THX Loudness Plus
THX Loudness Plus is a new volume control 
technology featured in THX Ultra2 Plus™ and THX 
Select2 Plus™ Certified receivers. With THX Loudness 
Plus, home theater audiences can now experience the 
rich details in a surround mix at any volume level. A 
consequence of turning the volume below Reference 
Level is that certain sound elements can be lost or 
perceived differently by the listener. THX Loudness 
Plus compensates for the tonal and spatial shifts that 
occur when the volume is reduced by intelligently 
adjusting ambient surround channel levels and 
frequency response. This enables users experience the 
true impact of soundtracks regardless of the volume 
setting. THX Loudness Plus is automatically applied 
when listening in any THX listening mode. The new 
THX Cinema, THX Music, and THX Games modes are 
tailored to apply the proper THX Loudness Plus settings 
for each type of content.
