UA864 specifications

The Shure UA864 is an advanced antenna designed for wireless microphone systems, specifically engineered to enhance the performance and reliability of audio capture in various environments. Featuring a compact and sleek design, it serves as a vital component in professional audio setups, providing superior signal quality for both live performances and studio recordings.

One of the standout features of the UA864 is its wide frequency range, making it compatible with numerous Shure wireless systems. This versatility allows audio professionals to use it in diverse settings, from concerts to corporate events, without worrying about frequency interference. The UA864 operates optimally in the UHF frequency range, where it effectively captures and transmits high-quality audio signals.

The UA864 boasts a robust construction, ensuring durability in demanding conditions. Its weather-resistant housing makes it suitable for outdoor applications, safeguarding it against environmental factors like moisture and dust. Additionally, its lightweight design facilitates easy installation and transport, making it a preferred choice for touring professionals.

An important characteristic of the UA864 is its specialized polar pattern, which is designed to maximize signal reception while minimizing background noise. This feature is crucial for live performances where capturing clean audio is essential. The antenna’s ability to focus on sound sources and reject unwanted interference contributes significantly to the overall audio quality.

Another notable technology integrated into the UA864 is its DSP processing capability. Digital Signal Processing (DSP) enhances the clarity and intelligibility of audio signals, ensuring consistent sound performance even in challenging acoustical environments. This technology is particularly beneficial for applications where speech intelligibility is critical, such as in conference settings.

Moreover, the UA864 supports both passive and active operation modes, giving users the flexibility to choose the best setup for their specific needs. When used passively, it does not require external power, making it an efficient choice for simpler setups. Conversely, its active mode allows for greater amplification of the signal, ideal for larger venues or when extended coverage is necessary.

In summary, the Shure UA864 is a high-performance antenna characterized by its wide frequency range, durable construction, specialized polar pattern, and innovative DSP capabilities. Its versatility and reliability make it an exceptional choice for audio professionals looking to achieve the best possible sound quality in a variety of settings. Whether for live events, broadcast applications, or studio recordings, the UA864 stands out as a premier solution for enhancing wireless audio performance.
