Contents ≫ Connections ≫ Playback ≫ Setup ≫ Full Auto MCACC Place the supplied speaker setup microphone in the listening position, measure the test tones emitted by the speakers, then the unit automatically sets the optimum volume level for each speaker, the crossover frequencies, and the distance from the listening position. The influence of standing waves can be reduced to suit the listening environment, the reverberation characteristics can be measured to increase the precision of calibration, the speaker equalizers can be adjusted, and the difference in phase and timing between speakers and speaker units can be corrected. These settings and calibrations can be readjusted with Manual MCACC, and you can enable or disable them in AV Adjust. • Calibration takes between 3 and 12 minutes to be completed. The speakers emit the test tone at high volume during measurement, so be careful of your surroundings. Keep the room as quiet as possible during measurement. • If you connect a subwoofer, check the power and volume of the subwoofer. Set the subwoofer volume to more than half. • If the power of this unit suddenly turns off, the wires in the speaker cables have touched the rear panel or other wires, and the protection circuit is working. Twist the wires again securely, and make sure they do not stick out of the speaker terminals when connecting. 1. Select the connected speaker configuration.

If there is no problem in the detection result of the speaker, select "Next" and press ENTER to output the test tone again to automatically set the settings such as volume level, crossover frequency, etc., to their optimum. (The test tone is automatically output when 10 seconds has elapsed without any operation.) • When an error message is displayed or when the connected speakers cannot be detected, perform re-measurement by selecting "Retry" and pressing ENTER. • When it cannot be resolved by performing the re-measurement, confirm if the speakers are connected correctly. If there is any problem with the speaker connection, perform the connection after disconnecting the power cord. 6. Once the measurement is completed, it is possible to perform the measurement in 8 additional listening positions. To perform the measurement, select "Next" and press ENTER, then follow the instructions. To not perform the measurement, select "Finish (Calculate)" and press ENTER. • After each listening position is detected, select "Finish (Calculate)" and press ENTER to complete the detection process. 7.
