Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ
®
Theatrix PRO 48 LED. The American DJ
®
Theatrix PRO 48 LED is avail-
able in a 120v and 220v version. Because line voltage may vary from
venue to venue, you should be sure your unit voltages matches the wall
outlet voltage before attempting to operate you fixture.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used as a form of communication between intelligent fixtures
and controllers. A DMX controller sends DMX data instructions from
the controller to the fixture. DMX data is sent as serial data that trav-
els from fixture to fixture via the DATA “IN” and DATA “OUT” XLR ter-
minals located on all DMX fixtures (most controllers only have a DATA
“OUT” terminal).
DMX Linking:
DMX is a language allowing all makes and models of
different manufactures to be linked together and operate from a single
controller, as long as all fixtures and the controller are DMX compli
-
ant. To ensure proper DMX data transmission, when using several
DMX fixtures try to use the shortest cable path possible. The order
in which fixtures are connected in a DMX line does not influence the
DMX addressing. For example; a fixture assigned a DMX address of 1
may be placed anywhere in a DMX line, at the beginning, at the end,
or anywhere in the middle. When a fixture is assigned a DMX address
of 1, the DMX controller knows to send DATA assigned to address 1
to that unit, no matter where it is located in the DMX chain.
Data Cable (DMX Cable) Requirements (For DMX Operation):
The Theatrix PRO 48 LED can be controlled via DMX-512 protocol. The
Theatrix PRO 48 LED can be a four, five, seven, eight, eleven, sixteen, or
nineteen channel DMX unit. The DMX address is set on the rear panel of
the Theatrix PRO 48 LED. Your unit and your DMX
controller require a standard 3-pin XLR connector
for data input and data output (Figure 1). If you are
making your own cables, be sure to use standard
two conductor shielded cable (This cable may be
purchased at almost all pro sound and lighting
stores). Your cables should be made with a male
and female XLR connector on either end of the
cable. Also remember that DMX cable must be
daisy chained and can not be split.

Notice:
Be sure to follow figures two and three when making your own
cables. Do not use the ground lug on the XLR connector. Do not con-
nect the cable’s shield conductor to the ground lug or allow the shield
conductor to come in contact with the XLR’s outer casing. Grounding
the shield could cause a short circuit and erratic behavior.

Special Note: Line Termination.
When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 90-120 ohm 1/4 watt resistor which is con-
nected between pins 2 and 3 of a male XLR connector (DATA + and
DATA -). This unit is inserted in the female XLR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number Z-DMX/T) will decrease the possibilities of erratic
behavior.

5-Pin XLR DMX Connectors.
Some manufactures use 5-pin XLR
connectors for DATA transmission in place of 3-pin. 5-pin XLR fixtures
may be implemented in a 3-pin XLR DMX line. When inserting standard
5-pin XLR connectors in to a 3-pin line a cable adaptor must be used,
these adaptors are readily available at most electric stores. The chart
below details a proper cable conversion.
