    Hi,

    When turning on phantom power, it seems that it needs time (a few seconds) to build up the voltage to full. Basically mic is low output then immediately goes to full output after a few seconds. And when disengaging, the power doesn’t fully dissipate, it takes time for phantom power to die down fully.

    Is this normal?

    Thanks
    Don

    That’s normal on many mixers and condenser microphones.

    Best practice for condenser mic is no fader raised when engaging phantom power.
    AS for every other mic, plugin it, engage 48v if needed, then only set you gain.
    You can also engage MUTE.

    Cool thanks. It’s just my first experience seeing this behavior on a mixer.

    And also yea, I normally have the fader down or muted when setting phantom power; I was just paying attention to the metering while I was adding gain slowly, and then it went to red immediately.

    A lot of the time it’s the mic stabilizing after it gets powered up. On powering off
    the mixer may have supply caps on the phantom circuit for the channel and they will fade
    off still powering the mic for a bit.
