andrew, i'm getting an 01v96v2 and I can't wait to try this with the band... Should be interesting!
Thank you for your time in developing it!

This may sound a bit silly, but I would like to know how we can tell if a certain bass driver or midbass driver is suitable for horn loading, some say to look at the B/L factor, is this correct? how can we be sure based on T/S parameter, for example i heard alot of people said that the popular JBL 2242 or 2241 18" bass driver will be horrible in a horn-loaded enclosure while a Precision Device 1850 is good for horn loading, what specific should we look at?
Thanks!!

s.
saw the coolest thing ive seen in a while. a company called aderra was recording the show and selling USB wristbands of the show as soon as it ended. i know how the duplication goes...but was wondering if anyone has any idea of the technique they use for these? i saw 2 room mics placed about 10ft in the air in front of the board...and they ran into a portabrace bag where i assume the recorder was. any ideas?

Hi Brian. O.A.R. and long time FOH guy Jef Powell record ProTools every show direct from the Digidesign Venue, but the live recordings for the wristbands are simply a L&R mix blended w/ 2 audience mics onstage and the pair you saw at FOH and sent to a record output AES.
They have since upgraded from the Aderra system to a custom (very slick) combined recorder AND duplicator that Jef has patented. The fans can get the wristbands within 2 minutes of the last note. If you thought it was cool before you should see it now!

owen..
thanks for the info. the idea is SLICK any way you look at it. its such a great idea. wish they had this technology at a few shows ive been to in the past.
i like the technology and after first attending that specific concert and then hearing a demo of the same show on the website..i really liked the way it came out.
im always trying new ideas with live recordings and i think i might give this one a shot.
thanks for the info!

I tried switching out one element of the signal chain each time it has happened. I haven't thought of troubleshooting with some of the suggestions posted here, and am in the process of doing so.

Yes, I did a side-by-side with a 935 and a 945 - to me the 935 was modeled after the Beta58, it seemed to have the same charactoristics and mid-rangy thing going on. The 945 seemed to sound like "a Beta87 if it was a dynamic" and had fantastic GBF.
Everytime a vocalist brings their own mic (usually a B58) I reccomend they try my 945's first - and they never switch back 
Sorry if it sounds vague, but that's the best way I can describe it before my morning coffee.....
compare them for yourself and tell us what you think!

Langston-
First: I also got one of these in and immediately had problems because when my PC detected the new hardware (the USB codec) it did not automatically change to this in the sound card. I had to manually change this in "Sounds and Audio Devices" within the Control Panel. Now it automatically switches back & forth, depending on whether I have the codec plugged in or not.
I just mention the above to save you from the aggravation I went through.
Second: If you can, I would like to see what you measure on a 70V ldspkr and at the various taps.
Third: I would like to know your other varied impressions of this product once you have put it through its paces. If you can compare the measurements from this system to those from another reliable system, that would also be great.
We can communicate publicly or privately.
Thanks

The impedance test function in Smaart 5 is really not anything more than the transfer function display graticule set to display ohms rather than level. If you read the " how to " for the impedance test I believe you'll find that Smaart is simply measuring the voltage drop across a known resistance ( and thus the current flowing through it ) at various frequencies. If you were to take a transfer function using the same measurement set up as used for Smaart 5 with Smaart 6 or Foo or similar program and run a calibration curve on say three known and suitable ( ie: 4, 8 & say 32 ohm ) resistors I think you'll be in business. You would be interpolating the results of course but it would give you a very readable impedance graph.

I hear there was an impedance test in version 5 of SMAART, but I have a Mac and 5 won't run on my machine.
Any recommendations for an accurate plug and play impedance test unit?

Langston,
That looks like a good product.
Looks like these test units (as Riley points out) are simply measuring the voltage drop across a known resistance ( and thus the current flowing through it ) at various frequencies.
So the method I’m using should get the same results, just slower. Considering the time and money (and potential for aggravation as Tom points out) it would take to get Boot Camp and this program going, for the amount of crossover building I do, I think I’ll probably stick to the two resistor method, since I am already pretty much done with the passive crossover rebuild now.

It is undoubtedly your meter. Cheaper rms voltage meters are typically only accurate around 60hz. 20 yrs ago when I couldn't afford any decent test gear I was doing exactly what you describe and ran into the same issue.
I use LMS to measure impedances now, but I know my Fluke 189 is reasonable flat to 20k and I also have a old HP millivolt meter which works great for wide band audio range voltage measurements.

You don't have to spend very much time on muso forums to realize that a lot of folks have equipment that's way outside "what is necessary" for the purpose at hand. Is a $6000 Driskill guitar or $10,000 TwoRock amplifier necessary to play Honky Tonk Woman? Nope, but there's a lot of folks out there who will do this. Or chase down some $20,000 vintage Strat and a $40,000 Dumble amp. Custom bubinga Pork Pie drums. Don't even think about a quiver of vintage Selmer saxophones. To folks like this, it's all about playing the best and/or trying to get the best sound. ROI has nothing to do with it. So it's not terribly surprising that someone would want to put a D&B or Nexo rig in a bar to play Gimme Two Steps through.

The OP sounds like he has a good idea about what he wants to do and that he has the budget to pull it off.
In the case of a PA system, I think there is actually a reason for getting something that might be very very expensive. A d&b Q-rig is going to give you SPL that no other system I know of is capable of for the footprint (without sounding like crap) and footprint seems to be a key priority in this case.
Also, on the amp-draw front (which I forgot in my previous post) the Q-system is very light. I run my two D12 amps on one 230V phase with an amp-meter in my distribution box and when playing full throttle it doesn't even draw 2A - which would mean less than 4A on 110V.
