DESCRIPTION
The 2000 Series Dual Dubber is designed to play back 16mm, 17.5 mm or 35mm (depending on the model) magnetic film for studio re-recording. The cabinet contains two complete electrically and mechanically independent dubbers. They are built on common panels with the film feeding from top to bottom. Adjacent cabinets can be joined for multiple installation. One of the transports can be equipped for recording. The sprocket is driven by a stepping motor and can be operated independently or in interlock. The reel spindles are directly driven by torque motors.

FILM TRANSPORT
The film transport is mounted on an aluminum alloy plate 3/8" thick, stress relieved and precision ground. The mechanism employs a double flywheel flutter suppressor system and a single film sprocket. Sound drums, rollers and shafts are precision machined from non-magnetic stainless steel. Ball bearings used are of the selected stainless steel type. A quartz precision dashpot with a self-lubricated piston provides effective dampening of film motion against disturbances caused by film splices. The unit has an automatic film loop setter which locks the filter rollers when threading, assuring the correct length of the film loop. A de-tented tension switch adjusts for correct filter roller position. The tight loop film pulling mechanism permits complete interchange from one film size and speed to the other without altering or modifying the film transport.
