Limiters
The output limiters restrict the input signal level by compressing its dynamic range when
exceeding a specified threshold. They are most commonly used to prevent clipping,
protecting a system against component or speaker damage. They are enabled by default,
which is the recommended setting for most configurations.
When a limiter is enabled, the following are set:
• Threshold — Activates or deactivates the limiter (subject to attack or release time) after
the signal level exceeds or drops below -0.1 dBFS.
Attack time — Activates the limiter after the signal level reaches or exceeds the
•
threshold level for 2.0 ms.
Release time — Restores the output signal level to normal (unprocessed) levels when
•
the signal level remains below the threshold level for 100 ms.
• Ratio — Reduces the signal level at a 100:1 ratio when the limiter is activated.
Soft knee — Smooths and softens the transition from unprocessed to processed
•
output levels.
To enable or disable a limiter on an output:
1. Click the tab (see
Output
2. For the desired output, click the
and on the previous page) in the appropriate output section.
Mix options
Output mix options determine what audio is output. Options vary depending on device
