    If you don't have an audio interface, and are using headphones, why are you even bothering with the K-System at this point? This is for calibrating near field monitoring systems, not shooting 83db directly into your ears with headphones.

    You can still use the K-System on your Master Buss.

    I'm sure you can, anyone can set the meter to whatever they want. How are you measuring the 83db coming out of the headphones to properly use the K-System as it's intended to? The K-System isn't just watching a meter, its about calibrating volume levels coming out of the monitor speakers.

    It isn't just about monitor calibration either, just like headroom is not the only purpose of it. It's both, and more; because they are interdependent.

    You are setting up one concrete value as a "known", even though it too, can be variable; and working backwards through the signal flow. Your monitors are adjustable probably, your audio interface has a monitor volume, your audio interface's software likely has its own mixer. Your DAW, many more points of measurement. Mixer, Clip Gain/Region Gain, channel strips, etc. And then these people want -14dB also, to maintain headroom.

    All the points inside the box are what it calibrates, against the monitors. Otherwise you could just turn your monitors up or down until they hit the 83 dB SPL you are using as a target. For headphones, they just use pink noise.

    1. Try Windows settings > System > Sounds. If the slider of the system mixer isn't 100 % make it louder.

    2. Use any gain VST plugin as the last (the most lastest, yes) plugin on the master buss. Adjust volume as you want. Just google "gain VST".

    3. Try Equalizer APO: https://equalizerapo.com

    No. K-Sysytem is about "the loudness war", dynamic range and headroom. Calibration to 83 dB doesn't relate to K-System at all.

    When I see you guys talking about this kind of thing I realize how much of a newbie I am.

    Check out this video at about 8 minutes in. There is some guy talking who does not agree with this.

    If you have no clue what you're talking about, you should probably sit this one out.

    that´s exactly how it is.

    and you can still mix wrong with a k14-metering display, just as you can do it right with PPM.

    I saw this: https://gearspace.com/board/mastering-forum/1024714-depth-bob-katz-k-system-tutorial.html
    and used it to calibrate my speakers in my room. "Now I am mixing with speakers".

    I have a doubt: If I have calibrated my speakers, should I use the k system on every track too? I mean, Do I have to lower every volume to -14 db ? (for example).

    "I USED THAT TUTORIAL LINKED ABOVE"

    I calibrated my speakers to have a 65 dBC { That's for my room, detected with spl meter on iphone [<40m3 = 74 dBC] -> minus 3 dBC (because of the perceived additional loudness of the room I had calculated with a track example and the pink noise) -> 71 dBC (famous target of -20 reference) -> minus 6 dBC (to get -14 reference) = 65dBC }

    now i got my speakers calibrated.
    The total volume doesn't sound so loud when i listen to a track at 0db.
    Also I don't know if i have to downwards every track volume to get my 0 point (k-14)
    I tried, and the volume feels to low, is that how it has to be?

    THANKS

    Sounds all very complicated.
    Glad I do not have to do any of this. :yes:

    Just no!
    1. LUFS is ITU-R BS.1770 compliant, which means K-filters are used!
    2. The K-System metering contains neither filters nor gating.
      It's a simple meter scaling offset for dBFS Peak and RMS in combination with monitor loudness calibration.
