Passing the THX Test
The THX testing facility room is used for qualitative testing of home theater components. Every receiver, amplifier and pre-amp that is submitted for THX Certification must pass hundreds, in some cases up to 2,000 THX laboratory tests. After passing these tests the component is installed into the demo room.
The THX engineers then play hours of various films and music recordings to ensure the components sound the way they’re supposed to – as the artist intended. It is only after the engineers are happy with what they hear in this room, will the audio component officially receive THX Certification
