Hi Guys,

Am i wrong in thinking that Meyer Sound has a program that shows you the throw and coverage of their speakers?  and will tell you the angles of which to rig your line array to?

What is this program called?

Hi Guys,

Meyer has MAPP Online and MAPP stand-alone.  Neither will tell you what angles to use (at least as of last year) but instead display the coverage of the system and interactions between system elements and venue boundaries; the display can be in wide (octave or such) or narrow spectral bands.  You can place virtual measurement microphones in the sound field and compare the magnitude and predicted phase response (virtual SIMM).  You "build" the array, set inter-box angles and push the "predict" button to get the results.  If you don't like what you see, you make bumper angle, trim height, and inter-box angle changes until you do (or realize that you're using the wrong product or not enough boxes).  It's an iterative process.

MAPP is a powerful tool, but you still have to the work.

Prediction programs show you the RESULT of what you put into the model.

You have to have an idea of how the system works-basic acoustic theory etc in order to determine what to put into the model-where to put it and where to aim it.

Then the software shows the result of that.

The same with any measurement system.  It shows you the result of your actions-but does not tell you what to do to cause a particular action.

Such as seeing a notch in the response.   It does nto directly tell you whether or not you can simply eq that notch out.  You have to use other tools to see if the notch is a result of a reflection-multiple drivers covering the same area-or something you can eq.

There is a lot of the "human element" in both prediction and measurement.

thanks. this is what i was looking for.  i knew there was trial and error involved with it in some way.. i just couldnt remember what the program was that lets you see the throw and what not after plugging in the trim, room depth, etc.

This site wouldn't be as useful if we deleted every thread when the question got answered.

hey

As said, most programs work in that you enter the details of your hangs and speakers, and the program predicts what the outcome will be. You adjust and predict again until you're happy.

The only one that works in the "reverse" way is for Martin Audio MLA.  With that one, you tell it what coverage you would like and it works back, trying thousands of different simulations with different splay angles, DSP settings etc for you until it finds the best one to match your needs.

The new EAW Anya uses a similar technology at least in the cabinet, I'm not sure if they're prediction software will also work in the "reverse" way.

I believe the Meyer MAPP is online only. You need an internet connection for it to work. All the data you put into it gets sent to Meyers' servers and then it sends the info back to you.

EAW Resolution software, and prior generation software has been doing it this way for years, you define the venue, how many boxes you have, constraints of where you can put the speaker array vertically, and it will figure out the ideal configuration for the line array depending on whether you weight things for spectral consistency or sheer output power.  Not just for Anya (which is a pretty cool product BTW).

The version I'm using right now says "MAPP Online Pro - Standalone [filename.xml]"  Perhaps Meyer uses the word "standalone" to differentiate it from another form of distribution.

So does mine right on the desk top, but if you try to make a prediction without an internet connection it won't do anything and give you an error message. "Server not found"

Ideal for those instances when you're in the middle of load in with the riggers standing around looking for direction and the PM just said " oh, yea that beam isn't load rated after all so you'll have to hang your arrays 18 ft downstage from the drawing and take em out another 10 ft.     Thats when you'll wish you used Vertecs.

i'm using 8 boxes per side of meyer m'elodie..

You missed the point of his reply.

The Meyer software is online only. LAC II that JBL uses doesn't require an internet connection to see whats happening with the software.

Every other software that I have come across doesn't require an internet connection....D&B, LAC, EAW, Outline.....

It is no problem to run at least the Java version of MAPP "offline", it will let you design your array and show resulting pickpoints, loads, etc. As already mentioned all the predictions are done on their server, so without internet connection there is no "coloured picture".
On the opposite side the time needed to calculate a prediction in all the other manufacturers solutions in a similar resolution as MAPP does still is excessive on "common" laptops.
