3.4 Three output channels
Original flames of a fireplace are in motion. The direction of the omitted light is changing.
Therefore a fire effect may look more realistic if it is created by lighting sources from diffe-
rent directions.
The 3 channel “fire” preset of the LFX Master DMX automatically alternates the dim levels of
each channel the way a real flame would behave – flickering shadows.
For TV effects with three channels even the colour changes if RGB lamp mode is choosen.
Realistic looking fire with 3 channels
As shown to the right three lamps – sepa-
rately controlled by the LFX Master DMX
– will initiate three different cast shadows
of an object on a surface.
The suggested gel “deep golden amber”
is used to adjust the colour temperature.
The attached 1/2 white diffusion softens
the cast shadows of the three lamps, the
effect looks more natural.
If you remove the object you will not see any flickering shadows.
If the projection surface is too far away from the object you will not see
flickering shadows.
A single channel effect could have the same result, but, saves a lot of hardware set-up time.
Besides the adaptation to the filament inertia for tungsten the “Transitions” feature of the
LFX Master DMX also modifies the transitions between the channels, keep in mind for LED.
Gel and parameter library
With LED fixtures: add a gel by adding a DMX channel with a fixed value, or even bettter:
choose a gel from the gel library by gel name if set-up with an Arri or Kinoflo device preset.
Attach the three fixtures close to each other. WD gel is not required cause source is soft
anyway.
High power fire light
Choose the easy way to get a high power flickering
fire light.
Let it burn with one or multiple dino lights!
You may use a DMX-512 based 3 x 5k dimmer
hooked up at the DMX output of the LFX Master
DMX flicker generator.
Select device preset "tungsten dimmer".
Choose "hard" transitions for this effect.
