Measuring the distance of each speaker from
your listening position.
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 33).
Before you perform Auto Calibration, install
