Audyssey MultEQ
Professional home theater audio tuning at your fingertips. The latest Denon audio/video products use the Audyssey suite of EQ software for simple, accurate set-up and calibration. With the supplied measuring microphone, Audyssey measures all the speakers in your home theater, and tunes the AV receiver to provide the smoothest, most optimal overall listening experience for your room. Audyssey Dynamic Volume and Audyssey Dynamic EQ smooth out startling jumps in volume (such as TV commercials), letting you listen at lower levels and still enjoy clear dialogue, music, sound effects and precise tonal tailoring. For the enthusiast, the Audyssey MultEQ Editor app lets you view speaker detection data to check the before-and-after results of the Audyssey calibration, making it easy to optimize individual room acoustics to personal taste.
