    Are B&O speaker mains polarity sensitive?

    Reply Contact
    I'm rewiring alot of my living room and am having to modify and add to some of the custom installed AC power cables for BL3s, BL2 and BL7.4.

    All of the previous installers AC cable has no markings on the sheath as to Positive and Negative (+/-).  Before I start splicing and testing the cables it dawned on me that the speakers may not care if the polarity is reversed.  If they are polarity sensitive can I assume that they are well protected in the event of a switch and would simply not turn on?
        These are US speakers but I would think the power supply would be similar to UK spec in this regard.

    There is no polarity on AC cables... A mean Alternative, as the polarity changes 50 times per second/60 times in the US.

    me again... in the US, the power is 110 volts, 220 in europe, this could cause a big problem if they are not multi voltage.

    They all seem to have only two pin connectors at the speaker end so polarity cannot be important. In the UK, the wires are colour coded so brown is live and blue neutral so I follow the convention. Probably not necessary though!
