LIMITER
A Limiter is used when the output signal must not exceed a specific peak level, independent of how
much the input level rises. Short attack times effectively limit overshoots. Limiters are often used as protection for the
components following them an audio chain, i.e. to prevent an amplifier from clipping or protect loudspeaker systems
against mechanical damage.

-9.0 to +21.0 dBu
or
0.275 to 8.696 V
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. 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 to 50 ms
ATTACK defines how fast the gain is reduced after
the signal exceeds the threshold level.
100 ms
10 to 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.
