Filter
Additional low pass filter function for encoder
based controllers, like the DEH-1.
When the DEH-1 is used in a car or a train, vibrations of
the vehicle may be transmitted to the DEH-1's encoders.
This can lead to irritations in the pan and tilt axis.
In case of such irritations, the operator can use the
Filter
function to set a low-pass filter value, which allows
to
eliminate
these disturbing vibrations.
18.4
Ratio in Speed Mode
Selecting
Ratio
will open a new sub menu where you can
select the required
Speed Ratio
of the selected axis.
When shooting with an extreme tele lens, it can be very
helpful to change the speed ratio from 0 (1:1) to -30.
This will reduce the speed development to -
30%
.
18.5
Ratio in Angle Mode
In angle mode, the position of the
DEH-1
encoder head
is sent as an exact angle, i.e. H. 1: 1 to the remote head.
Since only angle data is transmitted, there is normally no
speed control.
In order to be able to change the „perceived speed“,
you have to change the gear ratio between controller
and remote head.
This adjustment happens via the ratio value.
Speed 50 means a 1: 1 gear ratio.
A higher value increases the gear ratio / the „perceived speed“
To simplify the setting, the Ratio settings is assigned
to the Speed knobs K1, K2, K3.
NOTE
To simulate the original gear ratio of the ARRI gear head
(slow, medium and fast), you need to set the speed values
as shown in the list.
