That item would work if you wanted to get the mic’s signal into the computer for the purposes of say, make a recording using a program like Audacity or Garage Band. But as brucek noted, for REW a sound card with line inputs and outputs is needed so that a calibration file can be generated. The calibration file is critical because it compensates for any deviation from flat that the sound card may exhibit. As you have figured out, to use the ECM8000 mic with REW, a mic pre amp with phantom power is needed, but it has to connect to the sound card, not directly to the computer. Alternately, a sound card with a built-in mic pre amp can be used; Tascam, E-MU and M-Audio and others make such products.

Thanks for the answers!

So if I want to use REW, I must connect the soundcard to my receiver with the line-out connections? Would digital connection not work? (Like HDMI/SPDIF).

No digital connections won't work, because the sound card can't be calibrated that way.

EDIT: Would this card be good? "M-AUDIO MOBILE PRE USB". And is it "tested" on REW?
I would rather have an external USB card. Then connect the ECM8000 to the usb-card, the card to the PC via USB, and use the line outs in the card to the receiver?

I believe the Pre USB will work, but you should do a search on this Forum and the REW Forum to make sure. If you can find a thread with a sound card calibration graph and/or a frequency response graph, then they were successful in using it.
