MC-12 Setup
3-51
Message Description Troubleshooting
The MC-12 successfully calibrated the value
for the selected speaker without error.
•N/A
The selected speaker is not present in the
speaker setup
• Set the corresponding CUSTOM or THX SETUP menu parameter to include the selected
speaker in the speaker setup. (The MC-12 only calibrates values for speakers that are included
in the speaker setup.)
The microphones detected out-of-phase
calibration noise signals, but the cali-
brated value is still accurate.
• Examine speaker/associated amplifier connections to ensure that speaker wires are not crossed.
• Dipolar speakers could 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.
• Reflections from room objects can cause an out of phase error.
• Drivers intentionally wired out-of-phase.
The microphones detected calibration
noise signals at an unusually low level.
• 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 placement examples on pages
3-42 to 3-46 to confirm that the microphones are appropriately positioned for automatic calibration.
• Examine microphone input connections to ensure that the microphones are properly con-
nected to the MC-12 and that microphone cable plugs are fully inserted for a solid connection.
The microphones did not detect calibra-
tion noise signals or the MC-12 could not
calculate a value.
• Refer to the microphone placement examples on pages 3-42 to 3-46 to confirm that the
microphones are appropriately positioned for automatic calibration.
• Examine microphone input connections to ensure that the microphones are properly con-
nected to the MC-12 and that microphone cable plugs are fully inserted for a solid connection.
One or more microphones did not detect
calibration noise signals at a reasonable
level. The calibrated value could be inac-
curate.
• Refer to the microphone placement examples on pages 3-42 to 3-46 to confirm that the
microphones are appropriately positioned for automatic calibration.
The microphones detected calibration
noise signals at an unusually high level.
• Decrease associated amplifier volume levels – including (if applicable) powered subwoofer amplifiers.
• The microphones may be positioned too close (within 2 feet [0.61m]) of the selected speaker.
Refer to the microphone placement examples on pages 3-42 to 3-46 to confirm that the micro-
phones are appropriately positioned for automatic calibration.
The microphones detected calibration
noise signals at an unusually low level.
• Increase associated amplifier volume levels – including (if applicable) powered subwoofer amplifiers.
• The microphones may be positioned too far away (more than 30 feet [9.14m]) from the
selected speaker. See the microphone placement examples on pages 3-42 to 3-46 to confirm
that the microphones are appropriately positioned for automatic calibration.
