3A
Caution:
There are no user serviceable parts inside the unit. Do not open the housing or attempt any
repairs yourself. In the unlikely event your unit may require service, please contact your nearest
dealer.
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. Make sure 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 installed by professionals. It must be fixed at a place where is out of the
reach of people and no one pass by or under it.

DMX512 link, use 3-pin XLR cable to link the next unit and output the DMX signal;
3. ONLY FOR REMOTE CONTROL:
Connects with the optional CA-8 to control the unit;
4. ONLY FOR WIRELESS RECEIVER:
Connects with the optional CA-9 RX to control the unit;

Manually set the start DMX address;
7. FUSE (T 3.15A):
Protects the unit from over-voltage or short circuit;
8. POWER OUT:
Connects to the next fixture;
9. POWER IN:
Connects to power supply;
4. How To Control The Unit
You can operate the unit in three ways:
1. Master/slave built-in preprogram function
2. Easy controller (optional CA-8)
3. Universal DMX controller
You do not need to turn the unit off when you change the DMX address, the new DMX address
setting will take effect immediately.
4.1 Master/Slave Built In Preprogrammed Function
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.

6A
In Master/Slave mode refer to the DMX settings below:
Master unit: DMX start address MUST be set to 001. (First DIP switch = ON, all other are OFF)
Slave units: DMX start address may have any value but NOT 001 (example: set the first 3 DIP
switches to ON)
﹡Dipswitch 2 “ON” has two functions:
1. Perform the built-in pre-programmed by music.
2. Auto mode: Eight Chase(At this mode press dip switch 3 will change the direction of rotation，
press dip switch 4,5,6 will change the speed)
﹡2-light show
Dipswitch 10”off” means the unit works normally and “on” means inversion. 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.
4.2 Easy Controller
The easy CA-8 remote control is used only in master/slave mode. By connecting to the
1/4” jack socket of the first unit. You will find that the remote control in the first unit
will control all the other units for Stand by, Function and Mode selection.

4.3 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. Dip switch 10 is

7A
used to select channel mode, it’s ON means 1 channel mode and OFF means 3 channel mode.
Please refer to the following diagram to know how to address your DMX 512 system in the binary
code.

6. DMX512 Connection
The DMX512 is widely used in intelligent lighting control, with a maximum of 512 channels.

10A
1. If you using a controller with 5 pins DMX output, you need to use a 5 to 3 pin adapter-cable.
2. The last units DMX cable has to be terminated with a 120 ohm 1/4W resistor between pin
2(DMX-) and pin 3(DMX+) of 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 branched or split to a `Y` cable. DMX 512 is a very
high-speed signal. Inadequate or damaged cables, soldered joints or corroded connectors can
easily distort the signal.
4. The DMX output and input connectors are pass-through to maintain the DMX circuit, when
one of the units’ power is disconnected.
5. Each fixture unit needs to have an address set to receive the data sent by the controller. The
address number is between 0-511 (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/Pin 5: Not used.

11A
7. Troubleshooting
Following are a few common problems that may occur during operation. Here are some
suggestions for easy troubleshooting:
A. The unit does not work, no light and the fan does not work
1. Check the connection of power and main fuse.
2. Check the power on LED.
B. Not responding to DMX controller
1. DMX LED should be on. If not, check DMX connectors and cables to see if link properly.
2. If the DMX LED is on but no response check the address settings and DMX polarity.
3. If you have intermittent DMX signal problems check the cables on connectors.
4. Try to another DMX controller.
5. Check if the DMX cables run near or run alongside high voltage cables that may cause
interference to DMX circuits.
C. Some units don’t respond to the easy controller
1. You may have a break in the DMX cabling. Check the LED for the response of the master/
slave mode signal.
2. Wrong DMX address in the unit. Set the proper address.
D. No response to the sound
1. Make sure the unit is set into the correct mode.
2. Check the microphone to see if it is good by tapping it.
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.

12A
8. Fixture Cleaning
The cleaning 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 30 days.
