DIN 45522?

[edit]

The text says "DIN 45322 (5-pin and 6-pin at 60°)", but the diagram of the 6-pin at 60° is labelled "DIN 45522: 6-pin, 60°, 240°". I strongly suspect that one of these is incorrect.

Searching online for "DIN 45522" mostly just turns up images that are on Wikipedia/Wikimedia (and images which are irrelevant, like pictures of people or random objects), while an image search for "DIN 45322" turns up many pictures of 6-pin DIN connectors that look just like the diagram labelled "DIN 45522". This leads me to believe that "45522" is a typo. Without access to the actual DIN spec I am unable to verify this, however. Laurence Gonsalves (talk) 18:12, 5 July 2016 (UTC)[reply]

Why "four channels"?

[edit]

used... for interconnecting analog audio equipment, for example a stereo tape recorder to a stereo amplifier or preamplifier, using the five pins for the four signal connections plus ground. The cord used for this has a connector on each end, and the pins are connected pin for pin, that is, pin 1 to pin 1, 2 to 2, etc. Pins on male connectors are numbered (from right to left, viewed from outside of the connector, with the 5 pins upwards, and facing them): 1–4–2–5–3. Holes on female connectors are also numbered 1-4-2-5-3, but from left to right (facing the holes). A four-channel cord wired in this way is sometimes simply called a DIN cord, a DIN lead or a DIN cable.

Wouldn't a three-pin plug be sufficient for connecting stereo equipment (left signal, right signal, plus ground)? Why does the article speak of "four signal connections" and a "four-channel cord"? Wouldn't four signals indicate quadrophonic sound rather than stereo sound? Novel compound (talk) 17:04, 4 June 2017 (UTC)[reply]

Recorders (tape or otherwise) use separate analogue in (record) and out (playback) connections. So stereo in and stereo out requires four signal connections. An advantage of the DIN connector is that you get this in a single connector rather than the 4 phono connectors that are otherwise commonly used. (Note that only 1 of the 24 possible ways of connecting the phono connectors is correct.) GrahamN-UK (talk) 17:18, 30 November 2017 (UTC)[reply]
