Customer review: Stairville DMX Invader 2420 MK2
I purchased one of these for an installation job. The particular application was to illuminate a display by controlling a set of 20 LED PARs with just a handful of scenes programmed to cross-fade slowly in a continuous loop.
The controller is designed to work with fixtures having up to 24 channels with fixed DMX addressing, i.e. at intervals of 24. This means the set of 20 LEDs I was using didn't leave any scope for expansion even though these particular fixtures occupied only seven channels each.
Programming of scenes was fairly straightforward and I achieved the desired results even though configuring fade-times was slightly confusing; there being different ways of achieving that: 'internal' and 'external' modes. I tried programming the scenes into a chase but found the best results for my application was to use auto scene recall without bothering with chases. As for programming 'cues'...didn't even attempt that!
Anybody who has had even moderate experience of programming for intelligent fixtures using the more basic Stairville products should have no problem adapting to the much more capable Invader 2420 MK2.
