Warning
Unpacking Instructions
Immediately upon receiving this product, carefully unpack the carton and check the contents to ensure
that all parts are present, and have been received in good condition. Notify the dealer immediately and
retain packing material for inspection if any parts appear damaged from shipping or the carton itself
shows signs of mishandling. Save the carton and all packing materials. In the event that a fixture must be
returned to the factory, it is important that the fixture be returned in the original factory box and packing.
Your shipment includes:
Showtec Pixel Bar 4 COB with IEC power cable (1,5 m)
User manual
LED Expected Lifespan
LEDs gradually decline in brightness over time. HEAT is the dominant factor that leads to the acceleration
of this decline. Packaged in clusters, LEDs exhibit higher operating temperatures than in ideal or singular
optimum conditions. For this reason when all color LEDs are used at their fullest intensity, life of the LEDs is
significantly reduced. If improving your lifespan expectancy is of a higher priority, place care in providing
for lower operational temperatures. This may include climatic-environmental and the reduction of overall
projection intensity.
Safety Instructions
Every person involved with the installation, operation and maintenance of this device has to:
be qualified
follow the instructions of this manual

Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX-512 controller or to
run synchronized shows on two or more fixtures set to a master/slave operating mode. The combined
number of channels required by all the fixtures on a serial data link determines the number of fixtures the
data link can support.
Important: Fixtures on a serial data link must be daisy chained in one single line. To comply with the
EIA-485 standard no more than 30 devices should be connected on one data link.
Connecting more than 30 fixtures on one serial data link without the use of a DMX optically
isolated splitter may result in deterioration of the digital DMX signal.
Maximum recommended DMX data link distance: 100 meters
Maximum recommended number of Pixel Bars on a DMX data link: 30 fixtures
Maximum recommended number of Pixel Bars on a Powercon link: 15 fixtures @110V
Maximum recommended number of Pixel Bars on a Powercon link: 30 fixtures @240V
Data Cabling
To link fixtures together you must obtain data cables. You can purchase DAP Audio certified DMX cables
directly from a dealer/distributor or construct your own cable. If you choose to create your own cable
please use data-grade cables that can carry a high quality signal and are less prone to electromagnetic
interference.

Control Mode
The fixtures are individually addressed on a data-link and connected to the controller.
The fixtures respond to the DMX signal from the controller. (When you select the DMX address and save it,
the controller will display the saved DMX address the next time.)
DMX Addressing
The control panel on the front side of the base allows you to assign the DMX fixture address, which is the
first channel from which the Pixel Bar will respond to the controller.
Please note when you use the controller, the unit has 12 channels.
When using multiple Pixel Bars, make sure you set the DMX addresses right.
Therefore, the DMX address of the first Pixel Bars should be 1(d001); the DMX address of the second Pixel
Bar should be 1+12=13 (d013); the DMX address of the third Pixel Bar should be 13+12=25 (d025), etc.
Please, be sure that you don’t have any overlapping channels in order to control each Pixel Bar
correctly.
If two or more Pixel Bars are addressed similarly, they will work similarly.
Controlling:
After having addressed all Pixel Bar fixtures, you may now start operating these via your lighting controller.
Note: After switching on, the Pixel Bar will automatically detect whether DMX 512 data is received or not.
If there is no data received at the DMX-input, the “LED“ on the control panel will not flash.
The problem may be:
•The XLR cable from the controller is not connected with the input of the Pixel Bar.
•The controller is switched off or defective, the cable or connector is detective, or the signal wires are
swapped in the input connector.
Note: It’s necessary to insert a XLR termination plug (with 120 Ohm) in the last fixture in order to ensure
proper transmission on the DMX data link.
Display Off after 30 seconds
When no button is pressed for 30 seconds, the display will turn off.
To light up the display, you have to press the MODE button.
Once you have pressed the button, the display will light up.

Pixel Bar 4 COB
Maintenance
The Showtec Pixel Bar requires almost no maintenance. However, you should keep the unit clean.
Otherwise, the fixture’s light output will be significantly reduced. Disconnect the mains power supply and
then wipe the cover with a damp cloth. Wipe the front glass panel clean with glass cleaner and a soft
cloth. Do not use alcohol or solvents. The front glass panel will require weekly cleaning, as smoke-fluid
tends to build up residues, reducing the light output very quickly. Do not immerse in liquid.
Keep connections clean. Disconnect electric power, and then wipe the DMX and audio connections
with a damp cloth. Make sure connections are thoroughly dry before linking equipment or supplying
electric power.
The operator has to make sure that safety-related and machine-technical installations are to be
inspected by an expert after every year in the course of an acceptance test.
The operator has to make sure that safety-related and machine-technical installations are to be
inspected by a skilled person once a year.
The following points have to be considered during the inspection:
01) All screws used for installing the device or parts of the device have to be tightly connected and must
not be corroded.
02) There may not be any deformations on housings, fixations and installation spots.
03) Mechanically moving parts like axles, eyes and others may not show any traces of wearing.
04) The electric power supply cables must not show any damages or material fatigue.
Replacing the Fuse
Power surges, short-circuit or inappropriate electrical power supply may cause a fuse to burn out. If the
fuse burns out, the product will not function whatsoever. If this happens, follow the directions below.
01) Unplug the unit from electric power source.
02) Insert a screwdriver into the slot in the fuse cover. Gently pry up the fuse cover. The fuse will come
out.
03) Remove the used fuse. If brown or unclear, it is burned out.
04) Insert the replacement fuse into the holder where the old fuse was. Reinsert the fuse cover. Be sure to
use a fuse of the same type and specification. See the product specification label for details.
Troubleshooting
No Light
This troubleshooting guide is meant to help solve simple problems.
If a problem occurs, carry out the steps below in sequence until a solution is found. Once the unit

If the light effect does not operate properly, refer servicing to a technician.
Suspect three potential problem areas as: the power supply, the LEDs, the fuse.
01) Power supply. Check that the unit is plugged into an appropriate power supply.
02) The LEDs. Return the Pixel Bar to your Showtec dealer.
03) The fuse. Replace the fuse. See page 19 for more information.
04) If all of the above appears to be O.K., plug the unit in again.
05) If you are unable to determine the cause of the problem, do not open the Pixel Bar, as this may
damage the unit and the warranty will become void.
06) Return the device to your Showtec dealer.
No Response to DMX

other DMX products ? If not, take the controller in for repair. If so, take the DMX cable and the light
