Power module for AT892 MicroSet. Also suitable for use with any Audio-Technica Wireless Essentials® microphone terminated with 4-pin locking connector. The AT8539 allows you to convert your wireless microphone into a wired model. Comes equipped with a snap-on belt clip.
The Audio Technica AT8539 power module provides several important functions. First, it converts the 11 - 52 VDC phantom power into a smaller DC bias voltage used to power the FET impedance matching circuit inside the microphones listed below. Also, it provides low frequency roll off, supplies battery power if phantom power is not available, converts the signal to the proper impedance and balances the output.
