PREPARATIONS ➤ Optimizing the speaker settings automatically (YPAO) En 51
Warning messages
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.
Warning message Cause Remedy
W-1: Out of Phase
A speaker cable may be connected with the reverse polarity
(+/-).
Select “Wiring” in “Result” (p.48) and check the cable connections (+/-) of the speaker identified by
“Reverse”. If the speaker is connected incorrectly, turn off the unit and power amplifier, and then reconnect
the speaker cable. 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.
The pin assignments of the XLR jacks of the unit and power
amplifier are not same.
Check the pin assignments of the XLR jacks of the power amplifier. If they are not compatible with the pin
assignments of the unit (p.23), change the pin assignment setting of the power amplifier or use unbalanced
(RCA) connections.
W-2: Over Distance
A speaker is placed more than 24 m (80 ft) from the listening
position.
Select “Distance” in “Result” (p.48) and move the speaker identified by “>24.00m (>80.0ft)” within 24 m (80
ft) of the listening position.
W-3: Level Error
There are significant volume differences between the
speakers.
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.
