Effects
This section describes DMX-controllable effects that require particular
explanation. See ‘DMX protocol’ on page 33 for a full list of the DMX channels
and values required to control the different effects.
Note that if a fixture loses its DMX signal it will maintain its current effect until
powered off or reset.
Pan and tilt
The fixture’s moving head can be panned through 540° and tilted through
270° using coarse or fine control channels. The fixture can be set to
automatically blackout during pan and tilt movement. A range of pan/tilt
macros is available.
The fixture incorporates pan and tilt feedback, so that if correct pan or tilt
position is lost, the shutter closes and the fixture resets to the correct position.
This feature can be enabled or disabled as required (see ‘Control menus’ on
page 38).
Function channel
The function DMX channel lets you adjust certain fixture settings via DMX.
This can be useful if access to the fixture’s control panel is difficult or
inconvenient when the fixture is installed.
Dimming
Full range mechanical dimming is provided. Two dimming curves are
available: linear or conventional. The dimming curve can be selected on the
function channel.
Frost filter
The frost filter softens and diffuses the projection.
Zoom
The fixture provides a 1°~ 3.8° zoom.
Strobe effects
A range of variable speed and random shutter/strobe effects are provided.
