Preparing the Receiver Using AUTO CALIBRATION (Europe, Australia and Taiwan models only) This receiver is equipped with DCAC (Digital Cinema Auto Calibration) Technology which allows you to perform automatic calibration as follows: • Check the connection between each speaker and the receiver.* • Adjust the speaker level. • Measure the distance of each speaker from your seating position.* • Measure the speaker size.* • Measure the frequency characteristics.* * The measurement result is not utilized when "A. DIRECT" is selected. The DCAC is designed to achieve proper sound balance for your room. However, you can adjust the speaker levels manually according to your preference. For details, see "Adjusting the speaker levels (TEST TONE)" (page 35). Notes • The speakers emit very loud sound during the calibration and the volume cannot be adjusted. Provide consideration to your neighborhood and to the children in presence. • If the muting function has been activated before you perform Auto Calibration, the muting function will shut off automatically. • The correct measurements may not be able to take or Auto Calibration cannot be performed when special speakers, such as dipole speakers are used. 1: Setting up the Auto Calibration Optimizer microphone Example of using surround back speakers Before you perform Auto Calibration Before you perform Auto Calibration, check the following items: • Set up and connect the speakers (page 17, 19). • Connect only the supplied optimizer microphone to the AUTO CAL MIC jack. Do not connect any other microphones to this jack. • Disconnect the headphones. • Remove any obstacles in the path between the optimizer microphone and the speakers to avoid measurement error. • Get accurate measurement by making sure the environment is free from noise and quiet. 1 Select the speaker pattern (page 30). If you connect front high speakers, select the speaker pattern that has front high speakers (5/x.x or 4/x.x) each time you perform Auto Calibration. Otherwise, the characteristics of the front high speakers cannot be measured. 2 Connect the supplied optimizer microphone to the AUTO CAL MIC jack. continued 31GB
