Does my theory FAIL or does it work?

why would i listen to a test tone to set shit for music? //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

What happens when you listen to a different song //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif//content.invisioncic.com/y282845/emoticons/scared.gif.f134e57c6c93ccd0f15aa5ac32c7d4a0.gif

I do have time alingment =) Also have auto TA and EQ,a processor that measures car enviroment via microphone,then calculates and sets entire settings as he thinks is the best.

I will do that on one custom field,and on the other i will make manual adjusments after that gonna compare the 2 and see where i am.

Its true though.. The more options u have the more confused u r ^^

Speaking about test tones.. Its recorded at 0db,so what happens when i listen to music recorded in -3 db?

maybe im crazy but i just paly it by ear, when i put a different song i turn it down and use my volume as my gain, and when i hear any sign of clipping i back it down 2 clicks,, or until i feel like its good,,,, never had a problem,,, in my life

It's 3db's quieter. I'd recommend setting it to a -3db tone. Most music doesn't go over a -3db limit.

Also, you can try it then. You're talking to someone who hates the sound of a live concert, I love going to them, but I'm not going to listen to a recording of a live concert over a studio recording. The difference is pretty astounding. And trying to imitate it is not the best idea in my opinion - but each to his own. If you prefer it, go for it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I'd keep it at least one notch below the max volume at least, though, because it boosts the higher ranges.

You can't always hear it clipping, however. Maybe you've never had a problem, but eh, it can always happen. It depends on the setup.

I am gonna stick with the 0db test tone.

Than by theory i can make some adjustment in the EQ or those BBE settings and still be in the clear becouse the song was at lets say -3db..

Right?

EDIT: I dont really mean i want it to sound like a real concert.. I was more thinking about.. When i hear sounds of waves,sounds of nature in the song i get the feeling like i am really there..

Here are two examples of the kind of music i like to listen

Not exactly what he's meaning :/
He's thinking that setting an equalizer and both boosting and cutting at points is the proper way to set an EQ. And as such, if this was correct, setting it after the gains is inappropriate. That's his theory there - nothing to actually do with the boosted signals themselves.

However, it's incorrect based on that boosting a signal in the EQ for any means is not good.

Also, nauc, you can't always hear clipping. You can hear distortion, but frequently you have some sort of clipping before you can actually hear it. Especially in lower frequencies.

i can, God gave me ears like his

An equalizer is not meant to Beef your system up in a specific frequency band.

Its made to "equalize" your system, making it so that your frequency response is as flat as possible.

Setting your gains flat with a test tone gives you the maximum parameters you should operate the amp at.

If you are leaving your amp operating at that level you are endangering it anyway under daily use conditions.

Amps aren't just boxes that either work or do not. They are a pieces of electronic equiptment which have a life based on the % they are ulitized.

You should be using the DMM method for setting gains to find the maximum gain setting you can use on an amp and mark it "MAX GAIN."

After this tune it down by ear or whatever sophisticated equiptment you choose untill it stages relatively well with the rest of your system. Equalizers should be used to "trim" or fine tune your amps output, not to "BOOST" or heavily adjust output.

A good rule of thumb is: "if you have to use more than half of an equalizer band's capability, you have ****ed up something in your installation and are now compromising your electronics to achieve sound quality." which is both incorrect and unnecessary.

Music is dynamic, no matter what RMS it's recorded @ (-20 dB or -3 dB) it can & does have peaks near or @ 0 dB (clipping). So 0 dB tones are recommended to insure the transient peaks in the music aren't clipped. A -3 dB recording is awful, as it only has 3 dB of dynamic range before it runs out of room/clips. Take Metallicas last album for example..it has a track (or 2 IIRC) recorded @ around -3 dB //content.invisioncic.com/y282845/emoticons/sick.gif.b1847c8dabbfeeddbcf1a78052249e10.gif

Thanks for yours answers people.

Now here goes another ''theory'' ^^

Lets say we have a couple of mids that can handle 100 rms

And we have a amp that has 2x150 rms

But we use DMM equation to use only 50 rms from the amp

After that,if we put the loud ON,and boost up EQ,make a couple of crapy boost will the signal clip?

Remember we are using only a third of amps power,and the half of power that the speakers can handle with ease?

FAIL or approved?

Sure it can. It only requires 3dB of boost to demand twice the output from an amp. Boosted signal = more voltage to the amp.. meaning the DMM reading you had prior to boosting has also boosted. Again, this is why it's recommended to cut rather than boost, as gains should need readjusting after boosting.

Everyone that thinks you *have* to set a gain to a certain level is either uninformed or stupid.

Why do they have to be uniformed? you mean like cops? or doctors?
