Filter curves of several outputs
2) To adjust the low pass filter, enter the cut-off
frequency in the field "Frequency [Hz]" under
"Low Pass filter" and from the list "Slope"
select the filter characteristic or "Bypass" if
the filter is not to be used (details about the fil-
ter characteristic chapter 5.4.5).
3) For the filter characteristics "Custom..." to
adjust additional parameters click one of the
two buttons "Edit". Then the window "Edit
custom filter High / Low Pass ..." (
opens.
Contrary to the presentation of the fre-
quency response in the main window of the
output channel ( chapter 6.4.5.6), in this
case only the change of the frequency
response by the high pass filter and low pass
filter is shown.
On the top right of the diagram it is possi-
ble to select the presentation of magnitude
frequency response "Mag" or phase fre-
quency response "Phase".
Depending on the filter characteristic
"Custom..." selected, additional input fields
for further parameters are inserted. Via the
buttons "ButtW" and "L-Riley" the filter char-
acteristics Butterworth and Linkwitz-Riley
may be preset, if possible, as a basis for an
individual adjustment.

6.4.5.5 Sound control

Under "EQ" it is possible to adjust the 5 inde-
pendent filters of the output channel, as already
described for the input channels (
6.4.4.4).

6.4.5.6 Frequency response

The upper range of the view shows the fre-
quency response of the output channel, depend-
ing on the adjustment of the high pass and low
pass filters, the sound control and the output
amplification.
On the top right of the diagram it is possible
to select between the presentation of magnitude
frequency response "Mag" and phase frequency
response "Phase".
The buttons below the diagram allow to
define if only the adjustments of the output chan-
nel "Out only" are to be shown or also the adjust-
ments of the input channel A "Out + In A" or if the
input channel B "Out + In B" are to be consid-
ered for the presentation.
The curves of the other output channels
may in addition be inserted or extinguished in the
diagram via the buttons named accordingly
( fig. 19). Thus, it can e. g. be shown how the
magnitude frequency responses of the channels
of a crossover network completement one
another.
When the button "Show cursor" is clicked, a
graphical reference point (
,
shown next to the curve ( fig. 16) for each fil-
ter for the presentation of a magnitude frequency
response. By means of the mouse the filters can
now graphically be adjusted by moving these
points with regard to frequency and level boost-
ing/attenuation (if admitted by the filter type
selected).
When the button "Show cursor" is clicked
again, the reference points will disappear.

6.4.5.7 Compressor

To change the parameters of the compressor,
move the corresponding control under "RMS
Compressor" with the mouse or, with a control
selected, on the keyboard with the arrow keys or
the scrolling keys. (Details about the function
and the parameters of the compressor
ter 5.4.7)
