Recording Audio
The camcorder features 4-channel linear PCM audio recording and playback. The sampling frequency is 48 kHz and the audio sampling bit depth is 24 bit. You can record audio using the INPUT terminals (commercially available microphones, analog line-in audio sources, AES/EBU digital audio sources), the MIC terminal (commercially available microphones) or the built-in microphone. 
An audio signal will also be output with the video signal from the SDI terminal and HDMI OUT terminal. You can record this audio signal on an external recorder.

Operating modes:

To each of the INPUT terminals you can attach commercially available microphones, digital audio sources (AES/EBU), or analog line in sources with an XLR connector. To the MIC terminal you can attach commercially available condenser microphones with their own power supply, and a 3.5 mm stereo mini plug. Using the supplied microphone holder, you can fix external microphones with a diameter of 19 mm to 20 mm.

Follow the procedure below to attach a microphone (refer also to the following illustration). To connect an external device to the camcorder, plug the device’s cable into the desired INPUT terminal .
 

1 Loosen the microphone lock screw , open the microphone holder and insert the microphone .

2 Tighten the lock screw and put the microphone cable through the cable clamp under the microphone holder
