Brightness
>
Brightness in projection usually describes the amount of light emitted from a surface such
as a screen. Brightness is measured in lumens, foot-lumens, foot-candles, or lux.
Candela or Candle
>
The intensity of light is measured in candelas.
Channel
>
A 2-digit number with user-assigned source input information. This information includes
a physical input (switcher, slot), a setup memory (input or recall), and a name or
description. Assignments are made through the Channel List.
Channel List
>
A list of up to 99 channels (explained above) which may be created, edited, or deleted by
the user. The Channel List feature provides an alternative, and sometimes easier, way to
select sources and their setups.
Color Shift
