The input from the microphone is too big.
• It may be too close the distance between the speaker and the microphone.
Retry the measurement after setting apart from each other.
• When you use the receiver as a pre-amplifier, either messages may appear, depending the
power amplifier you connect. However, there will be no problems, even if you continue to
use the receiver without changes.
The distance and position of a subwoofer cannot be detected. Or the angle of the speaker
position cannot be detected. This may be caused by noise. Try to perform the measurement
in a quiet environment.
NO WARNING There is no warning information.
No speakers are connected.
Depending on the position of the subwoofer, the measurement results for polarity may vary. However, there will
be no problems even if you continue to use the receiver with that value.
