Yamaha RX-V2500 Manual Do Proprietário

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.

• 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.

Checks which speakers are connected and the polarity of 
each speaker.

Checks the distance of each speaker from the listening 
position and adjusts the timing of each channel.

Checks the speaker’s frequency response and sets the 
appropriate low frequency crossover for each channel.

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.

Checks and adjusts the sound level (volume) of each 
speaker.

• 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.

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.
