“I wanted to test the Dirac Live filtering of the Maestro M9. So I ran the below test in the same set up as described above. But this time, the Dirac Live was engaged. The output signal is the inverse of the room response for the left speaker. The system has some aggressive correction and the corrected curve is multi-faceted which indicates that the Maestro M9 contains a reasonably powerful DSP engine. Note that the signal starts to roll off around 22 kHz which indicates that the A/D to D/A process takes place at a sampling rate of around 44 kHz.”
