STEP DISTANCES
The SETTING DISTANCES menu is displayed when the MC-8 calibrates speaker distances.
• During speaker distance calibration, the MC-8 sends calibration noise signals to the Main Zone
audio output connectors in the order shown on the SETTING DISTANCES menu. The cursor auto-
matically scrolls downward through speaker calibration parameters, highlighting each parameter
while the MC-8 calculates a distance for the corresponding speaker. As it finishes each parameter,
the MC-8 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. For this reason, the MC-8 does not
send calibration noise signals to the Subwoofer connector during speaker distance calibration. Instead,
the MC-8 automatically calibrates the subwoofer distance to the shortest distance of the other speak-
ers. These distances can be manually adjusted. See "PERFORMING MANUAL SPEAKER DISTANCE CAL-
IBRATION" on page 3-53.
This step does not occur when the AUTO SPEAKER
SETUP menu DISTANCES option is selected.

DISTANCES & LEVELS
The SETTING LEVELS menu is displayed when the MC-8 calibrates output levels.
• During speaker levels calibration, the MC-8 sends calibration noise signals to the Main Zone
audio output connectors in the order shown on the SETTING LEVELS menu. The cursor auto-
matically scrolls downward through speaker calibration parameters, highlighting each parame-
ter while the MC-8 calculates an output level for the corresponding speaker. As it finishes each
parameter, the MC-8 enters the calibrated value or an ERROR message to the right of the
parameter label.
