Shure 27C3115 manual Specifications

27C3115 specifications

The Shure 27C3115 is a dynamic microphone recognized for its robust design and exceptional audio quality, making it a preferred choice among sound professionals. Engineered for versatility, the 27C3115 is well-suited for various applications, including live performances, studio recordings, and broadcast settings.

One of the standout features of the Shure 27C3115 is its frequency response, which is optimized for vocal clarity and detail. The microphone captures a wide range of frequencies, allowing for rich, full-bodied sound reproduction. This characteristic makes it especially effective for vocalists and speakers, capturing nuances that enhance the overall performance.

The Shure 27C3115 employs a cardioid polar pattern, which is crucial for rejecting off-axis noise and feedback. This design enables the microphone to focus on the sound source directly in front of it while minimizing background noise, making it ideal for loud stage environments or situations where control over sound capture is essential.

Another notable technology featured in the 27C3115 is its durable construction. Built to withstand the rigors of daily use, this microphone is encased in a robust metal housing designed to endure rough handling and impact. This feature is vital for touring musicians and audio engineers who need reliable equipment that can withstand the demands of live events.

Additionally, the Shure 27C3115 is equipped with an internal shock mount system that reduces handling noise. This characteristic enhances the overall audio quality, ensuring that even during dynamic performances, the clarity of the sound remains intact. Whether used in a studio or a live setting, the microphone’s ability to minimize noise interference ensures that the primary sound remains prominent.

The 27C3115 also includes features such as a built-in pop filter, which helps to eliminate plosives and sibilance. This technology improves sound quality, making it a versatile option for vocalists and presenters alike.

In summary, the Shure 27C3115 stands out for its exceptional audio quality, durable construction, and advanced technologies. Its cardioid polar pattern, broad frequency response, and features designed to minimize noise make it an outstanding choice for professionals in various audio settings. Whether in live performances or studio recordings, the 27C3115 is a reliable tool for achieving high-quality sound.
