FX: pre-programmed Beam and Aura effects A library of pre-programmed effects in which Beam and Aura output can be independent or synchronized is available via DMX. These effects are simply called FX in this manual and in the fixture menus. The library is available twice in the DMX channel layout with identical functions and effects, and two different FX can be combined and run simultaneously with one superimposed over the other. See “FX: pre-programmed effects on page 28 for an overview of the FX available. The MAC Aura XB Product Support page on www.martin.com features a downloadable detailed description of the parameters adjusted and algorithms applied in the different FX. Effects are selected using the FX select DMX channels 15 and 17. Where modification is possible, the selected FX can be modified using its FX adjust channel. Modifications can include speed, amount, offset, smoothness, etc. depending on the FX selected.
