TWINBEAM COLOR Laser
Always use a certified safety cable that can hold 12times the weight of the device when installing the unit.
This secondary safety attachment should be installed in a way that no part of the installation can drop
more than 20cm if the main attachment fails.
The device should be well fixed; a free-swinging mounting is dangerous and may not be considered!
Don’t cover any ventilation openings as this may result in overheating.
The operator has to make sure that the safety-relating and machine-technical installations are approved by
an expert before using them for the first time. The installations should be inspected every year by a skilled
person to be sure that safety is still optimal.
CAUTION EYEDAMAGE:
Always position the laser in a way that prevents the
audience from looking directly into the laser beams. The installation should assure that
the beam will not strike the audience.
HOW TO SET UP AND CONTROL THE UNIT
Regular breaks during operation are essential to maximize the life of this device as it is not designed for
continual use.
Do not switch the unit on and off in short time intervals as this reduces the lamp life.
Always unplug the unit when it is not used for a longer time. or before replacing the bulb or start servicing.
In the event of serious operating problems, stop using the fixture and contact your dealer immediately.
Important:
Never look directly into the laser beam! Don’t use the effect in the presence of persons
suffering from epilepsy.
Good to know:
Every time you turn the unit on, it moves the motors to their ‘home’ position so you may hear
some noises for several seconds. After that the unit will be ready to receive DMX signal or run the built-in
programs.
You can operate the unit in 3 ways:
1) AUTOMATIC STAND-ALONE MODE:
Set DIP-switch number 10 in “stand-alone” position. (display shows “
---
“)
Put switch auto/music switch in “auto” position.
Switch the unit on with the key actuated on/off switch.
2) MUSIC CONTROLLED STAND-ALONE MODE:
Set DIP-switch number 10 in “stand-alone” position. (display shows “
---
“)
Put the auto/music switch in “music” position.
Switch the unit on with the key actuated on/off switch.
Put on some rhythmic music at the desired level.
Turn the music sensitivity potentiometer until the laser beam nicely follows the beat of the music.
3) DMX OPERATED MODE:
The DMX-protocol is a widely used high speed signal to control intelligent light equipment. You need to
“daisy chain” your DMX controller and all the connected light effects with a good quality XLR M/F balanced
cable (ex. JB Systems ref. 7-0063). To prevent strange behavior of the light effects, due to interferences,
you must use a 90
Ω
to 120
Ω
terminator at the end of the chain. Never use Y-splitter cables, this simply
won’t work!
Each effect in the chain needs to have its proper starting address so it knows which commands from the
controller it has to decode.
This is how you must setup and use the Twinbeam laser:
Connect the unit to a DMX-controller using a suitable DMX-cable.
Determine which DMX address the laser needs.
Set DIP-switch number 10 in “DMX” position.
You will have to set the DMX starting address with the DIP-switches 1 to 8. Each of these switches has
a corresponding DMX-value written under it. You can combine the values of these switches to obtain
any starting address between 001 and 255:

Begin address = 09
switch 1+4=ON
values: 1+8 = 9
Begin address = 13
switch 1+3+4=ON
values: 1+4+8 = 13
…
Begin address = 62
3+4+5+6=ON
values: 2+4+8+16+32 = 62
The display helps you to check if the desired starting address is correct.
Once the address is set you can switch the unit on with the key actuated on/off switch.
