При съемке с подключенным монофоническим микрофоном записывается только левый звуковой канал.
This camcorder is designed to record the left side audio only when a monaural microphone is connected when recording.
Cameras equipped with Multi interface shoe can record audio in both L/R channels with a monaural microphone by attaching the [XLR-K1M] XLR adaptor (sold separately).
Check the XLR-K1M Operation Instructions for details.
