LFE Enable
(Pro Tools HD Systems Only)
The LFE Enable button (located in the Options
section) is on by default, and enables plug-in
processing of the LFE (low frequency effects)
channel on a multichannel track formatted for
5.1, 6.1, or 7.1 surround formats.

To disable LFE processing, deselect this button.
The LFE Enable button is not available if
the plug-in is not inserted on an applicable
track.
Dynamics Graph Display
The Dynamics Graph display—used with the
Compressor/Limiter and Expander/Gate plug-
ins—shows a curve that represents the level of
the input signal (on the x–axis) and the level of
the output signal (on the y–axis). The orange
vertical line represents the threshold.
Use this graph as a visual guideline to see how
much dynamics processing you are applying.

The Compressor/Limiter and Expander/Gate
plug-ins also feature an animated, multi-color
cursor in their gain transfer curve displays.
The gain transfer curve of the Compressor/Lim-
iter and Expander/Gate plug-ins shows a mov-
ing ball cursor that shows the amount of input
gain (x-axis) and gain reduction (y-axis) being
applied to the incoming signal.
