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

•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.
