![]() I’m not actually concerned too about the response of the speakers now, just that the measurements remained consistant between holmimpulse runs, which they did.Īs a sanity test I’ll calibrate the Microphone against itself. The microphones place in a mic stand about 1M from the speakers. Sound source is my “under construction” active stereo speakers with the Behringer UCA-202 connected via SPDIF output. So why not try and calibrate the ECM-8000 using an already calibrated Mic? I know there will be inherent loss of precision during the process, but the result may still be more accurate than the generic file. I had been using the “generic” ECM-8000 calibration curve, but there is a fair bit of info out there that there is quite a bit of variance between different examples of the ECM-8000. I already have a Behinger ECM-8000, but the Behringer isn’t calibrated, while the MiniDSP comes with a calibration file, you just download from their site keyed on the serial number of your unit.Īs you can see, the two units come in similar, but not the same packaging, and also look quite similar: ![]() I recently purchased a MiniDSP UMIK-1 calibrated USB measurement microphone to help with speaker tuning. Note: article incomplete, I need to tidy up the graphs and clarify what the lines are. ![]()
