Tired of hearing your speaker drone on without notice? You can make it louder by increasing the volume level, or you can tap on the equalizer for more nuanced adjustments. The Equalizer panel adjusts the sound frequencies that are supported by your speaker system and is optimally adjusted to bring out bass (lower) tones, midrange (middle) tones, and high end (treble) tones. Music lovers typically gravitate towards one of three presets: Standard, Classical, Rock.
