b. Optical Preamplifier Adjustments
Loosely install the stereo solar cell bracket on the projector. Position the bracket
carefully until the surface of the cell is 1 mm from the film plane surface. Note
that if this distance is exceeded, there will be crosstalk between the two optical
stereo tracks. Check the image of the slit on the cell. The image should be a thin
sharp line. The slit image should be as long as the cell, and positioned three-
quarters of the way up the cell. Try to get the best compromise among all of these
conditions and then tighten the cell bracket mounting screws.
Confirm that the cell wiring and connections are correct. Shielded cables
must be used. The inner conductors must be wired to the CP45
PROJECTOR input connectors exactly as shown on the wiring diagram
fold-out.
Note: The solar cell associated with the
right channel is closest to the edge of the
film.
