AUTO SETUP
26
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 30.
YPAO performs the following checks and makes 
appropriate adjustments to give you the best possible 
sound from your system.
WIRING/LEVEL:
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.
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.
