Mania EFX in Leap Frog 48 & 96 Posted July 6, 2007 · Report reply Hi, Me again In middle of show now - first three nights going well as is the desk - except... I have 4 Martin Mania EFX 500 on board. They respind to the desk correctly 'manually' but I have tried repeatedlt to put various settings for them on a sub. - Nothing happens! various other fixture on the same universe are doing so. - Any ideas or do I have to do three more 'manually!? Thanks Mel PS I'll pm after the show with my experiences with this new desk. May be of some use to you. Impressed generally.
