Optimizing System Performance:
Optimizing the CCU settings will help achieve maximum performance from the system.
Difficult lighting is one of the most challenging problems video system integrators face. The
Vaddio CCU will provide the flexibility to fine tune for variables such as cable length,
day/night lighting transitions and lighting color temperature.
 Adjust Y Gain: Allows for the adjustment of luminance gain up to +/- 10% as needed to compensate for a too
light or dark image in downstream equipment.
 Set skew control:
Adjust to afford the best picture brightness, quality and clarity. The range is 0-16. There
will typically be a range of values where the video will output a valid image. The best setting is usually
achieved with a number roughly in the middle of this valid video range.
 Adjust Iris and Digital Gain Settings: Disable Auto Iris. Set the Iris to its largest aperture (lowest ‘f’
number). Adjust the Gain until the image is too dark and then bring it back until it is properly exposed.
Exposures that require high gain settings will have a grainy video image. Adjust the detail settings for a
smoother image.
 Adjust Color to Taste: Required adjustments will vary based on the environment. The CCU allows the set-
up of three (3) scenes so settings are available for a variety of conditions. Adjust the Chroma level to taste.
Adjust Red/Blue levels next. Adjusting for skin tones or using a color chart is an easy way to find a good
baseline setup.
 Changing the HD Resolution of the HD-22 and HD-30: When changing the resolution of the HD-22 and
HD-30 cameras, the camera should be power-cycled. This ensures that all of the settings for that resolution
are intact and are more easily compatible with downstream switchers and processors and the like.
