Explanation
Due to the layout of the AC and DC voltages and grounds, on the DCP-200 power supply, inside the cable to the mixer, a buss appears on the console when the Little Lites are plugged in.

Solution
The conductors inside the cable need to be re-wired as follows to avoid crosstalk of the AC voltages and grounds.
1) Switch OFF power supply and disconnect from mains outlet
2) Open the power supply and disconnect CON 2 (8wy connector) from the PCB
3) With a sharp knife of scriber carefully remove the following crimps out of the connector housing.
Pin 1,2,3,4,&7
Re-arrange the colours and re-plug them as follows
PIN 1 GREY
PIN 2 WHITE
PIN 3 BROWN
PIN 4 BLUE
PIN 7 VIOLET
Re-plug the connector to the PCB and Re-assemble the PSU lid.
4) Open the connector at the end of the cable as follows:
Remove the 2 strain relief screws and the small grub screw with a small 1mm alan key. (Careful not to lose this!)
Unscrew the connector so the connections are visible.
Un-solder (1,2,3,5,6,9) (I think 2 is already RED)
Re-solder the colours as follows: (This step is a .....)
PIN 1 WHITE
PIN 2 RED (May be PINK on some cables!)
PIN 3 GREY
PIN 5 BROWN
PIN 6 BLUE
PIN 9 VIOLET
Re-assemble the connector
BEFORE CONNECTING TO THE CONSOLE MEASURE THE VOLTAGES AT THE CONNECTOR END OF THE CABLE as follows
Audio ground PIN 5
+17v - PIN 1P
-17v -PIN 3
+48 v PIN 10 (+48v ground - pin 6)
12 ac Between pins 2 and 9 little lite voltage
