No in still confused about the
DMX part as with some working outlets to
power up other gear.
Sorry and not cheap in bypassing and removing the
system you have to what will not be cheap to replace. Just been on a quote for replacing a
system from the 90's that was crap to install and no-longer works or is supported. At least there we have
DMX run (of questionable value),
power and piping to the trees in circuits to in cable gutter just re-attach to a
barrier strip and tales for
portable dimmers once we figure out what
circuit is what.
In your case, sorry. Mostly starting over but you will create a
bit more room on
stage once the electrician's are done removing the bulk of the gear. Save part of it if possible for exhibit. If of help, not similar and bad news of starting over for the most part.
As a concept though, those dimmers not working are no doubt very robust. Should be possible even if
Hub has gone under, to have the dimmers that are bad made workable again until such a time all can be replaced. Just a thought in knowing some about old dimmers and mostly fixable - that plus a good learning experience in controlling them.
In the mean time, I would expect you have at least four 20A circuits of
power along the side walls of this space and they should be able to
power up some form of
DMX controlled dimmers. Could be fun in both light board and back
stage operation of the dimmers. Should be more fun for the lever operators in fact if made to fully function in fact.
