A Few 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 Lucasfilm Ltd.™ 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 be-
come 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 land-
scape 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 Certifi-
cation is ideal for DVD mastering, sweetening,
and mixing; and is also perfect for facilities do-
ing work in broadcast, music, or multi-media
applications.
HR624 THX pm3 Certification
When we submitted the HR624s for THX
pm3 Certification, they passed on the first try
with no modifications! (Celebrating with a
jumbo Bucket 'o Popcorn with extra butter is
highly recommended!)
Anyone seeking THX Certification for their
studio, or striving to maintain THX standards,
can use the HR624s and rest assured that their
facility is in full compliance.
