The DDRC-24 processor executes Dirac Live® digital room correction, from Dirac Research . Dirac Live’s mixed -
phase filtering technology will improve the imaging of your system, minimize the effects of room modes and
resonances, and improve dynamics and clarity.
To accomplish its remarkable improvement in listening quality, the DiracLive application steps you through the
procedure for taking measurements around your listening area. Dirac Live® employs a sophisticated analysis
algorithm to make the optimal correction across the
whole listening area, not just at a single point. The user has
full control over the target frequency response. Measurements are taken with a calibrated acoustic
measurement microphone, the miniDSP UMIK-1.

In addition to correcting magnitude response, Dirac Live® corrects the system’s impulse response , which reflects
how the system responds to a sharp transient such as a drumbeat. Reflections, diffraction, resonances,
misaligned drivers, and so on, all combine to smear out the transient. Correcting the impulse response makes
the speaker in the room behave much more like an ideal loudspeaker. The impulse response is a critical factor
for accurate sound-staging, clarity and bass reproduction.
Dirac Live calibration is described in the separate miniDSP Dirac Live User Manual .

We
recommend
that you add a UMIK-1 to your order if you do not already have one.
