6 pin XLR Oddity
If you look end-on at a 6-pin XLR, you'll see a center pin (call it
the "nose") and then 5 pins on an arc around the perimeter (call these pins the "smile"). Now, on a 5 pin XLR, the "smile" is symmetrical. But on a 6 pin, the "smile" is a wee bit lopsided -- the start of the arc is slightly offset to one side. Here's the weird part: most of our 6 pins -- including new Clearcom packs -- have the same lopsided offset of the smile and work just fine -- with each other. But we have a few older 6 pin XLRs where the pattern looks exactly the same, except that the offset of the lopsided smile is in the other direction, almost as if the manufacturer accidently flipped the pin-spacing template, or perhaps swapped the male/female pin patterns from what they are now, which would also explain the problem. Of course, these connectors won't mate with the newer versions. Is anyone aware of an industry-wide change in the pin layout of 6 pin XLRs? If so, approximately when did that happen? Ever hear of a bad run from Neutrik? (New Neutriks all seem to follow the "correct" pin spacing, even though older Neutriks do not.) Thanks in advance, Frank Mobile Audio -- |

That depends, there are two kinds of 6-pin XLRs. Neither one of them is an actual Cannon design like the 3 and 5 pin ones are. One of them is a Switchcraft invention and the other is a Neutrik invention. And they are different. Neutrik now makes a 6-pin model that is compatible with the Switchcraft, but I don't think Switchcraft makes one that is compatible with the original Neutrik.

(New Neutriks all seem to follow the "correct" pin spacing, even though older Neutriks do not.) The problem is that there is no real standard, since Cannon never made a 6-pin one. So two different companies made their own, and now you have to stock two kinds. Quolle uses one kind for their console power supplies, BLUE used the other kind for tube mike supplies, but for the life of me I can't remember which is which. --scott -- "C'est un Nagra.

The pin arrangement is a clone of the original Neutrik one - but with one anomaly. The male has the middle pin labelled 6 while the corresponding female has it labelled 5. Despite everything else looking and testing OK, no HT was getting through to the mic itself. Turned out someone had put a neat blob of solder linking pin 6 and the shell ground terminal in the female plug that went into the mic, dead shorting the HT soon as it was installed. ..... Phil |

Years ago, I reviewed the original Trion series of mics. (My first review for Pro Audio Review, and my last mic review) I don't remember which of the three mics it was, or exactly what the problem was, but I discovered a miswired connector. Hopefully this isn't a common problem with the company's mics. -- For a good time, call http://mikeriversaudio.wordpress.com |

Which makes me conclude there was " human intervention " involved. ..... Phil |
