AUTO SETUP

Introduction

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.
Notes
• Loud test tones are output during the auto setup procedure.
Please be ready!
• If auto setup stops and error messages appear on the OSD,
follow the troubleshooting on page 29.
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.
DISTANCE/PHASE
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
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.
