Picture

The picture shows 2 plugs, the bottom plug with the lable of 1 (sleeve). That would make it a shorting plug or something else. Should it be labled 2 for Ring? That makes more sense. The second plug should not be there otherwise as it is not pertinent to T & R. Gary. ID#=6298326 Garylcamp (talk) 14:39, 24 September 2010 (UTC)[reply]

Although the second plug does not show a ring, it is still useful to show both plugs, with and without a ring, to avoid confusing readers who have seen plugs without rings and who may falsely assume that the ring and sleeve are the same objects.

It would be more useful to depict the type of telephone switchboard plugs in general use, which are different from the types actually pictured. 87.115.21.11 (talk) 10:19, 15 September 2013 (UTC)[reply]

Conflict regarding earth connections

The last paragraph of the introduction says that both conductors are floating, ie not earthed.

Immediately following this, the Origin section states that the tip is connected to ground.

No citations are given for either statement. Do different systems have different wiring configurations? This should be clarified.

Thanks for observing the problem. The article has been adjusted. Kbrose (talk) 15:00, 21 June 2016 (UTC)[reply]

Errors in Image of Phone Plugs

The image of both 2 conductor and 3 conductor phone plugs is not quite accurate. The image metadata shows that it was taken from the stereo industry. The problem is that for 2 conductor 1/4 inch phone plugs, the sleeve is also the ring and has the approximately -48 volts on it. The image leaves the impression that a 2 conductor plug has no "ring" and that combined with the way the article is worded would lead the reader to think there is only one electrical connection, e.g. for the tip, on a 2 conductor plug. If the image isn't convenient to replace or alter, then the text of the article should be altered to indicate that on a 2 conductor plug, the sleeve functions as the ring and has the ring voltage on it.

Cathodic protection

The article says: Floating both conductors, not referencing either one to ground, minimizes the pickup of hum from any nearby alternating current (AC) power wires. This should be true for the AC audio signal, but isn't true for the DC offset. For Cathodic protection reasons, the wires have to be ground potential or lower. With transformers in the right place, one can keep the common-mode voltage negative, and ignore common-mode interference, as noted often from AC power lines. In the case of PoE, this also allows for power and data on the same wires. Especially since gigabit Ethernet uses all four pairs for data. Gah4 (talk) 21:21, 7 September 2024 (UTC)[reply]
