Details
The PRO 44 is a wide-range condenser microphone with a hemi-cardioid (half-space cardioid) polar pattern. It was designed for surface-mounted applications in high-quality sound reinforcement and other demanding sound pickup situations. Its low-profile design makes the PRO 44 ideal for use in applications where minimum visibility is required.
The PRO44 can be powered from any external 9V to 52V DC phantom power source. A 25' (7.6 m) cable with TA3F and XLRM-type connectors is provided for use between the microphone and electronics input.
Audio-Technica design engineers have utilized the newest low-mass technology in the quest for superior performance. The charge is now on the fixed back plate, rather than the moving element. With the A-T fixed-charge “back plate” construction, a gold-vaporized diaphragm just 2 microns thick (about 0.000079") can be used. This reduces moving mass substantially, improving frequency response and transient response while reducing distortion.
Positioning a properly designed miniature unidirectional microphone centrally on a large, flat, unobstructed surface yields several distinct advantages. Directionality is increased by 3 dB, promoting enhanced gain before feedback and further suppression of ambient noise. Sensitivity is increased for improved signal-to-noise ratio. Phase distortion due to reflected sound energy from the boundary itself is eliminated.
The microphone element is enclosed in a rugged housing with a black finish. The rubber non-slip bottom pad minimizes mechanical coupling of surface vibrations to the microphone.
