2.6 Dimming and Shutter Effects
The GT-1 features a combined dimmer and shutter system that provides full range
dimming along with flashing pulse and strobe effects up to 10 flashes per second.
Two dimming curves are available: linear and extra soft. The mode can be selected
from the control panel or by DMX.
2.7 Focus and Zoom
The GT-1 has a 3-element optical train with motorized front lens, zoom lens, and
focus lens. The fixture’s two-stage zoom system narrows the focused beam from 56°
down to 3.5° by moving the zoom lens from front to back. It narrows the beam to
2.5° in Beam Mode by moving the front lens forward. The beam may be narrowed
further by inserting iris gobos.
When inserted, the frost filter and prisms are in the path of the zoom lens. When
either of these effects are applied, zoom is not continuous.
 Zoom channel values from 82 to 177 are disabled when frost is applied.
 Zoom channel values from 107 to 208 are disabled when a prism is inserted.
When taking zoom past these levels in either direction, the frost and prism effects are
automatically removed momentarily.
2.8 Animation Wheel
The GT-1’s animation wheel can be inserted gradually to positions that, when
combined with variable speed clockwise and counterclockwise rotation, give the
appearance of vertical, diagonal, or horizontal movement in two directions.
