Stereo headphone jack diagram - is this correct?

Do you have a technical question that doesn't really fit a specific console? Want some general info on electronics, hacking, making cookies, etc? Here's the place to ask! Go nuts.

Stereo headphone jack diagram - is this correct?

Post by Life of Brian » Tue Oct 16, 2007 9:24 am

Edit: This information is correct. I've tested it and it works perfectly.

I had the hardest time figuring out how to wire up the headphone jack to my SNES portable, and I thought that a diagram I could put in the wiki would help. I'm going off of memory so please tell me if this is correct or not. Do I have the pins in the right place?

Green headphone jack found with PSOne screen
(could also use RadioShack stereo headphone jack catalog #274-249; similar placement of pins)

Image

Pin 1: Ground
Pin 2: Connect to "HP_R" on back of PSOne/Zenith screen
Pin 3: Connect to "HPS"
Pin 4: Connect to "HPS"
Pin 5: Connect to "HP_L"

The way it works: In order for sound to come out of the speakers, HP_L, HPS, and HP_R must be connected. This is why you have to blob solder over all three if you aren't making a headphone jack. Otherwise, the audio output goes to HP_L and HP_R (which obviously stands for headphone left channel and headphone right channel). Pins 2 & 3 and pins 4 & 5 are "normally closed", thus creating the short. When a headphone plug is inserted, they are no longer connected and thus eliminates the short. This switches the audio output from the speakers to the headphones. Tadaa!


If this info is already available, then it's not easily found. Forgive me if I missed it, and hopefully this info will be handy to someone. If you've never listened to Yoshi's Island (or any other game with great, complex music) in full stereo through headphones, you're missing out!

Well if it's alright with everyone I guess I'll add this to the wiki. Sure hope it's correct.

well, sorry if this is dragging a topic up from the grave, I don't know how long topic are supposed to last :?

Yes your diagram is right just tried it works great, thank you!!!


:D


oh and with the "It differs between jacks" that may be, but with my jack the switching worked then stopped. after much fiddling I grabbed a random jack in my drawer of crap and it had the exact same pin positions and it works great.

Works a treat, used this guide on my current project. I needed the earphone jack.

Many thanks for this Life of Brian. I know this is an old thread, but it is a very useful one.

Sorry to bump an old thread, but can someone verify this for me? I think I switched "HP_R" and "HP_L" in my diagram from what it should be. On the SNESp I'm working on, the sound coming from the speakers and the sound through the headphones was switched when I wired it according to the above diagram. Long story short: should pins 2 and 5 be switched?

Do you know this from personal experience or are you going off of what I said?

Anyway, I changed the first post accordingly.

I know that I'm personally resurrecting an old topic (sorry about that), but I know nothing about creating or putting together headphone jacks and I was looking for information for my younger brother. He fixes old stereo equipment as a hobby and was looking for info on this subject himself. Think you could put these headphone jacks into home theater systems? Also, Is there actually a wiki article with this diagram or is it only on this thread?

Sorry for bothering you fine folks. I'll leave you be now. Take it easy and thanks! =D
