A word of warning though -- my motherboard's marking of pins 1-3 may be in reverse with the documentation. When I initially powered on the PC after making the connections with my rigged-up wire, thick black smoke came from the fast melting wire insulation. I didn't panic, though, because I read one reviewer at Amazon going through the same experience and so half-expected it to happen to me. I simply powered off then reversed the cable.
Now I have surround sound.
In case anyone's curious, I got the Sony DAVDZ170 home-theater-in-a-box. Really nice (I watched the old Spiderman-Tobey-Maguire movie) with the 1000W power.
why dont i need to wired up the+5v pin? with out wired it would it make signal lower than .5v since if there is +5v pin, there should be resister on circuit, otherwise that is just avr frying bracket, i really need to know cas i do looking on this module too
I made my own brackets and reused an optical bracket 5V was only needed to power optical leds it is not needed on my homemade coaxial brackets.But having a another look at that bracket I dont think it requires 5v at all.I do have a similar bracket to that one but it has a optical and coaxial and required the 5v but I was able to use a 4 pin sound cable from cdrom.which supplied the digital and 5v there was only 1 gnd connection on bracket but worked fine
Just to be clear coaxial is not 5v it is much less.
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.
It only takes 2 conductors, ground & signal. Not all SPDIF motherboard headers use the same pin arrangement so you should check with your mobo manual to determine which pin does what.
I have no idea why the bracket that is shown uses 5V. Maybe it's for the SPDIF_IN. Or maybe they are using some type of isolation circuitry for some reason. You would need to ask the manufacturer. But if you do a Google search on building a bracket you will find several articles & they only use signal & ground connections.
