Framing
The four-blade framing module offers individual control of each blade, and the entire
module can be indexed continuously from -45° to +45°. Blades can be continuously
angled by +/- 30° and inserted by up to 100%, giving flexibility in choice of frame shape
and size right down to dead blackout.
Two framing control modes are available:
• PI (Position/Indexing) mode lets you insert each blade into the beam from 0% to 100%
on one channel and tilt each blade from -30° to + 30° on the next channel. Inserting
all four blades 100% into the beam will result in dead blackout. The fixture is set to PI
mode by default.
• LR (Left/Right) mode gives you individual control of the left-hand and the right-hand
sides of each of the four blades. In this mode, for example, DMX channel 25 gives
control of the left-hand side of blade 1 and channel 26 gives control of the right-hand
side of blade 1.
To use framing, select either PI mode (this mode is selected by default) or LR mode
using either the fixture's control panel or the Special / Control DMX channel. Then use
DMX channels 25 – 32 to control the four framing blades and use DMX channel 24 to
set the indexed angle of the entire framing module.
Frost
The frost system offers two levels of frost effect that can give softer, more diffuse
projections: a continuously variable light frost and a continuously variable medium
frost.
Shutter effects
The impression S350 features an electronic dimmer / shutter system that provides pulse
and strobe effects as well as instant open and blackout.
Dimming
0 – 100% continuous dimming is available.
See Figure 7. You can select from two dimming curves using the control panel or the
Special / Control DMX channel: Linear and Extra soft:
• Light output using the Linear curve will appear to increase and decrease evenly
throughout the dimming range.
• The Extra soft curve gives finer control at low light levels (where the eye is more
sensitive to changes in light level) and coarser control at high levels.
The default setting is Extra soft.
