Select this feature to allow you to adjust the balance of the right and left speakers’ sound output.

Incredible Surround

You can hear an incredible sound with extra depth and an unbelievable three- dimensional effect that surrounds you completely without the need for additional surround speakers.

Ultra Bass

Select this feature to enhance the bass quality of small loudspeakers. Non- audible low-frequency signals are replaced by harmonics, making them audible giving the impression that low-frequency signal is present.

AVL (Auto Volume Leveller)

Variation in signal conditions can result in a sudden change in volume during commercial breaks or channel switching. Activating the Auto Volume Leveller feature enables the volume level to remain at a standard volume level.
