Purchase Driverack PA or PX?

Posts: 4
I am a newbie to this forum. Don't see specifc subject for PX. Read lots about the PA. My question is a little complicated. I want to buy a Driverack PA or PX. I can pick up either for about the same price. Apprx. $350-399, since the PA seems to be selling for a bit less since it is (and has been) more mass produced.
Anyway, I have (2) Bose L1 Classic sound systems that I am running as a L and R conventional PA system from a Mackie 1402VLZ Mixer. These have there own pre-amps and remote mixers, which also invits lots of problems. Yet, I have managed to get them to sound pretty nice. I just have lots of feeback problems. I have tried a Behringer EQ6200 w/ feedback contrl, but it is a bit of a joke, not to mention JUNK, and talk about noisy!!
I am now considering the DBX PA or PX. Since the Bose will be acting, essentially, as powered speakers, do you think the PX is a good choice, or since the PA is available for the same $ (or even less on E-Bay), what about it ?? Is either of these a good choice for my setup?
I have been runnig the main outs to a Mackie SRS1500 powered Sub, where I engage the High Pass outs to the Bose L1s, which have no bass modules attached (poor-mans sub). THis sends on the Mids and Highs to the the L1s.
Given also that my backup PA is (2) Mackie SRM450s (powered), do you think I should get a PX or the PA? Again, the PA is actually about $50 less.
One more question: do I need the mic that comes with the PX?
Thanks so much! Humbley......SingCommercialDave.

I would run the subs and the L1's strait out of the Driverack. Hi outs to l1's and low outs (mono left low outs to the sub and cross with the Driverack, rather than the sub... I wonder what propagation delay would be on the L1.. ? For alignment purposes.
Beware... there has been banter @ the PSW (quite a bit from the pros) that the L1's response(hi frequencies) falls off dramatically after a number of months of operation...If you like I can find the link, but they were also talking about a delay factor when using subs...this could be the killer here since the DRPA and PX don't have much delay available...The 260 however would be the perfect tool...more denaro though...
One further caution... not all Driverack dealers on EBAY are authorized. Some sell units with out serial #'s and without warranty cards... make sure the realer is and AUTHORIZED seller or you will have NO warranty...

Also, I can't find a \"Authorzed Dealer Locator\" on the DBX website. Do you know how I can check them out?
THNX again.
The cross over point would be interesting to predict.
Because the L1's wouldn't go very low. (Difficult to find info on net)
Maybe 120hz. What do you think??
The design to the L1 would cause feedback problems. Bose 802 have similar problems. (I own a pair and love them)
The driveracks feedback elimination is very good.
Some state that the DRPA has a small amount of noise. I personally think it is quiet.
5 cents worth from down under
PS couldn’t find info on “Behringer EQ6200� Do you have a link?

Sorry I quoted the wrong Behringer. It's the FBQ6200. Here's tHe link:
http://behringer.com/FBQ6200/index.cfm?lang=ENG.
Note, in my setup the Mackie SRS1500 Subs X-over is at 120Hz. The L1s then get everything above it, which works fine. Volume adjustments to the sub can be made from the Subwoofer level knob.
Lots of high end. Seems full spectrum with the sub, yet, like I said, ithe L1s give lots of feedback.
The DRPA or the PX is far better at eliminating feedback that the Behringer. By a long shot.
Mark
Also I need the angular duality of the causial angle with regard to the immediate primary lobe of the left sticks relationship to the sub woofer...
Sorry... just having fun with you ... Actually the first line would be helpful in all the detail you can give...I'm off to do one of my favorite bands... The Loose Cannons! should be a fun rockin night!
Be well

Check (call) Full Compass for some good pricing on any of the Driveracks (260 included). Don't go by the \"online\" price. It will be higher than the phone price.

Also under the \"search\" dongle on the blue bar above you can type in JBL EON and you will find a number of recent threads on the Eon speaker setups...
Gadget
Well with the words JBL EON I found this...
http://www.dbxpro.com/forum/viewtopic.p ... ht=jbl+eon

and this is in the FAQ's section...

