Gain Reduction Limiter

A specialty of the xpressor 500 is the Gain Reduc-

tion Limiter for the control voltage. This limiter is not

placed in the audio path where you would usually

nd it, but in the control path of the compressor instead.

When activated, it limits the control voltage according to the

setting of the GR Limit controller. This means: No matter how

high the input level might become – the 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 the xpressor 500, this function is always active and

does not need a switch of its own.
