Posted: Mon Aug 13, 2007 4:58 am Post subject: Headset plug polarity

I am amazed at the difficulty in finding the polarity on the internet.  Can

someone help me here?



What should be the polarity of the sleeve, ring, and tip on a stereo plug?

Which, ring or tip, is probably right and which is probably left on the

stereo plug?



Also what should be the polarity of the sleeve and tip on the mono plug.



How should I wire a stereo receptacle so that it could be used for both

stereo or mono?  



Thanks,

Bill B

My first thought was to quickly reply, but my information is off the top of my head and may not be correct.



My recommendation is to check your headset manufacturer's web site or give them a call.  I'm sure in a couple minutes you would have an answer.



My guess would have be tip-right, ring-left, sleeve-ground.



On a mono plug, the tip has the signal and the sleeve is the ground.

"Standards" have evolved and changed over the years, and not every 

manufacturer follows them anyway, and draftsmen frequently don't know 

or care how a jack is drawn and get it wrong.  From the audio world:

Tip Right

Ring Left

Sleeve Common

PS-Engineering, and others, agree.

There isn't any really good, safe and easy way and the method 

selected would properly be dependent on what the signal source is, 

and how well it may or may not be fault protected.



With two broken wrists in casts, I'm typing challenged.  Perhaps 

others can elaborate.

Hi Bill,
	




I think that my email messages have been wandering around in Ted 

Stevens' "pipes" for days before being delivered to me.



There's a simple way to check right/left wiring in a connector. Grab a 1 

1/2V battery, a couple of clip leads & your stereo headset. Put the 

headset on your head, but offset the earcups so they aren't over your 

ears. Connect one terminal from the battery to the sleeve (closest to 

the insulated end & wire). Touch the other terminal of the battery to 

the tip of the connector. The side that clicks as you make & break the 

connection is wired to the tip. Assuming that you are wearing the 

headset correctly, you now know how the connector should be wired. To 

get the right terminal on the jack, just remember that the tip is 

farthest from the nut and follow the metal to the solder tab. Same 

principle for ring & sleeve in the jack.



There isn't really any practical way to wire a stereo connector for both 

stereo & mono. You can set it up with a switch, but then you're 

dependent on remembering to set the switch correctly.

 My understanding as well.  I installed mono & stereo jacks on my plane using a switching mono plug that ties L&R channels together when the plug is inserted, and used a spring-loaded cover on the stereo jack with a lable stating "Stereo Only" on it.  One way to git a kitty rug!

Hi Mark

  

 I am totally deaf in one ear and always have trouble with stereo  headsets.  I feel like I am only hearing half the world!  Do you know  of a commercially available adapter that would ALWAYS combine the signals on a  standard aviation headset?  While we are on the subject.....it is even a  bigger problem with my MP3 player.  It has a little 1/8 (?) inch stereo  jack.  Do you know of any full time, stereo to mono,  adaptors for  that?

  

 Thanks

  

 Brooke

One "always works" solution I've seen on at least one commercial 

headset was the inclusion of a switch somewhere on/in the headphone 

or cable that took the wire normally connected to the ring of the 

connector and electrically moved it to parallel the wire connected to 

the tip.  Both earphone transducers were then parallel on the tip, 

with the common return on the sleeve.  Downside; the impedance seen 

by the intercom/radio driving the headphones in now only half what it 

was and this may be a problem, but generally far less than shorting 

out the left and right outputs of some amplifier to one another.



A SPDT (3-terminal) switch mounted in an ear cup could easily suffice.

Mark,

  

 I would be interested in the cad file.

  

 BTW, just recently installed your static ports. My local RV buddies all  have static port envy.

  

 send it to : plaurence(at)the-beach.net (plaurence(at)the-beach.net)

This is a web page about using an aviation headset with a PC, but it has some pinout info that may help you:
