AUTO SETUP

This receiver 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 error messages appear on the screen,
follow the troubleshooting on page 28.
YPAO performs the following checks and makes
appropriate adjustments to give you the best possible
sound from your system.
WIRING:
Checks which speakers are connected and the polarity 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.
DISTANCE:
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.
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
seven bands in its parametric equalizer 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.
• The optimizer microphone is sensitive to heat.
– Keep it away from direct sunlight.
– Do not place it on top of this unit.
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
mic at the same height as your ears would be when
you are seated in your listening position.
