The Audio lter is placed behind the compressor, avoiding unwanted inuences 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 3dB and the part below the center frequency will be cut by 5dB [Fig. A]. Turning
the controller hard left reverses the eect: Below the center frequency there is a boost and above
it there is a cut [Fig. B].
The EQ Freq controller comprehends an array from 20Hz - 2kHz which can be shifted to 200Hz
- 20kHz by pushing the x10 button.
In the linked MS mode shown above it is possible to make dierent settings for the Audio lters
in the M and the S band. Again, the results can be listened to separately by using the Compressed
switches for each channel. However, in Stereo mode, both Audio lters 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 lters it might be necessary to adapt the volume
with the Gain controllers.
