STC 4021 Moving Coil Mic.--1935-45

The STC 4021 was made with less acoustical
arrangements than the 4017 but the response at
the upper part of the range is less dependent on
the angle of incidence of the sound, which is an
advantage for the 4021. This mic is more
omni-directional at high frequency than the 4017
