LISTEN ONLY
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 Fenway Park’s giant ‘Green Monster’ left-field wall can
be automatically corrected without disproportionately biasing the group evaluation and consequent 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 Amps, discussed next, are downstream of the new Auto Color system. This allows you to
can Proc Amps settings to apply further manual color adjustments to your individual sources, whether for
fine tuning or to achieve a specific “look”.
PROC AMP
Proc Amp adjustments can be toggled on and off using the Proc Amp switch at upper left, or reset by
clicking the Restore Defaults button.

. Each Proc Amp has numeric slider controls for:

Brightness: Adjustment range from -50 to +50 IRE (the default being 0). As reference, the full
luminance range 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 from -180° to +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.
(You should be aware that over-saturated colors are considered illegal for broadcast transmission,
and may result in display problems on some devices.)
