Web2 jan. 2011 · Put a small amplitude sine signal in on the primary side of the transformer with one channel of the scope connected across the terminals, and put the other channel of the scope across the secondary winding you want to determine the polarity of. The proper position of the transformer "dots" should be apparent from the relative phases of the two ... WebAccidental reversal of speaker wires can happen when the wires are not properly labeled for polarity. This action is known as making the speaker "out of phase," and results in audio oddities. Although this is not dangerous to a speaker or amplifier, proper power delivery and speaker response is not possible with reversed speaker wires.
