Hi there! You can manually optimize your audio experience by pressing the SOUND CONTROL button (looks like a gear) to access the setting items such as TREBLE, BASS, SYNC, CENTER LEVEL, SIDE LEVEL, FRONT TOP LEVEL, REAR LEVEL, REAR TOP LEVEL, and VIRTUAL ON/OFF. The selected item can be adjusted individually, using the Up/Down buttons. For more information regarding sound setting adjustments, please refer to the User Manual that is included with the HW-Q850T Soundbar. ^Gina
