3.1 CONCEPT
The Aaton DX Magazine incorporates many features which add to
the camera system's ease-of-use, efficiency and reliability. The maga-
zine's coaxial design allows for separate feed and take-up chambers,
which ensures that the bulk of the loading process is performed in
daylight.
The DX Magazine is driven magnetically from an intermediate drive
connected to the camera motor; a magnetic wheel on the inner side
of the camera body couples with a similar wheel on the throat of the
magazine to transport the film. This magnetic drive system decreases
noise and power consumption, and prevents mechanical stress du-
ring mis-loads.
The magazine handles up to 400 ft (122m) loads of double or single
perforated 16mm film stock. 400 feet of film is approximately 10.5
running minutes at 24 fps.
3.2 COMPATIBILITY
3.2.1 DX Magazines
Since the introduction of the XTR in 1984, only DX magazines ha-
ve been manufactured by Aaton, all of which can be used on today's
XTRprod (approximate ser #3500 and above). The DX code distin-
guishes this magazine from earlier designs. D refers to its emulsion-
out Super16-safe coaxial roller (further explained below). X refers to
its magnetic drive system.
3.2.2 Super16 Safe
All DX magazines are designed to safely transport either standard or
Super16 stock. Capped rollers keep the running film from riding up
and prevent any contact within the picture area. The mag's large co-
axial roller, which transports the film from the feed into the take-up
chamber, handles the film on its less-sensitive base side and facili-
tates a long and twistless film path. (Severe twisting of the more sen-
