THX Loudness Plus
THX Loudness Plus is a new volume control
technology featured in THX Ultra2 Plus™, THX
Select2 Plus™ and THX I/S 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.
