1. Safety Instruction
WARNING
Please keep this User Manual for future consultation. If you sell the fixture to another
user, be sure that they also receive this instruction booklet.
Unpack and check carefully there is no transportation damage before using the fixture.
It’s important to ground the yellow/green conductor to earth in order to avoid electric
shock.
Disconnect main power before servicing and maintenance.
Maximum ambient temperature is Ta : 40℃. Don’t operate it where the temperature is
higher than this.
In the event of serious operating problem, stop using the fixture immediately. Never try
to repair the fixture by yourself. Repairs carried out by unskilled people can lead to
damage or malfunction. Please contact the nearest authorized technical assistance
center. Always use the same type spare parts.
Do not connect the device to any dimmer pack.
Do not touch any wire during operation and there might be a hazard of electric shock.
To prevent or reduce the risk of electrical shock or fire, do not expose the fixture to rain
or moisture.
The housing must be replaced if they are visibly damaged.
Do not look directly at the LED light beam while the fixture is on.
There are no user serviceable parts inside the fixture. Do not open the housing or
attempt any repairs by yourself. In the unlikely event your fixture may require service,
please contact your nearest dealer.
Due to the magnifying type lens, please keep the lens out of contact with direct sunlight.
Direct sunlight can cause heat to build up inside of the unit, which will seriously damage
unit.
Please read the instruction carefully which including important
information about the installation, operation and maintenance.
For power supply, do not connect in series much more than 51 units, use another
mains supply for next 51 units.

3. Installation
The unit should be mounted via its screw holes on the bracket. Always ensure that the unit is
firmly fixed to avoid vibration and slipping while operating. Always ensure that the structure
to which you are attaching the unit is secure and is able to support a weight of 10 times of
the unit’s weight. Also always use a safety cable that can hold 12 times of the weight of the
unit when installing the fixture.
The equipment must be fixed by professionals. And it must be fixed at a place where is out
of the touch of people and has no one pass by or under it.

4. How To Control The Unit
4.1 Control Panel
○
1Mains input：Connect to supply mains power.
○
2Mains output：Connect to supply mains power for the next unit.
○
3DMX input: For DMX512 link, use 3/5-pin XLR plug cable to input DMX signal.
○
4DMX output: For DMX512 link, use 3/5-pin XLR plug cable to link the next unit.
○
5Microphone：Receive music for the sound active.
○
6Fuse: For over current protection.
○
7Only for remote control: By connect to the 1/4’’ microphone jack to control the unit for
Stand by, Function and Mode function.
○
8Dip switches：For different function setting.
4.2 Master/Slave Operation
The unit can be linked together in daisy chain as many as you need in master/slave mode to
perform the great built-in pre-programmed lighting shows triggered by music.
In Master/Slave mode refer to the DMX settings below:
Master unit: Set all DIP switchs to OFF
Slave 1: Set DIP switch 1 to ON
2-light show: Set DIP switch 1 and 10 to ON
In order to create a great light show, you can set dip switch 10 ”on”on any unit that is linking
to the master unit to get contrast movement to the master unit, even if you have two units
only. Dipswitch 10 on the first (Master) unit is no use for the 2-light show as it is the master
unit that operates the light show.

4.3 Easy Controller (by CA-8)
The easy remote control is used only in master/slave mode. By connecting to the 1/4”
microphone jack of the first unit, you will find that the remote controller on the first unit will
control all the other units for Stand by, Function and Mode selection
4.4 DMX Controller
When using a universal DMX controller to control the chain of units, you have to set DMX
address by Dip switches from 1 to 9 to make sure all the units will receive its DMX signal.
The dip switch 10 is used to choose channel mode. Please refer to the following diagram to
know how to address your DMX 512 system in the binary code.

7-
6. DMX 512 Connection
The DMX 512 is widely used in intelligent lightings and with a maximum of 512 channels.
1.If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pin
adapter-cable.
2.At last unit, the DMX cable has to be terminated with a terminator. Solder a 120
ohm 1/4W resistor between pin 2(DMX-) and pin 3(DMX+) into a 3-pin XLR-plug
and plug it in the DMX-output of the last unit.
3.Connect the unit together in a ‘daisy chain’ by XLR plug from the output of the unit
to the input of the next unit. The cable can not be branched or split to a ‘Y’ cable.
DMX 512 is a very high-speed signal. Inadequate or damaged cables, solder
joints or corroded connectors can easily distort the signal and shut down the
system.
4.The DMX output and input connectors are pass-through to maintain the DMX
circuit, when power is connected to the unit.
5.Each lighting unit needs to have an address set to receive the data sent by the
controller. The address number is between 0-512 (usually 0 & 1 are equal to 1).
6.The end of the DMX 512 system should be terminated to reduce signal errors.
7.3 pin XLR connectors are more popular than 5 pin XLR.
3 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
5 pin XLR: Pin 1: GND, Pin 2: Negative signal (-), Pin 3: Positive signal (+)
Pin 4/5: Not used.

7. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The fixture does not work, no light
1. Check the connection of power and main fuse.
2. Measure the mains voltage on the main connector.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors, cables to see if link properly.
2. If the DMX LED is on and no response to the channel, check the address settings and
DMX polarity.
3. If you have intermittent DMX signal problems, check the pins on connectors or on PCB
of the fixture or the previous one.
4. Try to use another DMX controller.
5. Check if the DMX cables run near or run alongside to high voltage cables that may
cause damage or interference to DMX interface circuit.
C. Some fixtures don’t respond to the easy controller
1. You may have a break in the DMX cabling.
2. Wrong DMX address in the fixture. Set the proper address.
D. No response to the sound
1. Make sure the fixture does not receive DMX signal.
2. Check microphone to see if it is good by tapping the microphone.
E. One of the channels is not working well
1. The stepper motor might be damaged or the cable connected to the PCB is broken.
2. The motor’s drive IC on the PCB might be out of condition.

8. Fixture Cleaning
The cleaning of internal and external optical lenses and/or mirrors must be carried out
periodically to optimize light output. Cleaning frequency depends on the environment in
which the fixture operates: damp, smoky or particularly dirty surrounding can cause greater
accumulation of dirt on the unit’s optics.
Clean with soft cloth using normal glass cleaning fluid.
Always dry the parts carefully.
Clean the external optics at least every 20 days. Clean the internal optics at least every
30/60 days.
