MC-12 Setup

AUTOMATIC CALIBRATION

The MC-12 offers automatic calibration of speaker distances, output levels, or both. The table below indicates available automatic calibration options. A successful microphone check is required before automatic calibration can be performed.

Automatic Options	Details
MICROPHONE CHECK	• 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.
DISTANCES & 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 (.2m) 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).
DISTANCES	• Activates automatic calibration of speaker distances.
	• Provides a comparison between original and calibrated speaker distances, allowing selection of the
	desired values.
	• Calibrates speaker distances within 0.5 foot (.2m) of the physical distance between the primary listening
	position and the speaker.
LEVELS	• Activates automatic calibration of output levels.
	• Provides a comparison between original and calibrated output levels, allowing selection of the desired
	values.
	• Calibrates individual speaker output levels within +/-0.5dB of each other and overall speaker output
	levels within +/-3.0dB of THX reference levels (75dB).
