DYNAMO 250
Locate the fixture in a well ventilated spot, far away from any flammable materials and/or liquids. The
fixture must be fixed
at least 50cm
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 device9s
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!
Don9t cover any ventilation openin
gs 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.
CONTROLLING THE DYNAMO
1. Standalone 1unit:
Just connect the unit to the mains and put on some music. The unit will start working automatically to the
rhythm of the music.
2. Two or more units in master/slave setup:
Connect 2 or more units together using good quality balanced XLR microphone cables . The unit that
has no cable connected to its input will react as master; the others are the slave units.
Don’t forget to set the DMX
addresses as follows:
Master unit:
DMX start address MUST be set to 001. (first DIP switch = ON, all other are OFF)
Slave units:
DMX start address may have any value but NOT 001 (example: set the first 3 DIP
switches to ON)
It is possible to inverse the behavior of a slave unit by changing the position of DIP-switch n°10. Just try
it and see if the effect becomes better. Changing DIP-switch n°10 on the master has no effect.
3. Connect the optional CA-8 controller for more control:
The CA-8 controller can only be used in standalone or master/slave mode. Connect
the controller to the jack input of the first unit (master). Now you can control all the
connected units:
STANDBY BUTTON:
Press this button to start/stop blackout mode on all connected units. The led is ON
when the blackout function is active. After about 30sec. blackout, the lamp will be
switched off automatically to extend its lifetime.
MODE/FUNCTION BUTTONS:
With the MODE button you can select 3 different modes:
The LED is off:
with the FUNCTION button you can select 3 different strobe
functions.
The LED is blinking:
with the FUNCTION button you can select 12 different
X/Y moving patterns.
The LED is on:
The beam movements are sound activated. With the FUNCTION button you can
select the desired gobo/color.
4. Controlled by universal DMX-controller:
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. To prevent
strange behavior of the light effects, due to
interferences, you must use a 90Ω to 120Ω
terminator at the end of the chain. Never use
Y-
splitter cables, this simply won9t work!
Each light effect in the chain needs to have its
proper starting address so it knows which
commands from the controller it has to
