-10 db test tones

[zachzchw 5,000+ posts]

I remember reading a thread mentioning that its a good idea to use -10 db test tones.....

I believe the reason was that music is dynamic, and if you use 0 db tones, you might not get your full unclipped potential out of your amps.

So, anyone have any -10 db tones? Or know where to make them, where the -10 db rating will be accurate?

Check there.

If you wanna spend money, A2K has some discs that will have them on there. Check http://www.davidnavone.com

you can generate your own test tones at what ever db level you want with the room eq wizard very nice tool here is a link http://www.hometheatershack.com/roomeq/

How do you save the audio files?

I see export but known for what i made.

Thanks in advance.

Sorry to thread jack, but is it really better to use this test tone rather than using the 0 db test tone?

-10db test tones will be really quiet compared to 0db tones. This causes you to set your gains way too high at the proper voltage reading, and will cause huge clipping issues, overheating, etc. Many times, you won't even be able to reach the desired voltage level with gains turned all the way up.

So I have to call BS, and recommend you not listen to whoever told you this. 0db test tones FTW.

For 0 db tones.

Idiot. That is all.

At least jmac offered a reason that one might use -10db tones. You just flamed me. Wow, I'm imressed with the size of your E-Penis.

You spread false info. You deserve a simple flame. You have been slapped in the mangina.

Have a nice day.

You deserve it IMO, what will it take to get you stupid people to stop spreading false information? If you dont know what you're talking about, just dont post, its easy.

some of the best known people in the autosound industry say otherwise
Also -10dB tones is a USACi SQ technique:up2somet:

----a 3:1 gain overlap will rarely result in "hard clipping" with music material----thats why it is not audible---the facts are that if the gains are set for 1:1 with typical music material the most amount of AVERAGE POWER you can achieve is about 10% of the amps rated power----this means that the 100 watt amp would only deliver about 10 average watts to the speakers-----will that protect them?----you bet it will-----just like keeping a Ferrari in first gear----but does that seem reasonable?-------a reasonable overlap will allow use of a lot more of the amps power and takes advantage of our inability to hear the effect of short term events...........RC

Thanks guys for the contributions. And let's not forget that we don't record our music CDs at AHB (All High Bits) for every bit of the music. There are quiet passages, average passages, and places where all 16 bits are high (i.e. max loud). Likewise, we don't listen to our music at full volume all the time. (Well, most of us don't, eh?)

Well, the only part of my original post that is probably inaccurate is when I called BS. Most mainstream hobbyists would probably be better off using 0db test tones. But as has been so eloquently explained, there is a legitimate use for -10db tones.

I apoligize for my ignorant post, and hope none of you gurus have dreams about offing my dumb arse. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'll still stick to my personal system of using 0db tones.
