L.F. musc advice!!!!!

[mad4car]

yeah tuners, i'm installing a small system for my daily driver....

some stuff what i have so far is:

stinger 240amp alternator
pioneer DVD deck(3 sets 4vlts out)
4 channel dd
earthquake mono
2 eight inch eminece
2 selenium d405 driver
4 bullet tweeters
1 15" rockford fosgate T1
earthquake 2.5 cap
earhquake 7 band preamp

I'm thinking about buying a DQXS and i need advice:
1)If i run a audio control dqxs, would it make a big difference to the music?
2)Could i run the preamp between the deck and dqxs so the dqxs can see a higher output voltage because the preamp pushes a better output voltage than the deck?
3)Or should i hook up normal with the preamp and forget the dqxs....

Thanks....

1. Yes running the DQXS would make a difference in the music.

2. If you running the DQXS you dont need the preamp because IIRC the DQXS has a built in line driver.

3. Forget the preamp and just go with the DQXS, its a all in one unit (crossover/EQ/Linedriver) and is very flexable for future upgrades.

^^ Thanks bro...

agreed , imho pelt away d preamp if u get d dqxs

if u think u need line drive is if its a big system with multiple amps or if d amp\s can accept higher input voltage & u rather not use d amp gain but prefer using line drive instead , but generally speaking d voltage out from d dqxs is usually sufficient for most systems ...

[agabriel]

but for a larger system shud u still or cud u still add eg. a matrix before the dqxs to increase the output from da deck. havin a similar issue wit my dqxs and i havin to use gains on da amps if not da volume has to be very high before u can hear anything. assistance needed. 4 amp system 4 10s 4 driver single 15 sub

"a matrix before the dqxs to increase the output from da deck."

how come , why not to put d matrix after d dqxs b4 it enters d amps ? ....

[agabriel]

dat was de suggestion from my installer concernin de volume issue we were havin

[kurpal_v2]

Just wondering, were the amps gain properly matched before deciding the system needed more line drive?

[- Rovin's car audio -]

i might not as versed\experienced in d dqxs as other ppl but to my mine is to process d signal 1st as u want it with d dqxs (or whatever eq\xover) then to "amplify" it with d matrix b4 d amps , thats d way i do my own systems with never any problem but i guess other ppl might have different ways of doing things ...

i have a catalog from d a\c dealer showing different ways to use their various equipment some where in my workshop so i will look for it tomorrow to check back how a\c says to do it ...

[agabriel]

kurpal de gains were min as per audio control instructions.

[nigel1977]

That's because all audiocontrol digital products have an output voltage of 3.5vrms.
because of the the output opamps used. Those devices can only do 3.5vrms.

This was confirmed in a discussion with Tom Walker at SBN.

[agabriel]

right so that being said what is the solution ?? use the gains on the amps to compensate??

[SR]

use the matrix AFTER the dqxs

or use an eqs instead

or get more powerfull amplifiers


according to audio controls owners manual

the dqxs does 7.5 vrms

[mad4car]

well from the advice i seeing here, i 'll buy a matrix also and put it after d dqxs.....Just to be on the safe side!!!!

Thanks...

[- Rovin's car audio -]

d matrix may or may not be needed , like i said d line drive out d dqxs is sufficient for most systems

try d dqxs by itself & if there is still a need for it then buy it later...

[mad4car]

Thanks Rovin...that makes sense....

Having owned the DQXS myself, i'd recommend the matrix after the DQXS option. I found the Equalization Overload indicator would come on quite easily if I tried to get around 5V of output from the unit..

Putting the Matrix after will allow you to run the DQXS well within it's limits AND get very powerful line drive. Those Matrix / Overdrive pre amplifiers are very powerful units, so maximizing amplifier performance with gains set to minimum will be easy..

[mad4car]

Thanks 3stagevtec......Rovin advice makes sense but i'll still buy the matrix just to put my mind at ease, because i want to get the most from the system and i'm sure i'll be upgrading in the near future...

Read it again, it says MAXIMUM output level at 7.5vrms

I'm trying to remember who were the other people standing next to me besides Rave when I asked him about it.

[SR]

i know what it says

but its whats documented by audiocontrol to the public

[nigel1977]

I'll pretend you of all people didnt say that.

[SR]

lol

why so many pieces of audio to add to the chain ...

zapco sxsl 16v balanced line drive and u good to go

totally different class of music quality for money..

Firstly i must say that's a best choice on processor. Can't go wrong with a DQXS.

Reading this has got me thinking and I just have one question, jus to ease my mind before I do it, about my system, similar situation.
My processor is a JBL MS-8 and I've noticed that I do have to raise the gains on the amp a lot more to get almost the same volume than when I was using an EQS (better line drive) which had my gains at minimum.
Now can I add a Matrix after the MS-8 and get good results??

Like so:
Deck > MS-8 > Matrix > Amps

Thanks

[viking1705]

i agree with rovin.Try the DQXS first its easy to add the matrix after if its needed.
