Compressor - Universal Audio Ampex ATR-102 Manual

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:
Threshold determines how much compression will occur. When the input sig-
Compressor
Threshold
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.
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 This makeup gain control increases the signal level out of the compressor to
Gain
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:
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.
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.

The compressor precedes the limiter (see
If the limiter is also enabled, this gain is applied before the limiter stage.
