The EM 100 DIG is a 100W FM transmitter, microprocessor controlled, that allow a lot of applications like power level control at night to save energy, and the whole monitoring and adjusting of several parameters of the equipment (input level, deviation). EM100DIG includes a high-efficiency amplifier and a restrictive 7-order filter. The switching power supply allows stable output power with input voltages from 90 to 260VAC. EM 100 DIG can be supplied with an internal digital stereo generator board (60dB separation).
