E-3

The SETTING DISTANCES screen shown above will open on the on-screen display while the MC-12

 

calibrates speaker distances.

 

During speaker distance calibration, the MC-12 sends calibration noise signals to the Main Zone

 

 

audio output connectors in the order shown on the SETTING DISTANCES screen. The cursor

 

 

automatically scrolls downward through speaker calibration parameters, highlighting each

 

 

parameter while the MC-12 calculates a distance for the corresponding speaker. When finished, the

 

 

MC-12 enters the calibrated value or an ERROR message to the right of the parameter label.

 

Because of the way low-frequency signals propagate in most listening spaces, automatic speaker

 

 

distance calibration often produces unreliable results for subwoofers and LFE subwoofers. For this

 

 

reason the MC-12 does not send calibration noise signals to the Subwoofer L/R and LFE output

 

 

connectors during speaker distance calibration. Instead, the MC-12 automatically calibrates

 

 

subwoofer and LFE subwoofer distances to the shortest distance of the other speakers. These

 

 

distances can be manually adjusted on the SPEAKER DISTANCES menu (page 3-52).

 

 

 

This step does not occur when the AUTO SPEAKER SETUP menu LEVELS option is selected.

E-4

This step does not occur when the AUTO

 

SPEAKER SETUP menu DISTANCES option is

 

selected.

The SETTING LEVELS screen shown above will open on the on-screen display while the MC-12 calibrates output levels.

The MC-12 sends calibration noise signals to the Main Zone audio output connectors in the order shown on the SETTING LEVELS screen. The cursor automatically scrolls downward through speaker calibration parameters, highlighting each parameter while the MC-12 calculates an output level for the corresponding speaker. When finished, the MC-12 enters the calibrated value or an ERROR message to the right of the parameter label.
