Renowned for its distinctive design and exceptional sound quality, the SM 7 B has established itself as a prominent player in the audio industry. In this comprehensive review, we will delve into the features and performance of this microphone, while also sharing personal experiences with the SM 7 B.
Design and Build Quality:
Boasting a robust and sturdy construction, the Shure SM 7 B features a metal casing and a suspended capsule that effectively minimizes vibrations. Its classic appearance, with a sleek black color and contrasting silver grille, adds to its timeless appeal. Weighing in at 765 grams, the SM 7 B feels substantial and durable, instilling confidence in its longevity and overall quality.
Frequency Response and Directional Characteristic:
With a frequency response ranging from 50 Hz to 20 kHz, the SM 7 B captures the entire spectrum of human speech and music, resulting in a natural and well-balanced sound reproduction. Unlike some microphones that tend to emphasize certain frequencies, the SM 7 B maintains a neutral and accurate representation of the recorded sound. Additionally, this microphone features a unidirectional (cardioid) directional characteristic, which means it primarily captures sound from the front while minimizing sound from the sides and back.
Sensitivity and Signal-to-Noise Ratio:
Compared to other microphones, the SM 7 B has relatively low sensitivity, requiring more gain to achieve the desired volume. This characteristic proves advantageous when recording in noisy environments, as it effectively reduces the pickup of unwanted background noise. Furthermore, the microphone boasts a high signal-to-noise ratio, ensuring that the desired sound level remains prominent in relation to any background noise. These features make the SM 7 B an excellent choice for professional recordings.
Applications and Performance:
The versatility of the SM 7 B makes it suitable for a wide range of applications, including speech, vocals, instruments, and sound effects. Its exceptional sound quality and ability to minimize background noise have made it particularly popular for podcast recordings and radio broadcasts. When used for vocal recordings, it is often recommended to use a pop filter to reduce plosive sounds. Additionally, the SM 7 B is well-suited for live performances, especially for singers who prefer to be in close proximity to the microphone, as its directional characteristic effectively reduces feedback. Another notable feature of the SM 7 B is its ability to be manually switched between two different impedance settings, ensuring compatibility with a wide range of equipment.
