THX Loudness Plus™
THX Loudness Plus™ maintains the integrity of soundtracks when listening below Reference Level (0 db on the volume dial for THX Certified Receivers is equal to the studio Reference Level). Loudness Plus automatically and seamlessly compensates for the tonal and spatial shifts that occur when the volume level is reduced. By increasing the levels of the ambient sound, you experience the true high-fidelity audio of movies, music and games at any volume.
