With the YAMAHA Parametric Room Acoustic Optimizer (YPAO) feature, you can avoid troublesome speaker setup and 
achieve highly accurate sound adjustments. The supplied optimizer microphone collects and analyzes the sound that the 
speakers produce in your actual listening environment. We recommend that you perform YPAO each time when you 
change the speaker layout or listening position. To configure the speaker settings manually, refer to “Adjusting the 
Speaker Balance During Playback” (page 64).
YPAO performs the following adjustments:
YPAO performs the following checks and makes 
appropriate adjustments to give you the best possible 
sound from your system.
• Wiring/Polarity
Checks which speakers are connected and the polarity 
of each speaker. Also checks and adjusts the sound 
level (volume) of each speaker so that the sound level 
of each speaker is the same when heard from the 
listening position.
• Distance/Phase
Checks the distance of each speaker from the listening 
position and adjusts the delay of each channel so that 
the sound from each speaker reaches the listening 
position at the same time. Also checks the phase of 
each speaker.
• Size
Checks the speakers frequency response and sets the 
crossover/high cut frequency for the subwoofer to 
improve the sound relationship between the speakers 
and the subwoofer.

The CinemaStation stores speaker settings configured by YPAO 
and manual setup individually. You can switch between them by 
turning on/off the YPAO mode (page 23).
• Since loud test tones will be output during the setup procedure, 
be sure to keep small children out of the room.
• For the best results, make sure the room is as quiet as possible 
during the setup procedure. If there is too much noise, the 
results may not be satisfactory.
• Disconnect the headphones from the 
 SILENT CINEMA 
jack on the CinemaStation before starting the setup procedure. 
• Be sure to disconnect the optimizer microphone when you have 
completed the setup  procedure.
• The optimizer microphone is sensitive to heat. Do not place it 
on top of the CinemaStation or in direct sunlight.
1
Make sure the CinemaStation and subwoofer 
are turned off (in standby mode).
2
Connect the supplied optimizer microphone 
to the YPAO MIC jack on the CinemaStation.
3
Place the optimizer microphone on a flat 
level surface with the omni-directional 
microphone head upward, at your normal 
listening position.
If possible, use a stand such as a tripod to affix the 
optimizer microphone at the same height as your ears 
would be when you are seated in your listening 
position.
y
If your subwoofer has adjustable volume and crossover/high cut 
frequency controls, set the volume low but not minimum 
(as shown below) and set the crossover/high cut frequency to the 
maximum.
