THX 1138 4EB

THX Ltd. is an American company that develops the eponymous high fidelity audio/visual reproduction standards for movie theaters, screening rooms, home theaters, computer speakers, gaming consoles, car audio systems, and video games. Founded on May 20, 1983 by George Lucas and headquartered in San Francisco, California, it is currently a subsidiary of Razer Inc.

THX was developed by Tomlinson Holman at Lucas's company Lucasfilm in 1983 to ensure that the soundtrack for the third ''Star Wars'' film, ''Return of the Jedi'', would be accurately reproduced in the best venues. THX was named after Holman's initials, with the "X" standing for "crossover" or "experiment"; the name is also an homage to Lucas's first film, ''THX 1138'' (1971). The distinctive glissando up from a rumbling low pitch used in the THX trailers, created by Holman's co-worker James A. Moorer, is known as the "Deep Note".

The THX system is a quality assurance system, not a recording technology. All sound recording formats, whether digital (Dolby Digital, DTS, SDDS) or analog (Dolby Stereo, Ultra Stereo), can be reproduced in a THX system. THX-certified theaters provide a high-quality, predictable playback environment to ensure that any film soundtrack mixed in THX will sound as near as possible to the intentions of the mixing engineer. THX also provides certified theaters with a special crossover circuit whose use is part of the standard. Certification of an auditorium entails specific acoustic and other technical requirements; architectural requirements include a floating floor, baffled and acoustically treated walls, non-parallel walls (to reduce standing waves), a perforated screen (to allow center channel continuity), and NC30 rating for background noise ("ensures noise from air conditioning units and projection equipment does not mask the subtle effects in a movie's soundtrack").

The current THX was created on June 12, 2002, when it was spun off from Lucasfilm and sold to sound card manufacturer Creative Technology Limited, which held a 60% share of the company. Under Creative Technology, the company would go on to develop several further innovations, such as the first THX-certified audio card for computers, the Sound Blaster Audigy 2. In 2016, THX was acquired by video game hardware company Razer Inc., with Razer owning all of THX and its intellectual property.

History

In 1982, George Lucas and his company Lucasfilm were gearing up to release ''Return of the Jedi'', the third film in the ''Star Wars'' trilogy. A new building had been constructed in San Rafael, California, where Industrial Light & Magic and much of Lucasfilm occupied a series of work bays and office complexes along Kerner Boulevard. Known as the C Building, the structure boasted a shooting stage, editing facilities, rooms for computer servers, and a large theater designed as a state-of-the-art sound mixing room. That same year, Lucas and his team were working on ''Return of the Jedi'' when a major situation began to arise. They brought their film to test in a commercial theater to find out that much of the audio detail and quality they mixed for countless hours in the studio was simply missing when played back in the cinema. Lucas's team was unable to hear the classic Princess Leia theme, as well as the famous ''Star Wars'' soundtrack and sound effects, and the background noise in the theater had become much worse, muffling most of the film's sound while playing through the theater's commercial sound system. During this time, many movie theaters all over the world had poor room acoustics with mono surround sound. The vision sounded one way in the studio and differently in the theater.

To fix the problem, Lucas would establish a quality standard for commercial theaters that would utilize the best technology to consistently translate filmmakers' work to the big screen. Tomlinson Holman, a skilled audio engineer and scientist largely responsible for the design of the theater, had become an employee of Lucasfilm in 1980. In the process of enhancing the setup for the new Sprocket Systems theater, Holman and Lucas invented a complex system that arranged speakers to best fit the architectural space within the theater. Using an intricate crossover network that integrated equipment with the room's unique acoustics, it became perhaps the best quality system anyone could remember hearing. Sprocket Systems mixed the ''Return of the Jedi'' sound in the room, the first Lucasfilm production mixed in Northern California. Visiting filmmakers and studio executives were astounded at what they heard. Jim Kessler, who hired Holman, thought of calling the system "Tomlinson Holman's Crossover", or, as originally abbreviated, "XVR". He then changed the "VR" and turned it into "TH", but he realized that was the name for George Lucas' first film, ''THX 1138'', and found that would be a fitting name. They eventually changed the "X"'s meaning to "experiment".

