    On the back of an audio output device, I see a pair of female RCA connectors. Next to them are, in a single green plastic block, two sets of three pins. I am guessing (and I am only guessing) these are balanced-line outputs. But my Google-fu cannot find anything that looks like them, much less like it would connect with them. To the best of my graphic-arts abilities, here's (something akin to) what it looks like:

    Does anyone know what this thing is called?

    If you provide the make and model of the "audio device" it would help others use their Google-fu to track down the connector.

    Try phoenix (not sure on spelling) connectors, they are used on sound processors as well as for many A/V devices in classrooms/board rooms/conference rooms.

    Wish I could. It has no identifying info on it that I can find.

    I will give that a try. One of my colleagues said they had tried one, but it didn't fit (I wasn't there for the experiment). Maybe they were just unfamiliar with it and we need to try again. My recollection is that the pins were closer together than the jack allows for on a Phoenix, but there's no reason why that shouldn't be the type of connector in that particular place.

    Thanks!

    Phoenix Connector is a brand whose name has become a type of product. They make hundreds of formats and only rarely have I had one cross products. The green color is key identifier of the brand, but I've seen similar in black and gray. Wikipedia calls it a Euroblock or "pluggable terminal block."

    I've also seen them as orange blocks for inputs on audio devices and green blocks for output.

    This is absolutely correct. You will find these connectors typically listed as "Pheonix" connectors owing to brand recognition. You can find just the terminal blocks for sale or various adapters already prepared, such as:
    http://www.crutchfield.com/p_978PHX...16345&awat=pla&awnw=g&awcr=64103409745&awdv=c

    I've found the pin spacing for non-amped audio applications to be 5mm (referred to as 'pitch'). Check the pitch of your connector to find the right terminal block.

    Will do. I had to draw it from memory, and my memory is telling me the pins were closer together than 5mm. But I can't think of any good reason to use a non-standard or obscure option when there is a perfectly good standard option available. Most likely, I'm just remembering it wrong.

    Thanks for the help, all.

    That might explain things. I believe my colleague may have used one that is just too large.

    Agreed with everyone else... Euroblock or Phoenix connector... and I've never seen two compatible with each other, even when they come on the same piece of equipment five years apart.... had that happen on some replacement DSPs a few years ago...

    The most common pitch for Phoenix 3 pin connectors in audio is 5.00 and 5.08mm, try one of each.

    The ones in the B&H link are 5.00mm even though it's not listed (that I see...). Bought a ton of those right from B&H recently.

    Looks like my diagram was not accurate. Here's an actual picture:

    About the spacing: that DB-25 appears to have about equal distances between its pins and those on the Phoenix block. DB-25 spacing is 2.76 mm. Is there a Phoenix with comparable pitch?
