The PRO 45 is a wide-range minature condenser microphone with a cardioid polar pattern. It is ideal for suspension over choirs, instrumental groups or theater stages. 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.
