check. To do this, the MC-12HD sends alternating calibration
noise signals to the front left and right speakers.
The MC-12HD uses the calibration noise signal to eliminate
microphones that register the signal at a level that is too low or
too high. Then, the MC-12HD determines the appropriate out-
put level for the calibration noise signal used during automatic
calibration.
CHECK MICROPHONES Results
Appears on-screen when the MC-12HD 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-12HD refers to the micro-
phones 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-12HD 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-12HD will perform automatic calibration as
long as at least one microphone passes the microphone check.
In this circumstance, place the successfully checked micro-
phones 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.
