Google is your friend there.įull disclosure ~ I am a dealer for Rational Acoustics Smaart 7 and I also sell the RTA-420, although my main line of work is as an audio mixer/ system tech. Don't hesitate to email me if you have any questions. One more thing, an FFT can be a single channel RTA or a dual channel Transfer Function.

They have teamed up with Rational Acoustics to basically offer the Spectrograph, and Transfer Function. There is a Smaart iPhone app that will be available pretty soon offered by Studio 6 Digital. If you want flat and consistent mic to mic above 12KHz you jump to the DPA 4007 or perhaps an ACO Pacific.

plus on the Earthworks M30 which is fairly consistent mic to mic up to about 12KHz. A user that NEEDS a flat response mic will likely drop the $600.

The cost is yet to be determined but will likely end up around $50. Smaart 7 is not limited to 8 mics either, but my preamp still is.Ĭalibration files for individual mics will soon be available IF anyone is interested in making the mic look FLAT to Smaart. Smaart 6 was not limited to 8 mics, but my preamp was. The ones I have measured were matched very closely obviously adding a great deal of cost. Sencore (TerraSonde) offered a matrix switcher with 4 unlabeled mics that are also the same exact mic. I tend to use my ear when EQing in that area regardless of what mic I'm using. In fact they typically have a rise that peaks around 8-10KHz which might lead you to cut a bit in that range. Would you notice when EQing your PA, I doubt it. Would you notice this in a recording? Likely not. Above 5KHz is where they start to wander in response. They are pretty much flat up to about 5KHz (this goes for every mic I've mentioned in the post so far). I currently carry 6 of them for use with Smaart. They are similar in quality to the ECM8000, as is the Audix TR40 (but they do have that coolness factor). They are all pin 3 hot (not that it matters) The RTA-420 is the same mic as the dbx RTA-M and the Apex 220. I just wanted to clear up a few things about the SIA RTA-420 and maybe answer some other questions too. I was rooting around on my friend Google and came across this. I'd definately opt for the best mic you can afford.either way.Dennis that mic looks interesting. but with a 28 band sample that becomes a lot less of an issue if you knew what those specific frequencies were doing. I think, till Dennis pointed to this mic and I don't know enough about it to say if it's better.that the Audix TR40 was the least expensive mic I would consider for use with an FFT type measurement system like SMAART. then that negates the auto EQ in that region, and your top end becomes brighter than the flat response you requested. above 3k.the other caveat was that there was not a spec sheet and or that the published frequency plot was a 1 off and not duplicated from unit to unit.Now I realize that only the better mics are going to be lab tested and verified (which if you were going to really try and make critical measurements, should be a prerequisite) but if there was say a 10% reduction in the response above 2k. Everything I've read is that the mic tested ok~by those the PSW but the low end response was questionable, as well as the higher frequencies.
