The Audyssey Pro calibration is available for some higher end Denon/Marantz (up through 2015 models; 2016 and later models use Audyssey App which is considered the Advanced Audio calibration), previous Onkyo/Integra, Audyssey, and NAD components. It takes Audyssey to a much higher level, unlocking more processing power in the process and using a higher grade, individually calibrated microphone. In addition, it offers critical tweaks and flexibility not available in the standard Audyssey calibration, even the XT32 version. If you have an Audyssey Installer ready component, this will give you the most detailed and accurate calibration available. If your system is not Audyssey Pro capable (some XT32 receivers are not), then the Advanced Audio calibration below will give the best results. The calibration cost includes the Audyssey licensing fee of $150.
For other systems (including YAPO, MCACC, Audyssey App, Mini DSP, Emotiva, and others), the Advanced Audio calibration utilizes the manual room equalization and bass management capabilities included in most late model receivers and processors to give a startling improvement over the normal auto setup routines. REW, along with a microphone individually calibrated by Crossland Labs, is used to measure and analyze each speaker. Multiple listener locations can be spatially averaged. The system will be equalized to a "house curve", with a specific high frequency rolloff and slightly elevated bass; and this can be modified to suit individual preferences.
When you just want to know the basics are done right, the Basic Audio setup will get things on the right track.
Average time is 3-5 hours for Audyssey Pro, 5-7 hours for Advanced Audio, 1-2 hours for Basic audio.
