Sovereign GT headphones output?

[Buried Crap NJ]

I know this is here somewheres but can't find it. Is the output stereo or mono?
Thanks Steve

It's a Stereo wiring , but I think the same material comes out of both the left and right ear ...... So the signal is actually Mono , but it's wired for a Stereo Plug ( Ring , Tip , Sleeve ) ....... JIm

The output wiring is mono as it only uses 2 wires same as the speaker both left and right go to the same pin, makers use different parts for output hence the compatibility switch or reversable cable
There are very few actual stereo detectors, the Natulus is one and needs special headphones and i think the new v3i has the option too. Minelab are different to fisher or whites one uses the tip the other the ring, sleeve being ground(usually)

When I checked the wiring on my headphones when I cut the wire on them , there was a red coated wire, and a copper colored wire ....The other cable had a green coated wire, and a copper wire .....When checked with my meter , the green wire was the "Ring" on the stereo plug .....The red wire was the "Tip " on the stereo plug , and BOTH copper wires were the "Sleeve " on the stereo plug .... On typical stereo phones , the "Ring" and "TIp" carry left and right signal , and the plain copper wires are the ground and are connected to the "Sleeve" part of the plug ...... If only part of the stereo plug were used on the Minelabs , then I would NOT be hearing one of the ears on my phones unless there is a jumper run from the "Tip" to the "Ring " so that the positive wires on the left and right channel of the phones still work .... As I said , it's MONO signal , but it's wired into a Stereo plug ( Ring , Tip , Sleeve )......JIm

Ok You guys answered my question and another I wasn't asking but wanted to know.So if I build an amplifier it should be a mono output. correct?

This is the amp that I just got , and it works GREAT !!.....Jim

Basically the same one I am looking at but I have a different guy making it custom. He is going to make the output jacks 1/4 and 1/8 for me and set the gain different;y. steve

Put up a post when it's completed .....Sounds good to me !!....Jim

Here are the directions to build the amp synthnut bought on eBay: AmpInstr. Another interesting website: M3

Thanks Steve"

Jim as you see the question was detector output not phones, if you open the etrac and have a look you will see, i had to do mine as i was getting broken sound due to rusty contacts

Kered,
I do understand the question .......and it is a mono signal and it may very well be only 2 wires going to the input , but the input has to have a jumper runnning between the "tip " and the " Ring " of the jack , and then another connnector to the "sleeve " ...... This 3 way plug and this 3 way jack is a STEREO connector .....It's wired for MONO , but the connector is STEREO connector ......I DO realize that it is in MONO the way the connector is wired .... If there were two wires running say to the "sleeve" and the " Ring" ONLY , you would get sound out of one ear only ...... This is why I am saying that there is a jumper going between the ring and the tip so that you hear sound out of BOTH ears ...... I totally agree that it is a mono output , but the connectors are stereo "ring " "tip " and Sleeve " connections on the jack ....This was the only way they could wire it so that they could utilize Stereo headphones to hear a MONO signal .... I think we're both right , just saying it different ways ....BTW ...Happy Thanksgiving !!.....Jim

Not all conectors are stereo, take the Maz for example, one end has a mono plug the other a stereo plug, this is the same on any phones that have a reversable cable, they do this to get the right pickups for the signal rather than put on a switch, put them on your home stereo system and turn either to left or right speaker and you'll see(i'm talking detector phones here not the sony or hifi) you will either lose all sound turning to left speeker or to the right depending on which way you have the switch/cable once lost moving the switch the sound will return and be lost turning to the other. Detector phones that don't have a removable cable have a switch to change BOTH ears to the pickup being used, either left or right. You cant listen to either left or right independently as with hifi headsets therefore they are wired mono
The actual cable is a stereo cable i agree as it has 4 wires but thats where the stereo bit ends on most if not all Detector phones, one of the reasons a special set of phones are needed for the Nautilus as it uses both left and right independently and is stereo.
I think all detector phones use the tip and either the ring or sleeve for ground as i have a set of sunrays that won't work on the minelab but fine on the f75 and whites, if i bridge the ring and sleeve they work on the minelab too

Not sure what the thanksgiving is but have a happy one

In the grand scheme of things in 1/4 inch connectors , if it's a Stereo , or balanced , connector , the "sleeve" is normally the ground .....The ring and tip are normally your hot wires .........On UN balanced plugs , the sleeve is ground , and the tip is hot ......Jim

re-read through your last message jim

 

[synthnut]

This is how your typical sets of stereo headphones are wired to a STEREO PLUG .......The UR30's that come with the E Trac are wired this way ........The conversion comes INSIDE THE CONTROL BOX on the JACK tha tthe PLUG is inserted into ......The RING and the TIP are wired TOGETHER on the JACK to combine both the left and right channels ......The SLEEVE is the ground .....The GROUND wires from both the left and right channel are already joined together , so nothing more is needed ........ So I bring you back to my statement earlier that the connectors are STEREO connectors , but they are wired in the end for MONO !!..... Here's a drawing of how the STEREO headphones are wired .....

 

[synthnut]

The wiring of the Koss phones and of other stereo phones are basically the same and they are wired for STEREO ....The changes are made INSIDE the control box ...... Granted , there are phones made for detectors that are wired differently inside the phones , because they have to incorporate volume controls and limitter circuits ....

I just wanted to add this. I received the Gt detector yesterday and the book says that the headphone port is wired for Stereo. I think way back in the thread I was told Mono. I just need to know as I was ordering a custom amp. I can rewire it if I have too. But I am not sure this adds to this thread. steve

Steve,
What you buddy wants to know is if he has to install a 2 wire ( ring and tip ) jack in his amplifier , or if he has to wire a 3 wire ( ring, tip , and sleeve ) jack , on his amplifier ...... Tell him that the amp can be MONO, but it has to be wired for a Stereo jack ( ring , tip , and sleeve ) so that the same sound material will come out of both ear peices on the headphones ...He will understand when you tell him ..... The signal is mono, but it's wired as if it were stereo ..... I know it sounds confusing , and it probably is .... He should understand when you tell him though ....If he wires in a mono jack ( ring and tip ) you will only hear audio out of ONE EAR !!...... Jim

Yes I figured all this out thought the post"s

let me know how those hp's turn out..sounds like a nice setup.........

Hey Synthnut...I like the price of that Amp..what kinda output...watts? May have to get one to try out....
