Default Range Description
This indicator signals in dB by how much the
limiter reduces the signal level. A red bar that
increases from the right to the left indicates the
degree of gain reduction.

The THRESHOLD parameter defines the level
value at which the limiter sets in. Signal levels
below the threshold will pass through the limiter
unaffected. As soon as the signal level reaches or
exceeds the threshold, signal limiting sets in.
Generally, the THRESHOLD of the limiter should
be set some dB higher than the compressor’s
threshold to effectively limit high level peaks.
Entering the threshold value is possible in dBu or
V. The value can be entered in either box and will
automatically be converted in the other.
5 ms 0...50 ms ATTACK defines how fast the gain is reduced
after the signal exceeds the threshold level.
250 ms 10...1000 ms RELEASE defines how fast the output signal
returns to its normal level once it drops below
the threshold.
BYPASS activates (not engaged) or deactivates
(engaged) the Limiter, which allows for quick A /
B comparison between the limited and unlimited
audio signal.
