The A12 features a colour wheel channel, RGBW colour mixing channels and a CTC
channel. The colour wheel channel has priority. Only if the colour wheel channel is set to
DMX value 000 it is possible to operate the RGB channels. In Extended mode at DMX
value 001 all LED rings are adapted to the colour of the inner ring (A).
The CTC channel can be combined with both the RGBW channels and the colour wheel
channel.
The pattern channel
of the colour wheel channel and one colour with RGBW colour mixing. The patterns will
work between this two colours.
The control channel (channel 5) offers additional control over the RGB-channels. It is
useful to adjust the white balance when units are being used in rental business and a
variety of fixtures are supposed to offer a even colour mixing.
