PREPARATION AUTO SETUP AUTO SETUP Introduction Optimizer microphone setup This unit 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 an error message(s) appear on the GUI display, follow the troubleshooting on page 37. YPAO performs the following checks and makes appropriate adjustments to give you the best possible sound from your system. Wiring Checks the polarity of each speaker. Distance 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 10 bands in its parametric equalizer (plus 5 subwoofer bands) to provide highly precise automatic adjustment of frequency characteristics. Level Checks and adjusts the sound level (volume) of each speaker. 1 Connect the supplied optimizer microphone to the OPTIMIZER MIC jack on the front panel.

If it is left connected to this unit, no sound will be output from the speakers. 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 microphone at the same height as your ears would be when you are seated in your listening position.
