Controls Overview
Most of the controls are associated with one or the other of the compressors,
as opposed to being strictly associated with one channel of input/output (de-
pends on active mode). These controls include Threshold, Time Constant, Bias
Current Balance, and DC Bias.
There are two sets of controls that always work on the left and right signals:
input level and output level. In Lat/Vert mode, left is the mono input, and right
is the stereo input.
Controls on the main panel are all original Fairchild controls, except for the
meter select switch which was used to calibrate bias currents on the original
hardware. The hardware does not have provision for monitoring input/output
or gain reduction levels. For the plug-in, the 'zero' screw-slot control has been
disabled, since the meter cannot become uncalibrated on the plug-in.
Controls on the lower auxiliary panel are original controls, modifications, or
additions as follows:
• The DC Bias controls are original controls, but were on the back of the hard-
• The sidechain link control is a common modification which had been per-
• The Controls Link is a plug-in-only switch.
• The output level controls are an addition for the plug-in.
Parameter
Some hosts use plug-in parameter names in place of the graphical interface,

for example when viewing automation or using control surfaces. Some Fair-
child parameters are named with "A" and "B" instead of "L" and "R" because
that's how the plug-in operates; depending on the mode (i.e. lat/vert), the
channel parameters are not always associated with the left and right chan-
nels.
