MC-12 Setup
3-39
CHECKING THE MICROPHONES
Note the following:
• The MC-12 outputs calibration noise signals between 55 and
95dB, beginning with 55dB and increasing in 5dB increments
until the microphones detect the required level. If the calibra-
tion noise signal becomes too loud, press the arrow button
to cancel the microphone check.
• Although the calibration noise signal is output at a fixed
volume level, you should set all volume controls for associated
components (i.e. speakers, subwoofers, and power amplifiers)
to a reasonable level before performing automatic calibration.
When the procedure is finished, the MC-12 automatically
reverts to the last volume level that was selected before
automatic calibration began.
• During automatic calibration, you should refer to the on-screen
display instead of the front panel display, as additional informa-
tion and instructions are available on the on-screen display.
1. Select the SPEAKER SETUP menu CHECK MICROPHONES
option as shown above.
2. The first CHECK MICROPHONES screen opens in the on-screen
display, indicating the importance of proper microphone
placement to achieve accurate automatic calibration results.
3. Press the arrow button to begin the microphone check. The
following screens appear in the on-screen display as the micro-
phone check is performed:
CHECKING FOR SILENCE
Appears in the on-screen display while
the MC-12 determines the relative noise
level of the listening space and the
internal noise level of the microphones.
After eliminating microphones that are
not detected or not functioning, the MC-12 calculates an aver-
age level for all microphones.
CHECKING MICROPHONES
Appears in the on-screen display while
the MC-12 confirms the microphone
level calculated during the silence
check. To do this, the MC-12 sends
alternating calibration noise signals to
the front left and right speakers. These signals are output
between 55 and 95dB, beginning with 55dB and increasing in
5dB increments until the microphones detect the required
