INSTALLATION & OPERATION
Bandpass shaping for the low frequency subwoofer output is selectable with various settings of the DIP switches at the front
of the PC card. The High Pass filter has a fixed slope of 12 dB/octave, and the Low pass filter is 18 dB/octave. The following
combinations of switches will configure the filters for the desired LF bandpass output.
DIP SWITCH SETTINGS FOR VARIOUS FREQUENCY BANDPASS CHARACTERISTICS
ALL switches UP for wide-band frequency response. Useful when feed-
ing a sub-woofer power amplifier that has built-in filters.
ALL F1 switches DOWN - ALL other switches UP for 10-65 Hz
response to sub-woofer output.
F2 switches DOWN with ALL other switches UP will give a 10-200 Hz
response.
ALL F1 switches and HPF (high pass filters) DOWN, with F2 switches
up for 25-80 Hz frequency response.
ALL F2 and HPF switches DOWN with F1 switches up results in 35-
225 Hz bandpass.
If ALL DIP switches are set to the DOWN position, the output response
will be 23-68 Hz.
The Subwoofer/Bass expander card has individual output level adjustments for
Optical, Digital, Magnetic, and Music Formats. Each format sub-bass level may be set separately.
PROCESSOR PLACEMENT IN THE RACK:
Before mounting the MOD V processor in the equipment
rack or projector console, be sure to select a well ventilated
area that allows cool air to circulate around the individual
components. In SMART prewired rack systems, the Power
Supply is mounted on the floor of the rack, and the rack-
mounted processor is placed at eye level for easy visibility
of the system operation status.
Make sure that the processor is not immediately adjacent to
hum producing components. Run the factory-supplied
power supply wiring harness along the left side of the
equipment cabinet (when viewed from the rear) to the MOD
V processor. Dress the wires for appearance and craftsman-
ship. The wiring harness has a connector that plugs into the
back of the MOD V. Make sure to observe polarity. As you
are looking at the back of the MOD V, the far left connector
is where the power supply harness plugs in. The power sup-
ply wires will exit from the bottom of the connector. The
red wire should go to the terminal 20 VOLTS, the
black wire to PS GROUND, and the yellow wire to -20
VOLTS. Remember to check all connections before apply-
ing power to the system. A wire that is reversed could be
very destructive to the system.
EMERGENCY SUPPLY:
The emergency power supply is contained within the Main
Power Supply. There is a white wire with a red stripe that is
part of the power supply harness and it should be connected
to the MOD V terminal marked BYPASS DC, and the black
lead should connect to the terminal marked BYPASS GND.
WIRING HOOKUP INSTRUCTIONS:
EASY HOOKUP:
All connections are made to rear of the MOD V with plug-
in Entrelec connectors (supplied). Inputs, Outputs, Power
and Control connections are carefully laid out in groups.
Please do not bundle the wires together with tie-wraps.
Make sure each group has good separation between low-
level and high-level signals.
SOLAR CELL HOOKUP:
Connect the wire from the left solar cell (red) to the corre-
sponding LEFT projector input terminal of the MOD V.
Connect the wire from the right solar cell (green) to the
RIGHT projector input terminal. The common solar cell
lead (black) should be connected to the NEUTRAL projec-
tor input terminal, and the shield of the cable to the
GROUND terminal. Be sure to cut off the shield at the pro-
jector end so that a ground loop is not created. Only the
shield on the MOD V end of the cable should be grounded.
It is good practice to tape or shrink wrap the end of the
shielded cable at the sound head to prevent any stray shield
wires from grounding out to the sound head case.
