The MC-12 calibrated the value for
the selected speaker without error.
The selected speaker is not present in
the speaker setup.
The microphones detected out-of-
phase calibration noise signals, but
the calibrated value is still accurate.
The microphones detected calibration
noise signals at an unusually low level.
The microphones detected calibration
noise signals at an unusually low level.
The microphones detected calibration
noise signals at an unusually high
level.
The microphones did not detect
calibration noise signals or the MC-12
could not calculate a value.
One or more of the microphones did
not detect calibration noise signals at
a reasonable level. The calibrated
value might be inaccurate.
• N/A
• Set the corresponding CUSTOM or THX SETUP menu parameter to include the selected speaker in the speaker
setup. (The MC-12 does not calibrate values for speakers that are not present in the speaker setup.)
• Examine the connections between the speaker and the associated amplifier to ensure that speaker wires are
not crossed.
• Dipolar speakers might cause this error. However, the MC-12 does not report this error unless at least half
of the microphones detect out-of-phase calibration noise signals.
• The microphones might be positioned more than 30 feet (9.14m) from the selected speaker or in a location
where echoes obscure calibration noise signals. Refer to the microphone placement examples that begin on
page 3-41 to confirm that the microphones are appropriately positioned for automatic calibration.
• Examine microphone input connections to ensure that the microphones are properly connected to the
MC-12 and that microphone cable plugs are fully inserted for a solid connection.
• Refer to the microphone placement examples that begin on page 3-41 to confirm that the microphones
are appropriately positioned for automatic calibration.
• Examine microphone input connections to ensure that the microphones are properly connected to the
MC-12 and that microphone cable plugs are fully inserted for a solid connection.
• Decrease associated amplifier volume levels – including, if applicable, built-in subwoofer amplifiers.
• The microphones might be positioned within 2 feet (0.61m) of the selected speaker. Refer to the microphone
placement examples that begin on page 3-41 to confirm that the microphones are appropriately positioned
for automatic calibration.
• Increase associated amplifier volume levels – including, if applicable, built-in subwoofer amplifiers.
• The microphones might be positioned more than 30 feet (9.14m) from the selected speaker. Refer to the
microphone placement examples that begin on page 3-41 to confirm that the microphones are appropriately
positioned for automatic calibration.
