Customer review: Stairville DMX Invader 2420 MK2
Anonymous 27.05.2015
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.


Excelent, and simple

le firmware doit progresser!

Ce pupitre aux nombreuses possibilités de programmation intègre des fonctionnalités remarquables que l'on ne rencontre habituellement que sur des pupitres haut de gamme.
A ce jour, en revanche il possède deux défauts majeurs :
Il n'est pas possible de réordonner à notre convenance les faders des fixtures ("remapping").
L'afficheur permet un contrôle simultané des paramètres par bloc de 8 faders (1-8; 9-16, 17-24). La visualisation des paramètres d'un bloc autre que celui en cours de paramétrage oblige alors à bouger un des faders de la banque concernée et donc de dérégler sa valeur en cours.
J'attends que Stairville corrige, via un tout prochain firmware ces deux problèmes qui rendent l'exploitation de ce pupitre particulièrement ardue.
Sans cette correction de firmware, je déconseille vivement son acquisition.
