UAD Powered Plug-Ins Manual - 490 - Chapter 50: UA 1176 Classic Limiter Collection
The behavior of the Attack knob varies slightly between the models, as de-
tailed below.
UA 1176AE Attack
The 1176AE offers a unique, fixed 10 ms “SLO” Attack mode when this con-
trol is moved to the fully counter-clockwise position.
UA 1176 Rev A and UA 1176LN Rev E Attack
When Attack is in the OFF position the I/O amplifiers remain active while the
compression circuit is bypassed. This enables these models to add 1176
color without dynamics processing. This function is identical to disengaging
all the Ratio buttons.
Note: To avoid unexpected level changes that can result when compression
is disengaged, on these models the OFF text label must be clicked to move the
Attack knob to the OFF position.
UA 1176LN/SE Legacy Attack
The OFF position is unavailable in these plug-ins. To bypass plug-in process-
ing in these models, use the Meter OFF button.
Release Release sets the amount of time it takes the 1176 to return to its initial (pre-
gain reduction) level. The 1176 release time is adjustable from 50 millisec-
onds to 1100 milliseconds (1.1 seconds).
Note that the actual release time varies slightly based on the particular plug-
in model in use and also partially depends on the program material.
The release time is fastest when the Release knob is in its fully clockwise po-
sition, and is slowest when it is in its fully counter-clockwise position. If the re-
lease time is fast, “pumping” and “breathing” artifacts can occur, due to the
rapid rise of background noise as the gain is restored. If the release time is
too slow, however, a loud section of the program may cause gain reduction
that persists through a soft section, making the soft section difficult to hear.
