Turbosound Flashline

Re: Turbosound Flashline

Hi Peter,

Although it is a 'Beta' version - the acoustical data is already checked and correct, so I'm happy for you to publish any screenshots you like.
The reason for giving you and Steve access is to try and keep this as impartial as possible, so please feel free to discuss any aspect of the system. I feel this would be a little more in the spirit of the forum community than being posted by a manufacturer.

Bennett, In answer to your shading question - it is possible to change the gain and filter (HF boost) setting on each box in the array individually in the software. These filters are overlays of real measurements from the amplifier to keep the prediction as accurate as possible.

Chris,

Speaking for both myself and Bennett (as we hashed out the techniques together) we need to be able to account broadband for delay and the magnitude/phase of the range of classic biquad filters on a per zone, or per-box, basis to get the most out of our line array implementations.

Without this ability were are forced to pick a box of equivalent height from a competitor whose LA prediction software allows looking at predictions with the additional filter sets.

Please feel free to PM me about this, and we can talk offline.

Very cool, Peter. Now if only the frequency response wasn't on a 25dB/division scale!!!

Is the heat plot a bird's eye view? I assume it can do the other meaningful plane as well, I like to look at my lobes.

Don’t you just love how flat and smooth that looks :D~:-D~:grin: I squashed every thing up so I could fit more information on the screen shot (normally you don’t do that), and then the microphone legend covered up the HF roll off I wanted to show you ….so 25 dB it was. ... ie this in about 1 inch of screen height.

You can of course set the scale to what ever you like including auto.

The “heat plot” as you call it is the plan view; you can of course do an elevation. You can for example have a left & right - Flashline with Flex as out fill (or any box that you have the GLL file for) and look at them individually or combined. You can move a microphone anywhere around the field and see the respective frequency response change as you move the mic – it’s a really good piece of software.

Well, let me start by apologizing for lobbing the "this PA will do 120 db at 400 ft" bomb and then running off. As I said, I got that info from a print out of an Ease file a friend sent me.
Dom and Chris sent me the beta version of the Flashline Ease files but I got bogged down in a major proposal that was due yesterday. Today I finally got to play around with the Flashline beta in Ease2. I created a scenario that is typical of my work environment, such as a Stageline SL320 in a parking lot somewhere - or as we call it, a gig in a field. I asked the PA to reach 350 feet, which is probably a bit further than i usually need to throw, but not out of the question for my work place. Best trim height I can squeeze out of a SL320 is about 28 feet. So, I hung 12 Flashline aside in that situation and ran 1/3 octave slices at the highest resolution EASE will do. (It took my MacBook Pro running EASE under VM Fusion almost an hour to grind this resolution out!) I did not run any plots on the subs. So, here is what I came up with. I hope it clears the air some. I am told the Flashline file will go public and be available on Turbosound's website very soon, so anyone who wishes will be able to put it through it's paces.

Re: Turbosound Flashline

Hi Steve,
Just to add to your stuff – here is another view – 10 boxes to about 350 ft. It’s a high resolution plot, and it took forever to process. I have never seen 150dB on the auto scale before. I also have to apologize, this week has been the busiest week of the year for us - things are going really well since we purchased the Flex Array.
Note – I would also expect that some Flex would be used for the near field under the Flashline, in which case I would have modified the angle on the bottom few boxes and things would have looked even better …
@Phil – I have processed and shaded this array with Turbo’s presets. I expect it’s similarly to what you are thinking of doing?

Peter

Re: Turbosound Flashline

Hi all,

Remembering the limitations outlined earlier in the discussions between EASE focus 2 and EASE there are a couple of things you can do.

In options in EASE Focus 2 you can select 'extended mode' in this mode you are able to add EQ filters globally or on individual hangs. In terms of Focus 2, it won't show you phase, since given it's specs it is not relevant in this instance. The EQ is global on a cluster so is essentially input EQ which would have an associated group delay but would not effect the clusters dispersions properties, in terms of multiple sources as outlined above EASE focus does not account phase data between hangs therefore the integration in this software is not needed.

Of course if purchased, full EASE and speaker lab will allow filters within clusters which do account for phase and thus enable all the steering you wish. As per the beginning of the thread, if you have the time for the modelling at this level of details (seems impractical on tour - hence the free focus 2 for touring), we highly recommend you purchase ease.

Hope this clears things up

Dom
