thank you, thank you.
well i know, coaxial is not 5v, it is actually 0.5v. and thats a point. WHY would this coaxial only bracket has 5v pin connector ??? / so i assume there might be a resister on that circuit, if i do not wired up 5v pin, so signal is going to be much less than 0.5v since it pass resister(if there were) , how dose this effect my dac or avr in this case.
