This works by controlling how sounds reach the listener's left and right ears. ˙ THX THX is a series of specifications for the accurate reproduction of movies propounded by the film director George Lucas. THX listening modes include the THX Cinema mode, and using technology such as THX Loudness Plus and Timbre Matching, the sound of a movie theater is reproduced accurately. THX technology: A movie soundtrack is mixed in large-scale theater specially made for mixing that is called a dubbing stage on the assumption that the soundtrack is played in such theaters with similar equipment and conditions. These sound tracks are recorded as is, even when recording to a DVD-Video, for example, without making any modifications to suit a home theater. THX technology is able to reproduce the theater sound in a home theater environment by minimizing acoustic and spatial deviation. • THX Loudness Plus THX Loudness Plus is a new volume control technology featured in THX Ultra and THX Select certified AV receivers. With THX Loudness Plus, home theater audiences 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 differently by audience. THX Loudness Plus compensates for the tonal and spatial shifts that occur when the volume level is reduced, by intelligently correcting the levels of the surround channels and their frequency response in the environment. • Re-EQ The speakers for the front channel are installed behind the screen in a movie theater. For this reason the high range is enhanced in the front channel of the sound track to take account of acoustic characteristics such as the necessity to penetrate the screen. Re-EQ adjusts soundtrack with enhanced high range to make it suitable for home theater. • Timbre Matching The perception of the human ear differs depending on the direction of the sound. Movie theaters have many surround speakers installed so they are great at surrounding the viewer with natural sound, but home theaters have only two surround speakers installed. The Timbre Matching function filters the signals sent to the surround speakers and adjusts the tonal characteristics of front speakers and surround speakers to create smooth sound movement from front speakers to surround speakers. • Adaptive Decorrelation Although movie theaters have many surround speakers to surround the room with sound, home theaters normally have only two surround speakers. Such two surround speakers give a headphone-like sound, not a broad and embracing surround sound. If the listener moves away from the middle of the surround speakers, sound from the surround speakers mixes with that from the near speakers and cannot be distinguished any more. Adaptive Decorrelation slightly changes the time axis and phase between the surround channels so you can enjoy the same kind of breadth of sound you can in a movie theater even with only two surround speakers. • ASA (Advanced Speaker Array) ASA is a technology patented by THX to provide a broad surround sound experience by adjusting the side and back surround speaker sounds respectively. When installing the surround back speakers, first select the distance between the two surround back speakers in the THX Audio settings. This setting optimizes the surround sound environment. THX listening modes: -- THX Cinema: Use in a home theater environment for playing a soundtrack that was recorded with the intention of it being played in a movie theater or similar large area. In this mode, THX Loudness Plus is set to the theater level and Re-EQ, Timbre Matching, and Adaptive Decorrelation are all enabled. -- THX Games: Use for high-fidelity spatial reproduction of game sound. THX Loudness Plus is set to a level suited to the audio level of the game and Timbre Matching is enabled. -- THX Music: Use mainly for music sources that are clearly mastered to a much higher quality than movie audio. THX Loudness Plus is set to a level suited to the playback of music and Timbre Matching is enabled. -- THX S Cinema (THX Select Cinema): The THX Select Cinema mode provides a high-quality surround sound experience by expanding movie sources recorded in 5.1 ch for 7.1 ch playback. In this mode, the THX ASA processing technology gives smooth transition between side and back surround sounds creating the best atmosphere and directional sense of surround sound. -- THX S Games (THX Select Games): Select the THX Select Games mode to play game sound recorded in a multichannel format. In this mode, the THX ASA processing technology creates a 360-degree sound field with game sound recorded in PCM, DTS, Dolby Digital and other 5.1 ch formats. -- THX S Music (THX Select Music): Select THX Select Music to play music sources recorded in a multichannel format. In this mode, the THX ASA processing technology creates a broad and stable back sound field for music sources recorded in 5.1ch such as DTS, Dolby Digital, and DVD-Audio. ˙ TV Logic Suitable for TV shows produced in a TV studio. This mode enhances the surround effects to the entire sound to give clarity to voices and create a realistic acoustic image. ˙ Unplugged Suitable for acoustic instruments, vocals and jazz. This mode emphasizes the front stereo image, giving the impression of being right in front of the stage. 35
