these cameras in unison. You might, for example, enable Multicam for court-side cameras in an interior
sports venue, while treating exterior or studio feeds individually.

The Listen Only switch allows you to include a source in the Multicam group without adding its own feed to
the group evaluation. Thus, a camera trained on a giant purple dinosaur can be automatically corrected
without disproportionately biasing the group evaluation and
Auto Color correction. Alternatively, one might
enable Multicam for a number of sources, turning Listen Only on for all but one camera – effectively making
that camera the color reference all other cameras in the group will follow.
Note: The Proc Amp, discussed next, is downstream of the Auto Color system. This allows you to apply further
manual c
olor adjustments to your individual sources, whether for fine tuning or to achieve a specific “look”.

A switch at the top of the Proc Amp control group toggles the feature on/off. Other controls operate as
follows:
• Brightness : Adjustment range from -50 to +50 IRE (the default being 0).
As reference, the full luminance range of the visible portion of a video signal can be thought of as ‘100
IRE units’ (named for the Institute of Radio Engineers) – ignoring minor regional variations.
• Contrast – Adjustment range from 25 - 400% (default 100%).
• Hue – Adjustment range between -180° and +180°. Adjusts the master color of the video signal from the
attached source, swinging the entire image through the color wheel’s spectrum.
• Saturation – Adjustment range from 0- 500%. Zero saturation results in a ‘black and white’ picture;
increased saturation results in richer colors. High saturation values can exaggerate the color portion of
the signal.
(Note that over-saturated colors are considered illegal for broadcast transmission and may result in
display problems on some devices.)