Four movie theaters in the United States would fully install their own THX sound system, becoming the first THX certified theaters. To introduce the new system, James A. Moorer created an ear-catching sound called the Deep Note. THX was dedicated on May 20, 1983, and the first trailer and Deep Note premiered on time with the release of ''Return of the Jedi'' in theaters five days later. It was billed as the first advance in the motion picture loudspeaker systems since 1948.

In 1990, Lucasfilm unveiled the Home THX Audio System at the Consumer Electronics Show in Chicago. That year, a demo LaserDisc dubbed ''Wow!'' was unveiled. It featured various clips from ''Star Wars'', ''Indiana Jones'' and ''Willow''. Three years later in 1993, ''The Abyss'' was released on LaserDisc, making it the first time THX was used on that device. In 1995, the Star Wars Trilogy was released on VHS and the entire trilogy would now be THX certified. This would be the first THX VHS release. In 1997, THX began to use the audio on the newly-released DVD device. ''Twister'' became the first DVD release to be digitally mastered by THX.

In early 2002, it was announced that Lincoln would become the first auto company to offer THX-certified premium car audio systems. A concept sound system for the Lincoln Blackwood would showcase the potential for in-car multi-channel surround sound, which could be seen and heard at the THX booth at the Consumer Electronics Show in Las Vegas. The license would ensure that high-performance audio systems in Lincoln vehicles met the exacting sound quality and performance standards of its new THX Ultra Premium Car Audio program, beginning with the 2003 Lincoln LS, which was introduced later that year.

THX separated from Lucasfilm and became an independent company in June 2002. The company would continue to be based in Marin County, California, with offices in Burbank and plan for international expansion. It would expand into gaming and car audio systems. On the professional front, THX planned to continue the expansion of its theatrical certification programs as it became more involved in digital cinema.

On September 30, 2003, THX announced that they would begin branding seals of approval to the audio produced for video games. Electronic Arts would be the first company to achieve the game certification. This move helped improve the game sound, measuring the credibility of games at a time when the industry saw itself as being important to the entertainment landscape. Five games by Electronic Arts, including '' Need for Speed: Underground'', '' Medal of Honor: Rising Sun'' and '' The Lord of the Rings: The Return of the King'' would carry logos on their box and pre-game trailers upon their release. In 2020, THX Certified Game Mode was introduced. This mode enhanced contrast and color while simultaneously reducing input lag. It also delivered fast response time and the most optimal viewing experience, allowing games to be experienced the way they were intended by the creators with richer vibrant colors and better contrast in crisp 4K HDR resolution. When customers selected the THX Certified Game Mode in their TV, they would know that the performance of every setting had been carefully calibrated and optimized to deliver impactful visual performance to reveal vivid detail in a game while keeping the fast responsiveness that serious gamers demand. Furthermore, THX Certified Game Mode even featured judder and smear reduction, meaning that the picture stayed crisp and a quick rise time between dark-to-light transitions. On August 3, TCL Technology revealed the first television to include THX Certified Game Mode, a 6-Series TCL Roku TV.

In 2006, THX began to certify high definition Blu-ray discs; the first THX-certified Blu-ray title was '' Terminator 2: Judgment Day''.

A 3D product certification called THX 3D Display premiered in 2010. The first 3D television to feature this technology was an LG Infinia PX950 Plasma HDTV series. To earn the new THX 3D Display Certification, the PX950 passed more than 400 laboratory tests evaluating left and right eye images for color accuracy, cross-talk, viewing angles, and video processing performance. In addition to the THX 3D Display Certification, the PX950 had to pass THX certification for picture quality in 2D, which must be achieved before passing THX 3D certification. Viewers could select THX 2D or 3D cinema modes for 2D or 3D movie experiences from broadcast sources and Blu-ray discs. Four new THX-certified 3D JVC projectors were unveiled during this time. These were the Reference Series DLA-RS60 and DLA-RS50, marketed by JVC's Professional Products Company, and the Precision Series DLA-X9 and DLA-X7.

