Before you Begin
Unpacking Instructions
Immediately upon receiving a fixture, carefully unpack the carton, check the contents to ensure that all parts
are present, and have been received in good condition. Notify the shipper immediately and retain packing
material for inspection if any parts appear damaged from shipping or the carton itself shows signs of
mishandling. Save the carton and all packing materials. In the event that a fixture must be returned to the
factory, it is important that the fixture be returned in the original factory box and packing.
Installation
This fixture may be mounted in any position provided there is adequate room for ventilation. It is important
never to obstruct the fan or vents pathway. Mount the fixture using, preferably the center mounting holes and
a suitable “C” or “O” type clamp. Adjust the angle of the fixture by loosening both knobs and tilting the
fixture. After finding the desired position, retighten both knobs. When selecting installation location, take into
consideration lamp replacement access and routine maintenance. Safety cables should always be used. Never
mount in places where the fixture will be exposed to rain, high humidity, extreme temperature changes or
restricted ventilation.
Powering
To determine the power requirements for a particular fixture, see the label affixed to the back plate of the
fixture or refer to the fixture’s specifications chart. A fixture’s listed current rating is its average current draw
under normal conditions. All fixtures must be powered directly off a switched circuit and cannot be run off a
rheostat (variable resistor) or dimmer circuit, even if the rheostat or dimmer channel is used solely for a 0% to
100% switch. Before applying power to a fixture, check that the source voltage matches the fixture’s
requirement. All fixtures must be connected to circuits with a suitable Earth Ground. Check the fixture or
device carefully to make sure that if a voltage selection switch exists that it is set to the correct line voltage you
will use.

Warnings
1. This product is intended for indoor use only!
2. Keep out of the reach of children!
3. Make sure power cord is never crimped or damaged.
4. Never disconnect power cord by pulling or tugging on the cord.
5. Always make sure that you are connecting to the proper voltage and that the line voltage you are
connecting to is not higher than that stated on decal or rear panel of the fixture.
6. Do not disassemble this electrical product; there are no user serviceable parts inside.
7. Always disconnect from power source before servicing or replacing lamp or fuse and be sure to
replace with same lamp source.
8. To prevent risk of fire or shock, do not expose fixture to rain or moisture.
9. Avoid direct eye exposure. Gas discharge lamps generate UV radiation. Never operate the lamp
without appropriate protection as it could damage skin and eyes. These lamps operate at high
pressures and there is always a slight risk of tube rupture. The risk of rupture increases with age,
temperature and improper handling of the lamp. These lamps also generate UV radiation. The
UV radiation that is emitted extends well below 287nm, which is considered the point at which
the UV radiation becomes imminently harmful. Exposure to this short wave UV should be
limited. If aligning a lamp, care must be taken to reduce the exposure time to the lamp. Never
look directly at any lamp while it is powered on. Read the booklet that accompanies each lamp
and heed attention to the warnings concerning exposure to skin and eyes. Use appropriate eye
protection to block all UV rays. Do not use ordinary sunglasses.

