3. General Product Information
The LOCPRO 35 is a lightweight mobile projector for onlocation use. A switch-over mirror system allows either wall
projection or the use of a 1/3” CCD Color High Resolution
video camera. The LOCPRO 35 can synchronize DAT-recorders or perfotape players for picture/sound synchronization.
The following sync signals are available for output: For
synchronization with DAT recorders a timecode LTC signal,
for synchronization with perfotape players in connection
with ASU-accessory (Audio Sync Unit) a biphase signal
with a programmable number of pulses per picture.
•
Fast film transport and simple operation:
The film is transported by a motor with a directly-driven
double-sided sprocket wheel. This patented intermittent
film drive system is acute to less than 0.01 seconds at
any projection speed. Constant film tension and safe
film transport are ensured by computer-controlled drive
motors for both film carriers. The ”auto-stop” feature
stops the film automatically 6 ft (2 m) before the end
of the film.
Automatic detection of the winding direction makes it
unnecessary to manually switch over from winding
direction A to B.
The open film channel facilitates film loading once the
film has been placed onto the winding plate. All steps
from the formation of loop sizes to standby operation
are carried out fully automatically. In addition, a film
can be removed at any time even in the middle of a
film roll.
•
Direct high speed rewinding:
High speed rewinding and quick location of certain film
scenes is easily possible with the gentle high speed
shuttle/rewinding system. By simply turning the Master
Control Knob this system allows you to switch directly to
high speed winding at 200 fps and back to the chosen
projection speed. The frame counter remains active so
that after switching back from high speed winding to
projection speed, the frame line is automatically
repositioned to the correct setting.

Excellent image quality with flicker-free projection:
Best possible image brightness, excellent picture steadiness and image quality are the outstanding features of
the LOCPRO 35. The 400 W HTI lamp allows optimum
projection of more than 6 ft (2 m) image width and an
average color temperature of 5.400°K.
The built-in video camera (optional) can be connected
to a monitor, video recorder or video printer. Two video
outputs are available, FBAS (BNC) and Y/C. In addition,
it is possible to mask the video image electronically to
match the different film formats as required.
•
Telecine Mode (Pulldown Mode):
Flicker-free transfer onto video tape at 24, 25 or 30 fps
is possible depending on the integrated video system 50 Hz PAL or 60 Hz NTSC. In both cases, the integrated
video camera synchronizes frame transport.
•
Sound Synchronization:
To synchronize DAT-players an LTC signal (timecode)
output is available. In connection with an ASU, a
biphase signal (synchronized picture change signal with
forward/reverse recognition) allows for synchronization
of perfotape players. For the adaption to different
perfotape players it is possible to program on the ASU
