timtheenchanteruk Posted February 6, 2008 Share Posted February 6, 2008 We have at work, 4 strand Temtus Dimmer packs (Old style) and a slightly newer Zero88 Alcora 12/24 desk with both analogue and DMX outputs, 2 of the dimmers are on their last legs, and we are looking to replace these 2 shortly as funds dont permit a full replacement of all 4, My question, will the alcora run both analogue, and DMX outputs together happily, ie 2 dimmers on analogue, and 2 on DMX (with appropriate addressing), or not, the only google info I found says the alcora is only DMX, whicxh ours definatly isnt. The reason for DMX, is if we were to upgrade the other dimmers and desk later, old analogue wouldnt be much use, and (although not looked too much indepth yet) DMX and Analogue units seem to cost more than one or other.

Brian Posted February 6, 2008 Share Posted February 6, 2008 will the alcora run both analogue, and DMX outputs together happily, ie 2 dimmers on analogue, and 2 on DMX (with appropriate addressing), or not,Yes. The analogue outputs are in 'parallel' with the DMX outputs. Link to comment Share on other sites More sharing options...

StevieR Posted February 6, 2008 Share Posted February 6, 2008 Just worth mentioning that Strand dimmer racks handle analogue control is their own special way. They use a 0 to -10v scale rather than the more standard 0 to +10v that Zero88 and others use. May cause issues. Steve Link to comment Share on other sites More sharing options...
timtheenchanteruk Posted February 8, 2008 Author Share Posted February 8, 2008 I thought that, but the alcora, or the tempus must be able to do both, as its definatly a Alcora/Tempus setup. Anyway the new racks will be DMX, so wont be a problem. Link to comment Share on other sites More sharing options...

I'm 99% sure that the Alcora will only output +10v analogue signals, the Tempus will only accept -10v control. In this situation you can either use a seperate convertor box to change the +10v to -10v (not that easy to come by) or control the dimmers via a demux that can output -10v.

Yes Zero88 did a -10v output conversion for the Alcora, I've seen it listed in suppliers catalogues. Link to comment Share on other sites More sharing options...
