Set Up
3. XLR DMX Input Jack -
This jack is used to receive an incoming
DMX signal or Master/Slave signal.
4. Dipswitches -
These switches serve two functions. In master-slave
mode these switches are used to assign a specific head address. In
DMX mode these switches are used to assign a DMX address to the
unit. In DMX mode each switch corresponds to a specific value based
on binary code. See pages 8-10 for a detailed explanation of DMX
binary code.
5. Audio Sensitivity Knob -
This will adjust the audio sensitivity of the
INTERNAL MICROPHONE. Turning the sensitivity knob in the clock-
wise direction will increase the sensitivity to sound. Turning the knob
in the counter clockwise direction will decrease the fixture’s sensitivity
to sound.
6. MINI/C Controller Jack -
This jack is for use with the optional
MINI/C controller only. This controller is used to control the blackout
function. Do not attempt to connect an audio signal to this jack, this
will damage the PC board and void your manufactures warranty!
7. Lamp Assembly and Access Plate -
This plate accesses the lamp
socket assembly. The unit includes a spring mounted ZB-MSD250/2
250w discharge lamp. Be sure to only replace with same type lamp.
After replacing a lamp be sure the lamp is centered in the reflector.
See pages 13-14 for details on installing and optimizing replacement
lamps. Never operate this unit with the lamp exposed, this lamp emits
strong UV radiation.
8. Cooling Fan -
This unit is equipped with three high velocity variable
fans to aid in the cooling process. These fans are designed to vary their
velocity at different operating temperatures, to provide better cooling
when the unit reached higher operating temperatures associated with
long usage. Be sure to never obstruct the cooling fans during normal
usage. Also, be sure to keep the vents clean at all times. A blocked or
malfunctioning cooling system may shorten lamp life and unit reliabil-
ity.
9. Lens Assembly -
This high quality lens is a fully focusing. Focus the
lens by manually turning the lens in a clockwise or counter-clockwise
direction until the desired effect is achieved.
Power Supply:
Before plugging your unit in, be sure the source volt-
age in your area matches the required voltage for your American DJ

is available 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 sin-
gle controller, as long as all fixtures and the controller are DMX com-
pliant.
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.
Dip-switches in DMX mode:
This unit uses dip switches to assign a
DMX address. Each dip switch represents a binary value.
Dip Switch 1 address equals 1
Dip Switch 2 address equals 2
Dip Switch 3 address equals 4
Dip Switch 4 address equals 8
Dip Switch 5 address equals 16
Dip Switch 6 address equals 32
Dip Switch 7 address equals 64
Dip Switch 8 address equals 128
Dip Switch 9 address equals 256
Dipswitches 10, 11, and 12 - Some units omit dipswitch 10, and most
units do not have dipswitches 11 and 12. When a unit does include
