“The A1080 includes the YPAO-R.S.C. (Yamaha Parametric Room Acoustic Optimiser – Reflected Sound Control) automated room correction system. It analyses the room acoustics and measures various speaker characteristics using a provided microphone, and then calibrates audio parameters to achieve optimum sound. It applies 64-bit precision EQ calculations to reduce the negative aspects of the room itself, and while not as sophisticated as Dirac, or as user-friendly as Audyssey, it can prove effective.
Unfortunately, despite the updated menus, YPAO retains its dated and confusing UI. So make sure you choose the correct speaker layout (including the overhead or presence channels) and then assign the amps accordingly. YPAO isn’t particularly intuitive compared to Audyssey on a Denon, but the automated EQ routine starts up when you plug in the mic, measuring all the speakers in the system up to eight times. You can take fewer measurements, but the more you do, the more data the system has to analyse.”
