Audio Filter
The audio filter is placed behind the compressor in order to avoid unwanted influences on the
detection circuit of the dynamic section.
If the EQ gain controller is turned hard right, the signal rates above the selected center frequency
will be boosted by 3 dB and the part below the center frequency will be cut by 5 dB [Fig. A]. Turn-
ing the controller hard left reverses the effect: Below the center frequency there is a boost and
above it there is a cut [Fig. B].
The EQ frequency controller comprehends an array from 20 Hz - 2 kHz which can be shifted to 200
Hz - 20 kHz by pushing the x10 button.
In linked M/S mode as explained above it is possible to make different settings with the audio
filters in the M and the S band. Again, the results can be listened to separately by using the com-
pressed switches for each channel. However, in stereo mode, both audio filters should be set to
the same values in order to avoid unwanted shifts in the stereo spectrum.
Note: Depending on the settings of the audio filters it might be necessary to adapt the volume
with the gain controllers.
