ADVANCED OPERATION
The Yamaha Parametric room Acoustic Optimizer
(YPAO) function detects speaker connections, measures
the distances from them to your listening position, and
then automatically optimizes the speaker settings, such as
volume balance and acoustic parameters, to suit your
room.
Note
• The YPAO function of this 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.
• 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.
