THX Loudness Plus
THX Loudness Plus is a new volume control tech-
nology featured in THX Ultra2 Plus™ and THX 
Select2 Plus™ Certified receivers. With THX Loud-
ness Plus, home theater audiences can now experi-
ence 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 auto-
matically applied when listening in any THX listen-
ing 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 con-
tent.
