The PS12E-I is a self-powered single 12” bass system designed for permanent installation. The PS12E-I provides perfectly flat response down to 8 hertz when used in conjunction with the 8 hertz Integrator. Our external rack mount Infra-MXB Integrator is recommended to drive a line level Infra™ processed signal to one or more PS12E-I systems. The PS12E-I offers a black textured finish, a black coated steel grille and optional fly points. The audio input incorporates an InGenius® balanced line receiver, providing very high common mode rejection, to eliminate noise often present in systems with less optimized grounding and wiring schemes. The internal Minima One™ amplifier incorporates a high efficiency low power consumption green design with advanced digital switching to automatically accept any line voltage from 88 to 270 volts. Low voltage contacts are provided to remotely turn the amplifier on and off.
