5 Optimizing the speaker settings automatically (YPAO)
The YPAO microphone (supplied) detects the status of speaker connections and the distance between the speakers and
the listening position, and adjusts the volume balance and the tone settings automatically (YPAO: Yamaha Parametric
room Acoustic Optimizer).
• The volume level is fixed to 0 dB while measuring.
• The test tone is output at a high volume while measuring. Be
careful that the test tone does not frighten any small children.
• The room must be quiet while measuring.
• Do not connect headphones to the unit.
• YPAO measurement does not work correctly if any obstacles are
in the room. Move everything out of the room or place it in the
corners while measuring. It takes approximately three minutes
to finish this measurement.
Preparation before using YPAO
(If necessary) Select the language displayed on the TV screen with
"Language" in the "Setup" menu referring to "Owner's Manual" (p.71).

• When a subwoofer
with the automatic
standby function (turn
off automatically
during no signals
input) is used, disable
the function before
going to the next step.
Set the YPAO microphone at the height
of your ears. We recommend that you
use equipment that allows you to adjust
the height (such as a tripod) as a
microphone stand. If you are using a
tripod, use the tripod screws to fix the
microphone in place.
