    I got a refurbished Marantz SR 6014. It was all positive values.
    I've now changed it to reflect negative values with a max level of zero, so that nobody can turn the volume up past reference.
    Good thing too, since I find him really comfortable listening at about negative 15

    Well, it depends.
    If the material you are listening to is 10db below the 0db mark (this is not the volume, but the waveform itself in the digital file) You can safely run your AV at +10db.
    Amplifiers don't have volume control. They just get voltage X (from the dac) and put out voltage Y which is amplified. Clipping is done when the input voltage is soo high that the output can't amplify that much and just "clips" the top and bottom of the signal. You can have clipping in the DAC itself too. DACs also have a maximum voltage they can operate at.
    You can have a song or a movie mixed at 20db under the clipping point. So turning the AV from 0db to +10db won't result in clipping, because the input V is low.
    Example. Watch TENET at -10db. Then switch to a Disney movie. You will hear that the Disney movie is too quiet, compared to TENET. Well TENET is mixed to the clipping point, while almost all Disney movies are mixed 5 to 10db below the clipping point.
    So final answer is "Yes" you can damage speakers if you turn it above 0db. (positives db values), but also "No" because it depends on material.
    Bonus:
    i actually used an oscilloscope to check on my denon AVR where does the LFE signal clips.
    I played a 40hz sine wave at -3db (because audacity clips for some reason if you play it at 0.
    My sub trim was at 0db.
    I turned the volume slowly to +12db, and observed the sine wave.
    I think i was getting above 2 volts of signal and the signal was perfect, no clipping at all. I couldn't actually make the signal clip.
    But my amplifier can take no more than 0.75v of input voltage. So even if i can have a clean AF LFE at +12db, the DAC inside the subwoofer amplifier will clip.

    Have the volume set at 0db with nothing playing, change it over to read positive. Remember what the volume number changes to and just never go above that. The numbers reading backwards just seems weird to me🤷🏼.

  • @Joshmedo
    @Joshmedo 3 роки тому

    TIP: Some receivers allow you to limit your max level, for ease for non AV people to use in your household I would just determine the number level associated with 0dB and set that as the max numbered level the receiver is allowed to reach therefore not being able to turn it up passed reference level. Thanks for the info :)

    Reference is 115 decibels. When watching a movie if you’re volume is set at “-10” then you should be at a PEAK of 105 decibels of loudness.
    Usual dialogue is much lower than this. But an explosion would be really loud for effect of the movie. It’s based on the movies sound mixer guy. Notice when you listen to music at the same number of volume it’s much louder. Music is generally “pushed” to the peak. Assuming your receiver can actually power the speakers to a reference loudness. It may not have enough wattage.

    Found a better explanation in my opinion:
    "Think of 0 dB as maximum volume. For example, if your receiver reads “-25 dB” it means that the volume of the signal has been attenuated by 25 dB (that is, made 25 dB quieter than the loudest it could possibly be) before being output to your speakers."
    It do not need to be more complicated than that.

    Another great video which prompts a subscription and one more newby question. I used the calibration microphone when setting up my new Klipsch/Jamo 5.0 system. It automatically put individual speaker volumes as follows: the Klipsch loudspeakers at a negative volume (-4) and the Jamo center speaker at +6 and the Jamo wall sides at the maximum +10. I thought this would be hard on the receiver so I reduced the volume of each speaker by 5dB. The overall volume is low for normal listening at -40dB and loud at -20dB with speakers set lower individually. Are these good volume settings for my receiver so it doesn’t fry prematurely? Thanks again!

    • @tommygunzz7586
      @tommygunzz7586 3 роки тому +2

      Relative scale (half empty) vs absolute scale (half full). It’s just a way of looking at it. Just know, that when you engage the speaker level test tone it’s going to adjust the receiver volume to reference. Make sure all individual speaker Channels are turned down to flat before you calibrate each speaker using your spl meter. The key is just knowing the volume number that represents the peak level. So if 80 is the reference number chosen by your receiver once the test tone engages then, I don’t turn your receiver up past that point. Playing anything at the 75db or 80db range will probably result in hearing loss anyway.
