Programming details
The control curve is defined by up to 6 points, known
as “reference points”. In the default software configu-
ration, 2 reference points are already defined, namely
only the two end-points, “L” and “H”; see the next
screen image.
The following section applies to “any” mixer to which
we wish to assign a non-linear curve characteristic.
The examples shown in the following section are
merely illustrative, however, and they do not rep-
resent real-life mixer curves.
Setting reference points
When you move the transmitter control assigned to
the mixer input – here control function 8 – a vertical
line in the graph follows the movement between the
two end-points. The current control position is also
shown numerically on the “Input” line. The point at
which this line intersects with the curve in question
is named the “Output” and can be varied between
-125 % and +125 % by setting reference points; see
further below. This control signal acts on the mixer
output.
In the above example, the transmitter control is on
input 8 at -50 % of control travel. The output signal
continue to show 0 %, however, since no value has
yet been entered.
Up to four additional reference points can be set
between the two end-points “L” and “H”, although the
distance between neighboring reference points must
not be less than approx. 25 %.
Move the transmitter control of the control channel
you have selected – in this example the left of the two
proportional sliders fitted to the centre console (“Sl1”).
While a question mark is displayed in the Point line,
you can set the next reference point by pressing the
central SET button of the right-hand four-way button:

When you now briefly tap the center SET key of the
right four-way button, the “?” is replaced by a point
number and the value field to the right is activated,
i. e. presented in inverse video:
–45%
0%

Using the selection keys on the right four-way button
you can now change the point value within a range of
±125 %, e. g.:
–45%
+50%

8 10
+50%

Note:
If the stick does not coincide with the exact reference
point, please note that the percentage value on the
“Output” line always relates to the current stick posi-
tion.
Continue in this way to set other reference points.
Note that the order in which you generate the (maxi-
mum) four reference points between end-points “L”
and “H” is irrelevant, since the reference points are
continuously renumbered automatically from left to
right as they are entered:
+35%
–55%

Erasing reference points
To erase one of the reference points between “L” and
“H”, use the transmitter control in question to move
the vertical line onto or into the vicinity of the refer-
ence point in question. The reference point number
and associated reference point value are shown on
the “Point” line. If necessary, activate the Value field
by pressing the central SET button of the right-hand
four-way button.
With the Value field now highlighted, press the two
Select buttons  or  of the right-hand four-way
button (CLEAR) simultaneously.
The selected reference point is erased, and the num-
bering of the remaining reference points is updated
as required. Briefly tap the center ESC key of the left
four-way button to complete the procedure.
Note that the reference points “L” and “H” cannot be
erased.
Changing reference point values
To change reference point values, use the associ-
ated transmitter control to move the vertical line onto
the point you wish to change: “L”, 1 … 4 or “H”. The
number and current curve value of this point are dis-
played. After activating the value field on the “Point”
line by briefly tapping the center SET key, use the
selection keys on the right four-way button to change
the current curve value shown in the highlighted field.
The possible range is -125 % to +125 % and changes
do not affect neighboring reference points. Briefly
tap the center ESC key of the left four-way button to
