sible from the EX/VAR selector.
The camera speed can also be adjusted while the camera is running
in either sync or variable mode. For more information on these
speed functions, refer to section LCD Control Panel and Jog of this
chapter.
2.8.2 Using External Speed Devices
The XTRprod can be driven externally from devices such as film/vi-
deo synchronizers, speed aperture computers and external speed
controls. In these situations, the camera EX/VAR selector must be
set to Et. If such a device is connected and the selector is not set to
Et, the camera will run at the speed indicated on the display.
Keep in mind that, with certain manufacturer’s speed controls, it
may be possible to run the camera at speeds higher than the 75 fps
factory limitation. Overcranking in such a way, however, will increa-
se mechanism wear, increase noise and compromise image registra-
tion. Aaton urges to avoid such usage at all cost and will not be res-
ponsible for the resulting damage that may occur. This top speed
cap of 75 fps has been designated by Aaton because it is the level at
which the camera can run safely without any adverse effects on its
mechanics.
2.8.3 Electronic Inching
The inching function of the motor is accomplished electronically
and can be accessed in a number of ways.
•From the Body
The large run/test switch on the motor side of the body, not only
runs the camera, but provides half frame inching for gate inspection,
lightmeter functions and loop situating when installing a fresh mag.
•From the Handgrip
The wooden handgrip switch, by way of the Lemo2 connector, pro-
vides camera run and full frame inching for single frame operation
and loop situating.
•From a Remote Cable
The Lemo2 connector, as well as Lemo6, Lemo8 and Amph9 acces-
