CHECKING THE MICROPHONES
Note the following:
• The MC-8 outputs calibration noise signals between 55dB and
95dB, beginning with 55dB and increasing in 5dB increments
until the microphones detect the required level. If the
calibration 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 compo-
nents (i.e., speakers, subwoofers and power amplifiers) to a
reasonable level before performing automatic calibration.
When the procedure is finished, the MC-8 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 infor-
mation and instructions are available in 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 appears in the on-screen display as the micro-
phone check is performed:
CHECKING FOR SILENCE
Appears in the on-screen display while
the MC-8 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-8 calculates an
average level for all microphones.
CHECKING MICROPHONES
Appears in the on-screen display while
the MC-8 confirms the microphone
level calculated during the silence
check. To do this, the MC-8 sends alter-
nating calibration noise signals to the
front left and right speakers. These signals are output between
55dB and 95dB, beginning with 55dB and increasing in 5dB
increments until the microphones detect the required
