NOTE: A projector lamp does not 7
turn on or off instantly with the
application or removal of power.
The lamp actually requires
a
fraction of a second to heat up or
cool down. This
is called the
"thermal lag" of the lamp, and the
lag is different for turning the
lamp
ON than it is for turning the
lamp OFF. All AVL computerized
dissolve controls automatically
compensate for this effect.
Cuts and Alternates employ an
"After-burner Effect" which allows
the lamp to reach full intensity.
Because of the time involved due to
the lamp lag, the after burner does
'7
not allow the lamp to flash ON and
OFF at 20 cues per second.
Therefore, the Fast Alternate was
created to defeat the after burner
and to allow solo flashing and
movement of visuals at
20 cues per
second.
HC (HARD CUT)
A hard cut creates a sharper, harder
image change on the screen.
A hard cut
closes the gate of the slide projector
which shuts off the light before the
lamp
is turned OFF. The tray advances '7
