Gain Reduction Limiter
A specialty of the mpressor 500 is the Gain Reduction
Limiter. This limiter is not placed in the audio path
where you might expect it, but in the control path of
the compressor instead.
When activated, it limits the control voltage according to the
setting of the GRL controller. This means: No matter how high
the input level might become – the total amount of gain re-
duction will never exceed the value you have set.
Just think about the GRL as a second threshold controller:
While the ‘regular’ threshold controller tells the compressor
when to start working, the GRL controller tells it when to com-
press no further.
Loud parts in an arrangement can keep their dynamics, as
they will not be compressed beyond the limit of the Gain Re-
duction Limiter.
Note:
In order to avoid GRL activity, just turn its controller fully
counter-clockwise.
