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. This also reduces the effect of the standing wave in accordance with the viewing environment and automatically adjusts the equalizers for the speakers and enables correction of distortion caused by the acoustic environment of the room. • 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. • If Full Auto MCACC has been executed, the speaker calibration made with Dirac Live ( →p168, p172) is disabled. 1.
