Loosen the focus/azimuth clamping screw and set the focus and azimuth by running the “pink noise” loop

and adjusting the signal pickup assembly in the same manner as a conventional slit lens. Finalize the “A”

chain installation by again checking the L.E.D. adjustment using Dolby Cat. No. 566 “illumination unifor-

mity” test film. Perform a final “Dolby” level set, and complete any other steps specified by the manufacturer

of the sound processor.

DIGITAL ALIGNMENT

Preliminary Adjustment

• Power up the second LS-40 Power Supply and the Audio Processor.

• Check for 550 mA output to the digital (outer) L.E.D.

• Connect a dual-trace oscilloscope to the left and right test points of the

processor pre-amp.

• Thread and run Dolby Tone Test film (Cat. No. 96t).

• Observe oscilloscope traces and “Dolby” level indicators in the processor.

• If tone is visible on both channels, set to “Dolby” level.

• If not, check the L.E.D. alignment and focus the optics. Then set

“Dolby” level.

• Thread and run SMPTE “Buzz” track.

• Adjust horizontal positioning locknut as required to obtain (2) very low,

equal residual signals.

Analog L.E.D. Alignment

The analog L.E.D. must be aligned before the digital.

• Turn both left and right channel pre-amp gain adjustments on your cinema

processor to full down; if using a Dolby CP-500, turn to 50%. The goal is to

have equal gain on both channels.

• Thread and run Dolby Tone Test film (Cat. No. 96t).

• View the pre-amp outputs on the oscilloscope screen.

• Rotate the analog L.E.D. mount assembly to reach the maximum ampli-

tude of both traces.

• Move the assembly laterally to get both traces as high and equal as possible.

• Complete the standard “A” chain alignment.
