AUTO SETUP

Introduction

 

Optimizer microphone 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.

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 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.

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.

1Connect the supplied optimizer microphone to the OPTIMIZER MIC jack on the front panel.

Notes

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.

2Place 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.
