08.07.2007 — THX has introduced THX Loudness Plus, a volume control technology featured in THX Ultra2 Plus and THX Select2 Plus certified pre-amplifiers.

Loudness Plus is designed to maintain the impact and integrity of audio content when users are listening at lower volume settings.

Because most movie soundtracks are mixed at Reference Level for playback in a commercial theater, consumers end up missing out on some low-frequency information and subtle surround effects when playing them quieter at home.

"Most consumers don't have listening environments where they can consistently play movies and games at Reference Level," says Warren Mansfield, director of consumer technology at THX. "With THX Loudness Plus, home theater enthusiasts have the option of cranking the sound or turning the volume down and still hearing the ambient detail in movies, video games or music soundtracks just like they were mixed in the studio."

The first product to incorporate this new processing is the newly announced THX Ultra2 Plus certified Yamaha AVR RX-Z11 flagship A/V receiver.
