This unit is equipped with a Yamaha Parametric Room Acoustic Optimizer (YPAO) that adjusts the configuration, size, and volume balance of the speakers in order to provide an optimal sound field. 
Using YPAO allows you to automatically configure settings, such as adjusting speaker output and acoustic parameters to suit your listening room (the room in which this unit is placed).
