The SETTING DISTANCES screen displays when 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 auto-
matically scrolls downward through speaker calibration parameters, highlighting each parameter
while the MC-12 calculates a distance for the corresponding speaker. As it finishes each parameter,
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 dis-
tance 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. See “PERFORMING MANUAL SPEAKER DISTANCE CALIBRATION” on page 3-53.
The SETTING LEVELS screen displays when 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 calcu-
lates an output level for the corresponding speaker. As it finishes each parameter, the MC-12
enters the calibrated value or an ERROR message to the right of the parameter label.
