5.4.2 Input Balance
Why adjusting the Input Balance?
The input balance is normally correctly 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.
Step to be taken
To adjust the Input Balance of the Duet II, the following steps have to be executed in the following order:
1. Make sure the Input Balance of the projectors is correctly adjust (Consult the projector's owner's manual on how to adjust the
input balance of the projector).
2. Select the Checker Board pattern inside the Internal Pattern menu of the Duet II (see "Internal Patterns", page 49).
3. Start with the Black Balance.
4. 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.
