Chapter 26: LA-3A Compressor
LA-3A Controls
Background
For detailed information about compressors, see
“Compressor Basics” on
page 281
.
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
(
page 74
) 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.
