    Just got new umik from csl. After REW sees it and I point it to the first 0deg file supplied with the usb sick, REW puts up a mssg box that says it doesn’t contain a cal file. I’ve emailed csl but I figured I’d ask y’all while waiting for a response. Thx! Btw...have y’all done a measurement...

  6. Umik-1 problem ? Rew problem ? Dirac problem ?

    REW Forum
    I was doing measurement for a new calibration file for Dirac Live. I was surprised by the graph (db level difference between left and right channel). When I created my filter Dirac applied a 3db gain difference between the channel. It sounded totally wrong. I took another measurement with REW...

    REW Forum
    Hi, I bought the Mini DSP UMIK-1 microphone and when comparing the SPL meter in REW to the classic radio shack SPL meter, the REW measurement is 5db hotter. I have the correct calibration file loaded for the microphone, could it be something else? Thanks, Sean.

    REW Forum
    Hello, I'm trying to calibrate my simple stereo speaker setup so I can use this setup with Pro Tools for small post-production audio jobs. I have a smaller room so I want to calibrate the speakers to 78 dB. I received my miniDSP UMIK-1 mic from Cross Spectrum, which currently I want to use as...
  15. UMIK-1 gain loss problem

    SPL Meters | Mic's | Calibration | Sound Cards
    UMIK-1 suddenly shows very lowered noise floor: in quiet room, previously about -45 dB, now shows -75 Db or so, about 30 dB off. And it shows in the measurements (REW, also Holm), all are rejected as "low level" . The unit does react - the record meters "jump" - but the overall level is 30 dB...

    I am currently looking for ways to get e.g. the UMIK-1 wireless and, beside that, solar powered. The problem is to be able to place measurement microphones, where it makes sense from an acoustic point of view, without having to cope with cables. Typical wireless microphones don't have the...

    SPL Meters | Mic's | Calibration | Sound Cards
    Hello Everybody, I plan to buy a MiniDSP UMIK-1 microphone for equalizing my music room using REW and a DEQ2496. The PC and the equalizer will be rather far (> 5 m) from the listening place. I thus need a long USB extension cable. I wonder whether an active extension cable such as the ones sold...
