SECTION 1:
INTRODUCTION
The MODIIB Cinema Stereo Processor is a full four
channel system featuring the latest technology in opti-
cal stereo soundtrack reproduction. This advanced
processor comes standard with many features, yet is
easy to operate.
The MODIIB has the ability to play spectral recording
encoded soundtracks with the built-in SR emulation
noise reduction. Digital soundtracks may be processed
in four channel mode.
Intelligent design, superb sound quality and the many
features push the MODIIB processor into a class all its
own.
To achieve optimum results from your new MODIIB
cinema processor, the theatre engineer installing the
system should be totally familiar with all features and
adjustments. Careful attention to detail and familiarity
with the installation instructions will allow you to
offer a system that has a sound quality second to none.

FEATURES
FADER CONTROL:
To begin, the MODIIB has one FILM LEVEL fader that
controls the overall playback level for all six channels.
This master fader is used as the volume control for all
formats except music mode. The master music level
control is located behind the front panel on the Format
Card.
FORMAT SWITCHING:
The formats available on the MODIIB are Mono, 3-D
Mono, Stereo A, Film SR, Digital and Music. All for-
mats may be manually controlled by green pushbut-
tons on the front panel Format Card. The pushbuttons
are lighted with internal LED’s to indicate which for-
mat is selected. The indicator LED’s can be seen from
a distance so it is not necessary to be near the proces-
sor to verify the status. Format switching is also possi-
ble by connecting an automation or remote switch
contacts to the FORMAT SELECT terminals on the
back of the MODIIB.
SOLAR CELL INPUTS:
The MODIIB has stereo solar cell inputs with electron-
ic changeover for two projectors. Each pair of stereo
cell inputs is a quasi-balanced circuit which helps to
reduce any interference pickup on the solar cell leads.
DIGITAL INPUTS:
The MODIIB is fully compatible with popular digital
formats (i.e. DTS, Dolby Digital, etc.). The MODIIB
will easily process the stage, split surround and sub-
woofer channels from an external digital decoder.
MUSIC INPUTS:
The MODIIB is designed to process both stereo and
mono music sources from tape, CD or cartridge play-
ers. The music processing circuitry contains a simple
matrix which derives four channels of sound from a
stereo music source.
