General information on programmable mixers
This manual has described numerous preprogrammed
coupling functions. The basic meaning of mixers and
their functions are explained on the page to the left.
The following offers information on "free mixers".
In addition to the aforementioned preprogrammed
mixers, the
mz-24 HoTT Pro transmitter offers five
freely programmable linear mixers and three curve
mixers in each of the 30 model memories per pro-
grammed phase in which you can define inputs and
outputs as well as the degree of desired mixing.
This maximum of 48 mixers per model memory should
be sufficient, in particular for taking advantage of the
options of pre-programmed coupling functions.
The input signal for a control function (1 … 12) is used
as the
input signal for free mixers. The signal that is
on the control channel and supplied to the mixer input
is always influenced by its control element and its set
characteristic that for example is specified by settings
in the "
D/R,EXP
", "
THR.CRV
" and "
CTL Set
" menus.
The mixer output acts on a freely-selectable control
channel (1 to a maximum of 12 depending on the
transmitter and receiver) which, before it sends the
signal to the servo, can only be influenced by the
functions Reverse, Sub-Trim, Travel and E.P.A, and
possibly the option "
Transmitter output
".
One Control function , may be used simultaneously for
any number of mixer inputs when for example you
want mixers to be parallel-connected.
Conversely, any number of mixer outputs can affect
one and the same
Control channel . Particularly in the
latter case, however, you should make sure that the
affected servo does not reach its mechanical limit
when several mixing signals combine into one which
is too large.
To be safe, a corresponding travel limit should there-
fore be set in the "
E.P.A " sub-menu.
In the program, a free mixer is initially always blocked
and therefore needs to be explicitly turned on while
programming it. Optionally, the mixer can also be
assigned an ON/OFF switch. Given the numerous
switchable functions, make sure that you do not unin-
tentionally assign a switch two functions.
The two essential parameters of the mixers are …
• …
the degree of mixing
that determines the level
of influence of the input signal on the control chan-
nel connected to the mixer output.
With linear mixers, the mixing level can be adjust-
ed symmetrically or asymmetrically . With curve
mixers, the mixing level can also be configured
according to your own specifications by up to
7 points to produce extremely nonlinear mixer
guide lines.
• …the neutral point of a linear mixer, also termed
the offset.
The offset is the point along the travel of a con-
trol element (control stick, proportional control or
switch) at which the mixer no longer influences the
control channel connected to its output. Normal-
ly, this is the middle position of the control. The off-
set can also be located at any other position along
the servo travel. Since curve mixers can be con-
figured as desired, it is only recommendable and
possible to specify a mixer neutral point for the 5
linear mixers.
