DR PA PLUS WITH POWERED 2 WAY AND PASSIVE SUBS

abrody

Thanks for all you do for others. I want to run my QSC powered 2 ways on top and some old passive subs below. I will run them in stereo, which wizard can I start with? I am VERY nervous about the right starting configuration. Any help is really appreciated!

Here are the speakers:

Also, I beleive that there was a message for power speakers saying use mic/line? Does this sound familiar?

Thanks!

Dra

Welcome. Which preset? It doesn't matter at all, because you are going to start from scratch and rename it to something that you want. I'd start with #1.

In the set-up wizard you'll select a stereo-linked EQ with custom passive highs and custom subs (stereo) with a custom amp for tops and custom amp for the subs.

Anything else?

Dra:
for the reply. I meant to say that I have active QSC's on top and I run a Crown XLS for my subs, that amp is in the list. Do I simply connect the low out to the amp and to the subs and the highs out to the active speakers?

Will I do any damage by running active speakers on top and powered subs in the bottom? I want to follow the #1 option and booklet and try out the pinking feature and auto eq, etc. Does this make sense?

Where should I cross the subs?

Thanks for helping the newbs...

Dra

I understood your system. You still select the custom amp whether you have active speakers or not. You can select the sub amp but you are going to do your own gain structure set up anyway. Go to the READ ME FIRST section on the main forum page and read the START HERE thread. In there you will find a detail set-up guide. You will, however, set your top speakers amp level to 50%, and not plug them in to the DRPA+, until you have completed the guide. Then you'll balance with the subs as described.

PS - lots of other good stuff in the RMF section.

Dra,

Thanks it worked absolutely perfectly, someone suggested turning on the subharmonic synthesizer, does this seem correct? The pinking was great, i don't remember specifying a crossover, did the DRAplus do that for me?

Again, it was a really easy plug and play set-up and THANKS for your advice. Truly, it was a high stakes gig and I took a chance and it worked well.

Dra

Yes, it did set the x-over. Probably about 100hz, which is good. However, it probably did not set the HPF for the subs (high enough). Go in and set it to about 40-45hz BW18. That will protect the subs from damage due to trying to reproduce freqs that they can't (very well) and freeing up power from the amp.

No, forget the subharmonic synth.

I have not lit up the subharmonic synths, Two very basic questions:

1. When I come back to the venue, I call up my preset settings, do I just go through the menu items again?

2. I have some old 3 ways but 2 amps, interestingly the highs are 16 ohms and the mids are 4 ohms,, while the subs are 8 ohms. What happens when the 16 and 4 is out together.

Help is always appreciated :!:

Dennis

1- Not sure I understood question...A) Return to venue. Recall program by number/name. C) Rock & Roll

2- I know for a fact that I didnt understand that question...

Ya.. I assume here that even though you mention Sub synth... these question have nothing to do with that?

1. When you get to a venue you shouldn't NEED to call up your preset, it should still be there unless you actually change it from show to show, even if you have a preset for each venue you simply call up that preset...just remember that if your last trip to the venue had been set for a full tilt boogie and your starting out with those settings and a semi empty room and at lower volume.. things will sound different...

2. I assume here :roll: that your saying that your running a :Tops" "subs" setup amp wise? And that the tops are "passive" (meaning using internal xovers)??? If so then those issues are dealt with BY said xover...If not then you must be running mono and then you use the active crossover (Driverack) to deal with those issues... so which is it?

Gentlemen:

Sorry to confuse, lets take off the table the subharmonc topic. My question, are there step by step directions for how to porceed when using the stored settings. At the venue, I called up the settings that were there from last time, then I lit up the efx, sub amp, QSC's, etc. There was no sound, should I have gone through the set up menu again? I cant find step by step directions.

The other question is not Drive Rack PA related, I have passive subs, and mids and highs with no active x-overs. What happens when I plug in a 16 ohm speaker and a 4 ohm speaker in to an 8 ohm amp in stereo or 4 ohms mono.

Your help is really appreciated, really i need help with teh recall settings,I got rave reviews first time out and am going back to same venue.

Thanks again,

Alan

I'm betting you didn't SAVE your setup??? It takes 3 presses of the Store button to save a preset/setup... you will need to answer a few questions...where do you want to save this preset?, name the preset..., are you sure you want to overwrite the preset @ this location?..."IF THE STORE LIGHT IS ON (red) you need to save what has been changed for the next time...

Now if you did all that and your SURE you stored the preset... then you need to store a new modified preset, unplug and shut down the DRPA and then plug it back in and make sure the setting are still there and that the system sounds the same as before you unplugged...

As for amps... they aren't typically 4, 8 or even 16 ohm.. the only difference is that as the impedance rises, the power is lower than an amp rated @ a specific impedance...Like Peavey typically rates its stuff @ 4 ohms...but it will work fine (but have less power than @ that rating... here is where you need to do your setup gain structure to take care of those issues... have you read this?

I'm not familiar with a DRPA+ but if it is the same as a 260, on power up it could be fully muted and you have to hit all of the mute buttons. I think you have to go into the utility section to defeat "mute on power up".

Do you mean a raw horn(?) and a raw mid driver parallel into one side of an amp? Still confused. :?

A good system to use with my sports betting? I am looking for a good system to use with my sports betting, please if anyone knows of anything good then let me know. I do not have to much money to spend, probably about $500.

Boy you guys have me REALLY confused here :?: estheri, You have written a very vague post...LOTS more info is needed for any kind of recommendation...what is a "

My guess is that it is a small system for making "announcements" during a "compitition event" between a pair of roosters or a pair of pit bulls.

Dra

Will this be an install or a circuit system? I would lean to one of the many powered speakers that have a mic input on them. Get a cheap wirleless system and velcro the receiver to the top of the cab. Tear down sometimes has to REALLY fast at these "events".
