IC Recorder
ICD-PX470
The volume of the audio you recorded from an external device is low or you hear
squeaking noises when you listen to the audio via the built-in speaker.
If you record audio from a monaural external device that is connected to your IC recorder with a stereo connection cable,
playing the recorded files may sound low in volume or make squeaking noises when you listen to the audio via the built-in
speaker. This is because the left and right audio signal output is reversed in phase, and does not indicate a malfunction.
Be sure to use an audio cable with a monaural plug to record audio from a monaural external device.
