When choosing a microphone for recording vocals, podcasts, or broadcasting, understanding the sound profiles of different models is essential. Two popular options are the Audio-Technica AT2020 and the Shure SM7B. Each microphone offers distinct characteristics that suit different recording needs and environments.
Overview of the AT2020
The Audio-Technica AT2020 is a condenser microphone known for its affordability and clear sound. It features a cardioid polar pattern, which helps isolate the main sound source and reduce background noise. The AT2020 is often praised for its bright, detailed high frequencies and natural midrange response, making it suitable for vocals, acoustic instruments, and studio recordings.
Overview of the Shure SM7B
The Shure SM7B is a dynamic microphone renowned for its smooth, warm sound profile. It also uses a cardioid polar pattern, but its design emphasizes rejection of electromagnetic hum and ambient noise. The SM7B is a favorite among radio hosts, podcasters, and vocalists who seek a rich, professional sound with excellent off-axis rejection.
Sound Profile Comparison
Frequency Response
The AT2020 has a frequency response of 20 Hz to 20 kHz, with a slight boost in the high frequencies, giving it a bright and crisp sound. In contrast, the SM7B has a broader response from 50 Hz to 20 kHz, but it emphasizes the midrange and bass frequencies, resulting in a warmer, more rounded tone.
Sound Characteristics
The AT2020 offers a detailed and transparent sound, making it ideal for capturing vocals with clarity and nuance. Its bright high end can sometimes accentuate sibilance, so it may require EQ adjustments. The SM7B provides a smooth, natural sound with a slight low-mid emphasis, which helps vocals sound fuller and more intimate. It is less sensitive to room acoustics, reducing unwanted background noise.
Practical Considerations
Use Cases
- AT2020: Studio vocals, podcasting, home recording, acoustic instruments
- SM7B: Broadcast, professional vocal recording, podcasting, voice-over work
Setup and Environment
The AT2020 requires phantom power and is best used in controlled environments to minimize background noise. It is lightweight and easy to set up on a standard microphone stand. The SM7B, being a dynamic microphone, does not need phantom power and is more forgiving in less-than-ideal acoustic spaces. It often benefits from a preamp with sufficient gain due to its lower output level.
Conclusion
Choosing between the AT2020 and the Shure SM7B depends on your specific recording needs and environment. The AT2020 excels in capturing detailed, bright vocals suitable for studio settings, while the SM7B offers a warm, natural tone with excellent background noise rejection, making it ideal for professional broadcasting and vocal applications. Both microphones are valuable tools in their respective contexts and can deliver high-quality sound when used appropriately.
