Desired target level for the levelling process.
Reference Level for the Transient Processor
and Leveller
Determines the maximum gain change applied
by the Transient Processor when there are fast
input level changes. Large range values are
reducing the dynamic range, especially in
combination with the transient program "hard"
This parameter describes the characteristic of
gain change by the transient processor. It has
to be chosen dependent on your program
genre. If there are just a few level changes or
you want to keep the original dynamic range
best (e.g. classical music), you have to choose
"soft". For mixed program "mid" should be best
in most cases. And for live venues (sport etc.)
with frequent unexpected level changes the
adjustment "hard" is required.
If the input level falls below this threshold level,
the gain change of the AGC freezes
immediately (transient processor still active).
After appr. 20 seconds input level below
silence gate the current gain change is slowly
moving to the longterm average gain.
Describes the time of development for the
AGC to reach the maximum possible gain
change (range value).
The ratio of gain change should never be
faster then 3 seconds for 1 dB!! We are
recommending a setting of 4...5 seconds for
1dB gain change by the AGC. Therefore the
AGC time is basically determined by the AGC
range value. A range setting of 10 dB requires
a time setting of minimum 40 seconds.
Determines the maximum gain change applied
by the AGC.
AGC Range must be bigger then the expected
difference between the average input level and
the operating level.
If there is for example an average input level of
-23dBFS and your OP-Level is -18dBFS, the
AGC needs at least a range of 5dB. In most
cases an AGC range of 10dB is a good choice
Compresses the audio signal => increase
of loudness, complicated settings are not
necessary because there are diverse
adaptive control algorithms, which can be
accommodated in an optimal way with the
parameter COPM program
