Lite info jag hittade i en recension! Mysterious battery noises some people heard in the H4. [Ed. Note: Samson, Zoom's US distributor, replies, "The 700Hz pulsing is caused by the DC-DC converter when the H4 is working by battery. While this is not a 'mystery' per se, our engineers have only been able to duplicate the issue using very high gain levels [while] recording essentially silence."]
