Step DISTANCES or OUTPUT LEVELS EQ DISTANCES LEVELS ROOM EQ

5	This step does not occur during the DISTANCES
	or OUTPUT LEVELS procedures.

The SETTING ROOM EQ screen (shown above) opens on the on-screen display while the MC-12 meas- ures the listening room’s bass response. To do this, the MC-12 sends calibration noise signals to the loudspeakers connected to the Main Zone audio output connectors in the order shown on the screen. The cursor automatically scrolls downward, highlighting each parameter while the MC-12 applies appropriate room corrections to the corresponding loudspeaker. When finished, the MC-12 enters SET to the right of the parameter label.

6	The SETTING DISTANCES or SETTING LEVELS screen (shown above) opens on the on-screen display
	while the MC-12 calibrates loudspeaker distances or output levels. To do this, the MC-12 sends
	calibration noise signals to the loudspeakers connected to the Main Zone audio output connectors in
	the order shown on the screen. The cursor automatically scrolls downward, highlighting each parameter
	while the MC-12 calculates a distance or output level for the corresponding loudspeaker. When finished,
	the MC-12 enters the calculated value or ERROR to the right of the parameter label.

Note the following:

•During the EQ DISTANCES LEVELS procedure, the SETTING DISTANCES screen opens on the on-screen display while the MC-12 calibrates loudspeaker distances. Then, the SETTING LEVELS screen opens on the on-screen display while the MC-12 calibrates loudspeaker output levels.

•In most listening rooms, low-frequency signal propagation makes automatic loudspeaker distance calibration unreliable for subwoofers and LFE subwoofers. Because of this, the MC-12 does not send calibration noise signals to subwoofers. Instead, the MC-12 calibrates these loudspeaker distances to the average distance of the front left and right loudspeakers. If desired, the SPEAKER DISTANCES menu can be used to manually adjust subwoofer distances.

This step does not occur during the ROOM EQ procedure.
