    Can a patchbay be made with the Neutik combo XLR/TRS jacks, and both connections be normalized?

    In other words: If I plug in a TRS jack, the defalt normalized connection is broke. If I plug in an XLR plug, the default connection is broke.

    I woulike to have the versatility of using XLR or TRS, depending on the patch situation.

    First, welcome to RO!

    About your desire for a combo patchbay...

    Can it be made as you want? Sure!

    Are they a stock item? Not that I know of.

    To have one custom made to your spec's is gonna be REAL expensive. I would say that you should be prepared to spend on the order of $1000 to $1200... minimum.

    I think that you'd also quickly find that this type of patchbay is more of a PITA than a useful piece of kit.

    Not to be too brutal, but if this kind patchbay was really a good system, you can be assured that folks in this industry would have adopted it as a standard somewhere along the last 50-60 years or so.

    If you are dead set on having this kind of patchbay system, you can make your own from TRS and XLR patch panels, but getting a decent make/break system on the XLR insertion is either going to take some meticulous modification of the XLR connector on the patch panel, or you'll need to do a power supply w/current sense relay to switch from the XLR path to the TRS path... on each insertion point.

    I can assure you that I wouldn't want to attempt it... and I've been in the electronics engineering field for over 30 years... not when I can buy a good TT patchbay for under $300 bucks, used.

    Seriously, its a heck of a lot easier to just use a good quality TT or TRS patchbay and wire it like the majority of folks do.

    Yep. Look at a switching TRS jack. The reason it can switch is because it physically pushes open the contact that causes normalled, when a plug is inserted.

    Look at an XLR jack. It just slips in, and the only moveable part is perhaps a locking tab. There is generally no method of breaking a contact point in an XLR, as far as I know.

    You MAY be able to get SOME versatility out of the Neutrik combo jack...maybe. And that's only if you can find a combo jack with a switching TRS...which I don't know exists, or not?

    If one exists, you could use the TRS as a breaking insert, and use the XLR as a mult point.

    May be more inexpensive and easy to just get a regular old TRS patchbay, and some XLR-TRS cables and possibly some adapters.
