GENERAL
The UNIDYNE® Ill Models 545D and 545SD are dualimpedance unidirectional, dynamic microphones shipped connected for low-impedance operation. The microphones provide wide range reproduction of music and voice and can be effectively used outdoors and indoors. The UNIDYNE Ill 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. The UNIDYNE III features an exceptionally uniform pickup pattern-provides an effective solution to feedback problems in reverberant locations, permits best utilization of space in small studios, facilitates orchestral placement, and provides practically complete exclusion of unwanted noises. Model 545D is designed for applications where a switch is not required. Model 545SD is equipped with a magnetic reed On-Off switch
