7:Calibrating the appropriate settings automatically (AUTO

CALIBRATION)

The DCAC (Digital Cinema Auto Calibration) function allows you to perform automatic calibration, such as checking the connection between each speaker and the receiver, adjusting the speaker level, and measuring the distance of each speaker from your listening position automatically. Refer also to the “Quick Setup Guide” supplied with the receiver.

Before you perform auto calibration

Before you perform the auto calibration, set up and connect the speakers (page 16, 17).

•The AUTO CAL MIC jack is used for the supplied optimizer microphone only. Do not connect other microphones to this jack. Doing so may damage the receiver and the microphone.

•During the calibration, the sound that comes out of the speakers is very loud. Pay attention to the presence of children or to the effect on your neighborhood.

•Perform the auto calibration in a quiet environment to avoid the effect of noise and get a more accurate measurement.

•If there are any obstacles in the path between the optimizer microphone and the speakers, the calibration cannot be performed correctly. Remove any obstacles from the measurement area to avoid measurement error.

•When you use a bi-amplifier connection, set “SUR BACK SP” to “BI-AMP” in the Speaker Settings menu before you perform auto calibration (page 64).

Notes

•The auto calibration function does not work in the following cases.

–MULTI IN is selected.

–The ANALOG DIRECT function is being used.

–Headphones are connected.

•Cancel MUTING if it is set to on.

Optimizer microphone

1 Connect the supplied optimizer microphone to the AUTO CAL MIC jack on the front panel.

2 Set up the optimizer microphone.

Place the optimizer microphone at your listening position. Use a stool or tripod so that the optimizer microphone remains at the same height as your ears.

On setting up the active sub woofer

•When a sub woofer is connected, turn on the sub woofer and turn up the volume beforehand. Turn the VOLUME knob to just before the mid-point.

•If you connect a sub woofer with a crossover frequency function, set the value to the maximum.

•If you connect a sub woofer with an auto standby function, set this function to off (deactivated).
