Audio-Technica PRO 45 ProPoint Cardioid Condenser Overhead Mic

Hanging cardioid condenser microphones expertly capture large areas of sound, providing full ambience and sound reinforcement for big groups in a way individual mics cannot. The Pro 45 from Audio-Technica was designed for quality sound reinforcement for large performing groups, such as choirs, orchestras or theater stages. High-SPL handling meets the demands of being suspended over choirs and other performing groups. Its uniform 120° angle of acceptance provides well-balanced audio pickup near and far from the mic.

Being sensitive to sound from a wide angle does require some protection. A foam windscreen is included to lower room and vent noise the mic could otherwise pick up. As a condenser microphone, 9V-52V of phantom power is required for operation. Output is low impedance balanced, the signal for which appears across Pins 2 and 3 (Pin 1 is ground). When setting up the mic, position it forward of the front-most source, above the rear-most source, and aim it between them. To create the best sound balance, the distance from the microphone to the rear-most source should not double the distance from the microphone to the front-most source.

Rugged housing has low-reflectance finish, creating a clean look that won’t reflect bright stage lights at the audience. Included with the mic is a 25 foot miniature cable that is permanently attached. The cable’s free end connects to the wall/ceiling plate power module (included) through a TA3F-type connector that optimizes RFI immunity. Also included are a vinyl-coated steel hanger for hanging and a stand adapter so the microphone can be set on the stage if desired.
