External Microphone Use: Does adding an external mic eliminate the hiss issue?
The Canon EOS M's internal microphone is notorious for picking up a noticeable hiss, especially in quiet environments. This issue has led many users to explore external microphone solutions. But does adding an external mic truly eliminate the hiss problem? The answer lies in understanding the source of the hiss and how external microphones interact with the camera's audio circuitry.
Understanding the Hiss
The hiss in the Canon EOS M is often attributed to the camera's preamplifier, which amplifies both the desired audio and the inherent electronic noise. This noise becomes more apparent when recording in low-volume settings. External microphones, particularly those with their own preamps, can bypass the camera's internal circuitry, potentially reducing or eliminating the hiss. However, not all external mics are created equal; the quality of the microphone and its preamp plays a critical role in the outcome.
Choosing the Right External Microphone
To effectively combat the hiss, opt for a condenser microphone with a high signal-to-noise ratio (SNR) and a dedicated preamp. Shotgun microphones, like the Rode VideoMic Pro+, or lavalier mics with XLR outputs, such as the Sennheiser MKE 600, are popular choices. Ensure the microphone has a low self-noise specification (ideally below 14 dBA). Additionally, using a microphone with adjustable gain control allows you to fine-tune the input level, minimizing the need for excessive amplification in post-production.
Practical Steps for Implementation
- Connect the Mic: Use a 3.5mm TRS cable or an XLR adapter to connect the external microphone to the camera.
- Adjust Levels: Set the camera's audio input level to manual mode and adjust the gain on the microphone to avoid clipping while maintaining a strong signal.
- Test in Quiet Environments: Record a sample in a silent room to verify that the hiss is reduced or eliminated.
- Monitor in Real-Time: Use headphones to monitor audio during recording, ensuring the hiss is not reintroduced through improper settings.
Potential Pitfalls and Solutions
While external microphones can significantly reduce hiss, they are not a guaranteed fix. Poorly shielded cables or low-quality microphones can introduce new noise sources. Always use balanced cables (XLR) and ensure the microphone is powered correctly. If the hiss persists, consider using a separate audio recorder, like the Zoom H1n, and syncing the audio in post-production. This completely bypasses the camera's audio circuitry, providing the cleanest possible sound.
Adding an external microphone can effectively eliminate the hiss issue on the Canon EOS M, but success depends on the microphone's quality, proper setup, and attention to detail. By investing in the right equipment and following best practices, users can achieve professional-grade audio without the distracting hiss.
