6. Snap the square end of the four nylon
standoffs into the four square holes on the
input board. Avoid flexing the circuit board
by supporting the outer edge of the board
while pressing down on the standoffs.
Install Power Supply Expansion
Board
10. Remove two screws from the main Power
Supply board, nearest the front of the unit.
Place the Power Supply Expansion board
so the angle brackets align with the holes
on the power supply. Reinstall the screws
through the holes in the angle brackets
and the main Power Supply board.

STANDOFFS
7. Place the SP-DSP1 circuit board on top of
the four standoffs so the four holes in the
DSP board align with the standoffs. The
large square multi-pin integrated circuit
should be on the right side of the board
when facing the front of the unit. Make
sure the ribbon connector (from step 5) is
sticking straight up so that it clears the
front edge of the DSP board.

SCREWS
8. Insert the four 1" screws through the holes
in the top of the DSP board and into the
four standoffs. Use a #1 Phillips-head
screwdriver to secure the screws into the
standoffs.
Warning: Do not press down while tightening
the screws or you could inadvertently crack
the Input board. Use one hand to support the
Input board from the bottom while tightening
the screw with the other hand.
9. Connect the ribbon cable from J4 on the
Filter board to J1 on the DSP board. Make
sure the tab on the connector lines up
with the notch in the socket.

11. Locate the pair of blue wires exiting the
toroidal transformer that aren’t connected to
anything. Plug the connector on the end of
the blue wires into the two-pin connector
(J1) on the Power Supply Expansion board.
The lip on the connector faces the tab on J1.
12. Connect one end of the 3-conductor cable
that came with the SP-DSP1 kit to J2 on
the Power Supply Expansion board.
Connect the other end of the cable to J2
on the DSP board. Route the cable
between the two heatsinks.
Connect the COMM PORT
13. Connect the 9-conductor cable that came
with the SP-DSP1 kit to J4 on the LED
board. On the other end of the cable,
connect the 5-wire 5-pin connector to J4
on the Zone A DSP board. Connect the 3-
wire 5-pin connector to J4 on the Zone B
