The Intensity slider offers full control over the audio output, and allows you to adjust the Bass and Treble. Slide it up or down until you find your optimum level.
Please Note – To experience the 3D surround sound effect, please plug-in a headset/headphones.
When the 3D Surround feature is ON, even the Equalizer and Intensity becomes active and this cannot be undone. You can, however, use the Equalizer and Intensity features without the 3D Surround option.
