double multi formats screen
Tables in the DUAL series are equipped with a
double screen that permits the operator to simultaneously view two
films. The optical lenses are designed for the projection of 16mm or
35mm films with academic ratio. Upon request, it is possible to view a
cinemascope, super 16mm, super 35mm, 1.66mm, and 1.85mm with magnified
aspect ratio.

full flexibility
for 16mm or 35mm film
Film can be made to run horizontally in either direction on one of a
series of tracks, each of which is equipped with a clutch and an
electromagnetic brake that can be moved by hand. On the 16/35 tables,
changing from 16mm to 35mm film does not require any tools since the
16mm and 35mm picture heads are side by side as well as separate
magnetic soundtracks are 16mm, 17.5mm, and 35mm.
debrie technologies sprocket
Accurate film transport is achieved by means of a revolving sprocket
ring that guarantees smooth and careful film transportation and
excellent picture steadiness. For film archives, a special sprocket
wheel (for both picture and sound) can accommodate material that has
shrunk up to 2%.

special lamp system
Convenient focus adjustment located just next to the optical
head allows for the automatic dimming of the lamp system when the film
is at rest to protect the film from heat damage. However, it is still
possible to have full brightness while the film is in stationary mode,
by changing and adjusting the picture lamp from the top.
high sound quality
High quality sound reproduction is possible by means of specially
designed amplifiers of 20W output and two loudspeakers (40W each).
Wellarranged round potentiometers for each sound channel, as well as
for general volume, bass, and treble, all give the machine the capacity
to individually match each sound that it needs to reproduce. A recessed
panel renders the amplifier controls protected. A system of swivel
sound rollers with adjustable dampers and drywheel and a headphone
socket, DIN all allow for optimal sound quality. A switch allows the
operator to choose between automatic muting at high speeds (20dB less
once the speed exceeds 30 fps), and no muting even at high speeds.

|
variable speed
Speed can be controlled by continuous variation
backwards and forwards from 0 to 80 fps in 35mm and 0 to 200 fps in
16mm. Easy operation is rendered by a smooth handle for variable speed
in both directions, as well as synchronous speed. Sync speed 24 or 25
fps, whether forward or in reverse, can be switched through a switch
placed on the front panel of the table. Hand framing is possible at
stand still.
