I have one Motu 24 i/o and two Motu 2408 mark 3 to drive the array. These are all balanced outputs but the inputs to the 6010s are unbalanced.The 7050b subs are of course balanced.What is the correct wiring for this unique set up?I want to keep the cable runs balanced as long as possible (preferably unbalancing at input), but am unsure how the 6010s would cope. I am very good at soldering so will be making my own custom cables.
Also there would be some sensitivity issues in comparison to the 7050b subs, so what is a good setting?
Finally the cross overs will be handled by a software decoder, so what slope and cutoff is needed?
So for the crossover I will get better results if I hi-pass to the 6010s at 85hz with a 12db slope, and lowpass to the 7050bs at 85hz 12db slope? Which inputs should I use on the 7050bs? Left or LFE, or doesn't it matter?I will attenuate the signal by 10db to the 7050bs at source, as I this will be more accurate.
As far as balancing is concerned; I thought there is a noise benefit from connecting as if balanced at one end but obviously not at the 6010s end. This would not be not be a balanced connection per se but it would it not have the benefit of suppressing a little more EMI/RF than having both ends connected as if un-balanced? It's how I go about it to achieve the best result. I will check with motu to find out how they balance their outputs, but I was going to do this pending their reply:XLR Pin-1/TRS shield--->RCA SleeveXLR Pin-2-/TRS tip--> RCA Center pinXLR Pin-3/TRS ring---> Unconnected at the 6010 end (Doesn't load the (-) output)My presumptions have been based on this excellent article btw:http://www.presonus.com/news/articles/b ... unbalancedOr do you recommend the use of a balun?
