How to Use an External Microphone with Your Camera

The use of an external microphone enhances the quality of audio recordings, especially when capturing interviews, events, or video content. Whether you're using a DSLR camera or a camcorder, understanding the process can significantly improve the audio quality of your footage.

Check the Compatibility of Your Camera

Most modern DSLR cameras come equipped with an external mic jack, allowing you to connect a variety of microphones. These jacks are commonly found on the side of the camera, often behind a button or flap to protect it from damage. Check your camera's user manual to locate the exact position of the audio input jack.

Direct Wire Microphone

A direct wire microphone can be connected directly to the camera's audio input. This type of microphone is ideal for hand-held or rifle mics. For a more sophisticated setup, you might opt for a radio mic, where the receiver plugs into the camera and the transmitter unit (and microphone) is carried by the subject, such as a Lavalier microphone worn on a lapel.

Powering Your External Microphone

Most cameras provide a low amount of power (2 V or less) to the external mic jack, which is sufficient for most microphones. However, if your microphone requires more power, it will need to have an internal battery. Examples of such microphones include the Rode VideoMicro. Make sure your microphone is compatible with the power specs of your camera's mic jack.

DSLR Camera Manufacturers and External Mic Compatibility

The compatibility of external microphones with DSLR cameras can vary depending on the manufacturer. For instance, many Canon models offer 3.5 mm stereo jacks for external mics, but some lower-cost models lack these jacks. Additionally, Canon DSLRs provide about 2 V of "plug-in power" on their mic jacks, whereas camcorders do not. Therefore, you can use a microphone that requires external power with your Canon DSLR but not with a camcorder. Check your camera model specifically to ensure compatibility.

Audio Quality Considerations

While an external microphone can greatly improve audio quality, it's important to note that not all DSLR cameras produce excellent audio. For example, the Lumix camera is known for having subpar audio quality. In such cases, consider using an external audio recorder, like an old phone, and syncing the audio in editing. You can often find detailed reviews and user manuals for your camera online.

Summary

Using an external microphone with your camera is a straightforward process, provided your camera model supports it. Ensure that your chosen microphone is compatible with the camera's mic jack, and understand the audio quality specifications of your camera. By taking these steps, you can significantly enhance the audio quality of your recordings, making your content more engaging and professional.
