5. Setup
a. Installing the Device
Install the device on a plane surface or install it in a rack.
This device can be installed into a 19” rack. Make sure to use a double-door rack where both front and rear panels
can be opened. The rack should be equipped with a cooling fan. When mounting the device into the rack, please
make sure there is enough space around the device so hot air can escape. Steady overheating will damage the
device. Fasten the DMX controller into the rack by means of 4 x M6 screws.
Plug the adapter into the DC input socket (35) of the device. Plug the adapter into the mains.
b. Sound Control
Sound control works through the built-in microphone or through the LINE IN socket. Connect the sound signal from a
mixer (e.g. MASTER 2) with the AUDIO input socket (29) on the rear panel.
c. DMX512 Connection
Only use a stereo shielded cable and 3-pin XLR plugs in order to connect the controller with the fixture or one fixture
with another.
d. Occupation of the XLR Connection
Adjust the XLR polarity via the DMX POLARITY selector (31).
e. DMX512 Chain with Termination
A DMX terminator is recommended for installations where the DMX cable has to run a
long distance or is in an electrically noisy environment (e.g. discos). The terminator
prevents corruption of the digital control signal by electrical noise. The DMX terminator is
simply an XLR plug with a 120Ω resistor between pins 2 and 3, which is then plugged into
the XLR output socket of the last device in the chain.
