AUDIO-TECHNICA PRO44 Microphone

AUDIO-TECHNICA PRO44 Cardioid Condenser Boundary Microphone

The Audio-Technica PRO44 is a cardioid condenser boundary microphone designed for installed-sound applications such as conference tables, podiums, lecterns, and stage floors. Its low-profile half-space design sits flat against any surface and exploits the acoustic boundary effect: when centred on a flat, unobstructed surface, directionality increases by 3 dB for enhanced gain before feedback and improved rejection of ambient noise. The 60° acceptance angle keeps focus tightly on the intended sound source while rejecting off-axis sound, and a rubber non-slip base minimises transmission of surface vibrations.

Key Features

• Half-space cardioid polar pattern with a 60° acceptance angle for focused pickup of speech and sound from the intended source, with strong rejection of ambient noise.
• Boundary placement increases directionality by 3 dB for improved gain before feedback and better signal-to-noise ratio compared to a stand-mounted microphone.
• Low-profile design that sits flat on conference tables, podiums, lecterns, or stage floors for an unobtrusive appearance.
• Rubber non-slip base that minimises mechanical vibration transmission from the mounting surface to the capsule.
• Operates on phantom power (9 to 52V DC), compatible with any standard mixing console or audio interface.
• Handles up to 114 dB SPL before distortion, making it suitable for both speech reinforcement and theatrical stage miking.
