The IPD10E-R is a self processed and self powered double 10" portable bass system. The internal Minima One amplifier and Infra processing provides for convenient implementation and wiring. The internal Infra integrator, amplifier and loudspeaker process a full range signal into a flat response low frequency acoustic output. The dynamic filter protection threshold is internally preset and eliminates distortion and accidental overload. This insures the maximum output and robust system protection with virtually no audible effect. The input incorporates an InGenius balanced line receiver. This provides 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 for installations to remotely turn the amplifier on and off. Designed for portable use, the IPD10E-R includes handles, black coated steel grille and a pole mount adapter with a durable Ro-Tex finish.
