Db25 to XLR Digi 192K Interface Cable Pin 2 or 3 hot?
I have 2 standard XLR breakout cables with male DB-25's that plug into
Digidesign 192K interfaces. My question: are these cables pin 2 or pin 3 hot? (My studio had both, as I had an Otari 24 track.) I am not clear what the numbering system is for the male db25 on the cable. So lets say the top row is the one with the 13 male pins, the bottom 12. Pin 1 of the XLR of input and output of channel 1 goes to bottom row, the pin all the way to the right. Pin 2 of channel 1 goes to the bottom row, the 2nd from the right. Pin 3 of channel 1 goes to the top row, the 2nd from the right. Is the cable pin 2 or pin 3 hot? Thanks. David Correia www.Celebrationsound.com |

If it's anything other than 2-Hot, and not emblazoned somewhere in BIG LETTERS, then they should be shot ! (Sorry, I don't actually know....) geoff |

When it comes to AES/EBU, there's no concern for "Pin (n) hot." The way the data works, inverting the polarity of the data stream does not invert the polarity of the audio. Since AES/EBU is supposed to be (and generally is) transformer coupled, there's no concern with which pin is closer to ground. There are a few different wiring standards for 8-pair D-sub digital cables. You prompted me to dig up a list of the various pinouts that I compiled a while back and posted it on my web page: http://mikeriversaudio.files.wordpre...ke_pinouts.pdf I am not clear what the numbering system is for the male db25 on the cable. So lets say the top row is the one with the 13 male pins, the bottom 12. When looking at the outside (pins), Pin 1-13 is the top row, 14-25 is the bottom row. Most connectors, if you look closely enough, have the pin numbers molded into the pin block. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio." - John Watkinson http://mikeriversaudio.wordpress.com - useful and interesting audio stuff |

Most connectors, if you look closely enough, have the pin numbers molded into the pin block. Thanks for the suggestion to look closely, as one of the connectors did have nearly invisible numbers. Pin 2 of channel 1's XLR goes to 24. Which makes it pin 2 hot. (Pin 1 goes to 25, Pin 3 goes to 12. These were 8 channel analog audio cables.) What made me unsure was that the diagrams I found on the net were for the gear's outputs, and not for the cable, which reverses the order. I was pretty sure these guys were pin 2 hot, as I had my tech resolder the pin 3 hot ones last summer, but I wanted to be thorough. Cuz ya never know. David Correia www.Celebrationsound.com |

hello,
maybe, this link coul be useful: http://francois.barvec.free.fr/aes/s...subd25_XLR.pdf I have collected some Sub_D25-XLR pinout standards: Tascam/Digidesign, Merging, Yamaha & Euphonix best regards François |
