send me a test tone

[atlbraves]

Can anyone send me a test tone for 50hz my cd player isnt a mp3 player so cant have it in mp3format either. I downloaded some of ROE and the 50hz tone is reading way too high for what it is. I set it at 57.4 when i set it at that its not loud at all. When i set it by ear to what sounds good and test it it reads over 90volts so somethings wrong.

If anyone can upload a 50hz test tone for me to set gains let me know. If you need a email to send it to let me know I will pm you my email.

thanks

Tones will always be much louder than music tracks, unless you get -db tones

the issue is that you are setting with a 0db tone and then playing music that is -3, -6 and even lower.

I set with heavy bass music and other set with more negative db tones, but any way you do it, a 0db tone will only be good if the setup will be used for playing 0db tones

well yea i am using 50hz 0db test tone and its reading way higher than the voltage i want but it sounds good on music. I want to make sure i aint sending a clipped signal to my subs and trying to set it so i can send 1650rms @2ohms to the pair of subs.

I listen to rap most of the time so what test tone should i use

most music is at least -3db's.. and alot is probaly more around -6... but i'd still wouldnt go higher than -3 to be safe

Yeah, I never use a DMM for this anymore because of this factor.

you could use a song like "white girl" to check the gain level. just don't run any test tones at full volume once you get it set up.

ok so try a -3db test tone to see if that helps at all

You could also do this (I ***** this from a past thread I had a while back):

The 1.41 multiplier is representative of the square root of 2, which is in turn the calculated equivalent to a 3 DB increase.

So if you use a -3 test tone, you would use the 1.41 multiplier, if using a 0 DB test tone, you would use 2.82 as your multiplier.

I REALLY think this is much more accurate than just setting a max volume level, throwing a 0 DB tone at it and then setting the gain.

I assume with most of you, as with me, when you listen to music you don't want to have to turn up the volume to max level you set your gains at to get your fullfillment of bass. And when you set the gain at a high volume level using a test tone that you most likely never see, you restrict your max amperage at a much lower volume level hence having to turn up the volume to the level you set your gains at.

Use a 0dB tone and double the voltage. Or a -3dB tone and multiply the voltage by 1.41

dam I set mine with a 0db, maybe its time to set it with a -3dB haha

This is why I set mine a year ago with bass heavy music. I chose the heaviest bass song I knew of, and set the gain with it. I have had no issues, and i don't have to turn everything all the way up. I have also recommended this for others with great success.

ok my amp is a zx1500 rated for 1664 so i figure to set it at 1650rms so with a 0db i should set it around 114volts that would be 1650rms@2ohms=57.4x2

or just double the wattage saying instead of 1650x2=3300 just double that to 6600=81.2 volts

well i set using a few hard hitting songs like juice box, dreamgirl, you aint know, and put on. Seems about right. I hooked a dmm and 50hz 0db test tone and its reading around 93volts so either i am clipping the hell out of the subs or that test tone method is just way off. Not sure

Friday i am gonna be in lakeland and stopping by mobeious house and hes gonna get me all set up running right. He built the box for me and is a great builder so if u need a box contact him

regardless, you should always be gauging it based on your senses of where it should be. Set it where it seems right by ear/eye, and then play it for a few days with your regular music as always

if the subs seem to be stressed or are heating up/getting smelly, turn it down a bit and see how that does, if you feel like its got more in it and the subs are under no stress, turn it up a little and see if it gets louder sustainably, and so on

I no longer set using a dmm, you're better off just getting to know your equipment and knowing its limits than trusting the false sense of security a dmm can give you

i dont know how you're getting your numbers but 1650 @ 2 ohms = 57.4v
