Confirms that the microphones are properly connected and functioning.
Calculates an average level for the microphones connected to the microphone input connectors, allowing the
MC-12 to compensate for individual microphone sensitivities during automatic calibration.
Ensures that microphone levels are consistent, eliminating automatic calibration errors from individual
microphone levels.
Activates automatic calibration of speaker distances and output levels.
Offers accurate calibration with minimal interaction, automatically applying calibrated speaker distances and
output levels.
Calibrates speaker distances within 0.5 foot (.15m) of the physical distance between the primary listening
position and the speaker.
Calibrates individual speaker output levels within +/-0.5dB of each other and overall speaker output levels
within +/-3.0dB of THX reference levels (75dB).
