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.
Be aware of the following when using YPAO.
• The amount of time for measurement varies from about two to ten minutes according to settings.
• 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.

• When positioning the microphone, we recommend that you use equipment that allows you
to adjust the height (such as a tripod) as a microphone stand. When using a tripod, use the
tripod screws to fi x the microphone in place.

Opening and closing the front panel door
Before step 4, gently press the bottom of the door to open it.
Keep the door closed when not using controls or jacks behind the front
panel door.
This completes preparation. To achieve more accurate results, take note of the following when
measuring acoustics.
• Keep the room as quiet as possible for a few minutes.
• 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.
