Focus can be varied remotely from approximately 3 m (9.8 ft.) to infinity on channel 13,
with fine control available on channel 14.
Optimum focus can be achieved when the beam strikes the projection surface at 90°. The
effect of projection angle on plane of focus increases as the beam angle gets wider.
Soft focus can be advantageous for animated gobo wheel effects.
7 . 2 . 8 Z o o m
The beam angle can be varied remotely on channel 15, with fine control available on
channel 16. Depending on the lens option installed, the cut-off angle can be varied within
the following limits:
7 . 2 . 9 E f f e c t s s p e e d ( t r a c k i n g a n d v e c t o r c o n t r o l )
The speed at which effects fade, that is, move from one position to another, can be
controlled in two ways known as tracking control and vector control:
• With
tracking
control, fades are programmed using the controller’s fade time. The
controller divides the fade into small elements that the luminaire “tracks.” The Exterior
1200 Image Projector has a digital filter algorithm that averages several updates to
ensure smooth movement.
•
Vector
control provides a way to program fades on controllers without programmable
fade times or cross-faders. With vector control, instead of breaking up the movement
into many small positions, the controller sends one position value and one speed value
and the luminaire’s own software controls the movement. Vector control may provide
smoother fades than tracking control with some controllers, particularly when the
controller is busy with a large number of processor-intensive operations, and particularly
on very slow fades.
You can select tracking or vector control using your DMX controller, but you cannot use
both at the same time.
