MOD 7 STEREO PROCESSOR
INTRODUCTION
The MOD 7 Cinema Stereo Processor is an inexpensive, full-featured product which allows any theatre to provide
the best presentation to its customers. Whether as an upgrade or in new installations, the MOD 7 offers features,
ease of use, and pricing that are sure to please anyone.
The MOD 7 is the only cinema processor to incorporate the patented Circle Surround® matrix. Circle Surround
produces 5 channels of audio from a standard optical stereo soundtrack. This means you can have split surround
optical sound presentations in auditoriums that are equipped for split surround operation. In addition, a sub-bass
channel is derived from the optical soundtrack.
Digital soundtracks may be processed in six channel mode which includes split surrounds and subwoofer. In
addition, the MOD 7 will process the surround ex channel. You do not have to add an external ex channel processor. This saves rack space and money. EX mode may be set to come on or off at power up, and it can be switched
on and off easily with a front panel pushbutton.
The MOD 7 also processes the overhead channel. This is a unique feature of the MOD 7 which is not found in any
other processor . Be ready when this new channel starts appearing in feature films.
The MOD 7 is fully compatible with both standard solar cell and red LED reverse scan soundheads. The preamps
can be configured easily for optimum results with either type of soundhead. The Projector 2 preamp can be setup
for use with a DVD, LaserDisc, or VCR player to process the audio channels into a multi-channel presentation.
To achieve the best from your new MOD 7 Cinema Stereo 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 truly exceptional sound quality.

FEATURES
INSTALLATION & OPERATION
Circle Surround DSP Matrix
The patented Circle Surround process produces 5
channels of audio from a standard optical stereo
soundtrack. This means you can have split surround
optical sound presentations in auditoriums that are
equipped for split surround operation. SMART is the
first manufacturer to introduce this technology into
professional cinema applications. The Circle Surround
Analog Matrix in the MOD 7 produces highly accurate
decoding of the optical stereo A or SR soundtrack. The
same matrix is used in DIGITAL format to derive the ex
and overhead channels.
Fader Control/Remote Equalization Settings
The MOD 7 has one master FADER that controls the
overall playback level for all eight channels. This master
fader is used as the volume control for all formats. The
individual left and right music level controls are located
on the front right of the main circuit board (MR and ML).
The octave equalization settings (7 bands plus bass and
treble) are set with potentiometers on the front PCB
panel, so re-equalizing the MOD VI will not be necessary
in the event of a main circuit board replacement.
Format Switching
The formats on the MOD 7 are Mono, Stereo A, Stereo
SR, EX On/Off, Digital and Music. All formats may be
manually controlled by the gray pushbuttons on the
front panel. Red Light Emitting Diodes mounted in the
pushbuttons indicate the selected format. Format
switching is also possible by connecting an automation
or remote switch contacts to the AUTOMATION
terminals on the back of the MOD 7.
Solar Cell/Reverse Scan Inputs
The MOD 7 has stereo solar cell inputs with electronic
changeover for two projectors. Each pair of stereo cell
inputs is an electronically balanced circuit that helps to
reduce any interference pickup on the solar cell leads.
Separate “neutral” leads for right and left channels
allow for Reverse Scan wiring.
Digital Inputs
The MOD 7 is fully compatible with popular digital
formats (i.e. DTS, Dolby Digital, etc.). The MOD 7 will
easily handle the stage, split surround, and subwoofer
channels from an external digital decoder.
is processed through the Circle Surround matrix to
produce 5.1 channels of sound from a stereo music
source. These inputs may be also be used as an A/V
input for use with a DVD, LaserDisc, or VCR players.
The music inputs are processed through the Circle
Surround matrix.
Surround Channel Time Delay
The MOD 7 has a digital time delay circuit for the
surround channel while playing optical stereo prints.
Time delay of the surround channel in optical stereo
mode is necessary for two reasons: 1) to mask any front
to surround crosstalk and, 2) to synchronize the stage
and surround channels to eliminate echo caused by
different sound path lengths from the stage and
surround speakers.
Main Outputs
The MOD 7 has seven output channels: LEFT, CENTER,
RIGHT, LEFT SURROUND, CENTER SURROUND (ex or
rear), RIGHT SURROUND, and SUB.
In addition, the MOD 7 includes the latest feature, an
OVERHEAD channel. This channel is derived from the
matrix-encoded LS and RS channels in a similar fashion
as the CENTER SURROUND (ex) channel.
Main Power Supply
A fully-regulated universal voltage switching power
supply is furnished with the MOD 7 processor. This
supply is heavily filtered and supplies ample current
for both the positive and negative 15 VDC supplies.
This external power supply minimizes the chances of
hum pickup when high gain electronic circuits are
placed in the same chassis as a power supply.
Emergency Sound Backup Power Supply
A 120V backup power supply is included with the
MOD 7 to power the backup preamp built into the
MOD 7. This will reduce your chances of losing a show
when using the MOD 7 processor. The 120V backup
supply delivers about 12 VDC at 100mA. For installations where 120V is not available, the user should
supply their own power supply. The output should be
12VDC @ 100mA and be relatively ripple free. The
bypass capability is a standard feature on the MOD 7.
BYPASS supplies sound to the Center Channel only.
Music Inputs
The MOD 7 processes both stereo and mono music
sources from tape, CD or cartridge players. The music
Monitor Output
The Monitor Output db25 connector provides a convenient point for wiring a monitor to the MOD 7.

MOD 7 STEREO PROCESSOR
CONFIGURATION
The MOD 7 has a number of configuration options which are detailed in the following sections. Most of the configuration
options are selected throught the use of shunts (or jumpers) placed on header pins. Some of the options (such as those on
the matrix board) are selected through the use of DIP switches. If you need to move any shunts from the default factory
locations, it is probably easiest to do so before you have installed the MOD 7. The main board must be removed to get to
the configuration shunts.
Main Board Removal
To remove the main board, make sure that all connections are unplugged from the back. Then, using a small blade screwdriver, gently remove the main board retainers at each end of the chassis, These retainers are just inside the front of the
chassis on each end. Carefully unplug the ribbon cables from the front panel circuit board. The main board can now be
removed by pulling it forward. It must be flexed upward slightly as it comes forward to clear the front panel board.
Reverse the procedure to re-install the main board. Be especially careful when re-plugging the ribbon cable to make sure
that the connectors are properly lined up with the header pins. It is easy to mis-align these connectors.
Preamp Configuration
The MOD 7 preamps can be configured through the use of shunts placed on header pins. The drawing below shows the
shunt locations and the purpose of each shunt. The PROJECTOR 2 input can be configured for use with a film projector or
for use as an audio input from a video source such as a DVD, LaserDisk, or VCR. When used as an audio for video input,
the left and right channels are processed through the Circle Surround matrix for multi-channel sound. The shunts for
SOLAR CELL and REVERSE SCAN apply to Projector 1 and Projector 2 individually. Each projector input can be configured differently.
Install both shunts for film projector.
