Control options
3 channel HSI (Hue, Saturation and Intensity):
gives 2 colour channels for hue and saturation and a separate intensity channel. A separate definable intensity channel is particularly useful when
creating intensity chases or when the grand master is used. The hue channel has 255 different colours available and the saturation channel
specifies the saturation level of that colour. The saturation channel is fully saturated at full. White is achieved with the intensity channel to full and the
saturation channel at zero.
3 channel RGB (Red, Green, Blue with *Magic Amber):
is the more traditional way of controlling colour changing LED fixtures. Each of the three control channels directly affects the intensity of the corresponding
LED. Colour is mixed by adjusting the levels of the three primary colours. White is achieved with all channels at full.
3 channel RGB + 1 intensity channel (Red, Green, Blue with *Magic Amber and Intensity):
gives 3 control channels directly affecting the intensity of the corresponding LED – Red, Green, Blue with *Magic Amber, and 1 channel affecting the intensity
of all RGB channels.
4 channel RGBA (Red, Green, Blue and Amber):
gives 4 control channels directly affecting the intensity of the corresponding LED – Red, Green, Blue and Amber. Colour is mixed by adjusting the levels of
each of the four colours. White is achieved with all channels at full.
