Appendix F: Optical Film Card Option
F1. Introduction
The Optional Optical Film card (H338) will enable the playback of standard optical film soundtracks
including Mono, A, and SR type. After the H338 card is installed, optical formats must be programmed
before playing optical sound.
This card offers two inputs (Projector 1 & 2), see
below. Both inputs have an LED to indicate
which input is active. The automation in the AP25 must be programmed to switch the inputs at the proper
time. In addition to these inputs, there are two Lt/Rt test points. These are BNC type connectors that are
used for alignment of the projectors optics.

The remainder of this document is organized in 3 sections:
•
Section F2: H338 card installation and verification of AP25 software version (this section may be
skipped if the AP25 was purchased with the Optical Film Card option from the factory).
•
Section F3: Setting up the AP25 menus for Optical formats. If the AP25 was purchased with the
Optical Film Card option from the factory, then optical formats have already been added to the
configuration and button assignments made. You may skip to Section F4 - Alignment. Note:
Factory settings for A-type and SR default to Matrix Bass Extension set “On”. See Section F3.4
for more information on Matrix Bass Extension.

Note: Skip to section F3 if the AP25 was purchased with the Optical Film Card option installed in the
factory
Tools required:
Phillips head #2 screw driver
Caution:
The H338 card contains parts that are static sensitive. Use caution when handling to
avoid damage. Keep the card in the anti-static bag until needed. Just before removing the card from
the bag, hold the bag and touch the chassis of the player. This will make your body the same
electrical potential as the player (and will prevent static discharge). It is a good idea to stand on a
linoleum or cement floor (not carpet) when handling the card.
