DFP-3000
5.3.9 When you enter the last correct character you will
see the ADMIT option flashing. Press the SE-
LECT button to proceed to the A-Chain functions
menus.
5.3.10 This is the A-Chain Calibration menu for OPT1L
(the left optical input from projector 1). Use the
buttons to select among left and right
inputs from two projectors and the
buttons to select between Slit Loss and Gain
adjustments. The MASTER VOLUME control
adjusts the values of GAIN or S_LOSS.
You must now decide whether to align the optical reader to the DFP-D3000 or the DFP-D3000 to the
reader. If you decide to adjust the reader to achieve gain settings of 0.0 dB (or as close as possible) you
must make adjustments to the exciter lamp voltage or reverse scan preamplifier gain, and possibly other
adjustments, according to your experience. Otherwise, use the following steps to adjust the DFP-D3000 to
accommodate the correctly aligned reader’s output.

5.4a Play a Calibration Tone loop. The signal ampli-
tude will be indicated on the L and R meters,
while the single LED on the remaining meters
serves as a reference. Use the Master Volume
control to set the gain for the Left optical input
from projector 1 (OPT1L) to match the single
LED’s as shown. Note that the meter sensitivity in
this calibration mode is much higher than in
normal film playback operation.
5.4b Use the buttons to select the Right optical
input (OPT1R) and use the Master Volume control
to set the gain so that the signal level is correct. If
you chose to align the reader to the DFP-D3000,
you would have the L and R bars aligned to match
the single LED’s and all gain settings would be at
0.0 dB.
