter or the gain reduction meter, or both, from
the [Options] menu.
Threshold Slider
The position of the threshold slider corresponds to the setting in the threshold control. You can drag
this slider with the mouse, left and right along the top edge of the transfer curve graph, to change the
threshold setting.
Ratio Slider
The position of the ratio slider corresponds to the setting in the ratio control. You can drag this slider
with the mouse, up and down along the right-hand edge of the transfer curve graph, to change the
ratio setting.
Gain Reduction Meter
This meter indicates the total gain reduction you are achieving on the input signal with the current
processor settings. This feature can be toggled off and on by selecting the [Options>Gain Reduction
Meter] menu option. Its default status is on.
Gain Controls
Use the gain controls to adjust the input and output gain levels. The range of available gain values is
between –12dB and +12dB in 0.5dB increments, with 0dB as the default value. You can change the
value using the conventions explained in the Faders section on page 31.