As for the limiter setting ...proper setup is a difficult thing to get right... too much and too early it will squash the sound and limit the output, too little and you stand a good chance of damaging your speakers. The limiter setting is different for every speaker and every amp combination, and is exacerbated by the powered speakers that don't allow for proper gain structure. The process is tied to the gain structure and knowing exactly where each piece of equipment clips. Difficult at best with the powered speakers. Another thing that makes it difficult is that no one can seem to agree on how much headroom you should have in the system, and many run the ragged edge ALL THE TIME because they are under powered.. or don't have the equipment to do what they do properly..or they just don't know any better...You also DON\"T have any control over the limiter in your EON's, or ability to turn it on or off... so you'd be stacking limiters which I don't like ...
I'm sorry your frustrated but this new digital technology offers a lot of tools and a steep learning curve. All the answers are here for most of your questions, you just have to dig a little...We are all volunteers here and in the summer especially, don't have a lot of free time.. with that in mind I created the FAQ/READ ME FIRST sections... it's all pertinent, and you will learn something in each section that may come in handy in the future if nothing else.. I have for instance included Dra's Limiter setup in this section:
http://www.dbxpro.com/forum/viewtopic.php?t=959
Which includes gain structure and setup info...
So we don't mind answering questions that have a \"cut and dried answer\" (There's another one for you brother Mark) ... but ones that have no real good answer ... hard to answer cogently...
As far as the \"mic\" thing I assume you are talking about auto EQ? read these:

I thought that the JBL presets would balance all this out. Again I thank you for your work and help but there is nothing in the links that you sent that will help me detenine the following:
Which Eq responce to pick (A thur D / Low , Medium, High) or what is the difference.
I am pretty sure that for my use I would set the AFS to all LIVE. But the sensitivity to what Medium??? I guess.
Subharmonic(%/Hz) , Bandpass, Compressor/Limiter(over easy/threshold/ratio/gain)), GEQ/PEQ ????? I have no idea.
I bought this piece to protect my speakers and it seems that if i don't set this right it will harm them. And the more I read the more confussed and frustrated I get. Maybe the excitement turned to frustration is not allowing me to comprehend this clearly?
Tell us what system that you want to set up.
List speakers and amps used. (no, you can't use both the 15 and the 10 at the same time. At least for what you are asking us to do with the PX.)
DRA
Again, I understand how to set up the rack I just don't understand what to set the settings to.
Any extra information will GREATLY be appreciated.
DRA
There are no amps because the speakers and the sub are \"self-powered\" or active.
DRA
do I have to change anything?
If you have, ten I get your ready. The only other thing that you may want to do is flatten the speaker a bit as described in the outdoor out eq method in the READ ME FIRST section.
DRA
If you have, then I guess you're ready.
You didn't answer the question.
DRA
What I was asking about it:
Which Auto EQ responce should I use?
(Flat, Low, Medium or High or A thru D) what's the difference?
Do I leave the AFS to All LIVE? What is the correct Q?
I assume not speech. It's Music Low, Music Medium or Music High?
When I increase the mixer gain are the line volumes supposed to be raised also?
What is the correct High-pass and Bandpass Filter setting?
What is the proper Subharmonic setting?
As far as the Compresser/Limiter how do I find out threshold, gain and ratio?
EQ - GEQ or PEQ?
If the instructions explain this than I apologize I don't get it. If this thing is less complicated than I think and the preset feature does these setting already based on the type of speaker than someone PLEASE tell me.
AFS - How much feedback do you have? Even the speech setting is more narrow than a 1/3 octive EQ. Typically I use Music Med. Since you are a DJ you'll want to go 6/6 or 9/3. Lift at 5 secs.
Lines volumes - don't know what that is
Filters - already set, but I'd set an HPF for the sub at it's -3db point / BW18
Subharmonic - I don't use it. There are no correct settings. You're on your own. Your subs won't handle the \"lower setting\". If you use use the \"upper setting\" only.
Compression - If you're smart you won't use it.
Limiting - Set by the wizard. (I think) But if you want to set yourself... connect 1 Eon and bring up until the eon's limiter goes red. With an overshoot of 2, overeasy at 4. Adjust the PX's limiter threshhold for that output until it puts it out. Repeat for the sub.
PEQ / GEQ - Your only have a pre GEQ and post PEQ. GEQ for TEMPORARY room adjustments. PEQ for PERMANENT speaker adjustments (as described in the RMF section)
DRA
I really appreciate your time. If you know of any sources for me to gain better knowlege I am up for it.
Book learnin' is good (and important), but doin' learnin' is as, if not more, important.
