| Determine speaker power wires polarity |

If it is the common CEE 7/16 Alternative II "Europlug" (Type C), then --- Quote ---Because it is unpolarised, it can be inserted in either direction into a socket, so line and neutral are connected arbitrarily. Ref: https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets#CEE_7/16_Alternative_II_%22Europlug%22_(Type_C) --- End quote --- The fact that it happens to be powering speakers is irrelevant to the discussion if you are talking only about the power mains cord/plug. That is what caused confusion at the beginning of this discussion. |

jotwerde, Please attach the image, rather than using a hosting site. I was at work on my coffee when I saw this and the site was blocked by the firewall, so I didn't respond. Yes, the polarity of the mains is unimportant. It's AC and goes through a bridge rectifier, resulting in DC of the correct polarity. |

I don't like using attachments, using a hosting site and embedding the image is cleaner (at least when done right). Thanks for mentioning the bridge rectifier. Very insightful. |

Attach the image, as usual, post it, click the attachment's thumbnail to open the image, copy the image location (the procedure for this, depends on what browser you're using), edit the post and paste the image's URL into the post between [img] tags.
