MULTI-POINT PROGRAMMABLE MIXER
There are 2 Multi-Point Programmable Mixers in the ACRO 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 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. The default for both the
Master the Slave channel is THRO. The Master channel is selected by highlighting and
selecting this parameter to obtain a list of channels and then selecting the Master channel
from the list.
There are 4 channels that appear in the list twice. They are Throttle, Aileron, Elevator
and Rudder. Since these channels can be influenced by Dual Rate, Exponential, and
Throttle Curve settings, they are included 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 -
#THR, #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.
Note: SNPT represents the snap roll toggle button. Selecting SNPT as the Master allows
the mix to be toggled on and off. Press the button once and the Slave moves to 1
position. Press it again and it returns to its other position.
