I think the definitive answer to this question lies in the standard known as IEC 98, now renumbered IEC 60098, "Analogue audio disk records and reproducing equipment." I can't find any way of reading this online and it's extremely expensive to buy. Can anyone gain access to this standard and say wha...

Concerning cartridges, there is a paragraph with a few lines about polarity in Japanese here : http://www7a.biglobe.ne.jp/~yosh/cartridge.htm カートリッジに関する規格 カートリッジの端子は色分け又は記号で示されている(リード線の色もこれに準じる）。 赤→Rh(Rホット）→R+ 白→Lh(Lホット）→L+ 緑→Re(Rアース）→RG(R-) 青→Le(Lアース）→LG(L-) ピンの出し方は様々：1979年のJISの解説文では針を下にしてピン側から見た時...

A lot has been already posted but maybe this clears some things... 1. There is NO channel inverted in records! And I highly not recommend to try this by flipping the Drive +- leads on your Neumann cutting system unless you want to spend $$$ for cutter repair... There is a standard in grooves which ...

Yes, that's the one. Very rarely comes up, though. I only mentioned it because the very fact it exists suggests there must be standard, if only we knew what it was. I think I'll have to try the cartridge manufacturers.

If the drums are panned from the drummers perspective should the bass drum make the speaker go in? LOL - you're right, of course - the issue of polarity in the recording studio opens a far bigger can of worms. I began by saying I knew of no test record that could be used for checking absolute polar...

Going back to LPs, it's beginning to look as if either there's no standard for which channel is inverted or there is a standard but it's not widely known. And yet, cartridge makers seem for the most part to be following a standard - they almost always have the right channel inverted. Inverted from ...

the fact is, the absolute polarity of recorded material both on CD and LP is all over the place We have no idea what was being listened to when it was recorded. If it looks like it's reverse polarity to you but that is what the production team was listening to is it wrong? With multitrack recording...

I agree that, in practice, it may not matter very much, if at all. Although some people say they can hear inverted polarity, the fact is, the absolute polarity of recorded material both on CD and LP is all over the place - it's very common, for example, to find the CD of a piece of music has the opp...

It seems such a simple question but I’ve searched for an answer for a year without success. When cutting a record, which channel has its polarity inverted? The reason I ask is: As far as I know, there is no way on earth for a person with a vinyl playback system to know whether his rig is playing bac...
