High-Level Sound for High-Level Performance with the LD Systems MON 12 A G3 1200-Watt 12-Inch Powered Coaxial
The MON 12 A G3 W is part of an entirely newly developed family of powered stage monitors for high performance. The MON G3 Series incorporates the advanced technology and premium materials found in high-end monitors typically rented by professionals, making this quality available to everyone. These include, for example, advanced coaxial loudspeakers with integrated 50 x 90 CD horn, which ensure the acoustic ideal of a true point source and thus outstanding audio characteristics even at short listening distances. Besides this, the series offers a high-level of robustness, a comprehensive set of features and the elegant LD Systems design.
For decades, 12″/1″ stage monitors have been the golden mean when it comes to sonority, sound pressure and portability. With coaxial design, smart electronics and a professional look, the MON 12 A G3 W brings this concept into the “modern age”. The ideal dispersion geometry of 50 x 90 for monitor use or 90 x 50 for FOH use make it a multi-talent that offers the right solution for a wealth of different tasks.
Both the signal (XLR/jack combo) and the power connection (PowerCON compatible) can be looped through. This allows for elegant, tidy cabling in multi-monitor set-ups or for distributed sound reinforcement.
