AUTO SETUP
32
This unit employs the YPAO (YAMAHA Parametric Room Acoustic Optimizer) 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.
YPAO performs the following checks and makes appropriate adjustments to give you the best possible sound from your
system.
Speaker wiring
WIRING
Checks which speakers are connected and the polarity of each speaker.
Speaker distance
DISTANCE
Checks the distance of each speaker from the listening position and adjusts the timing of each channel.
Speaker size
SIZE
Checks the frequency response of each speaker and sets the appropriate low-frequency crossover for each channel.
Parametric equalizer
EQ
Adjusts the frequency and the parametric equalizer level of each channel to reduce coloration across the channels and
create a cohesive sound field. This is particularly important if you use different brands of sizes of speakers for some
channels or have a room with unique sonic characteristics. In addition, the frequency response of each channel is adjusted
in accordance with the sound output from your front speakers.
Volume level
LEVEL
Checks and adjusts the volume level of each speaker.
• Be advised that it is normal for loud test tones to be output during the “AUTO SETUP” procedure.
• If the “AUTO SETUP” procedure stops and an error or warning message appears on your video monitor, see the “AUTO SETUP”
section in “TROUBLESHOOTING” on page 116 for appropriate remedies.
• 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 and do not place it on top of this unit.
Connect the supplied optimizer microphone to the OPTIMIZER MIC jack on the front panel and place it in a suitable
location in your listening room.
y
It is recommended that you 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.
