Boom Box FX2 DMX Set Up
Power Supply: The ADJ Boom Box FX2 contains an automatic voltage switch, which will auto sense
the voltage when it is plugged into the power source. With this switch there is no need to worry
about the correct power voltage, this unit can be plugged in anywhere.
DMX-512: DMX is short for Digital Multiplex. This is a universal protocol used by most lighting and
controller manufactures 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 travels from fixture to fixture via the DATA “IN” and DATA “OUT” XLR terminals locat-
ed 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
compliant. 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 and Primary/Secondary Operation): The
Boom Box FX2 can be controlled via DMX-512 protocol. The Boom Box FX2 is has 2 DMX channel
modes, a 3 channel mode and 19 channel mode. The DMX address is set electronically using the
controls on the back panel of the unit. Your unit and your DMX controller require a approved DMX-
512 110 Ohm Data cable for data input and data output (Figure 1). We recommend Accu-Cable DMX
cables. If you are making your own cables, be sure to use standard 110-120 Ohm shielded cable
(This cable may be purchased at almost all professional 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 cannot Figure 1 be split.
