The Opera 712 DX sets the performance standard for other 12“/1“ systems to follow.Feel free to set it up as a fullrange FOH enclosurepair it with subwoofers, or use it as a monitor. But whatever you do with it, rest assured you will enjoy excellent acoustical properties, high sound pressure levels and an impressive audio experience. The recommended subwoofer is the SUB18Ddigipro® technology synchronizes power stages and control circuits, creating an intelligent, responsive protection and supervision system. An integrated processor controls the ongoing interaction between the audio signal, switched-mode power supply, and PWM output stages, and processes key information concerning the status of the internal signal flow from the input to the speakers. digipro® monitors impedance and shuts down in case of short-circuit. Thermal limiters attenuate performance if the unit runs hot.
