UAD Powered Plug-Ins Manual - 169 - Chapter 14: Fairchild Tube Limiter Collection
DC Threshold DC Threshold controls the ratio of compression
as well as the knee width. As the knob is turned
clockwise, the ratio gets lower and the knee gets
broader. The threshold also gets lower as the
knob is turned clockwise.
It’s more technically accurate to say that this con-
trol simply changes the knee width, since no mat-
ter where it’s set, the ratio always approaches true limiting eventually. How-
ever, the knee becomes so broad that it becomes more practical to speak of
the ratio changing, because for reasonable amounts of compression (less
than 25 dB), this is the case.
Note: This control is labeled DC Bias on the Fairchild 670 Legacy.
CAL
To calibrate the plug-in to factory specifications (the default value), align the
white “CAL” mark with the black “dot” on the adjustment screw.
Tip: Click the “CAL” text label to return the control to the factory calibrated
position.
OWR
To calibrate the plug-in to the setting used by Ocean Way Recording (the
source unit for the plug-in modeling), align the white “OWR” mark with the
black “dot” on the adjustment screw.
Tip: Click the “OWR” text label to return the control to the Ocean Way Re-
cording position.
Output Gain These controls provide clean, uncolored gain
to the output signals. The available range is
±20 dB. The default value is 0 dB.
Tip: Click the “OUTPUT” text label to return
the control to the default position.
Note: In the Fairchild 670 Legacy this is a stepped control, with each step
being separated by 0.5 dB, and an available range of -18 dB to +6 dB.
