AFew Words About THX® pm3™ Certification

Nearly two decades ago, George Lucas turned a passion for great sound into the world’s most accepted and trusted solution for achieving it. The standard was named THX (for Tomlinson Holman, who developed the THX Sound System when he was the research and technical director at LucasArts® in the early 80s), and today, with hundreds of thousands of home theater customers and more than 3000 THX Certified movie theaters enjoying its benefits, the THX name has become nothing short of legendary. Simply put: when it comes to premium sound, no other name so closely defines ‘quality’ for millions of movie- goers and home theater enthusiasts alike.

Today, a new landscape is emerging. A landscape comprised of hundreds of small, professional multi-channel facilities, whose need for differentiation, expert technical and marketing support, and a true, multi-channel standard is becoming a competitive fact of life. Again, THX has a singular solution and this time it’s called THX pm3 Certification.

All facilities involved with mixing and/or monitoring of multi-channel material should have the option to use pm3. THX pm3 Certification is ideal for DVD mastering, sweetening, and mixing; and is also perfect for facilities doing work in broadcast, music, or multi-media applications.
