John,

- Will there ever be a way ( & are you able to create a soft-patch within future releases of REW ) to use these new USB based microphones in conjunction with, REW's option to "Use loopback as a timing reference" ?

Thanks <> EarlK
Hi John

Has there been any progress on this?

Re: MiniDSP UMIK-1 Microphone

I'm interested in buying this mic. Since it runs on usb power alone, what is the maximum extension I can add considering it's rather short. Is it usb 1.0 or 2.0? thx

Re: MiniDSP UMIK-1 Microphone

Hi, I've bought nine (9) UMIK-1 and now I'm downloading the calibration files from the miniDSP site.

ALL, I rewrite, ALL the nine (9) files are the same calibration file. What changes is ONLY the serial number

It seems to me that "All UMIK-1 are calibrated with a unique calibration file" is a *wrong* statement "as minimum" and I don't want to write here what I am thinking...

What do you think of this behavior?

Add: from #700-2572 to #700-2684 the files are identical, equal, the same...

Have you contacted MiniDSP to see what they say?

Re: MiniDSP UMIK-1 Microphone

Hi

Can I use the HDMI output from the laptop to TV (Panasonic Viera) and then use the SPDIF from the TV to Dac/Preamp (pre/pro)? Don't have HDMI inputs on my pre/pro.
Thanks.

My first reaction was "what the hell are they doing?" Man...the forum software has some interesting word substitutions.

Second thought was since they're manufactured one right after the other in an assembly line, then maybe they would measure identically. Its not like you took 9 mikes all made at different times.

The proof would be to compare their response and see if there is any material difference.

Re: MiniDSP UMIK-1 Microphone

I've bought nine UMIK-1 from Cross-Spectrum.
I have nine different calibration files (from CS). All the mics are different.

There are more than one hundred UMIK-1 without the "individual calibration file" from MiniDSP, those who bought these microphones are using a wrong file and they are getting wrong measures.

The problem is that they don't know anything about this issue.

P.S. Anyone can verify this just change XXX with a number between 572 and 684

You will get columns that are perfectly identical

If you still have any of the original 9 mics ( from CSL ) you could create your own ad-hoc calibrations ( by comparing acoustic results of good to bad & then changing "the bad calibration to match the good " / until the acoustic results match . This process will be somewhat tedious & time consuming , but it is still one way ( that is better than a "kick-in-the-pants", IMHO ) .

Re; the hundred users with so-called bad calibrations // one way to view that , is just how much of a placebo effect this whole question of calibration has actually become ( ie; it doesn't really matter since ones ears still end up being the final arbiter // at least for those of us who trust our ears ) .
