➤ Optimizing the speaker settings automatically (YPAO)

En

If a warning message is displayed after the measurement, you can still save the measurement results by following on-screen instructions.

However, we recommend you perform YPAO again in order to use the unit with the optimal speaker settings.

A speaker cable may be connected with the reverse polarity 
(+/-).

Select “Wiring” in “Result” (p.56) and check the cable connections (+/-) of the speaker identified by 
“Reverse”.
If the speaker is connected incorrectly:
Turn off the unit and then reconnect the speaker cable.
If the speaker is connected correctly:
Depending on the type of speakers or room environment, this message may appear even if the speakers are 
connected correctly. In this case, you can ignore the message.

A speaker is placed more than 24 m (80 ft) from the listening 
position.

Select “Distance” in “Result” (p.55) and move the speaker identified by “>24.00m (>80.0ft)” within 24 m 
(80 ft) of the listening position.

There are significant volume differences between the 
speakers.

Select “Level” in “Result” (p.56) and check the speaker identified by “Over ±10.0dB”, then check the usage 
environment and cable connections (+/-) of each speaker, and the volume of the subwoofer. We recommend 
using the same speakers or speakers with specifications that are as similar as possible.
