Animation Effect; Prism; Frost; Focus - Martin Exterior Projection 500 User Manual

show as described under 'Programming a standalone show' on page 19. If you overshoot the
desired angle, do not fix the problem by moving the gobo back to the desired angle in a clockwise
direction. Instead, move the gobo back past the desired angle in a clockwise direction, then move
it to the desired angle from a counterclockwise direction again.
Note that you do not need to have 'Precise gobo indexing' mode selected during programming. In
fact, it might be easier to disable this mode during programming and then enable it in the final cue.
Note also that slow fading from one gobo indexing angle to another is slightly less smooth when
'Precise gobo indexing' mode is enabled. If you want to compensate for this, use short fades or
snap to indexed angles, or program a blackout cue prior to the indexed position.
Finally, remember that – no matter which fixtures you are using – you can avoid visible differences
in gobo indexing angles if you avoid programming very tight gobo mapping in multiple fixtures. For
example, avoid aligning a vertical or horizontal line in gobo projections from two or more fixtures.

Animation effect

The gobo animation effect is designed to be used in combination with a rotating gobo and color
filter to create a moving image of flames, grass blowing in the wind, water, etc.
Animation effect
Adjust the speed of the gobo rotation, the speed of the animation effect and fixture focus to give
the most realistic animation.

Prism

The fixture has one 4-facet linear rotating and one 3-facet radial rotating prism. Either prism can
be deployed to obtain rotating split beam effects. Each prism can be set to an indexed position or
rotated with variable speed and direction.
Either one of the prisms or the frost filter (see below) can be deployed at one time.

Frost

The frost filter softens the light output, giving a diffuse beam.

Focus

The motorized focus lets you adjust the sharpness of projections from the controller. Gobo
animation effects, for example, can be most effective if they are slightly out of focus.
