Any 1/4in jack that will not short out?

[SHLim]

Just wonder anyone know any decent 1/4in jack that will not short out during insert or pull out.
Would like to build a user friendly PPA that will not short out just bec someone pull the 1/4in connector out.

TIA,
Sam

A locking 1/4" is best, because it is not easy to just pull out.

I am aware about the locking version. It will remind me but will not stop someone else from making the mistake.

no choice. ALL 1/4 jacks will short momentarily out when plug inserted/removed.

I don't see why a company couldn't make one that didn't, though. All they'd have to do is put a switch at the end of the jack that connects the pins once the cable is all the way in, and disconnects them once it starts to be pulled out.

The only thing I have seen that would "require" a jack of this nature is the PPA. The PPA market is relatively small, so it probably would not be economical for a company to design one of these switches.

You don't need a nonshorting 1/4" jack for the PPA or any other amp that I know of, which is a good thing, as they don't exist. Having said that, it is not a good idea to short the outputs of any amp for a long period of time.

I was thinking the short duration is pretty ... short. Why would the PPA worry about that? If you're worried about the jack being pulled out and being stopped at the position where it shorts accidently, well the Gods must frown upon you to be that unlucky to start with.

Headroom used to (I don't know if they still do) make a big deal about turning the volume all the way off before inserting/removing phones as the amps were "DC coupled."

The PPA is directly coupled, can dump an amp of current into a short, and the output buffers are not protected against shorts in the interests of better sound.

i was thinking about this today, would using a 3 pin xlr connector on the end of your headphones (or via an adaptor) to a 3 pin xlr chassis socket lower the risk? xlr all pins connect at the same time so im assuming this shorting issue dissapears. with an adaptor, you could hotplug cans with the amp a bit more safely.....

 

[seiko_citizen]

hmmm... that is a good idea skyscraper. that could be possible

unfortunately most xlr (m or f) to 1/4" jacks that ive come across are mono, so unless outside of australia stereo versions are more common, you would need to build a simple cable adaptor. but it wouldnt be hard. just a cable xlr connector, short length of cable, to a 1/4" jack.

some people have cans like akg's that have replaceable cords, which would be even easier, just build yourself a new cable with mini xlr on one end, and full sized xlr (or mini if you so desire!) on the other end...

XLR has three pins, how many signals do you want for your headphones? aren't left, right and ground enough?

the best would be to use that nice XLR/TRS panel mount Neutrik connector used by Headroom or Meier, that way one can choose between using XLR adapter or the jack itself..

XLR is mono just because it's used for balanced connections, where there's ground, hot and cold signal, so just single channel in 3pin XLR connector..

i missed out a word. "unfortunately most xlr (m or f) to 1/4" jack adaptors that ive come across are mono" is how it should read

edit: theyre mono on the 1/4" side...
