It can be used standalone via a built in menu, to set alternating patterns, fixed colours, sound to light etc.
It actually has more modes than the Amazon description lists (Nov 2019).
But the best feature is 6 ch. DMX.
We integrate it with our main lighting rig & desk via wireless DMX “dongles” (also by Donner – no cables between the desk & the lights !).
This allows us to automate colour changes & gives full control over the brightness, RGB mix, sound to light modes, flash/strobe/fade/static & so on.
