THX CERTIFIED AV RECEIVERS

Only the very best AVRs can stand up to the rigorous testing inside THX labs.
Our engineers analyze everything from noise levels and distortion to frequency
response and bass management in over 1,000 laboratory tests. THX Certified
AVRs recreate high impact cinema sound and best-in-class audio fidelity.

WHAT WE TEST

Featured on all Certified Receivers, THX Listening Modes make it
convenient to have one speaker set up for movies, music and games.

POWER OUTPUT

Power output is tested to ensure the receiver accurately plays source material at
THX Reference Level in every input and mode and at every sampling rate for all
possible playback combinations selected by the listener.

BASS MANAGEMENT

THX requires an 80Hz crossover point in the setup menu to ensure proper bass
management in ever y THX Certified AVR. This setting confirms that the subwoofer
handles low frequencies, freeing up the loudspeakers to handle mids and highs.

SIGNAL-TO-NOISE RATIO

THX tests the signal-to-noise ratio to ensure the unit is designed to have low noise
performance with very little to no audible hiss from the speakers.

AV RECEIVER FEATURES

Featured on all Certified Receivers, THX Listening Modes make it
convenient to have one speaker set up for movies, music and games.

RE-EQ

Many movie soundtracks are mixed in studios for playback in large cinema auditoriums
with an array of speakers. When played on home systems, they may appear abrasive and edgy.
Re-EQ establishes a more accurate tonal balance when enjoying movies in your home.

TIMBRE MATCHING

Your ears hear different tonal qualities in sounds coming from different directions.
Timbre Matching restores the frequency balance between your front and surround
speakers ensuring seamless and smooth panning between the front to back of the room.

BOUNDARY GAIN COMPENSATION

Sitting near a wall may result in distorted bass response. BGC corrects the way
low frequency sound is perceived when seated near a wall. This results in a more
accurate bass response.

THX LOUDNESS PLUS

THX Loudness Plus™ is a volume control technology featured in THX Certified
Dominus, THX Certified Ultra and THX Certified Select Certified AV Receivers,
pre-amps and amplifiers that automatically adjusts the front-to-back speaker
level relationship as you turn the volume down. With THX Loudness Plus
home theater audiences can now experience surround sound at any volume level.