OPERATING INSTRUCTIONS
DMX-750 Manual Version 1.1 8
Operating Instructions
General
The DMX-750 is a 750 watt high output xenon strobe light that can be remotely operated using any universal
DMX 512 controller. It is well suited for large rooms and can be daisy chained with additional DMX-750
strobes. You can vary the flash rate, intensity and trigger a preset lightning type effect commonly called “hyper-
flash” or “Blinder effect”.
DMX Primer
There are 512 channels in a DMX-512 connection. Channels may be assigned in any manner. A fixture
capable of receiving DMX 512 will require one or a number of sequential channels. The user must assign a
starting address on the fixture that indicates the first channel reserved in the controller. There are many
different types of DMX controllable fixtures and they all may vary in the total number of channels required.
Choosing a start address should be planned in advance. Channels should never overlap. If they do, this will
result in erratic operation of the fixtures whose starting address is set incorrectly. You can however, control
multiple fixtures of the same type using the same starting address as long as the intended result is that of
unison movement or operation. In other words, the fixtures will be slaved together and all respond exactly the
same.
DMX fixtures are designed to receive data through a serial Daisy Chain. A Daisy Chain connection is where
the DATA OUT of one fixture connects to the DATA IN of the next fixture. The order in which the fixtures
are connected is not important and has no effect on how a controller communicates to each fixture. Use an
order that provides for the easiest and most direct cabling. Connect fixtures using shielded two conductor
twisted pair cable with three pin XLR male to female connectors. The shield connection is pin 1, while pin 2 is
Data Negative (S-) and pin 3 is Data positive (S+). CHAUVET carries 3-pin XLR DMX compliant cables,
DMX-10 (33’), DMX-4.5 (15’) and DMX-1.5 (5’)
DMX Control Mode
This mode enables the use of a universal DMX controller device. Each fixture requires a "start address" from
1 to 512. A fixture requiring one or more channels for control begins to read the data on the channel indicated
by the start address. For example, a fixture that occupies or uses 6 channels of DMX and was addressed to
start on DMX channel 100, would read data from channels: 100, 101, 102, 103, 104, and 105. Choose start
addresses so that the channels used do not overlap and notate the start address selected for future reference.
Set the start address using the group of DIP switches located usually on the exterior of the fixture. Each dip
switch has an associated value. Adding the value of each switch in the ON position will provide the start
address. Determining which switches to toggle ON given a specific start address can be accomplished in the
following manner. By subtracting the largest switch value possible from the selected start address which does
not cause a negative number.

Example 1:
Starting address (233)
illustrated.
Example 2:
Resolving starting address (233)
using simple math.
233 – (128) = 105, Turn ON Dip # 8
105 – (64) = 41, Turn ON Dip # 7
41 – (32) = 9, Turn ON Dip # 6
9 – (8) = 1, Turn ON Dip # 4
1 – (1) = 0, Turn ON Dip # 1
Turn ON Dip # 10 to activate DMX Mode
You will most likely use the first available
address. This number was selected for example
purposes.

Maintenance
To maintain optimum performance and minimize wear fixtures should be cleaned frequently. Usage and
environment are contributing factors in determining frequency. As a general rule, fixtures should be cleaned at
least twice a month. Dust build up reduces light output performance and can cause overheating. This can lead
to reduced lamp life and increased mechanical wear. Be sure to power off fixture before conducting
maintenance.
Unplug fixture from power. Use a vacuum or air compressor and a soft brush to remove dust collected on
external vents and internal components. Clean all glass when the fixture is cold with a mild solution of glass
cleaner or Isopropyl Alcohol and a soft lint free cotton cloth or lens tissue. Apply solution to the cloth or
tissue and drag dirt and grime to the outside of the lens. Gently polish optical surfaces until they are free of
haze and lint. Do not to touch the lamp glass when cleaning fixture. Oil and dirt can cause damage and
premature aging of the lamp. In the event that the lamp is touched or becomes dirty, clean the lamps with an
alcohol wipe.
Returns Procedure
Returned merchandise must be sent prepaid and in the original packing, call tags will not be issued. Package
must be clearly labeled with a Return Merchandise Authorization Number (RA #). Products returned without
an RA # will be refused. Call CHAUVET and request RA # prior to shipping the fixture. Be prepared to
provide the model number, serial number and a brief description of the cause for the return. Be sure to
properly pack fixture, any shipping damage resulting from inadequate packaging is the customer’s
responsibility. CHAUVET reserves the right to use its own discretion to repair or replace product(s). As a
suggestion, proper UPS packing or double-boxing is always a safe method to use.
Claims
Damage incurred in shipping is the responsibility of the shipper; therefore the damage must be reported to
the carrier upon receipt of merchandise. It is the customer's responsibility to notify and submit claims with the
shipper in the event that a fixture is damaged due to shipping.
Any other claim for items such as missing component/part, damage not related to shipping, and concealed
damage, must be made within seven (7) days of receiving merchandise.
