<p>PURPOSE:To prevent misrecordings such as unrecording and incomplete recording, etc., by providing a detecting and warning means for detecting nonloading and imperfect loading of a microphone and also warning as well. CONSTITUTION:The device is provided with a microphone detecting circuit 102 for detecting nonconnection and imperfect connection of the microphone 2 by turning on/off a switch of a microphone jack 101, a warning output circuit 103 for generating an output required for warning by a detected signal of the microphone detecting circuit 102 and a light emitting diode 104 for emitting light by the output from the warning output circuit 103. Consequently, the state of unloading or imperfect loading of the microphone can exactly be recognized by the warning from the detecting and warning means X without monitoring a sound by a recorder at the time of starting the recording. By this method, misrecordings such as unrecording or incomplete recording, etc., at the time of recording are prevented.</p> |
