A89SM specifications

The Shure A89SM is a high-performance microphone designed specifically for professional audio applications, especially in theater, broadcast, and live sound settings. This microphone is characterized by its discreet design, making it an excellent choice for situations where visual presence must be minimized without compromising audio quality.

One of the standout features of the A89SM is its small size. At just 5mm in diameter, it can be easily concealed within costumes, headpieces, or mounted to clothing, ensuring that it remains unobtrusive. This is particularly important in theater productions, where actors require mobility without the distraction of visible microphones.

The microphone employs a supercardioid polar pattern, which is designed to capture sound primarily from the front while rejecting ambient noise from the sides and rear. This feature is crucial in noisy environments as it allows for clear audio capture of the desired source, whether that’s an actor’s voice or a musical instrument. The supercardioid pattern ensures that the microphone focuses on the sound source, maintaining clarity and reducing unwanted background interference.

Another key characteristic of the A89SM is its wide frequency response. With a frequency range extending from 20Hz to 20kHz, it is adept at capturing the full spectrum of human speech and musical tones. This broad response enables it to reproduce rich vocal details, making it suitable for both spoken word and musical performances. The microphone also boasts a high maximum sound pressure level (SPL), allowing it to handle loud sound sources without distortion, a vital feature for dynamic performances.

Additionally, the Shure A89SM is engineered with durability in mind. Its robust construction is built to withstand the rigors of live performance, ensuring it can endure the physical demands of touring and stage use. The microphone’s design also incorporates a moisture-resistant coating, enhancing its reliability in varying environmental conditions, thereby protecting it from sweat and humidity.

Compatibility is another significant advantage of the A89SM. It can be seamlessly integrated with Shure wireless systems and other professional audio equipment. This versatility allows sound engineers to incorporate it into existing setups effortlessly, making it an ideal choice for mobile and stationary applications alike.

In summary, the Shure A89SM combines advanced microphone technology with a compact, durable design. Its supercardioid polar pattern, wide frequency response, high SPL capabilities, and moisture resistance make it a powerful tool for audio professionals aiming for exceptional sound quality while maintaining visual discretion. Whether in theater, broadcasting, or any live sound context, the A89SM is a dependable choice that delivers outstanding performance.
