Re: MiniDSP UMIK-1 Microphone

Hi All, new to the forum. I used the PE OmniMic for a bit (borrowed from a friend) and was going to buy one but found this instead. I was shipped yesterday. I have no idea how to use REW so I need to dig into that.

I am looking forward to hearing the answer to sdurani question.

Most laptops I've seen don't have a line out but instead a headpone out. Can that be used to send the REW sweep signal to the receiver/pre-pro or is that output equalized for something like speech intelligibility? The reason I'm asking is because I had read that the line input on a computer is different from a mic input, with the difference being that the latter was equalized for speech (on-line gaming, teleconferencing, etc). Wanted to know if that was the same for line out vs headphone out because I'll be able to connect the UMIK-1 to my laptop via USB for input signal, but only have a headphone jack for output signal. (Trying to retire my M-Audio Mobilepre USB.)
The headphone out should be fine. I've never heard of a headphone out being optimized for anything. The only thing that will influence the headphone out is the quality of the sound card.

Re: MiniDSP UMIK-1 Microphone

No problem, enjoy the mic. If you have any problems just contact miniDSP. I had an issue and they are working with me to get it all sorted out.

Re: MiniDSP UMIK-1 Microphone

I use a USB mic and it works very well with my laptop sound card (which i was able to do a calibration file as well)?

To calibrate my laptops sound card (Vista OS) i had to disengage the effects, then it all worked.
The laptop had a headphone out + mic in.

Also had to change to a single sweep. (for my mic i did).

Adjust the levels in & out (mine is set to 50 mic + 60 speaker (headphone) out.

Re: MiniDSP UMIK-1 Microphone

I received my UMIK a couple of days ago, and whilst it works exactly as advertised with the WIndows version of REW, it seems to have a few issues with the Mac version. Which is a little disappointing as that is why I bought it.

When using it with OS X Lion and my Mac Mini, it defaults to 48K format and I had to change the sample rate to 48K in REW. However, whilst I could make a measurement, there was something drastically wrong with the FR, with a massive roll-off below 1khz.

I replicated this with my Macbook Air.

After some fiddling about, I found that if I switch the sample length in the measurement window from 256K to 128K the FR was as expected and the same as the Windows version.

However, the question is what effect reducing the sample length will have on accuracy?

That aside, the calibrated response seems to be more accurate than my uncalibrated ECM8000, especially at the top.

Fuzzmeasure seemed to be fine.

Here's a pic of the issue with a 256K sample length.

Would you recommend the headphone out over an HDMI connection?

I wouldn't expect any difference, but try both and see if there are any meaningful differences.

Longer sample length gives better signal-to-noise ratio, better immunity from the effects of minor background noise. Using the multiple sweep option is another way to get the same effect.

Edit: I have no explanation for the weird frequency response with the 256K sample length, that is a head scratcher. Have you gotten the same result more then once that way?
