Sound Recording
You can record movies while recording sound with the built-in monaural microphone or an external stereo microphone. You can also freely adjust the sound-recording level.
Use [ : Sound recording] to set sound recording functions.
Caution
- Sounds from Wi-Fi operations may be captured with built-in or external microphones. During sound recording, using the wireless communication function is not recommended.
- When connecting an external microphone or headphones to the camera, be sure to insert the plug all the way in.
- If AF operations are performed or you control the camera or lens during movie recording, the camera's built-in microphone may also record mechanical sounds of the lens or sounds of camera/lens operations. In this case, using an external microphone may reduce these sounds. If the sounds are still distracting with an external microphone, it may be more effective to remove the external microphone from the camera and position it away from the camera and lens.
- Line input up to +6 dBV is supported, but levels higher than the standard input level of –8 dBV may cause worse distortion. Taking test shots in advance is recommended.
- For line input, always set [Sound rec.] to [Line input]. Supplying audio when it is not set to [Line input] may damage the camera.
- Setting the sound recording option to [Line input] disables recording by the built-in movie microphone. Additionally, [Wind filter] and [Attenuator] are not available.
- Noise reduction is not applied to the audio played through headphones. Thus, the audio recorded with the movie will be different.
- Do not change the [Manual] or [Line input] settings when listening with headphones. This may cause sudden loud output that may hurt your ears.
Note
- Audio is also output when the camera is connected to televisions via HDMI, except when [Sound rec.] is set to [Disable]. In case of feedback from television audio output, move the camera away from the television or turn down the volume.
- The sound volume balance between L (left) and R (right) cannot be adjusted.
- Sound is recorded at a 48 kHz/16-bit sampling rate.
Sound Recording/Sound-Recording Level
-
Auto
The sound-recording level is adjusted automatically. Auto level control will take effect automatically in response to the sound level.
-
Manual
You can adjust the sound-recording level as needed. Select [Rec. level] and turn the  dial while looking at the level meter to adjust the sound-recording level. Look at the peak hold indicator, and adjust so that the level meter sometimes lights up on the right of the “12” (–12 dB) mark for the loudest sounds. If it exceeds “0”, the sound will be distorted.
-
Line input
Line input can be used as the audio source. Audio supplied this way is combined with video to record movies. You can adjust the recording level to one of 64 levels. The adjustment method is the same as for [Manual].
-
Disable
Sound will not be recorded.
Wind Filter
Set to [Enable] to reduce wind noise when there is wind outdoors. Only activated when the camera's built-in microphone is used. When the wind filter function takes effect, part of the low bass sounds will also be reduced.
Attenuator
Automatically suppresses sound distortion caused by loud noises. Even if [Sound rec.] is set to [Auto] or [Manual] for recording, sound distortion may still result if there is a very loud sound. In this case, setting it to [Enable] is recommended.
-
Microphone
Normally, monaural sound is recorded with the built-in movie microphone.
Stereo sound can be recorded by connecting an external microphone with a 3.5 mm mini-jack to the camera's external microphone IN terminal (), which the camera will use instead. Using an external microphone such as Directional Stereo Microphone DM-E1 (sold separately) is recommended.
-
Line input
Direct input is supported for line-out stereo sound from mixers or other devices. Audio from a 3.5 mm mini-jack connected to the camera's line input terminal () is combined with video to record movies with stereo sound. The standard input level is –8 dBV. Adjust the audio recording level to suit the line-out level.
-
Headphones
By connecting commercially available headphones with a 3.5 mm mini-jack to the headphone terminal (), you can listen to the sound as movies are recorded. You can listen in stereo to audio from an external stereo microphone. To adjust headphone volume, press the  button, select  , then turn the dial for adjustment ().
You can also use headphones during movie playback.
