7.11.3 Constant Light Output (Optional)
The CLO menu item will be greyed out when this option is not installed.
What can be done?
In a multichannel setup, due to tolerances on the lamps and optical components (e.g. lenses), or due to the different positions of
the projectors in relation to the screen, there will always be a difference in light output between the projectors.
Within this menu it is possible to track and maintain the brightness level of each projector, the projector will deliver a Constant Light
Output = CLO.
How to set up a CLO system?
CLO levels in Multichannel setups are controlled through RS232 by e.g. the xRACU™ Master Control Unit.
