MIC CHECK

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

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, it is recommended to 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, it is recommended to refer to the on-screen display rather than the front panel display, as addi- tional information and instructions are available on the on- screen display.
