*1 LC3plus is the supported audio format in ECM-S1.
*2 This is the approximate communication distance when the microphone is upright and directly facing the receiver. It varies depending on the surrounding conditions, such as the presence or absence of reflective surfaces or obstacles like metallic objects or human bodies, as well as the radio wave conditions.

*1 Videos recorded with 24-bit audio may not be played back normally on devices or software incompatible with 24-bit audio, resulting in unexpectedly loud volumes or no sound.
*2 Acquired while “8” is selected by the AUDIO LEVEL dial.
*3 Acquired while “DIGITAL” is selected by the slide switch.
*4 Acquired while 
(Monaural, Uni-directional) is selected by the directivity selection switch and “LC” is selected by the filter switch.
*5 Equivalent sound pressure level value converted from the average value of the noise that is output from the microphone when an air stream with a wind velocity of 2 m/sec. is applied to the microphone from every direction. (0 dB = 2×10 -5 Pa)
*6 Equivalent sound pressure level value converted from the input level value that is acquired when 1% waveform distortion is produced by 1 kHz output signals from the microphone. (0 dB = 2×10 -5 Pa)
*7 Time period required for charging the empty rechargeable batteries via the USB charging port (CDP - Charging Downstream Port) on the computer to full capacity. It may vary depending on the using condition.
