  • 2x 48v to a stereo mic (damaged?)

    Posted by Adriano Castaldini on August 11, 2017 at 2:44 am

    Hi everybody,
    I’m afraid of having damaged a mic…

    I’ve bought the Audio-Techina BP4025 mic that’s a stereo X/Y mic with a 5pin-to-2x3pin cable. I connected the mic to the stereo-recorder with the two 3pin-XLR (Left and Right channels) and I gave 48v phantom to BOTH the channels (so the mic itself received 2x 48v). Later I discovered that giving the 48v just to one single channel (i.e. left) was enough to power both the channels as well.
    So arrived my doubt: Is it possible that I have damaged the mic giving 48v to BOTH channel? Or not?

    Thanks a lot.

    Extremely unlikely. Audio-Technica’s document mentions no prohibition about powering only one side. Did you actually experience any problem with the mic after providing phantom power to both the Left and Right outputs?

    I own (or have used) stereo microphones from 4 or 5 different manufacturers (including Audio-Technica) and I always provide phantom power on BOTH sides. In fact mixers (or recorders) which provide individually switchable phantom power per channel are rather in the minority.

    In the consumer or pro-sumer world global phantom power is the norm. Once you get into the professional world independent phantom is the standard.

    Sincerely I didn’t hear something particular after having powered both the channel. I simply noticed a “noticeable” difference between the sensibility of one capsule on the other (i.e. when 48v was on both cha., right capsule captured a bit louder than left capsule).
