Description
With robust construction and unobtrusive appearance, the PRO 45 and PRO 45W offer versatile sound-reinforcement solutions for speech, theater, orchestra and choir sound reinforcement and recording. The microphones’ high-SPL handling is perfect for suspension over choirs and orchestras. Available in two colors: Black (PRO 45); White (PRO 45W).
The microphone requires 9V to 52V phantom power for operation. The microphone's cardioid polar pattern provides a 120° angle of acceptance. The microphone includes a 7.6 m (25') permanently attached miniature cable with an XLRM-type connector, which allows it to be plugged directly into an XLRF-type jack or cable connector.
The microphone comes equipped with a vinyl-coated steel hanger for positioning over a choir/orchestra/stage. A foam windscreen is also included. The microphone is enclosed in a rugged housing with a low-reflectance black finish. It is also available with white housing, cable, hanger and windscreen as the PRO 45W.
