Calibration
Refer to the table below for information about errors occuring during
the Run Automatic Calibration procedure.
ERROR
MESSAGE
DESCRIPTION TROUBLESHOOTING
(speaker)
SPEAKER IS NOT
ENABLED
The selected speaker is not present in
the speaker setup.
• Return to the Speaker Setup menu and verify that the
speaker has been activated. The parameter value must
be Yes to be active.
(speaker)
SPEAKER IS OUT OF
PHASE
The microphones detected out-of-
phase calibration noise signals, but
the calibrated value is still accurate.
• Examine the speaker/associated amplifier connections
to ensure that the speaker wires are not crossed.
• Dipolar speakers could cause this error. However, the
Nº502 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 can cause an
out-of-phase error.
(speaker)
SIGNAL TOO LOW
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 discussed in Chapter 3 to
confirm that the microphones are appropriately
positioned for automatic calibration.
• Examine the microphone input connections to ensure
that the microphones are properly connected to the
Nº502 and that the microphone cable plugs are fully
inserted for a solid connection.
(speaker)
UNABLE TO
CALCULATE
The microphones did not detect
calibration noise signals or the Nº502
could not calculate a value.
• Refer to the placement examples discussed in Chapter
3 to confirm that the microphones are appropriately
positioned for automatic calibration.
• Examine the microphone input connections to ensure
that the microphones are properly connected to the
Nº502 and that the microphone cable plugs are fully
inserted for a solid connection.
(speaker)
MAY NOT BE
ACCURATE
One or more microphones did not
detect calibration noise signals at a
reasonable level. The calibrated value
could be inaccurate.
• Refer to the placement examples discussed in Chapter
3 to confirm that the microphones are appropriately
positioned for automatic calibration.
(speaker)
SPEAKER OUTPUT
TOO HIGH
(only affects the
Speaker Levels
calibration)
The microphones detected
calibration noise signals at an
unusually high level.
• Decrease the associated amplifier volume levels –
including powered subwoofer amplifiers, if applicable.
• The microphone may be positioned too close, within 2
feet (0.61m), to the selected speaker. Refer to the
placement examples discussed in Chapter 3 to confirm
that the microphones are appropriately positioned for
automatic calibration.
(speaker)
SPEAKER OUTPUT
TOO LOW
(only affects the
Speaker Levels
calibration)
The microphones detected
calibration noise signals at an
unusually low level.
• Increase the associated amplifier volume levels -
including powered subwoofer amplifiers, if applicable.
• The microphone may be positioned too far away, more
than 30 feet (9.14m), from the selected speaker. Refer
to the placement examples previously discussed to
confirm that the microphones are appropriately
positioned for automatic calibration.
