The Heil PR-781 Studio Microphone is a standout choice for amateur radio enthusiasts. It is designed specifically for compatibility with elite transceivers from brands such as Kenwood, Yaesu, Ten-Tec, and Icom. Building on the legacy of its predecessor, the PR-780, the PR-781 delivers professional-quality sound with a dynamic cardioid polar pattern. This microphone was developed in response to a request from ICOM for a superior microphone to complement their iC 7800 radio, resulting in a product that enhances audio clarity and articulation, a hallmark of Heil Sound microphones.

Featuring a comprehensive frequency response of 50 Hz to 16,000 Hz, the PR-781 ensures that users experience rich and detailed audio reproduction. It operates with a balanced output impedance of 600 Ohms and utilizes a low-mass aluminium diaphragm, allowing for precise sound capture. The microphone's output connection is a standard 3-pin XLR, making it versatile for various setups. Additionally, Heil offers compatible shock mounts, including the PRSM and SM-2, to minimize handling noise and improve performance during operation.

For optimal use, the PR-781 requires a CC-1XLR K-Y or I cable tailored for specific transceiver brands. This ensures seamless integration with various models, including Kenwood's TS series and Yaesu's Mk V. With a net weight of 14 ounces and a sleek black satin epoxy finish, the PR-781 combines aesthetics with functionality, making it an excellent choice for both amateur and professional radio applications.
