Hello, i have a problem right at the start at calibration. I used the Behringer ECM 8000 to measure, connected via Scarlet 2i2 sound card. I was using measurement tutorial from Room EQ Wizard on youtube. At preferences window i set up the Output device Speaker and Input device Scarlet 2i2. During the calibration i put the microphone close to the speaker (the gain on the sound card is the maximum on both the channels and the master gain), but the volume gets only about -30 dBFS, reaching -12 dBFS. Where can be the problem ? Thanks for your answers.
