Shure BETA 57A

Shure BETA 57A
The Shure BETA 57A dynamic instrument microphone delivers high gain before feedback in demanding environments. It features a steel grille for increased durability, a shock mount system to minimise the transmission of unwanted noise, and a neodymium magnet for a high signal-to-noise ratio. It maintains a true supercardioid pattern throughout its frequency range, ensuring high gain before feedback, maximum isolation from other sound sources, and minimal off-axis colouration. The highly versatile Beta 57A dynamic microphone provides optimal warmth and presence. Typical applications include drums, guitar combos, brass instruments, woodwind instruments, and vocals.

Microphone Principle
A dynamic microphone is suitable for outdoor performances, live events, music production, etc. It uses a magnet and a moving coil to capture sound.
A condenser microphone is mainly used for studio purposes. It has higher sensitivity and lower noise. It needs to be powered separately.
Frequency Range
The frequency range indicates the range of frequency values that the microphone records. The wider the range, the more sounds it can capture.
Low frequencies (e.g., 20–200Hz): Bass, the lowest notes of instruments (double bass, kick drum) and male voices.
Mid frequencies (e.g., 200–3,000Hz): The body of instruments, the core of the voice where the ear is most sensitive, important for speech clarity.
High frequencies (e.g., 3,000–14,000Hz): Treble, details, sibilance, and the "sparkle" of the sound.
Air band (above 14,000Hz): Gives recordings a sense of expensive, super-high-quality sound and space.
Sensitivity
Microphone sensitivity is the ratio of output voltage to acoustic pressure. It expresses how loud a signal the microphone produces at a given acoustic pressure; higher sensitivity means a stronger voltage and is suitable for quiet studios, while lower sensitivity is better for noisy environments as it unnecessarily amplifies less ambient noise.
