WHAT IS THE REFERENCE LEVEL?

THX Certified Audio products are designed to let you experience movies the way they were meant to be heard. On every THX Certified AV Receiver the “0” on the volume dial represents THX Reference Level, the exact volume level used by the moviemakers and sound artists in the studio.

For manufacturing receivers and speakers, achieving the THX Reference Level is no simple task. It requires a tremendous amount of power to drive an audio system effortlessly without clipping or distorting. To ensure the audio products reach this peak performance THX developed a set of standards as part of its THX Dominus, THX Ultra, THX Select and Integrated System certifications.

  • Experience Studio Clarity: THX Certified Receivers reproduce studio Reference Level, 85dB SPL with 20dB of headroom.
  • Reference Level for your Room: THX Dominus, THX Ultra, THX Select and THX I/S certification categories deliver Reference Level performance in your specific room size.
  • Distortion-free Playback: THX Certified Receivers and speakers are designed to recreate Reference Level with minimal distortion.
