Audyssey MultEQ
Audyssey MultEQ automatically customizes your home theater system to overcome the acoustical problems specific to your room. An optimized audio system gives you the most clear and balanced sound possible.
MultEQ highlights
- Optimize your system. Every room has acoustical problems that affect the sound quality of your home theater system. MultEQ calibrates your speakers and equalizes your system to optimize the sound for your space.
- Clear, accurate, natural sound. With MultEQ, voice and dialog become focused and intelligible, musical balance is restored, musical instruments and sound effects become precisely localized, and surround soundstage is made seamless and enveloping.
- Equalize in minutes. An Audyssey MultEQ calibration is much easier, faster and more accurate than any manual equalization that simply sets speaker levels.
- Four solutions. Audyssey MultEQ comes in four solutions with varying filter resolutions to meet your needs and budget: MultEQ XT32, MultEQ XT, MultEQ and 2EQ. Learn more
- A key component in your AVR. MultEQ ships as a standard feature in products from many of today’s leading home-theater system manufacturers – be sure yours has it.
Audyssey’s room correction solution
Movies, music and games are created in calibrated and acoustically treated rooms and meant to be played back at high volumes in large, acoustic theaters. But reflections from walls and furniture in home theaters and cars distort sound resulting in muddy bass, degraded high frequencies and surround envelopment. Decades of scientific research have gone towards trying to fix the room distortion problem. At Audyssey, we’ve finally solved it.
Based on 6 years and $6 million of research at the USC Immersive Audio Lab, MultEQ is the key enabling technology that delivers sound amazingly close to the original recording. Audyssey MultEQ is a patented method that measures and analyzes the acoustical space to compensate for distortion. MultEQ evaluates everything that causes distortion: frequency response variations and reflections that arrive at different times. AVRs, theaters, cars and studio equipment outfitted with MultEQ use this information to produce a more accurate tonal balance, better bass and more realistic imaging. MultEQ removes distortion so that every audio system – from budget home theaters to world-class cinemas and cars – sounds amazing.

Flavors of MultEQ
Audyssey room correction technology comes in four solutions: MultEQ XT32, MultEQ XT, MultEQ and 2EQ. While they are all built on the same core science, each is designed to operate within the constraints of the available DSP processing power.
 |
MultEQ XT32: Our newest and most accurate room correction solution with more than ten thousand individual control points allowing finer details of the room’s problems to be captured and corrected. The ultra high resolution filters are applied to all channels including the subwoofers, with the most obvious benefit being heard in the low frequency range where correction is needed the most. Expect to find MultEQ XT32 in AVRs starting Fall 2010. |
 |
MultEQ XT: Our advanced resolution room correction solution with high resolution equalization filters for satellites and subwoofers. Most products with MultEQ XT are installer-ready and can be calibrated by an Audyssey Registered Installer to provide even higher performance for even the most demanding large or odd-shaped rooms. |
 |
MultEQ: Our standard resolution room correction solution that uses mid-level resolution filters for satellites and subwoofers. |
 |
2EQ: Our basic resolution room correction solution that uses basic resolution filters for the satellites, but does not apply a filter to the subwoofers. |

What people say about MultEQ
I have never heard such a monumental improvement in the sound of an audio system as I heard with the Denon AVR-5805 with Audyssey's MultEQ engaged. Currently this is the most innovative and advanced room correction system in the industry. It is very promising (and) could set the next trend and evolution in home theater to come.
—Gene DellaSala, President, Audioholics
After calibrating MultEQ Pro you should have little doubt that the customer is hearing anything except his or her speakers: no room or furniture distortion, just audio.
—Ray Coronado, Socalht.com, Los Angeles
MultEQ is based on years of research to measure and remove the key factors that cause acoustical distortion. Our algorithms are the first in the industry to automatically adjust for the problems in the acoustical environment and now we are bringing that technology from the home theater to cars.
