Offset - (Std. Prog Mixer)
The Offset parameter defines the position of the 
Master where the mixer changes directions. The Offset 
automatically defaults to a channel’s center position or 
0 (zero). For example, if the Rudder is the Master, the 
Offset automatically defaults to the center stick position 
(no rudder input). Since the Offset is at the center, 
moving the rudder stick to the left of center causes a mix 
in one direction while moving the rudder stick to the right 
of center causes a mix in the other direction. Directions 
correspond to the upper and lower percentages for Pos0 
and the upper and lower percentages of Pos1. The amount 
of mix and actual direction the slave moves is determined 
by the Pos0/Pos1 values. The Offset applies to both Pos0 
and Pos1 settings.
You can change the Offset by highlighting and selecting 
Offset, then adjusting either a positive (+) or negative 
(-) value. A positive percentage moves the offset in one 
direction from center while a negative percentage moves 
the Offset in the other direction from center.
Available Switches - (Std. Prog Mixer)
There are 3 switches you can always use to switch 
between Pos0 and Pos1 settings. (If the upper and lower 
settings for Pos0 or Pos1 are left at 0%, you can turn the 
mixer on and off with the switch). They include the Rudder 
D/R switch, Butterfly Switch, Rudder D/R switch and the 
AUX4 switch. In addition, if Flight Modes are activated 
in the Devic.SEL function, then 5 more switches may 
be selected: Cruise, Speed, Thermal, Launch and Land, 
which correspond to the 3 positions of the Flight Mode 
switch.
To select a switch that will alternate between the Pos0 
and Pos1 values, highlight and select the switch name 
and it will toggle between Pos0 and Pos1. Set the desired 
switch(es) to Pos1.
CLR Button - (Std. Prog Mixer)
Pressing the CLR button while a modifiable parameter is 
selected resets the parameter to its default value.
Note: Pressing the CLR button when either the 
Master or Slave is highlighted Inhibits the entire 
mixer, making it no longer functional. 
LIST Button - (Std. Prog Mixer)
Press the LIST button to return to the FUNCTION List, or 
rotate the rotary selector until 
LST appears next to LIST 
and select it to return to the SYSTEM Menu.
ENT Button - (Std. Prog Mixer)
Pressing the ENT button returns to the Main Display. 
TO INHIBIT A MIXER (TURN IT OFF ENTIRELY)
Highlight either the Master or Slave and press the CLR 
button to completely disable a mixer.
There are 2 Multi-Point Programmable Mixers in the 
GLID system. They are Prog.Mix1 and Prog.Mix2. They 
differ from the standard mixers in that they allow a non-
linear mix response from the Master to the Slave. This is 
possible because the mixer uses 7 points to define how 
the slave channel moves as the Master is moved. As the 
Master comes across each point, the Slave response 
can be defined in terms of deflection and direction 
independent of other point settings. This results in 
extreme flexibility in the movement of the Slave channel 
relative to the Master channel.
Master Channel - (Multi-Point Mixer)
This is the Master channel that receives input from the 
pilot. To select the Master channel, highlight and select 
this parameter to obtain a list of channels. Then select the 
Master channel from the list.
There are 4 channels that appear more than once. They 
are Flap, Aileron, Elevator and Rudder. Since these 
channels can be influenced by Dual Rate, Exponential, and 
Throttle Curve settings, they appear in the list twice - once 
where the D/R and EXP settings are in effect and again 
where the D/R and EXP settings are ignored. The second 
time they are listed, there is a special designator to 
indicate that these channels can also be used as a Master 
while bypassing any Dual Rate and Exponential settings 
that may be associated with them. They are designated 
by a “#” (pound sign) in front of the name - #FLP, #AIL, 
#ELE, and #RUD. When one of these channels is selected 
as the Master, all D/R, EXP and Curve settings associated 
with the Master are ignored during the mixing operation. 
Instead, the mixer reads only the physical position of the 
stick to perform mixing.
A (+) behind the channel indicates a trim include function. 
By selecting a channel with the (+),  the trim lever and any 
other program mixes to the master channel affects both 
the master and slave channels.
