Umik 1 Vs umik 2

So does cross-spectrum UMIK-1 have any disadvantage compared to ordinary UMIK-1? It will only be used on DIRAC (perhaps REW) with the new Pioneer or Marantz receiver.

I have one more question. I read somewhere that the UMIK1 cross-spectrum cannot be used as an acoustic sound level meter. Whereas the regular UMIK1 does. There is some truth to that.
 
Well then. How do I measure sound pressure with UMIK1 with AVR/Dirac? Without a sound level meter, of course.

Doesn't seem like there's an SPL meter function built into Dirac.
In their Umik-1+ Dirac guide, they only talk about relative levels:
 
OK. I just have a dilemma. Some here on the forum claim that UMIK1 is batch calibrated and Cross spectrum individually. Others claim that both are individually calibrated. So I don't know what is true. The difference is about €30...
 
@ivo.f.doma Factory calibration vs CSL calibration:

Keep in mind the sample size of 1.
 
Thank you for the information. What does this mean for me? I'm waiting for a new AVR, preferably a Pioneer 705/905, and I want to buy a good calibration microphone for the Dirac PC application.
 
I guess the difference is Umik 2 is high res, so more expensiv.
 
I am a total beginner, so yeah.
Both products will be sold in parallel, I asked.
 
I have a USB-C umik-1 and it's great for measuring room acoustics, where the frequency sweeps etc can be played at a loud level. I am sure it's more than adequate in that regard.

That being said, for the price difference it could be worth paying more for the lower noise floor of the umik-2. I also use my measurement mics for assessment of low level background noise, and found the noise floor of the umik-1 to be a limiting factor. I have never tried the umik-2, but minidsp seems to have nailed the space for economical measurement mics that perform well.

I ended up using a uPrecisionMic from Studio Six Digital, which is a lot more expensive but has a very low noise floor and a ruler flat frequency response with good omnidirectionality. It's also a USB mic with built-in pre-amp & ADC (like the umiks). With this mic, very low level sounds can be recorded and played back with negligible noise. The umik-1 is much noisier in this kind of application. I'm not suggesting you get a uPrecisionMic, but it's an example of a use case where the umik-1 might be limiting.

The Studio Six Digital measurement mics (they have a couple) also have analog output jacks, which can be convenient for running audio i/o from a smartphone etc (but for value, and if you don't need this, the umik-1 can't be beat). If you'll only be doing room frequency sweeps, and budget is an issue, the umik-1 is great. As is noted above, the smaller umik-1 capsule gives better omnidirectionality than umik-2.

Sorry for going on about the Studio Six Digital stuff - I have no affiliation, but like their hardware and software. It's way overkill for room measurements. I have this stuff and still use the umik-1 for room measurements.

CSL increased the price of Umik-2 from $200 to $215. That's not good.

You’ll see that most products have increased prices and quite substantially at that. CSL is no exception.
