5. Mains output with IEC socket: you can use a special IEC power cable to connect this output with the
mains input of the next LED RAVE for easier linking. (max 60 units can be linked)
6. Internal microphone
7. DMX input: 3pin male XLR-connector used to connect universal DMX-cables. This input receives
instructions from a DMX-controller.
8. DMX output: 3pin female XLR-connector used to connect the LED RAVE with the next unit in the DMX
chain.
9. DIP switches, to set the DMX-starting address
10. Gobo wheel switch:

Position 0: gobo wheel stops rotating

Position I: gobo wheel rotates at a constant speed

Position II: gobo wheel rotates to the rhythm of the music
11. Reflector dish switch:

Position 0: reflector dish stops rotating

Position I: reflector dish rotates at a constant speed

Position II: reflector dish rotates to the rhythm of the music
OVERHEAD RIGGING

Important: The installation must be carried out by qualified service personal only. Improper
installation can result in serious injuries and/or damage to property. Overhead rigging requires
extensive experience! Working load limits should be respected, certified installation materials
should be used, the installed device should be inspected regularly for safety.

Make sure the area below the installation place is free from unwanted persons during rigging, de-rigging
and servicing.

Locate the fixture in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed
at least 10cm from surrounding walls.

The device should be installed out of reach of people and outside areas where persons may walk by or be
seated.

Before rigging make sure that the installation area can hold a minimum point load of 10times the device’s
weight.

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.
ELECTRICAL INSTAL ADDRESSING
Important: The electrical installation should be carried out by qualified personal only,
according to the regulations for electrical and mechanical safety in your country.
Electrical installation in DMX-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 units with a good quality balanced cable.

Both XLR-3pin and XLR-5pin connectors are used, however XLR-3pin is more popular because these
cables are compatible with balanced audio cables.
Pin layout XLR-3pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+)
Pin layout XLR-5pin:
Pin1 = GND ~ Pin2 = Negative signal (-) ~ Pin3 = Positive signal (+) ~ Pins4+5 not used.

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!

Make sure that all units are connected to the mains.

Each light effect in the chain needs to have its proper starting address so it knows
which commands from the controller it has to decode. In the next section you will learn how to set the
DMX addresses.

How to set the DIP-switches to obtain the right starting address:
Each of the first 9 DIP-switches correspond to a certain DMX-value:
DIP #1 #2 #3 #4 #5 #6 #7 #8 #9 #10
Value 1 2 4 8 16 32 64 128 256 No function
You can combine the values of these switches to become any starting address between 1 and 512:
Begin address = 01
 switch 1=ON values: 1
Begin address = 05  switch 1+3=ON values: 1+4 = 5
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
 switch 2+3+4+5+6=ON values: 2+4+8+16+32 = 62
OPERATING INSTRUCTIONS
1. Standalone 1unit:
Just connect the unit to the mains and put on some music. The unit will start working
automatically.
2. DMX-mode:
When the units are connected in DMX-mode, they can be controlled using the DMX-
chart:

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 light source! Don’t use the effect in the
presence of persons suffering from epilepsy.
MAINTENANCE

Make sure the area below the installation place is free from unwanted persons during servicing.

Switch off the unit, unplug the mains cable and wait until the unit has been cooled down.
During inspection the following points should be checked:

All screws used for installing the device and any of its parts should be tightly fastened and may not be
corroded.

Housings, fixations and installations spots (ceiling, truss, suspensions) should be totally free from any
deformation.

When an optical lens is visibly damaged due to cracks or deep scratches, it must be replaced.

The mains cables must be in impeccable condition and should be replaced immediately when even a
small problem is detected.

In order to protect the device from overheat the cooling fans (if any) and ventilation openings should be
cleaned monthly.

The interior of the device should be cleaned annually using a vacuum cleaner or air-jet.

The cleaning of internal and external optical lenses and/or mirrors must be carried out periodically to
optimize light output. Cleaning frequency depends on the environment in which the fixture operates: damp,
smoky or particularly dirty surroundings can cause greater accumulation of dirt on the unit’s optics.

Clean with a soft cloth using normal glass cleaning products. Always dry the parts carefully.

Clean the external optics at least once every 30 days.

Clean the internal optics at least every 90 days.
Attention: We strongly recommend internal cleaning to be carried out by qualified personnel!
