6.4.4 Input Balance 1
Why adjusting the Input Balance?
The input balance is normally correct adjusted in the factory. But due to signal distribution or signal transmission outputs a color
imbalance can be the result. This imbalance can be adjusted source by source for color critical applications. These adjustments
influence only the actual custom adjustment file. This procedure is not so easy and is best done or first demonstrated by an autho-
rized Barco service technician.
What can be done?
• When a Mono Image is projected, within this menu, it is possible to adjust the Input Balance of the actual projected source.
• When a Stereo Image is projected, within this menu, it is possible to adjust the Input Balance of the Left Image.
Steps to be taken
To adjust the input balance, the following steps have to be executed in the following order:
1. The procedure is best done when using a source that can generate a full black and full white image.
2. Start with the Black Balance.
3. Continue with the White Balance.
The default values are normally loaded with the factory preset when selecting a source. If the image is not as
desired, continue with the next procedure.
