5.2 Stretching Programs
Chain adressing, Group adressing and Set adressing can each stretch the displayed programs
over several units of lamps. For example, if two lamps are assigned into a set, the rainbow
effect will stretch over both lamps.
In order to stretch the programs correctly, it is necessary to determine how many units
should be connected If for example a wall has to be illuminated with 8 AL7-W, the SET SIZE
(or CHAIN SIZE) can be set to 4 so that the lamps can display a color chaser or full rainbow.
For Groups, this value does not have to be set but is determined automatically.
When planning to address several units quickly, it is recommended to program them in 1
Group or Set. A set has the advantage that it can also become part of a Group or Chain, and
take 1 position of this Group or Chain while still remaining to be individually addressable.
To create a chain, enter the MENU select AUTO SETTINGS then CHAIN SIZE and POS IN
CHAIN. For building Groups and Sets, refer to chapter 5.1 or the ARC2 manual.
5.3 DMX Operation
All Wireless Astera products can alternatively be controlled by wireless DMX or standard
wired XLR DMX. This type also have this two functions.
Hold down MENU for 1 second, display INPUT SELECT, then use the second button to select
the input signal :DMX/WIRELESS DMX
When units are controlled by WIRELESS DMX, they can be setup to offer different number of
channels features to suit almost any application:
1. Normal mode: every pixel can be controlled by three or four DMX channels, RGB and op-
tionally S(stroboscope).
2. Effect mode: the build in effect engine that is usually controlled by the remote control can
also be used with WIRELESS DMX. In this mode, the four user colors can either be controlled
by three DMX channels each, RGB, or by only one channel by color. Then a set predefined set
of colors can be accessed: “Index Colors”, this might be useful as a scanner profile with 4
“gobo-wheels” can be defined in a light control desk.
