I am intrested what does the ''RANGE'' and ''FRONT END DEFEAT'' buttons mean,and how should they be pressed when i am setting gains?

This is a MB Quart RAA2400 amp,i am going bridged to power single MB Quart RWE 352 15'' sub.. Sub is declared @700wrms,and the amp @800wrms @4ohms bridged.. On 2 ohms it has about 1200,but thats another story..

 
Yeah.. Front end defeat.. And there is the ''RANGE x1 or x10'' whats that all about..

BUMP for answers //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
front end defeat bypasses gain and crossover controls

range button converts filters to variable from 500 to 5,000 Hz

IE: 1x will be 50 -500 HZ

10X will be 500-5000HZ

You can see this info on the picture you posted. the lines i added connect the area you are effecting. changing the range will effect the freq that the freq dial effects

you would set this depending on the speakers you are connecting.

 
Now lets say.. I want to set gain for my (single) SUBWOOFER! I turn ON filter,set it to LPF, range X1, and about 80 khz,and that means that the sub wont be playing tones higher than 80 hz?

Another question: my HU is pioneer deh p 88rs,should i still turn on filters on my amp's when i am going to turn them on my HU also? I mean on the amp i cant get perfect precision.. On the HU i just set that the sub doesnt go higher thatn 80hz, that the mids dont go lower than 80hz,and i dont really know the settings for the tweeters..

yes on the first question. that is correct.

i dont know for sure on the second question. I have always only used the head unit. with that said however i have never heard any difference what so ever when using both at the same time. becasue of that i'm not so sure it matters much either way. i have always used just the head unit becasue it is much more tunable with my parametric EQ then using the amp itself

 
Yeah,i thought so 2.. So acctualy the smartest thing to do is turn filters off on both amps (Subwoofer amp,and components amp)

What about the gain settings? For the components i am buying Alpine Spr 17s,i have a amp that is 2x180,and the speakers are declared @110wrms.. Am going to set HPF at 80hz,and usings the ''gain'' formula with DMM am going to set the gain to give about 120wrms,it will have power in reserve which means cleaner signal,better sound if i am correct,so that is not a problem..

But what about setting gains on the sub? First of all i know i have to bridge it..Ok that's easy,plus from one minus from other chanel its all writen down on the picture.. But what after that? Should i set gain with DMM or how? I know that setting SUBWOOFER gain by listening is very difficult even for pros,and this is my FIRST setup i dont have a clue.. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif Osciloscope i dont have,and dont know ANYBODY that has it,i mean hey-i live in Serbia lol..

As u see my amp has CLIPING LIGHTS,i guess that they are there to ''lower the signal'' when it (signal) begins to clip..

So i ask u,what is the best way to set gain for my sub?

http://ampguts.realmofexcursion.com/MB_Quart_RAA2400/ this is the amp i know.. We all know that MB Quart is RF's little sister,at least it was.. As for the woofer i wrote it up,but i'll write it again the model is MB QUART RWE 352 2+2ohm 700wrms 15''subwoofer..

 
HEEEEEEY I FORGOT TO ASK //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

When i am setting gains.. This FRONT END DEFEAT ''thingy'' should that be OFF or ON?
