UAD Powered Plug-Ins Manual - 185 - Chapter 17: LA-3A Compressor
LA-3A Controls
Background For detailed information about compressors, see “The LA-2 captures one of
the earliest Teletronix examples. This exceedingly rare unit preceded the LA-
2A by a few years and incredibly, still has the original T4A fully intact. The LA-
2 provides the slowest response and a unique “mellowed” sound due to 50
years of luminescent panel aging inside the T4 module. Use the LA-2 with le-
gato tempos and your most vowel-like sources for a transparency and sublime
mood unlike any other compressor.” on page 470

Comp/Lim This switch changes the characteristics of the compressor I/O curve. When
set to Compress, the curve is more gentle, and presents a low compression ra-
tio. When set to Limit, a higher compression ratio is used.
Gain The Gain knob adjusts the output level (by up to 50 dB). Make sure to adjust
the Gain control after the desired amount of compression is achieved with the
Peak Reduction control. The Gain control does not affect the amount of com-
pression.
Peak Reduction This control adjusts the amount of gain reduction, as well as the relative
threshold. A Peak Reduction value of 0 yields no compression. Rotate this con-
trol clockwise until the desired amount of compression is achieved (to monitor
the Peak Reduction, set the VU Meter to Gain Reduction). The Peak Reduction
should be adjusted independently of the Gain control.
Meter This switch sets the mode of the VU Meter and also disables the plug-in. When
set to Gain Reduction, the VU Meter indicates the Gain Reduction level in dB.
When set to output, the VU Meter represents the output level (the output meter
is not calibrated).
When in the Off position, the plug-in is disabled and UAD DSP usage is re-
duced.
Note: (UAD-2 only) UAD-2 DSP usage is reduced only when DSP LoadLock is
disabled. If DSP LoadLock is enabled (the default setting), setting the switch to
Off will not reduce DSP usage.
Stereo
Operation
Phase-coherent stereo imaging is maintained when the LA-3A plug-in is used
on a stereo signal.
