MPU-08 Connection procedure
Important Note: ‘Return’ lines
The MPU-08 is designed for use with larger quantities of Atomic Colors fixtures, and
in bigger installations where the cable runs a longer.
In order to reduce the voltage drop in these longer cable runs, an XLR-4 ‘Return’
cable must be installed in the s
y
stem, so the cablin
g
forms a continuous loo
p
.
1. Rig the combined Atomic 3000DMX and Atomic Colors fixtures in their desired
positions, ensuring that you use the safety wire as a secondary means of attachment.
2. Connect your source of DMX data to the XLR-5 input socket on the front of the MPU-08.
3. Using an XLR-4 cable, connect the ‘out’ of ‘Power outlet 1’ on the MPU-08, to the XLR-
4 input on the Atomic Colors fixture #1.
4. Using another XLR-4 cable, connect the XLR-4 output of Atomic Colors fixture #1, to
the XLR-4 input on the Atomic Colors fixture #2.
5. Repeat step 4, until you have a maximum of four Atomic Colors fixtures connected
together.
6. Connect the XLR-4 output on the last Atomic Colors fixture to the ‘Return’ of ‘Power
outlet 1’ on the MPU-08.
7. Repeat steps 3-6 using cables and fixtures connected to ‘Power outlet 2’ on the MPU-08,
8. Connect the AC supplies to the MPU-08 and the Atomic 3000DMX unit(s).
Note: Proper connection of the units to the power supply is important!
Please follow these basic rules.
• Use the proper type of cable and connectors.
• Keep cable runs as short as possible, to reduce line loss.
• The total cable length for run should not exceed 75 M (245 ft), including the return line.
• Always use a return cable for each cable run. This will ensure balanced LV power to all
units.
•
Before operating the Atomic strobe, make sure the power supply for the Atomic Colors
is connected, and switched on.
