2-1 MRAC (Marantz Room Acoustic Calibration)
Speaker settings that would be difficult to configure
using manual setup can now be performed by
automatically measuring speaker characteristics
using the microphone.
Measurement
During measurement, a test tone is output from the
speakers, which is then measured and analyzed
though the microphone. The item and the order in
which they are measured are as follows:
AUTO SETUP 1
AMBIENT NOISE: Ambient noise measurement
SPEAKER CHECK: Speaker connected/not
connected check
PHASE CHECK: Speakers phase check
AUTO SETUP 2
Results from the measurements are checked.
AUTO SETUP 3

FLAT MODE: Speaker frequency measurement.
This measurement identifies the frequency required
to compensate the sound to the flat level.
FRONT MODE: Speaker frequency measurement.
This measurement identifies the frequency required
to match the front speaker characteristics.
