THX Loudness Plus
THX Loudness Plus is a new volume control technology mounted on THX Ultra
and THX Select-certied receivers. With THX Loudness Plus, home theater
audience can experience the rich details of surround sound at any volume
level.
If the volume is turned down below the reference level, elements of sound in a
certain range are lost or the sound is perceived dierently by the listener.
THX Loudness Plus compensates for the tonal and spatial shifts that occur
when the volume level is reduced, by intelligently adjusting the levels of the
surround channels and their frequency response in the environment.
This enables users to experience the true impact of soundtracks regardless of
the volume setting. THX Loudness Plus is automatically applied when listening
in any THX listening mode. In the newly developed THX Cinema, THX Music
and THX Games modes, the optimum THX Loudness Plus setting is applied
according to the type of content.
