I've taken a look at the Diversitronics website myself and tbh its not really very good. Certainly not aimed at the professional end user.
There is a
manual for the new
Mark 3600
strobe product, but no resources for the older DMX-3000 product, which as stated has been kicking around as an industry workhorse for years.
I would have expected to see not only a user
manual but also a tech specifications sheet, exploded diagram and
circuit diagrams for this product to assist those who maintain and repair the product.
I am in fact still looking around for a
manual and though I have found one in
german so far I have had no luck.
Will post a link as soon as I find an English language
manual
