Optimizing the speaker settings automatically (YPAO)

The Yamaha Parametric room Acoustic Optimizer (YPAO) function detects speaker connections, measures the distances from them to your listening position(s), and then automatically optimizes the speaker settings, such as volume balance and acoustic parameters, to suit your room.

  • Use YPAO after connecting a TV and speakers to the unit.
  • Configure the corresponding speaker settings manually before performing YPAO. For details on the settings, see the following:
  • During the measuring process, test tones are output at high volume, and you cannot adjust the volume.
  • During the measuring process, keep the room as quiet as possible and do not stand between the speakers and the YPAO microphone for accurate measurement.
  • Do not connect headphones.
  1. Press z (receiver power) to turn on the unit.
  1. Turn on the TV and switch the TV input to display video from the unit (HDMI OUT jack).
  1. Turn on the subwoofer and set the volume to half. If the crossover frequency is adjustable, set it to maximum.
  1. Place the YPAO microphone at your listening position and connect it to the YPAO MIC jack on the front panel.
  • Place the YPAO microphone at your listening position (same height as your ears). We recommend the use of a tripod as a microphone stand. You can use the tripod screws to stabilize the microphone.
  • The following screen appears on the TV.
  • To cancel the operation, disconnect the YPAO microphone before starting the measurement.
  • To configure the power amplifier assignment setting, press RETURN and select “Speaker” in the “Setup” menu. For details, see the following:
  1. To start the measurement, press ENTER.
  • The measurement will start in 10 seconds. Press ENTER to start the measurement immediately.
  • The following screen appears on the TV when the measurement finishes.


Warning message (if available)

  • To stop the measurement temporarily, press RETURN.
  • If any error message or warning message appears, see the following:
  1. Confirm the results displayed on the screen.
  • To check the measurement results specifically, select “Measurement result” and press ENTER. For details, see the following:
  1. Use the cursor keys to select “Save” and press ENTER.
  • The adjusted speaker settings are applied.
To finish the measurement without applying the result, select “Cancel”.
  1. Disconnect the YPAO microphone from the unit.
  • This completes optimization of the speaker settings.
  • The YPAO microphone is sensitive to heat, so should not be placed anywhere where it could be exposed to direct sunlight or high temperatures (such as on top of AV equipment).
  • YPAO Volume” in the “Option” menu is automatically enabled after the YPAO measurement. Then, the high- and low-frequency levels are automatically adjusted according to the volume so that you can enjoy natural sounds even at low volume. For details on “YPAO Volume”, see the following:
