CAD stands for Conneaut Audio Devices. These mics were manufactured in the U.S. at CAD's factory in Conneaut, Ohio. The E-100 mics incorporate a unique electrical design utilizing high speed OpAmps. During transients, these OpAmps require more current than typical phantom power supplies can deliver. Therefore, the mic uses two built-in rechargable batteries to provide the required current. Phantom power is used to simply trickle charge the batteries. The mic can be operated without phantom power for a period of 6 hours on batteries alone. In case you were wondering, the term "servo" refers to circuitry inside the mic which minimizes dc offset and eliminates interstage coupling capacitors.
