The Audio-Technica PRO42 is a miniature cardioid condenser boundary microphone engineered for inconspicuous surface-mount use. This microphone provides high-quality sound reinforcement, broadcasting, and recording for boardrooms, schools, government facilities, houses of worship, and other installed applications. It delivers crisp and intelligible audio reproduction for podiums, stages, and conference tables.
The PRO42 features a wide-range condenser element and a low-mass diaphragm to ensure superior performance. The uniform cardioid polar pattern provides maximum rejection of unwanted sounds, enhancing the clarity of the primary sound source. This design makes the microphone suitable for environments requiring precise audio capture and high feedback resistance.
This microphone utilizes a very low-profile design to maintain minimum visibility during use. The rugged construction ensures durability in demanding installation environments. Its compact form factor allows for a discrete presence on any flat surface without obstructing the view of the speaker or the surrounding architecture.
The PRO42 includes self-contained electronics, which eliminates the need for external power modules and simplifies the installation process. For reliable connectivity, the microphone features a 25-foot (7.6 m) permanently attached cable. This cable terminates in a standard XLRM-type connector, making it compatible with a wide range of professional audio equipment.
