This is by no means a lab test but just me messing around with some cool gear đÄźquipment: Smaart V8 ISEMcon EMX7150 MOTU 4pre Fulcrum Acoustic CS121 passive cardioid sub woofer DX1595 2 way 15âł coax Powersoft X8 patience (not really). Green trace onax front Blue trace 90Âș ofax.ÄȘfter that i also had the DX1595 do itâs thing along with the sub woofers. Green trace onax front Blue trace 90Âș ofax. However, Smaart Di v2 is provided here, giving you an environment with all the control parameters. away from the subâs centre i spaced the 2 subs with +/- 1.5 mt. between them. Without Smaart, TRACT can be used as an eight-band equalizer. away from the subâs centre with no spacing between the 2 subs. Green trace onax front Blue trace 90Âș ofax.ÄȘfter the second measurement with the mic 90Âș ofax at 2.8 mt. Green trace onax front Blue trace 180Âș ofax.ÄȘfter the first measurement i placed the 180Âș mic at the 90Âș ofax side again at 2.8 mt. away from the centre of the right sub woofer (for no special reason).ÄŻront vs back spacing none (as close together as possible). Not that i do not trust those spec sheets but just to know what will happen in a real live set-up. Me being a âtechnicianâ means i always want to verify whatâs in a spec sheet. The CS121 is a passive cardioid design so no 2nd subwoofer needed to create reduction at the back of the array. The rig is over at our practice space I'll have a chance to dig in again tonight.Finally i found time to play around with the Fulcrum Acoustic CS121 and a DX1595. I'm sure in the time/money balance, it would end up being far more costly than just buying Smaart, but it could be an interesting project. I'm trying to talk myself out of the notion of attempting to 'roll-my-own' dual FFT in Matlab - it's supposedly capable of real-time analysis, though I haven't explored that capability yet. I took Bob McCarthy's SIM class a few years ago, and have some of experience driving SIM3, though mostly in a controlled 'lab'-like environment.
While I've certainly still got a lot to learn, dual-channel FFT measurements aren't completely new to me. Since we generally mix ourselves from stage, and setup is often space- and time-constrained, I don't expect to do much in-situ at present. Finally i found time to play around with the Fulcrum Acoustic CS121 and a DX1595. I'd simply like to measure our system's response in controlled conditions and create an EQ preset in the mixer based on something more precise than my ears. Face Ă face technique entre : Lexus LC Cabriolet 500 V8 et Smart 1 Pro+. I wouldn't say there's a particular 'problem' I'm trying to solve. Thanks Frank I'll look into ARTA as well. The documentation is a labor of love and a great learning tool, too, IMO. If your goal is to learn your way around discrete Fourier transform (DFT) based measurements, ARTA is an excellent, low cost start. You explicitly set the window on the impulse response before calculating the frequency response, for example, so you know exactly what you're getting. I see ARTA as more of a precision lab tool. Because of the "live" transfer function display, Smaart is great for experimenting and getting a feel for the effect of changes in the measurement environment.
#SMAART V8 VS SMAART DI PORTABLE#
No doubt Smaart is easier to use in a portable live sound setting where you're trying to verify system health and time align subs under time pressure. I use them both and the results compare well.
#SMAART V8 VS SMAART DI LICENSE#
A personal use license is only ~$120.ÄȘRTA is not equivalent to Smaart but is a very nice set of tools and allows you to make many of the same kinds of measurements. As Bennett said, it would be useful to know what problem you're trying to solve, but you may want to have a look at ARTA in any case.
