9Optimizing 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.

The YPAO function of the unit adopts the YPAO-R.S.C. (Reflected Sound Control) technology that enables to create natural sound fields like a room specifically designed for acoustic perfection.

Note the following regarding YPAO measurement.

Test tones are output at high volume and may surprise or frighten small children.
Test tone volume cannot be adjusted.
Keep the room as quiet as possible.
Stay in a corner of the room behind the listening position so that you do not become an obstacle between speakers and the YPAO microphone.
Do not connect headphones.

Press z (receiver power) to turn on the unit.

Turn on the TV and switch the TV input to display video from the unit (HDMI OUT jack).

If you turn on the unit for the first time, the message regarding the network setup appears. For now, press RETURN and proceed to Step 3.

Turn on the subwoofer and set the volume to half. If the crossover frequency is adjustable, set it to maximum.

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 “Manual Setup” ().

To start the measurement, use the Cursor keys to select “Measure” and press ENTER.
The measurement will start in 10 seconds. Press ENTER again to start the measurement immediately.

To cancel the measurement temporarily, press RETURN.

The following screen appears on the TV when the measurement finishes.

If any error message (such as E-1) or warning message (such as W-1) appears, see “Error messages” or “Warning messages”.

To check the measurement results, select “Result”. For details, see “Checking the measurement results”.

Use the Cursor keys to select “Save/Cancel” and press ENTER.

To save the measurement results, use the cursor keys (e/r) to select “SAVE” and press ENTER.

The adjusted speaker settings are applied.

To finish the measurement without saving the result, select “CANCEL”.

Use the Cursor keys (e/r) to select “YES” or “NO” to enable/disable YPAO Volume and press ENTER.

If YPAO Volume is enabled, the high- and low-frequency levels are automatically adjusted according to the volume so that you can enjoy natural sounds even at low volume.
You can also enable/disable YPAO Volume in “YPAO Volume” () in the “Option” menu.

Disconnect the YPAO microphone from the unit.

This completes optimization of the speaker settings.

Caution

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).
