bass balance.

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.
