REPOSITIONING THE MICROPHONES FOR AUTOMATIC CALIBRATION

Proper microphone placement is essential to achieve the desired automatic calibration results. Microphone placement determines whether the MC-12 calibrates optimal results for a single listening position; several listening positions in a single row; or several listening positions in the listening room.

For best results, automatic calibration should be performed with four microphones that have passed the microphone check. But, the MC-12 performs automatic calibration as long as at least one microphone has passed the microphone check. In this case, place the successfully checked microphone in the primary listening position.
