Audio Technica PRO44 Unidirectional Condenser Boundary Microphone - Black
The Audio Technica PRO44 is a Half-Cardioid Condenser Boundary Microphone with a low-profile design, wide-range condenser element and self-contained electronics — ideal for conference tables, podiums, lecterns and installed sound applications where a discreet, high-quality surface-mount microphone is required.
The Audio Technica PRO44 is a professional unidirectional condenser boundary microphone designed for installed sound applications where a low-profile, high-quality and discreet microphone solution is required. Its half-cardioid polar pattern — operating as a cardioid in the hemisphere above the mounting surface — provides focused pickup of sound from above the table or podium surface whilst rejecting sound from below, delivering excellent gain before feedback and clean, intelligible speech reproduction in conference, presentation and installed audio environments. The low-profile design keeps the microphone unobtrusive on any surface, and the rugged construction ensures reliable performance in the demanding day-to-day use of permanent installations.
Ideal for conference tables, boardrooms, podiums, lecterns, courtrooms, houses of worship and any other installed sound environment where a surface-mount boundary microphone is required, the PRO44 combines outstanding sound quality with practical installation features and self-contained electronics that eliminate the need for external power modules — simplifying system design and reducing installation complexity.
Wide-Range Condenser Element
The PRO44 features a fixed-charge back plate, permanently polarized condenser element with a low-mass diaphragm — providing a wide-range frequency response from 70Hz to 16kHz with superior performance and natural, accurate sound reproduction for both speech and music sources. With a high open circuit sensitivity of -25dB (56.2mV), the PRO44 delivers strong output from a boundary microphone for clean, detailed audio capture across conference and installed sound applications.
Practical Detachable Cable
The PRO44 is supplied with a 7.6m (25ft) detachable cable with TA3F and XLR male connectors — providing sufficient cable length for most conference table and podium installation scenarios, and the detachable design allows the cable to be replaced or swapped without replacing the microphone body itself.
