Abstract (en)
[origin: EP1253803A2] The system has at least one measurement microphone (30) for detecting at least one test sound from the loudspeaker unit (20a-20d) and at least one receiver unit (12) in the auto-reproduction device (10) for comparing the phase angle of the test sound produced by the receiver unit with phase angle of the test sound output by the loudspeaker unit and picked up by the measurement microphone. Independent claims are also included for the following: an auto-reproduction device and a method of checking phase angles.
