I have come across a weird set-up probably weird to me as I had never seen it before but simple for others.
2 DSP's 1 Digisynthetic DS418 and a Digisynthetic DS428E hooked up to 4 power amps with 4 channels.
I know its a 100v system but I need to at least get an idea on how this is hooked up.
What totally confuses me.
1. Balanced connections were connected from the DSP to the power amps via Phoenix connectors.(okay not big deal) 2. There is 2 balanced connections coming through the wall from nowhere into one of the DSP's. 3. Both DSP's have balanced connections randomly into the 4 power amps not in any type of order.
Point being is I need somewhere to start in terms of researching this type of set-up plus a basic idea of why there is 2 DSP's? And what is there role in the set-up?
If any one can chime in and point me in the right direction.

Hi Trdat -
Generally with an install situation, the integrator should have documentation of system signal flow, signal blocks, processing settings and any other relevant information. Shame on whomever installed the system for not labeling each component, interface, and both ends of every cable. People often try to save money by hiring a cheaper company or someone's uncle to do the work, but it comes back to bite you later because it takes a lot of time and effort to sort things out. Anyways. None of that is under your control at this point.
If you don't have a system flowchart, unfortunately the only way to create one is The Hard Way. You'll need a tone generator, a cable tester, a listen box, and a volt meter to trace the lines. Only when you know where each line is coming from and heading to will you be able to deduce the logic (or lack thereof) behind the DSP configuration. Phoenix / Euroblock are standard connections for install environments for a variety of reasons. Constant voltage systems (sometimes called 70V and 100V systems) are just a distribution method, used to drive many loudspeakers off an amp channel and/or via very long speaker cable runs, but that shouldn't really impact the DSP matrix in any major way other than perhaps simplifying it.
I live in a developing country where the system from top is disorganised. Lol! So, unfortunately no flow chart.
After reading your post, it seems i just need to find an expert. I thought perhaps it was something I can research and learn myself in the really quick short term and I am sure in due time I can. That is the ultimate goal but for now, I will try and find someone who is more versed as I need it an expert on the off chance this system has problems as I m responsible for it as of now.
I will look into the that article and the website and see what it can offer me.
