INPUT COMPRESSOR
The input compressor has four controls: Attack, Release, Threshold and Ratio. Click on
the dropdown list to adjust each parameter. Click the Bypass button to turn it off.
About Compression: A compressor is used to reduce or limit transient peaks in a signal.
As the input level to the compressor increases, the output level increases linearly until the
threshold point is reached. After that point, the output level no longer increases linearly,
but increases at a reduced rate that is determined by the ratio setting.
• Threshold: This control determines the level at which the compressor begins to act on
the incoming signal. It is calibrated in decibels, with a range from –-40.0 dBu to 17 dBu.
• Attack: This determines how fast the compressor reacts once the threshold has been
exceeded. It is calibrated in milliseconds, with a range from 1 ms to
90 ms.
• Release: This determines how fast the compressor turns off once the signal falls below
the threshold. It is calibrated in milliseconds, with a range from 10 ms to 2500 ms (2.5
seconds).
* Ratio: This determines the change in output level as a function of the change in input
level, once the threshold has been exceeded. It is calibrated in decibels, with a range
from 1.2:1 (off) to 30:1.
