PREPARATION
This unit employs YAMAHA Parametric Room Acoustic
Optimizer (YPAO) technology which lets you avoid
troublesome listening-based speaker setup and achieves
highly accurate sound adjustments. The supplied
optimizer microphone collects and analyzes the sound
your speakers produce in your actual listening
environment.
• Please be advised that it is normal for loud test tones to be
output during the auto setup procedure.
• If auto setup stops and an error message(s) appear on the GUI
display, follow the troubleshooting on page 35.
YPAO performs the following checks and makes
appropriate adjustments to give you the best possible
sound from your system.
Wiring
Checks the polarity of each speaker.
Distance
Checks the distance of each speaker from the listening
position and adjusts the timing of each channel.
Size
Checks the speaker’s frequency response and sets the
appropriate low frequency crossover for each channel.
Equalizing
Adjusts frequency and levels of each channel’s parametric
equalizer to reduce coloration across the channels and
create a cohesive sound field. This is particularly
important if you use different brands or sizes of speakers
for some channels or have a room with unique sonic
characteristics.
YPAO equalizing calibration incorporates three
parameters (Frequency, Level and Q factor) for each of the
10 bands in its parametric equalizer (plus 5 subwoofer
bands) to provide highly precise automatic adjustment of
frequency characteristics.
Level
Checks and adjusts the sound level (volume) of each
speaker.
1 Connect the supplied optimizer microphone
to the OPTIMIZER MIC jack on the front
panel.
After you have completed the auto setup procedure, be sure to
disconnect the optimizer microphone. If it is left connected to this
unit, no sound will be output from the speakers.
2 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 tripod (etc.) to affix the optimizer
microphone at the same height as your ears would
be when you are seated in your listening position.
