The UNISPHERER I Models 565 are dual impedance unidirectional dynamic microphones shipped connected for low-impedance operation. They can easily be changed to high impedance by internal change of wiring of the output connector. The UNISPHERER I is ideal for use by professional entertainers in high quality theater-stage sound systems and recording , as well as in critical public address systems such as those used in political conventions and legislatures, convention halls, hotels, public auditoriums, stadiums, cathedrals and churches.
Type: Dynamic Frequency Response: 50 - 15,000 Hz Polar Pattern: Cardioid (unidirectional) - uniform with frequency, symmetrical about axis Output Level: Open Circuit Voltage: High impedance: -34.0 dB*, (19.9 mV), Low impedance: -56.0 dB (1.58 mV), * 0 dB = 1V/Pascal
