UAD Powered Plug-Ins Manual - 370 - Chapter 36: Neve 33609 Compressor
Compressor
Controls in this section only function when the compressor is enabled with the
“compress In” switch (the Power switch must also be on).
Note: The compressor precedes the limiter (see “Signal Flow” on page 368 ).
Compressor
Threshold
Threshold determines how much compression will occur. When the input sig-
nal exceeds the threshold level, the compressor engages. A smaller value re-
sults in more compression. The available range is from –20 dB to +10 dB, in
2 dB increments.
Compressor
Recovery
Recovery (release) is the time it takes for the compressor to stop processing af-
ter the signal drops below the threshold value. The available values (in milli-
seconds) are 100, 400, 800, 1500, a1, and a2.
The automatic settings (a1 and a2) are program dependant. The value for a1
can be as fast as 40ms, but after a sustained period of high signal level, the
period is
≈800ms. The value for a2 can be as fast as 150ms, but after a sus-
tained period of high signal level, the period is ≈1500ms.
Compressor
Gain
This makeup gain control increases the signal level out of the compressor to
compensate for reduced levels as a result of compression. The available
range is 0 to +20 dB, in 2 dB increments.
Make sure to adjust the Gain control after the desired amount of compression
is achieved with the Threshold control. The Gain control does not affect the
amount of compression.
Note: If the limiter is also enabled, this gain is applied before the limiter stage.
Ratio This control determines the compressor ratio. The available values are 1.5:1,
2:1, 3:1, 4:1, and 6:1, selectable in discrete increments.
Compressor In This toggle switch enables the compressor portion of the plug-in. The compres-
sor has no effect unless this switch is in the “In” (down) position.
