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 applica-
tions.

Anyone seeking THX Certification for their studio,
or striving to maintain THX standards, can use the
HR624 MK2s and rest assured that their facility is in
full compliance.
