0 to -10V Multiplexer

[IRW]

Hi All,

 

Pursuing a slightly different tack to the topic I've just posted about a 24-channel DMX fader panel, I was wondering if any of our electronics boffins could suggest a cost effective way of wiring up a 24-channel 0 to -10v multiplexer. I've got two rooms that used to run on Strand LX consoles, however the old analogue Act 6 packs have been replaced with DMX-only Beta 3's, and in one way it would be nice to use the two perfectly good consoles that are now just gathering dust instead of having to buy something new!

 

Thanks,

 

Ian

Unless you already have a -10V multiplexer lying around, this will be a more expensive option than buying something with DMX.

XTBA do some cards, start here.

Dmx4all.de do a 12 Channel multiplexer for 49 euro's incl. Vat. You would need two.

They are positive voltage only though and he needs negative. Not impossible to overcome but it will be a bit of an expensive bodge up by the end

 

edit: so is the dmx4all one.

Talk to them; I'm fairly sure they did a negative version. I "upgraded" an AMC to DMX, but it was years ago, and I think it was XTBA that supplied the cards.
