Configuring the MC-12 for V4 EQ Lexicon MC-12 Controller

Procedure	Description
CHECK MICROPHONES	Examines the microphones connected to the rear panel microphone input connectors.
	✓ Confirms that the microphones are properly connected and functioning.
	✓ Calculates an average microphone level, allowing the MC-12 to compensate for individual microphone sensitivities.
	✓ Ensures that microphone levels are consistent, eliminating errors that result from individual microphone level differences.
EQ DISTANCES LEVELS	Calibrates the listening room’s bass response, loudspeaker distances, and loudspeaker output levels.
	✓ Requires minimal interaction.
	✓ Measures the listening room’s bass resonance characteristics.
	✓ Applies appropriate room correction to the loudspeakers to minimize bass resonances.
	✓ Sets the AUDIO CONTROLS menu ROOM EQ parameter to ON and ROOM EQ LEVEL parameter to MEDIUM. These parameters can
	now be used to activate and deactivate room correction and to control the amount of room correction applied to the loudspeakers.
	Refer to Adjusting Room Correction (page 2-21).
	✓ Calibrates loudspeaker distances within ±0.5 foot (0.15m) of the physical distance between the listening position(s) and the loudspeaker.
	✓ Calibrates individual loudspeaker output levels within ±0.5dB of each other.
	✓ Calibrates overall loudspeaker output levels within ±3.0dB of THX reference levels (75.0dB).
	✓ Automatically applies calibrated loudspeaker distances and output levels.
ROOM EQ	Calibrates the listening room’s bass response.
	✓ Measures the listening room’s bass resonance characteristics.
	✓ Applies appropriate room correction to the loudspeakers to minimize bass resonances.
	✓ Sets the AUDIO CONTROLS menu ROOM EQ parameter to ON and ROOM EQ LEVEL parameter to MEDIUM. These parameters can
	now be used to activate and deactivate room correction and to control the amount of room correction applied to the loudspeakers.
	Refer to Adjusting Room Correction (page 2-21).
DISTANCES	Calibrates loudspeaker distances.
	✓ Calibrates loudspeaker distances within ±0.5 foot (0.15m) of the physical distance between the listening position(s) and the loudspeaker.
	✓ Provides a comparison between original and calibrated loudspeaker distances, allowing for selection of the desired distances.
OUTPUT LEVELS	Calibrates loudspeaker output levels.
	✓ Calibrates individual loudspeaker output levels within ±0.5dB of each other.
	✓ Calibrates overall loudspeaker output levels within ±3.0dB of THX reference levels (75.0dB).
	✓ Provides a comparison between original and calibrated loudspeaker output levels, allowing for selection of the desired output levels.
