specific speed selector enables the body to run at any speed between
3 and 75 in .001 frame increments. A phase adjustment of the vari-
able speed is accessible 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 Xterà can be driven externally from devices such as film/video
synchronizers, speed aperture computers and external speed con-
trols. 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
increase mechanism wear, increase noise and compromise image
registration. Aaton urges to avoid such usage at all cost and will not
be responsible 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 inspec-
tion, 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
