9 Optimizing the speaker settings automatically (YPAO)
The Yamaha Parametric room Acoustic Optimizer (YPAO) function
detects speaker connections, measures the distances from them to your
listening position(s), and then automatically optimizes the speaker
settings, such as volume balance and acoustic parameters, to suit your
room.
X
The YPAO function of the unit adopts the YPAO-R.S.C. (Reflected Sound Control)
technology that enables to create natural sound fields like a room specifically designed
for acoustic perfection.
Y
Note the following regarding YPAO measurement.
– Test tones are output at high volume and may surprise or frighten small children.
– Test tone volume cannot be adjusted.
– Keep the room as quiet as possible.
– Stay in a corner of the room behind the listening position so that you do not become
an obstacle between speakers and the YPAO microphone.
– Do not connect headphones.
