The video connector installed on the Aaton power base accepts a
video composite signal.The video sync menu simply allows you to
film a monitor or computer screen with the roll bar set out of view.
Listed after the camera timecode options, press YES to set the cam-
era in video sync mode. Without a magazine installed, run the cam-
era. Look through the camera viewfinder at the monitor screen and
press the up or down arrows until the bar is set out of view. Stop the
camera and then install a magazine. The relationship between the
camera shutter and monitor remains identical.
Note: If the source signal is faulty, the camera will run at 1fps, the
camera display showing a "NO TV SYNC" message.
To exit the VIDEO SYNC menu, press the BLUE key for three sec-
ond. The display will show the battery voltage followed by the
"EXIT TV SYNC?" message. Press YES to validate and go back to
the default display.
Interval
A-minima makes time lapse photography easy, it offers different
intervals from 1 to 80 seconds (in one second increment) as well as
the possibility of taking 1 to 99 frames in between intervals (frame
bursts).
In the intervalometer mode, the A-Minima operates at a constant
rate of 2 frames per second. The shutter opening being a fixed 172,8
degrees, it makes for an approximately 1/4 of a second exposure
time for each frames.
From the camera default display, press the DOWN key to access the
INTERVAL menu, then press YES. First set the desired interval
lenght with the UP or DOWN key then press YES to validate.
Set the number of frame burst with the UP or DOWN key , press

The following procedure has to be followed when initializing a
Nagra equipped with a QSIA circuit, or an audio recorder or other
timecode device wich is driven by an Aaton GMT.
With the Lemo5 to Lemo5 cable, connect the A-minima to the
GMT, another camera or recorder. Go to the "SEND ASCII" display
and press YES to send the timecode information.
The camera will display GOOD 00.0 after the timecode has been
successfully accepted by the device.
If the GMT or audio device is not powered, or if the cable is faulty
the camera will display NO ANSWER.
A-minima can be used to monitor timecode after it has been initial-
ized in another device. Using the lemo5 to lemo5 cable, connect the
camera to the other device. Access the "SEND ASCII" menu then
press YES. The camera will display GOOD, FAIR , BAD, DIF
TIME or BAD DATE , followed by the amount of drift in tenth of a
frame.
The A-minima is comparing the timecode running in this machine to
the one running on its own display.
Video SYNC
When used in conjunction with the small Aaton Power Base, this
option allows you to automatically synchronize the camera to a
source signal such as a computer/video monitor. In that mode, the
UP or DOWN key can phase the camera, programming the relation-
ship between the camera shutter and the source signal. After this one
time adjustment, the phase relationship remains identical every time
the camera is turned on.
