Ordinarily, the 5.1 channel speaker system needs two front speakers, a
center speaker, two surround speakers, and a subwoofer.
This system employs the Air Surround technology that enables you to
enjoy the surround sound with the front left and right speakers in the
center system; you can hear the center and surround channel sounds
without the corresponding speakers.
In this section, you can adjust the following surround sound settings for your preference and the characteristics of your
listening room:
