I am planning on splitting up my system to have speakers for certain jobs. Our party and school dance system is going to consist of four dual 15's. and four 18" subs. That is my large system and only for large stuff obviously.
I have all the amps racked and sat down last night ot try to tune up the sound. i am using a P v electronic crossover. It seems that the sub output is getting full range signal all the time.
I know it is because when i turn up the 10k slider on the EQ it boosts the signal. I figured it would gove me a sub output only? What the heck?

Secondly, I got frustrated because when I tried to tune up a different setup. Full range single 15's with ("midranges, horn, and woofer)
those with a set of subd sounded awful. I just couldn't seem to get it to sound good.
I didn't have the power adaptor for the second crossover, so I was just running it through the 15ch eq.

Does anybody have a good method for getting that "sweet sound" out of a system. I'm not new to the EQ concept but I haven't been that good in tuning it up. It can be done better for sure.
I am not one that likes super bass heavy music, but it's gotta hit a little. And I have never had the old smiley face on the EQ, so I know a little, just anybody have any suggestions?

just lost all my eq points tonight, using drpa you need an active crossover, to get at what you listening for. i know now i just kill all the full freq. your idea freq for subs should be from 20hz to 250hz anything after that you start mid range then hi range.
100hz give you that boom so does 63hz so don't over do it there, as they the music gods and goddess would say it to sound muddy well good luck, hope this helps
The answer is in the way you hook it all up with the EQ. The terminology used here is bi-amping i.e. having seperate amps and configs for different speaker types. Basically you shouldn't be using a full range EQ to provide signal for tops and subs on the same amp - it doesn't work.

You have to have a seperate active sub crossover at a fixed frequency fed to the amp then to the subs. Second is to use your existing EQ with seperate amp for the high range speakers only use the EQ to tweak/fix your tops.

You use the same level output from your mixer to both your top end and low end systems. If you've got the equipment try this config, it sould sound much better.

Cheers.

ROQ out.
Zhem, I'm not sure if I read that right, did I just see you need an active crossover for the DriveRack PA? It's early in the morning I'm just checking. . . the DRPA is by far one of the BEST units out there, it is a crossover, eq, limiter/compressor, Analyzer, Sub Synth etc. . .

As for your subs getting the full range frequency, do me a favor, first pull the eq out of the chain entirely, run the mixer - crossover - amps. . . it may be where you have the eq in the chain that's causing full sound to "escape" and make it's way into the sub.

But another little thing, if you are using dual 15" tops, why take all the "balls" and low end out of them, use the crossover to run the subs, and send a full range signal to your tops. You really won't need to eq the sub, so what you would do is send your Master output to your eq, into your mains amp. Then send from a Sub or Booth output, to your crossover to sub amp, to sub. Just give it a shot, different configurations work for different applications
DJ Nexus the first thing I must ask is if you know how to use or setup your cross over (x-over) properly??

If the answer is yes then I dont see why you cant figure out what is wrong in the system yourself. You dont have many components.

Im guessing this EQ of yours is before the cross over. To keep it simple your system should be running like this:

MIXER ==> EQ ==> X-OVER ==> AMP ==> SPEAKER


Now without knowing the model x-over you are using there can be a few things wrong.

1- cable that goes to bass amp is plugged into the wrong output from the x-over.

2- you have not set your x-over frequencies correctly. I think someone posted some settings you could start with earlier in the post.

3- you have the x-over slected for the wrong configuration (if it has this feature). EX. 2way,3way,4way,5way.

4- x-over could be malfunctioning.

For your other question....There could be a lot of things that would explain why you wont get that "sweet" sound. Too many things to list. Glad you dont have that old smiley face Smiler

If you tell me exactly what you have down to the T then we can start from there. Or Private message me if you would like.

Hope this was of some help.
On the main system I'm trying to clean up...
1. The mixer only has main outputs, no seperate sub outs.
I am taking the full range outs and into one side on the eq. That then goes to the amp for the dual 15's. I donlt push bass that hard through those, but they do get the full range sound.

2.The other out is going straight to the x-over, I had it first through the other side of the eq for seperat full ranges I was running, but I skipped the eq and went to the x-over.

It made no difference.

the front of the x-over has 3 knobs. a low level, high level, and gain.
in the back there is one set of ins, and two sets of out. One marked high pass and the other low pass.
the low pass gets mostly full range sound though? that's where the holdup is. I have found the other adaptor for the other x-over and I'll try that tonight, It is like any other, and has filters and stuff. Anyway i am pretty sure I know exactly what to do to that one to get it to work.


I think the problem is the p v crossover, It seemed super simple and easy to use and it came with a lot of concert stuff i bought recently, it just seems like it isn't up to par.

And the part I was really curious on is, how do you tune it up? I know a song will sound good in a certain configuration, but how can u tell if it'd sound better with a notch more of 1k? or maybe it needs a little 63 to push it? Anybody have a systematical method for sound checking?
ok i see what could be the problem here..

number 1 going from the mixer you should then go to the graphic eq then from the graphic to the electronic crossover.. the one i use is this:



VSX� II
Item # 00461480
MSRP: $359.99

this unit has a sub out and works very well and will serve you without problems..

this is how you wire it.. from the mixer to the graphic eq,,, then to the unit listed above and then to the appropriate input for the mids/highs on the top box... thru an amp that is mid powered... then from the sub out to the higher wattage amp.. then to the speakers... if i had specifics on what you have then i could give specifics back... for futher information check my website... www.geocities.com/thatsoundman
