Set up the speaker parameters automatically (YPAO)
When all connections are complete, adjust the confi guration, sizes, and volume
balance of the speakers to provide an optimal sound fi eld. This unit is equipped with a
Yamaha Parametric Room Acoustic Optimizer (YPAO) function that adjusts the speaker
balance automatically with a simple procedure.
When using YPAO, a test tone will be output from the speakers for approximately 3 minutes to measure acoustics. Be aware of the following when
using YPAO.
• The test tone is output at high volume. Refrain from using this function at night when it may be a nuisance to others.
• Take care that the test tone does not frighten small children.
YPAO operations can be viewed on the front panel display or TV screen. TV display is used here to explain operation.

This completes preparation. To achieve more accurate results, take note of the following when measuring acoustics.
• It takes approximately 3 minutes to accurately measure acoustics. Keep the room as quiet as possible while acoustics are measured.
• Wait in a corner of the room, or leave it entirely, while acoustics are measured to avoid creating an obstruction between the speakers and
the YPAO microphone.
Subwoofer
• The power is turned on.
• Volume is set to approximately half, and the
cross-over frequency (if present) is set to
maximum.
"Mic On. View ON SCREEN" appears on
