Qestion About Microphone db I Need Answers Too Quick.

i have a AKG C414B Mic and it has -6 db -12 db 16- db on the back side of the mic.

since the mic picks up everything if i have it on - 6 db and turn my preamp high will it pick up everything like if it was 0 db or just make the vocals coming from mic to the preamp loud?

if i have it on 0 db you will hear stuff going on outside (cars passing). if i have it on - 6db you rarely hear it.

if i turn mic gain high will it make the mic goto 0 db and pick up everything?


hope you guys understand what im trying to say.

    The pad on the mic is too prevent the preamp (sometimes called a buffer amp) built into the microphone body from overloading and distorting.

    It essentially has nothing to do with how sensitive the mic is with regards to noise floor or background noises.

    Strictly speaking the best signal to noise ratio will be with the pad at "0". That's because the signal to noise ratio is concerned with electronic noise introduced in the preamp I mentioned above.

    Practically speaking you can use any setting that pleases you. The 414 is a very quiet mic.

    Just know that if you are NOT overloading the mic that using the pad is the same as turning down the input on your microphone preamp a similar amount.

    In either case it will not change the ratio of featured sound to background noise... you may sense the illusion that it does but I suggest that if you do it's just a change in overall level rather than a change in ratio.

    best regards,
    mike

    Think of it this way: the pad is for when you're putting the mic an inch in front of a guitar cab or sticking it inside a bass drum. For most anything else, leave the pad out.


    All else is in doubt, so this is the truth I cling to.
