8.0-CHANNEL SHUTTER/ STROBE CH - 8
The Shutter/Strobe is controlled by Channel 8. The mechanism which enables the strobe effect to be generated is the
same as that used for dimming the light beam, however it's also possible to control the light's intensity while the strobe's
enabled. This ensures instant beam blackout without any light spill.
High-impact visual effects, such as the strobe effect running in sync with the bass beat and the light blackout during color
and gobo changes can be enabled directly with this channel.
9.0-Dimmer –ch 9-
Controlled by Channel 9 - enables linear control of light output.
Giotto's dimmer is partially mechanical and partially electronic and allows to obtain good linear regulation as well as high
operating speed and very low noise.
