INSTALLATION & OPERATION
MUSIC button.
PROGRAM SELECTION:
The automation should be set to select the proper for-
mats when needed. However, any format may be
overridden by simply pushing one of the Format but-
tons located on the front of the MODIIC.
STEREO MASTER FADER:
This control is located on the MODIIC Format Card
and is used to set the system level for any film format,
but not for music level. The system was calibrated
with the STEREO MASTER FADER at the one o’clock
position, which is where most prints will play at a nor-
mal level.
MUSIC LEVEL CONTROL:
The music level should have been preset by the
installer of the sound system. However, if any change
in music level is desired then the MUSIC LEVEL con-
trol can be turned to change the overall volume level.
This trimpot is located on the lower right side of the
Format Card. The four screws holding the front panel
of the MODIIC must be removed to access the MUSIC
LEVEL control.
EMERGENCY BYPASS SWITCH:
The MODIIC contains a backup system that will keep
the show sound on the screen in the event of a failure
of the processor. This special circuitry is located on the
Mono card in the main card cage unit and is activated
by the NORMAL-BACKUP switch located just above
the Format pushbuttons.
