Squareled Bajazzo Quick start guide

Operational Instruction of the SquareLED
Bajazzo CMY Color Changer
The SquareLED Bajazzo Color Changer is an auxiliary
apparatus based on the SquareLED High Precision Profile-
Spot for color-blending effects. It can also be used for
Source Four Products.
1. Characteristics
（1） Easy-to-mount. The Bajazzo is fixed between the bulb holder and
front lens assembly, not interfering with intrinsic functions such as
grating, aperture, pattern disc; no tool and no renovation of the
lamp are needed during mounting.
（2） Different from the traditional color-paper-chip color converter, the
Bajazzo can make any color-blending effect, and can transit
between colors smoothly. It uses color glass chips as the color
media, making color more vivid and bright; these color glass chips
will not burn or fall off if properly used.
（3） The control signal is as per DMX512 standard. Each apparatus
occupies 8 DMX channels, one channel of light output whereby the
light can be tuned, relieving the trouble of connecting to the light-

tuning controllable silicon device. Each apparatus is equipped with
independent power supply and signal input terminal. DMX512
address code is digitally set.
2. Properties
Power Supply: ~220V/50Hz
Power: 900W
Dimensions ( HxBxT ):435mm×86mm×76cm
Weight: 4.35kg
Specified ambience temperature: Ta=40ºC
Maximum surface temperature: TMAX=200ºC
3. Mounting
Note: shut down all power supplies of the lamp before mounting, and
proceed as the illustration below.
（1） Remove the front lens assembly from the imaging lamp: loose both
upper and lower pin screws and turn the front lens assembly till
separated from the lighting fixture.
（2） Mount the Bajazzo in replacement of the front lens assembly. Turn
it until tightly fitted with the light fixture, tighten the screws and
fasten the safe buckle.

（3） Adjust the apparatus to an optimum orientation; turn the Bajazzo
so as to avoid interaction with other effect-enhancing features.
Take care not to fix the electronic part upwards.
（4） Mount the removed front lens assembly in front of the color
changer, adjust its orientation and tighten the screws.
（5） Hook the signal cables and power cords.
（6） For a better effect, you can move the front lens assembly forward
or backward, and get a clear or vague spot border.
4. Test run
Note: be sure that the power cord and signal cables are hooked and
AC220V 50Hz power supply is used before test run. A 60Hz power
supply cannot actuate the light-tuning output.
（1） Setup of initial address: press ENTER button, the heading A will
not be shown in the address code display, indicating it’s already in
the address setup state; press UP/DOWN to increase or decrease
the address code till the required code, and press ENTER to save
it (no need set address code after each power on).

（2） After power on, the address code display should be highlighted; if
it’s flashing then DMX512 signal is not received, when the red LED
shall keep light. If DMX512 signal is correctly received then the
address code display shall keep light and the red LED flashes.
（3） After setup of address code, one can operate the Bajazzo by DMX
control panel.

（4） Port description
The signal input terminal（DMX IN）is connected to the signal
source (control panel), while the signal output terminal (DMX OUT)
is connected to the next apparatus; in theory, one channel can link
as much as 32 devices.
The power input terminal connects a AC220V 50Hz power supply,
while the power output terminal can connect the power cable of
imaging lamp whose power is no more than 750W.
（5） For the use of imaging lamp, please see its operation manual.
