Press the and arrow buttons to highlight the CHECK MICROPHONES procedure. The CHECK MICROPHONES screen (shown above) opens on the on-screen display, emphasizing the importance of proper microphone placement to achieve the desired automatic calibration results. Refer to Positioning the Microphones for the Microphone Check (page 2-6) to ensure that the microphones are properly positioned for the microphone check. The CHECKING FOR SILENCE message (shown above) appears on the on-screen display while the MC-12 determines the relative noise level of the listening room and the internal noise level of the microphones. After eliminating microphones that are not detected or not functioning, the MC-12 calculates an average microphone level. The CHECKING MICROPHONES message (shown above) appears on 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 loudspeakers, eliminating microphones that detect the signal at an unusually low or high level. Then, the MC-12 determines the appropriate output level for the calibration noise signal used during automatic calibration. Note: The MC-12 outputs calibration noise signals between 55 and 95dB, starting at 55dB and increasing in 5dB increments until the microphones detect the required level. If calibration noise signals become too loud, press the arrow button to cancel automatic calibration. 2-8 EQ User Guide The CHECK MICROPHONES results screen (shown to the right) opens on the on-screen display when the MC-12 finishes checking the microphones.
