test tone help please

[blackbonnie 5,000+ posts]

i have downloaded the winrar program or whatever it is called, but im not sure on what tones to download. i went to the sticky and tried to download the link to all the -3db tones, but it just takes me to the home page, and i cannot find them anywhere. i know realm of excursion has a bunch of tones but im not sure what to download. can someone give me some help on what to download. i am looking at the -3db tones. if someone has a bunch of them grouped together that i could download all at once, that would be great. if not what do i need to download, to set everything, including speakers and filters. thank you

i can make them for ya right now if you want...

for speakers i suggest -3db 1khz

for subs i suggest -6db 50hz

 

[blackbonnie 5,000+ posts]

that would be perfect, basically i need everything. but that will help me out tremendously. do you know what people usually use to set their subsonic, and LPF's?

50 hz -6db

320 kbps

with a -6 db tone do you turn the hu up 6 more notches? (for example my hu maxes out at, clips at 23 with 0 db: set with 0 db 50 hz 22/30, -6 db 50 hz 28/30?

lpf is usually set by ear. your suppose to lower it until it blends nicely with your front stage. problem is, most people have inadequate front stages, so between 60-80hz is generally used. you dont really need test tones for that.

and subsonic filters, well i dont really use it cause there is almost no music that plays that low anyways, but if you want to be safe put it around 10hz under what your box is tuned to. a lot of times, ssf arent even needed because no one really makes songs with freq in the mid 20's that might hurt your sub. hell a lot of times you get a big impedance rise when you go far below tuning, meaning your sub wont get enough power to bottom out anyways

nope. if your HU clips at 23, then it clips at 23. thats the HU signal. has nothing to do with the amps. the idea behind finding out when a HU clips, is to keep that clipped signal from ever going to the amps in the first place.

for example, if your HU clips @ 23. leave it on 23, pop the -6db test tone in, set gains accordingly, call it a day.

k, thanks and what if the gain is maxed when i use the -6 tone? cuz it's half way now with the 0 db 50 hz one

it really doesnt matter where your gain is, because its all related to your headunit. if your headunit has say 2 volt preouts, your gain is going to need to be set much higher than say an eclipse hu with 8v preouts. as long as you do the math right, set your gain properly, youll be ok in the end. there are too many variables to say every gain will be set to xx position.

what voltage are your preouts? and whats your max volume? if your max volume is say 35 and you clip at 23, even if you running say a 4v preout deck, you wont reach 4 volts till 35. so if you clip at 23 and set your gain using that volume, your gain will have to be set even higher to compensate. not sure if that makes sense. for example, those 4 volt preouts might only give out 1.3v @ volume 23

so what are the advantages of using a -6 db tone for my subs, rather then a -3 db test tone?

my preouts are 2.2 volts, max volume is 30 on the hu and with a 1 khz 0 db tone i reach 2.2 volts at 30, same with a 50 hz 0 db and 60 hz 0 db tone so it makes sense that the gain will prolly be close to max cuz it goes from 6 volts to .2 and on volume 22 it read 0.2 so i should be fine then?

most bass is usually recorded @ levels under -6db. basically all your doing is getting more power out of your amp, without clipping.

for example, lets say song A has three bass notes. 35hz, 40hz, and 45hz

35hz is recorded @ -7

40hz is recorded @ -10

and 45hz is recorded @ -6

this means that the 45hz tone will max out yoru amplifier, without ever clipping. now if you used a 0db or a -3db test tone to set your gain. your missing out on extra power that is not being used up, because you used to high of a tone. does that make sense?

if your only reading .2 volts @ volume 22, that would answer the question of why your gains need to be set so high. youll be alright

if you wanna be extra safe you CAN use -3db, but its just not my personal preference.

it makes sense, thank you. is there any place online or so, that has a write up on this stuff. that goes in depth? im just looking for something that i can read over or relate to if i have problems.
