BEHRINGER ECM8000 CALIBRATION FILE REW DRIVERS

flat with some very high frequency artefacts from the DAC which I expected. Everything above the 4khz point out to 20khz looks great, i.e. What I got was a nasty rise in noise that started at 4khz and then increased gradually to a peak at 20hz. There was no audio output so that all I should be getting is pretty much silence, minus the noise floor of the UR22 and perhaps cable noise etc. I measured what the the UR22 was picking up by using an inbuilt real time analysis feature in the REW software. I then got the mic and stopped up the end with blu-tack, covered it in acoustic foam and bunged it in an airtight box - a poor mans anechoic chamber.

I was testing the drivers at about 80db and the low frequencies were matching the higher frequencies in dB which I knew was totally wrong. The roll off at low frequencies which I should have been getting were not showing in the response graphs. I repeated the measurements again with the midrange and the issue persisted. My unit doesnвЂ™t fit into the batches that are meant to be affected by the problem BUT, I was trying to do some tweeter measurements and I was getting a really strange response in REW. The Steinberg website warns that some UR22 units will create low-freq rumble when supplying phantom power to single condenser mics. This went well but from this point on I seem to be hitting a problem.

You also specify a microphone calibration file if you have one. In the software you create a loopback and measure the unitвЂ™s response which then gives you a calibration file to ensure your measurements are correct. I have been trying to do some serious testing with the UR22 and a Behringer ECM8000 combination using a program called Room EQ Wizard which can be used for this purpose.
