Hi
I have tested with stereo sub and now it follows the balance from preamp left/right. You have to have both XLR cables from low output DBXPA+ to amplifier wheather you are using monosub or stereosub.
That's it.
I still don't understand what the meaning of using dualmono or stereolinked GEQ in wizard setup????????
Totally useless as I see it.
Gadget, please explain this technical error.
Thanks
Stereo Linked means any changes made to the left side will automatically be made to the right side...Dual Mono allows you to EQ the left side independently from the right side.
Hi
Thanks for the input, then it is not totally useless after all.
Dennis.....
Can you explain why in mono sub low output from DBX is still showing on the meters left and right.
Is the label on the low output saying left/mono wrong??

I don't know but as long as both left and right sub outputs are outputting a summed mono signal, what is the down side? It seems like it could be convenient for certain live setups with amp racks on both sides of the stage that are fed with separate wiring looms. I don't own a DRPA+ so I guess I'm not the best guy to ask.
Mctwins, you have a way of making this very hard to understand...
1. With a 2x5 setup in the wizard and feeding both the left low and right low to the Mac 5000...
a. Do you have output on both sub speakers...
b. If you unpulg the RIGHT input to the 5000 what happens
c. Plug the right channel back in and unplug the LEFT input to the 5000...what happens now?
If you feed a guitar into the mixer and pan it hard left, and put a bass in the mixer on another channel and pan it hard right ...does just one instrument come out of the left low out or both?
You have to remember... were here with nothing to go on other than your writing...and this:
I have tested with stereo sub and now it follows the balance from preamp left/right. You have to have both XLR cables from low output DBXPA+ to amplifier wheather you are using monosub or stereosub.
is full of ambiguity...so be very specific...

This is only for low out in DBX. Mid and high is OK.
MA-5000 is in dual mode(stereo)
Setup is on DBX 2x5(monosub)
From preamp(mixer) L/R output to DBX input L/R
Leftout DBX to channel1 amp to left sub.
Rightout DBX to channel2 amp to right sub.
I disconnect the XLR on channel1 on amp, left sub dead.
I disconnect the XLR on channel2 on amp, right sub dead.
Meters on DBX is showing signal on low outputs L/R
Hope this helps.
In manual says, use left/mono out from DBX when use mono sub???? as it is labeled on back
of the DBX.
As for auto level it does not perform it for low outputs on DBX
Answers for Gadget
a. Yes
b. Sub dead, the other sub OK
c. Sub dead, the other sub OK
I still don't have the answer to your basic question but you have stated that you are running your MA-5000 in stereo mode and even if the DRPA did send mono sub signal out of left only, it would only hit the left side of your amp until you switched the amp to parallel mode (or equivalent). Stereo mode will always require input signal on both left and right ins.
I have stated that when I use mono sub on DBX
it still make output on both channels on DBX. What I use on Amp is irrelevant.
What I want is when I use mono sub it should only showing output on left channel on DBX, But It wont.
If I could I would use Y-link on channel one input on my amp.
Thats the problem, now I gonna have me some beer. Continue tomorrow
But we still don't know if it's mono summed or not...the left could well be mono summed and the right could still be L/R with out the test to determine if it is actually summed or not .. on both channels we will not know.
If you feed a guitar into the mixer and pan it hard left, and put a bass in the mixer on another channel and pan it hard right ...does just one instrument come out of the left low out or both?
Dennis has already said that if it IS mono summed to both channels then just use one and call it good, but determine if it DOES sum them. I will try it with my DRPA+ tonight.. I don't know how much time I'll have... but we'll see..good luck and enjoy the beer!

I have never noticed (looked) if the L&R low output LEDs light. But, I can confirm on a DRPA, that for mono (summed) lows that left AND right receive and output the summed signal.

That is what I want to know. The manual and the label on LOW leftout on PA+ indicate that it is only the left that is active and gonna be used when running in mono. It seems that it is summed to both L and R. I just want to get this claryfied.
When I pan the balance to left on my preamp I still have signal comming out from both channels from low out on DBX. Same thing when I pan to the right.
When I use Sub stereo on DBX and do pan on preamp L the signal follows left out and R signal is zero. When I pan to the right the L signal is zero and R signal OK.
Prevoius setting (before the subs) I had 2x4 setting and used lows and highs the mid was not showing any signal comming out from the mid output.
That is what I was expecting when using mono sub, that the right out schould not be activated. Then I whould run only left out to my amp and on amp using y-link and connect to channel 1 input. That would tell me for sure that it is pure mono comming from DBX.
So for know I assume that the L and R on low out is summed and for know it is connected left out to Channel1 on amp and right out to channel2 on amp and amp is in dual mode (Stereo).
You don't need a guitar.. or bass..that was an example of two very identifiable sources without too much extraneous noise.
Now...it could be a man talking in the left channel and a woman talking in the right on the tops, with 2 identifiable sources it would be easy to determine if they were subs then we would KNOW if they were summed in the left only...or in both.
I didn't have any time @ the venue to see if mine does that too.. I'm running mono FOH 1x2 and one monitor send from the right mid out.

Hi
Please ask Mike why it dont do auto-level for the low output??
Play "Freebird" (or whatever) in a channel and pan only to the left. Play "Black Dog" (or whatever) in a channel and pan only to the right. Run the low filter up to "out" (full range). Connect some full range speaker (one to each low output (L & R). Listen. One song per speaker...not summed. Two songs in each speaker....summed.
But again, my experience is that both L&R lows are summed. I guess DBX assumed that a person would only want to run a single line to a rack of amps, so only "described" the left output as mono lows.
When using a DriveRack PA or PA+ and creating a program with a mono summed low output (for a mono sub), both low outputs will pass a mono summed signal. The DriveRack PX is the exception. It only passes signal out of the left low output when such a configuration is configured.
As for the Auto leveler, I just tested this. when using a mono sub configuration the PA+ will NOT attempt to balance the low outputs. If it does, you likely have a stereo sub output configuration and not a mono sub output configuration.
Then it doesn't matter if the amp is configured in dual mode(stereo). It still gonna send monosignal from the dbx to respectivly channel on the amp.
Do I get this right???
But what happens if I choose mono input and GEQ monodual. Do I connect the cables on the dbx on left/mono input and left/mono low output to get fully mono signal, and what about the rest of the mid/high outputs??

To get a dual mono setup you need to choose STEREO then DUAL MONO in the wizard...
both outputs put out the same summed mono signal when a mono sub is configured.
Yes (as compare to dual).
But to use both sides of the amp for subs you have to connect to each low output of the DRPA -- or -- add a jumper wire on the back of the amp. Personally I'd use the "parallel" feature if the amp has one.

Ok guys, I think I got the picture now. Nevertheless, I will do some more test, but right now, my time is limited.
Last question???
Is it ok to have my amplifier in stereo mode?
Thanks

Thanks everyone for your feedback and help. Everything is settled and works perfectly.
Here is a freq response with the new JBL4641 subs.
This is without any autolevel, GEQ. Only small adjustemnts on PEQ.
You can also follow the link I posted before there is some new pictures added with subs.
Thanks
