Pioneer’s exclusive Multi-Channel Acoustic Calibration System (MCACC) delivers an easy-to-use, automatic sound adjustment system to precision-tune your Pioneer and Pioneer Elite receivers with minimal effort.

Every MCACC system comes with a microphone to measure and analyze reverb characteristics. The equalizer optimally adjusts sound parameters to fit the size and shape of your home environment while maintaining the integrity of high-resolution playback without any degradation to the quality of your music.

Simply, power-on your receiver, plug in the microphone, activate the MCACC system, and sit back while the MCACC system fine-tunes your home theater to compensate for differing speaker arrays, furniture, and even ceiling height and shape.

As the world’s first automatic sound acoustic correction technology, Pioneer developed MCACC in a one-of-a-kind collaboration between our sound engineers and London’s revered AIR Studios engineers. Building on our 75-year heritage as an audio company, this joint effort resulted in an exclusive technology, licensed and available only on Pioneer systems.

Designed to take full advantage of a complete range of speakers used in home theater systems, producing a professional level of fine-tuning while requiring minimal effort for setup.

One breakthrough was the introduction of Phase Control, an exclusive technology that compensates for lag in low-frequency signals, maximizing multi-channel sound performance and correcting distortion, significantly improving the overall experience.
