UAD Powered Plug-Ins Manual - 489 - Chapter 50: UA 1176 Classic Limiter Collection
1176 Controls
Each 1176 plug-in variation has the same control set, so they are only de-
tailed once. The parameter descriptions below apply to all models unless oth-
erwise noted.
Input Input adjusts the amount of gain reduction as well as the relative threshold.
Rotate the knob clockwise to increase the compression amount.
Like the original hardware, the label values are somewhat arbitrary; the
knobs are not calibrated to any particular dB values and levels will vary be-
tween the various plug-in models. Even when the Input knob is set to “
∞” sig-
nals can still pass into the processor and be compressed.
Note: In the UA 1176 Limiter Collection plug-ins, increasing Input will in-
crease distortion.
Output Output determines the final output level of signal leaving the 1176. Once the
desired amount of limiting or compression is achieved with the use of the Input
control, the Output control can be used to make up any gain lost due to gain
reduction.
To monitor the Output level, set the VU Meter to +8 or +4. The Output control
does not affect the amount of compression.
Note: In the 1176 Limiter Collection plug-ins, increasing Output will increase
distortion.
Attack Attack sets the amount of time it takes the 1176 to respond to an incoming sig-
nal and begin gain reduction. The 1176 attack time is adjustable from
20 microseconds to 800 microseconds (both extremely fast).
The attack time is fastest when the Attack knob is in its fully clockwise position,
and is slowest when it is in its fully counter-clockwise position. When a fast at-
tack time is selected, gain reduction kicks in almost immediately and catches
transient signals of very brief duration, reducing their level and thus “soften-
ing” the sound.
Slower attack times allow transients (or partial transients) to pass before lim-
iting or compression begins on the rest of the signal. Note that the actual at-
tack time varies slightly based on the selected ratio and the particular plug-in
model in use. Lower ratios will maintain the fastest attack times.
