level. If the signal becomes too loud, press the arrow button
to cancel the microphone check.
The MC-12 uses the calibration noise signal to eliminate micro-
phones that register the signal at a level that is too low or too
high. Then, the MC-12 determines the appropriate output level
for the calibration noise signal used during automatic calibration.
CHECK MICROPHONES Results
Appears on-screen when the MC-12 is finished checking the
microphones. This display indicates the individual check results
for each microphone.
• An OK result indicates that the microphone passed the
microphone check.
• An ERROR result indicates that the microphone did not pass
the microphone check.
4. Press the and arrow buttons to highlight the desired
microphone parameter. The MC-12 refers to the microphones
according to the input connector to which the microphone is
connected.
5. Press the arrow button to view more detailed results for the
selected microphone. A message similar to the one shown at
the bottom of the previous column opens in the on-screen
display. Refer to the table on the next page for information
about all possible microphone check messages.
Note the following:
• The MC-12 retains the calculated microphone level until the
SPEAKER SETUP menu is closed. Once this menu is closed,
another microphone check is required before automatic cali-
bration can be performed.
• For best results, you should perform automatic calibration with
four microphones that have passed the microphone check.
However, the MC-12 will perform automatic calibration as long
as at least one microphone passes the microphone check. In
this circumstance, place the successfully checked microphones
in the primary listening position.
• If a microphone check was successful, do not disconnect the
microphones from the microphone input connectors. If the
microphones are disconnected, you should perform the micro-
phone check again before proceeding to automatic calibration.
