8:Calibrating the appropriate settings automatically
(AUTO CALIBRATION)
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.a)
•Adjust the speaker level.
•Measure the distance of each speaker from your listening position.a)
•Measure the speaker size.a)
•Measure the speaker polarity.
•Measure the frequency characteristics.a)b)
a)The measurement result is not utilized in the following cases.
– ANALOG DIRECT is selected.
b)The measurement result is not utilized in the following cases.
–Dolby TrueHD signals with a sampling frequency of more than 96 kHz are being received.
–PCM signals with a sampling frequency of more than 96 kHz are being received.
The DCAC is designed to obtain proper sound balance in your room. However, you can adjust the speaker levels and balance manually according to your preference. For details, see “9: Adjusting the speaker levels and balance (TEST TONE)” (page 37).
Before you perform Auto
Calibration
Before you perform the Auto Calibration, set | Getting | |
| ||
up and connect the speakers (page 16, 17). |
| |
• The AUTO CAL MIC jack is used for the | Started | |
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. The volume |
| |
of the sound cannot be adjusted. 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. |
