Audio Settings and Recorded Audio Channels on an EOS C700 model

Article ID: ART174771 | Date published: 06/18/2019 | Date last updated: 06/19/2019
 

Description

The camera features 4-channel linear PCM (24 bit, 48 kHz) audio recording and playback. 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 monaural microphone*. The audio signal will be output with the video signal from the SDI OUT terminals, MON. terminals and HDMI OUT terminal. You can record this audio signal on an external recorder.
* Only for recording notes while shooting.

Solution

Audio Settings and Recorded Audio Channels

Which audio inputs are recorded to which audio channels is determined by a combination of menu settings and audio-related controls on the camera.
The following table gives an overview of the possible combinations.

 NOTES
  • On the ALT  [Audio] screen, you can check the audio input source, audio level adjustment mode (A -- automatic/M -- manual) and audio level indicator for each of the audio channels.
 

Connecting an External Microphone or External Audio Input Source to the Camera

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 Ø 3.5 mm stereo mini plug.
Using the supplied microphone holder, you can fix external microphones with a diameter of 19 mm to 24 mm.

Follow the procedure below to attach a microphone (refer also to the following illustration). To connect an external audio device to the camera, plug the device's cable into the desired INPUT terminal (). The following procedure and illustrations assume that the supplied microphone holder is attached to the camera.
​
  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 .
  3. Plug the microphone cable into the desired INPUT terminal  or the MIC terminal .
 
About the monaural microphone
The monaural microphone allows you to add comments while shooting, which can be synchronized to the audio and video during editing.

 NOTES
  • The audio recording level of the monaural microphone is adjusted automatically and cannot be changed.
