Experiment with clipping

[Decipha 10+ year member]

always set the gain with a 0db tone... you'll never have a problem with clipping unless the source material (song itself) is clipping

where can i get 0db tones from

****ING BULLSHIT...... i just did a 50hz 0db test tone, i played it and the voltage jumped even higher than the -6db. it hit 50v on the dmm thats like 2500W clip

WTFFFFFFFFFFFFFFFFFFFFFFFFF??????????????????????????????

Then you're doing somthing wrong

Make sure the Intell Q option is turned all the way down. It's by the SSF.

no shit.. a 0db tone is louder... your gain needs to be turned down

you need to get your hands on an o-scope so you can see what's going on, something doesn't sound right.

Your voltage is staying constant, right?

And by SSF I mean HPF... I bet you have it turned up...

are your speakers disconnected?

 

[mustbenu 10+ year member]

my HPF is turned off so therefore there is no intelliQ setting on...

yes the speakers were disconnected... i tried it with them connected and discconnected, i dont think it matters i got te same voltage both ways.

MAYBE my Headunit is a piece of shit and is throwing clipped signals over 50% volume? could that be possible? for now im look for a nice AC VOLT guage that i can keep up front with me when i drive so i can watch for clipping and maybe buy the remote gain adjuster too.

......well IT IS a JVC ive learned not to expect much from those brands..... not that its saying much unless its an eclipse or an alpine i dont even consider it going it my car.... thats just MO

is there any autometer type guages that read ac voltage?

get an oscope and 0dB tones, find out where your HU preouts clip. Start with the front, then rear/mid, then sub. Make sure they all clip @ the same time. Also, lots of todays music is already recorded well pst the clipping range.

Now work your way through all of your proccessing the same way. Then @ the amp. Set your gains with -10dB tone for a 3:1 gain overlap. (step 4 of the JL tutorial mentions gain overlap)

We use the 3:1 ratio because of the way our music is recorded. Songs aren't recorded @ 0dB throughout, there are peaks - where music could clip, but only for a thousandth of a second which really isn't even audibly unless you listen to your music @ full blast, and there valleys in between. The 3:1 gives you more AVERAGE power for music. Most SQ competitors use this method

maybe ill just sell everything then i wont have to worry about this shit //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