In early 2013, THX unveiled a new app called THX Tune-Up in time for Super Bowl, available on App Store and Google Play. It was billed as the company's first mobile app.

On March 14, 2013, THX filed a lawsuit against Apple Inc., alleging patent infringement, Bloomberg L.P. prior to a federal court in Northern California.

THX expanded to China in 2014 with new offices in Beijing and a partnership with China Film Group Corporation to redefine the cinema experience. The first THX Certified China Giant Screen (CGS) auditoriums opened Shanghai in September of that year.
In December 2014, THX teamed up with Warren Theatres, opening a large theater complex opened in Broken Arrow, Oklahoma on December 23. Each of the 18 auditoriums in this theater was THX certified and two new Grand Infinity Auditoriums were introduced. They were designed by Bill Warren to revolutionize the large format movie-going experience. These auditoriums featured THX Certification, patented deep curved screens, 64-channel Dolby Atmos sound and the first and only 4K laser projector in the United States.

The company was acquired by Razer Inc. in October 2016.

The first THX-certified laptop was released in 2017 dubbed the Razer Blade Pro.
THX introduced Spatial Audio in 2018, a new positional audio solution that was designed to create an immersive 360-degree sound experience through headphones and speakers. The technology would be used on the Kraken gaming headset, which delivered simulated 7.1 surround sound. These headphones were included with a Spatial Audio app. This would be later used on Windows 10 devices.

On May 2, 2018, it was announced that over 200 Cinemark XD locations in the United States and Latin America would feature a THX sound system. These auditoriums featured enormous wall-to-wall screens, crisp, clear digital projection with 2D and 3D capabilities, immersive, surround sound audio systems that enabled customers to hear the movies as the filmmakers intended, premium seats with Luxury Lounger electric recliners, and THX Certification. Both companies first announced the partnership a year prior in 2017. The first THX Ultimate Cinema debuted at Regency Westwood Village in Los Angeles in 2019. This theater provided exhibitors with a branded and differentiated PLF offering that included projection technology from Cinionic, as well as an immersive audio system, acoustics, and auditorium specifications that met THX certification standards.

In September 2020, Walmart stores began to sell Gateway laptops and tablets, which were tuned by THX, ensuring brighter contrast with more rich vibrant screen colors. They combined style, performance, and value in a wide range of products for consumers, students, and creators. The laptops featured THX Spatial Audio that delivered an authentic 7.1 surround experience through built-in speakers and attached headphones.

THX premiered their first consumer electronic product called the Onyx in 2021. This product was a mobile headphone DAC/Amplifier that utilized THX AAA technology.

Mascot

THX's mascot is a robot named Tex. Tex was created by John Lasseter, the head of Pixar Animation Studios, responsible for, among other things, animated films. He first appeared in the original Tex trailer, which premiered in theaters on July 3, 1996, with the theatrical release of ''Independence Day'', in which he fixes up the THX logo. A second trailer called Tex 2: Moo Can premiered in theaters on November 26, 1997, with the original theatrical release of ''Alien Resurrection''. Less than a decade later on June 9, 2006, the Tex 3: Action trailer premiered with the release of ''Cars''. They were later seen in some prints of early Pixar animated films on DVDs including ''Toy Story'', ''A Bug's Life'', ''Toy Story 2'', ''Monsters, Inc.'', ''Finding Nemo'' and ''Cars''. In 2005, the trailers were not shown in the original home media on another Pixar animated feature film, ''The Incredibles'' which used the Cavalcade trailer instead. The Moo Can trailer was also seen on some 20th Century Fox DVDs, such as '' Speed 2: Cruise Control'' and ''The Day the Earth Stood Still''.

On April 16, 2012, THX announced that they would be hosting an online photo contest called Where in the World is Tex. Running from April 23 to May 13, this event challenged fans from around the world to capture and upload their best photo of Tex in and around local THX certified cinemas or well-known city landmarks near those cinemas, and then share them on THX's Facebook page.
