Audyssey Room Correction

Every listening room has its own characteristics and acoustical problems. That's why Denon equipped the AVR-S640H with the advanced Audyssey MultEQ automatic room acoustic correction system. Via the supplied measuring microphone and mic stand, Audyssey MultEQ measures all the speakers in your home theater during setup, including the subwoofer, and then generates multiple high precision DSP room acoustic correction filters, which together provide smoothest and most natural tonal balance, regardless of the brand or model of the various speakers. Audyssey Dynamic Volume smooths out annoying jumps in volume (such as TV commercials), letting you listen at lower levels and still enjoy clear dialogue, music, and sound effects. Audyssey Dynamic EQ provides precision tonal tailoring for full range clarity at any listening level.

The Audyssey MultEQ Editor App

The latest Denon audio video products use Audyssey MultEQ for simple, accurate setup and calibration of your system to the room in which it's used. But now you can go further with the Audyssey MultEQ Editor app, going "under the hood" to view and adjust settings for detailed tuning – allowing you to customize the sound more precisely to the specific problems in your room, and tailor the sound to your personal preferences. With this comprehensive app, you can harness the power of Audyssey MultEQ to take total control of the way your home cinema sounds.

This app will allow you to:

  • - View the speaker detection results, to check correct installation.
  • - View before and after results of the Audyssey calibration, making it easy to identify room problems.
  • - Edit the Audyssey target curve for each channel pair to suit your tastes.
  • - Adjust the EQ frequency adjustment range for each channel pair.
