MC-12 Setup
3-35
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).
