PREPARATIONS ➤ Optimizing the speaker settings automatically (YPAO) En 42

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.39) 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.

Depending on the type of speakers or room environment, this message may appear even if the speakers are

connected correctly.

W-2: Over Distance

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

position.

Select “Distance” in “Result” (p.39) and move the speaker identified by “>24.0m (>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.
