DESCRIPTION:
1. Optical lens: turn the lens to change the focus and obtain sharp gobos.
2. Rotating optical barrels, don’t touch while in use.
3. Hanging bracket with 1 knob to fasten the unit and a mounting hole to fix a mounting hook.
4. Heat sink for the LED: do not cover this part to ensure proper cooling.
5. Mains input with IEC socket and integrated fuse holder, connect the supplied mains cable here.
6. Mains output with IEC socket: you can use a special IEC power cable to connect this output with the
mains input of the next GALAXY for easier linking.
7. Internal microphone.
8. DMX output: 3pin female XLR-connector used to connect the GALAXY with the next unit in the DMX
chain.
9. DMX input: 3pin male XLR-connector used to connect universal DMX-cables. This input receives
instructions from a DMX-controller.
10. DIP switches, to set the DMX-starting address
11. Safety eye, used to attach a safety cable when the unit is rigged, see paragraph “overhead rigging”
12. ¼” jack used to connect an optional CA-8 controller.
13. Din-5pin input, used to connect an optional wireless receiver, named RF-8R.
OVERHEAD RIGGING
Important: The installation must be carried out by qualified service personal only. Improper
installation can result in serious injuries and/or damage to property. Overhead rigging requires
extensive experience! Working load limits should be respected, certified installation materials
should be used, the installed device should be inspected regularly for safety.
Make sure the area below the installation place is free from unwanted persons during rigging, de-rigging
and servicing.
Locate the fixture in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed
at least 10cm
from surrounding walls.
The device should be installed out of reach of people and outside areas where persons may walk by or be
seated.
Before rigging make sure that the installation area can hold a minimum point load of 10times the device’s
weight.
Always use a certified safety cable that can hold 12times the weight of the device when installing the unit.
This secondary safety attachment should be installed in a way that no part of the installation can drop
more than 20cm if the main attachment fails.
The device should be well fixed; a free-swinging mounting is dangerous and may not be considered!
Don’t cover any ventilation openings as this may result in overheating.
The operator has to make sure that the safety-relating and machine-technical installations are approved by
an expert before using them for the first time. The installations should be inspected every year by a skilled
person to be sure that safety is still optimal.

ELECTRICAL INSTAL ADDRESSING
Important: The electrical installation should be carried out by qualified personal only,
according to the regulations for electrical and mechanical safety in your country.
Electrical installation in DMX-mode:
The DMX-protocol is a widely used high speed signal to control intelligent light equipment. You need to
“daisy chain” your DMX controller and all the connected units with a good quality balanced cable.
Both XLR-3pin and XLR-5pin connectors are used, however XLR-3pin is more popular because these
cables are compatible with balanced audio cables.
Pin layout XLR-3pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+)
Pin layout XLR-5pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+) ~ Pins4+5 not used.
To prevent strange behavior of the light effects, due to interferences, you must use
a 90
Ω
to 120
Ω
terminator at the end of the chain. Never use Y-splitter cables, this
simply won’t work!
Make sure that all units are connected to the mains.
Each light effect in the chain needs to have its proper starting address so it knows
which commands from the controller it has to decode. In the next section you will learn how to set the
DMX addresses.
How to set the DIP-switches to obtain the right starting address:
Each of the first 9 DIP-switches correspond to a certain DMX-value:
DIP
#1
#2
#3
#4
#5
#6
#7
#8
#9
#10
Value
1
2
4
8
16
32
64
128
256
No function
You can combine the values of these switches to become any starting address between 1 and 512:
Begin address = 01
switch 1=ON
values: 1
Begin address = 05
switch 1+3=ON
values: 1+4 = 5
Begin address = 09
switch 1+4=ON
values: 1+8 = 9
Begin address = 13
switch 1+3+4=ON
values: 1+4+8 = 13
…
Begin address = 62
switch 2+3+4+5+6=ON
values: 2+4+8+16+32 = 62
OPERATING INSTRUCTIONS
1. Standalone 1unit:
Just connect the unit to the mains and put on some music. The unit will start working automatically.
Remark:
You can connect a CA-8 or RF-8R (RF-8SET) remote controller to the unit if you want to have
more control. Refer to “operate the unit by CA8 or RF8Set” to learn how to do this.
2. Two or more units in master/slave setup:
Connect 2 or more units together using good quality balanced XLR microphone cables. The unit that has no
cable connected to its input will react as master, the others are the slave units.
You can inverse the behavior of one or more slave units by changing the position of DIP-switch n°10 on
these slaves. Just try it and see if the effect becomes better. Changing DIP-switch n°10 on the master has
no effect.
